911 (991) Porsche 911 (991) - First Drives/Test Thread

The Porsche 991 is the seventh generation of the Porsche 911 sports car. Predecessor: Porsche 911 (997). Successor: Porsche 911 (992). Production: 2011-2019.
In terms of overwhelmingly compelling aesthetic qualities, there are IMHO 3 German automobiles that stand above all else:

The big existential question that Porsche surely asked itself when developing the new generation of 911 is: what is it that makes a car a Porsche 911? This is a question without a right or wrong answer -- it's a matter of perspective.

One suspects the marketing folks would say that it's a car with a curved roof line and round headlights, with a flat-six engine mounted behind the rear wheels and the ignition key located to the left of the steering wheel. A 911 is exquisitely well crafted and offers supercar performance with everyday usability, uncommon reliability, and unmatched fuel economy. A broad product portfolio-there were twenty-three variants of the last 911, not including transmission choice-helps it find home after expensive home, and a half-century history of constant evolution and racing provides a historical backdrop unlike any other sports car.

There's another view, of course -- the one from the driver's seat. From that perspective, the 911 is a pure sports car; a one-of-a-kind combination of modern-car refinement with old-school involvement, as engaging at 15 mph as it is stressful at 150. That it can achieve what supercars can achieve is the triumph of brilliant engineering overcoming a seemingly insurmountable design flaw: it is outspokenly and unabashedly rear-engined. From the parking spot to the flat-out Autobahn run, it never stops reminding its driver of the caged animal behind the rear wheels. The steering wheel bounds about nervously in the driver's hands, constantly reacting to the rear-mounted animal's every motion. The front end bobs up and down quickly -- a reminder that there's no engine there to dampen the suspension's motions -- and the front wheels follow every dip and groove and camber change, doing everything they can to get another inch further from the scary engine in back. All the while, the rear of the 911 dances around, bouncing left and right, as the animal tries to free itself from its mounts.

In the past, both of these views did indeed define a Porsche 911. Beginning February 4, 2012, that's no longer the case. The day the 991-series 911 goes on sale, the marketing view becomes the only view. The 991 is, from that view, the best 911 Porsche has ever made.

As an everyday car capable of reality-bending performance, the two 2012 911 Carrera S models we drove (one with a manual transmission, one with a PDK dual-clutch automatic) easily trump the previous 911. Indeed, Porsche boasts that the S is capable of lapping the Nuerburgring Nordschleife in seven minutes, forty seconds, a full fourteen seconds faster than before. That's as fast as the old GT3. Using the PDK's launch control function, if you're devoid of mechanical sympathy, means you can ride along as the Carrera S catapults itself to 60 mph in as little as 3.9 seconds. (Or 4.3 seconds with the manual transmission.) And unlike previous 911s, this happens with no wheel hop at all.

Even the base model 911 Carrera puts down scorching numbers, according to its makers: the dash to 60 happens between 4.2 and 4.6 short seconds. The new Carrera S keeps its 3.8-liter displacement, but receives the same high-rpm breathing help and experiences the same rev bumps to make 15 more horsepower and 15 more lb-ft of torque than before, for totals of 400 and 325, respectively.

Either engine can be combined with a new seven-speed dual-clutch automatic or a seven-speed manual, the latter an industry first. Surprisingly, the seven-speed stick isn't at all confusing to use: a clever solenioid-based lockout prevents access to the seventh-gear gate unless you've already engaged fifth or sixth. And thanks to a strong spring that returns the shifter positively to the three-four gate, multiple-gear downshifts out of seventh gear are no problem. And those downshifts are surprisingly unnecessary: it's a long gear (70 mph is approximately 2000 rpm) but the 3.8's ample low-end torque means it'll climb significant grades at highway speeds.

As before, the PDK transmission provides seamless acceleration and follows driver's commands obediently via steering-wheel mounted shift paddles. The paddles are conventionally operated, meaning a tug at the right paddle requests an upshift; the left paddle is used for downshifts. Our pre-production PDK occasionally clunked into gear, but we suspect all the bugs will be sorted by the time the 911 hits dealers. No matter how good the PDK, our first choice for any 911 would be the stick shift, anyway: it's a pleasure to use, with light, accurate throws. And though the long-travel pedal is heavy and offset too far to the right, the clutch itself engages progressively and positively. Add in immediate throttle response, and, like the 997, the calibration of the manual transmission is one of the best parts of this Porsche.

And we haven't gotten to the spicy stuff yet: twenty-inch wheels, active engine mounts, active roll stabilization and adaptive suspension are all options-and they were all on the 911 we drove. To call the new car a quantum leap in vehicle dynamics is an understatement. The ride is smoother than many luxury cars, but there are no wasted body motions. Body roll has been all but completely eliminated, and brake dive and squat are fractions of what they were before. The 991 will understeer if you ask it to; it'll oversteer if you ask it to, but if left to its own devices, it remains neutral. This is something no 911 has ever done.

Grade changes, camber changes, throttle changes-nothing upsets the 991. It turns in with the immediacy of a mid-engine car, puts power down with the traction of a four-wheel-drive car, and reacts with the gentleness of a front-engine, rear-wheel drive car. Quick directional changes induce no drama, and never, ever, does the steering feel nervous.

And this is exactly why the purists are going to be upset.

The 911 doesn't drive like other 911s. You never, ever feel the engine's weight move the back end around. The front end doesn't bob, heave, or wander. And when you're cruising down a road, the steering wheel doesn't dance in your hand.

Oh, the steering is perfectly accurate, and its weighting is just like old 911's. Driven in anger, it starts to transmit information about the road surface -- but whereas the last 911's steering screamed at you, this one barely whispers.

What's to blame? Electric power steering. Porsche says that the EPS system weighs about as much as the old hydraulic system, and that it contributes to a one-third-MPG fuel savings. Clearly that's not sufficient reason to abandon the old hydraulic pump and lines, especially since the 911 was already the lightest and most fuel efficient vehicle in its class.

Poke the engineers long enough, and they'll admit that they received complaints about the 997's steering being too nervous. It transmitted too much, they say. Specifically, too much vibration and too many "disruptions." Those disruptions -- to the vehicle's path, presumably -- are bad engineering. They are old-fashioned and needed to be removed. Or at least that's what the engineers believed.

Uh oh, now we're having a Lost In Translation moment. What the engineers are calling "bad engineering" we refer to as "on-center steering feel." Not only do we think of it as a good thing, it was indeed the best thing about the last 911, at least when it was driven on the road. No other steering on earth felt so alive, so connected. Frankly, the steering was the reason we loved the 997 so much-and it set the 911 apart from all of its competition, especially the Audi R8.

It turns out that German customers complained about the steering. And we do understand that: the 997 was a nervous scamp at autobahn speeds. You can drive an R8 at 180 mph and not break a sweat-the 997's tail wagged back and forth constantly, and you felt every millimeter of movement in the steering wheel.

We don't have autobahns in the U.S. and after Porsche got through a huge presentation explaining that the U.S. market is "easily the most important market for the 911," we were pretty surprised that they engineered out our very favorite part of the 911.

There are plenty of other cars on the road that can cruise at 70 mph effortlessly -- the world didn't need another one of those. At our pathetically slow highway speeds, we need everything we can get to make driving fun -- crazy steering feel, an engaging manual transmission, and a car that's perhaps a little bit flawed.

If you've ever driven a Porsche 911, you'll immediately know that the 991 is different. In quantifiable terms, it's leaps and bounds better than any previous 911. It sounds even better, it rides even better, it feels even better, it's even more comfortable, better equipped, and it's far better looking. But if you adored the drive in that 911 because it was a car unlike any other -- because it constantly reminded you that it wanted to kill you, even if it never was going to -- you'll know why the 911 is a better car, but it's not a better 911.

Not necessarily. Dimensions of both cars are virtually similar. With the 991 the whole composition of the engine balance has been altered and the car is more biased to behaving like a mid-engined car.
 
2012 Porsche 911 Carrera S 3.8 PDK review and pictures | evo

The all-new 991 iteration of the Porsche 911 coupe, driven for the first time in Carrera S form. But has it been worth the wait?

What is it?

The 2012 Porsche 911 Carrera, codenamed 991 for no particular reason other than Porsche is running out of codenames beginning with '9, and this one was still available, for now available as a rear-drive coupe but soon to be joined by a full pipeline of variants. The standard Carrera uses a direct-injection 3.4-litre 350bhp flat-six de-stroked from the old 3.6-litre for fuel savings, while the Carrera S has a 394bhp 3.8-litre that is mostly carry-over. The seven-speed comes as a paddle-shift PDK or, intriguingly, as a manual with an extra dog-leg to the far right for the economy cruising gear.

It's on sale in Europe next year, but we've already driven it in the USA.

Technical Highlights?

Many colours are available, but all will be green(er). Aluminum bodyshell content rises to 45 percent now that the roof, floor, doors, bonnet, front wings, and forward crash box are all alloy. That holds the kerbweights down to just under those of the previous model.

On a longer wheelbase with a lower roof and wider front track, Porsche is trying out several new technologies aimed at saving fuel, including its first use of electric power steering. This risky dalliance with a known buzz-kill uses a rack-mounted motor and extensive control logic to filter out unwanted 'noise' through the steering while preserving what's we're told is 'useful' feedback. More petrol pinching comes from stop/start, deceleration-only battery charging, and a coast-at-idle function for PDK-equipped cars that decouples the engine in some coasting scenarios. For handling, a new active anti-roll bar uses compact hydraulic cylinders in place of stabilizer-bar links to help keep the car flatter through corners, plus a torque vectoring system that selectively activates the rear brakes in concert with a locking differential, mechanical or electronic depending on the configuration, for aiming the car at apexes.

What’s it like to drive?

It’s only 30mm longer overall, but with the windscreen center point moved out 75mm over a deeper dash, and a sloping center console evocative of the Panamera’s, the new 911 feels much bigger from the captain’s chair.

Some of the old 911's intimacy is lost, but road noise drops considerably inside (at 80 mph you can hear the Sport Chrono clock ticking, for example) and functionality and comfort both rise - even for the long-suffering back seat passengers, who get another 30mm of legroom.

The longer wheelbase and more equitable axle-weight distribution does as advertised and imparts greater stability, so there’s less vertical bounding through turns and better front-end bite out of the corners. Note: we drove only the 3.8 equipped with the optional dynamic engine mounts, which in the previous car helped greatly in keeping the arse planted.

The steering is indeed more filtered, with most of the hyper-organic jiggles and tugging tossed out. There's still a progressive ramp-up in steering effort that feels natural enough for a car that sells mainly to older folk who aren’t cross-shopping an Exige. The brakes are solid and trustworthy, and they and the differential give the new 911 a sharp lift-throttle turn-in that it never had before.

How does it compare?

People who have always wanted a 911 shouldn’t feel that they’ve missed their moment. The 991 is smoother, quieter, larger, more comfortable on a long drive, but it’s still fundamentally a 911.

So the basic arguments for and against remain the same if you’re looking at, say, the Jag XKR, the Maserati Gran Turismo, or a used Aston. It may be less exotic, but the 911 remains a blue-chip choice and more of an engineering wonder than its rivals.

Anything else I should know?

Porsche has been masterful at expanding the roles the 911 can play, from cushy around-towner for solicitors to hell-spitting track demon. It’ll be interesting to see how this luxed-up enviro-911 morphs into a GT3, or even a GT2. Assuming such things aren’t banned in the coming years.

+ Looks like a 911 but has fewer of its strange tendencies

- How are they going to make the hardcore versions quicker?

You know it's a superb car if CH says it. I'm not worried at all, in fact I think the new 991 will set standards EVERYWHERE.
 
Edmunds - IL Track Tested: 2012 Porsche 911 Carrera S



An all-new Porsche 911 doesn't come around too often, so when one finally arrives we don't waste any time getting down to business with it. The minute we secured the keys to a 2012 Porsche 911 Carrera S we headed straight to the test track to run numbers on the redesigned coupe.

Since it's a Carrera S, it features the 3.8-liter flat-6 tuned to produce 394 horsepower and 325 pound-feet of torque. And since we're not big fans of automatics, we requested a 911 with one of Porsche's new seven-speed manual gearboxes. It won't run numbers as quick as a PDK-equipped car, but it has seven speeds; we had to try it. Later we'll get the automatic, which is the only way to get a 911 with launch control. For now, take a look at these numbers and see what you think. Is this 911 one for the ages?

Tester's comments:

Acceleration: Biggest news here is that the 911 no longer produces its trademark axle-hopping launch. Instead, it merely hazed the rear tires and resisted bogging down the engine once the tires hooked up. Shifter feels a little vague in that I rarely trusted my 2-3 shift, yet it always went in. Tall gearing -- needed 3rd for quarter-mile. (All runs done in Sport Plus mode with exhaust open.) Also felt some sort of shift-shock reduction with each upshift that wouldn't allow chirp. Shifts were smooth but slightly delayed.

Braking: Medium-firm pedal with moderate jump-in but amazing power and effectiveness toward the end of the stop. Very little dive (firm suspension setting), not wiggle, and distances grew shorter with some heat in the brakes. No fade at all.

Slalom: Quick turn-in but a small delay in yaw reaction. Tracks very true to steering input but requires a little patience for the chassis to catch up. Never felt threatening or apt to spin -- even with drop-throttle. Had to be prudent with throttle at exit, but it sure feels like there's an LSD back there making sure all the power is used effectively.

Skid pad: One of a handful of cars that oversteers comfortably, confidently, precisely all the way around the circle. Steering weight comes and goes with front grip level, but the graininess/feel is no longer there. I could steer with the throttle all the way around.

My favorite reviewer EVER. Chris Harris...

What are you talking about? Chris Harris knows nothing about cars, is completely dull on camera, hasn't driven anywhere near as many cars as some members here and can't drive nearly as well as us GCF forum folk.

His opinion is dogshit, as is that of the publication he works for. EVO? Pah! What do they know about driving cars? Rather, we should all go out and drive the 991 for ourselves (like wee little pansies) in order to form a credible opinion.

;)
 
Honest review by Chris. What begs the question is whether Porsche will forego the drive-by-wire steering on the analog GT3.
 
InsideLine pits the 991 vs the Audi R8.

Inside Line tests hundreds of vehicles a year. Cars, trucks, SUVs, we run them all, and the numbers always tell a story. With that in mind we present "IL Track Tested," a quick rundown of all the data we collect at the track, along with comments direct from the test drivers. Enjoy.

There are plenty of sports cars that have tried to dethrone the Porsche 911 over the years. Not many of them have succeeded. Sure, some are faster, some are cheaper and others are more distinctive-looking, but the 911 can still hold its own after all these years.

Now there's a new 911 so it's time to resurrect all those rivalries once again. This time, however, there's a new threat to Porsche's dominance. The Audi R8 burst on the scene in 2008 and has remained a sought-after sports car ever since. Between its distinctive looks and high-revving V8 and V10 engines, the R8 is more than a match for Porsche's finest.

Some would say it's not a fair fight. The standard Audi R8 has two more cylinders, 36 more horsepower and a price tag well in excess of $100,000 compared to the Carrera S. Then again, the Porsche 911 is the king here and the R8 the challenger. Care to guess which one rules at the track?

Tester's comments:

Acceleration: Even with a quick 5K clutch engagement (traction control off), the AWD pulls the engine down and it bogs momentarily before it hooks up. Gated shifter is a nonissue -- never missed a gate. Gearing is a little short (needed to grab 4th for quarter-mile) despite high redline.

Braking: Medium-firm pedal with immediate jump-in. Straight, quiet, obviously fade-free. Very little dive with shocks in firm setting.

Slalom: I'd call this car "very pointy," as it has both an amazingly quick turn-in, plus immediate yaw response. I did find extra rotation with throttle lift, but it hardly needs it. Used AWD at exit with wide-open throttle to "leap" for the last gate. Few other cars feel this confident at this speed -- maybe none.

Skid pad: Neutral right up to the point where it begins to understeer. I tried to pedal it to coax some rotation, but it refused. With ESC on, it used subtle brake applications to reduce understeer at the limit for a slightly better result. Steering feel is very good. Both weight and granularity inform the driver exactly what the front tires are experiencing and broadcasting.

We thrashed the new 2012 Porsche 911 Carrera S at the track and then we tossed it at some curvaceous mountain roads. Now it's time to give the 911 a much-needed rest and hoist it up on our new Rotary two-post lift for a clear look at the suspension that does the business.

This new 911 is in fact a 991 in the language of Porsche engineering, which is why the 991 prefix appears on the various components we'll soon see. You may also notice a bit of grit and grime under there because the roads were wet much of the time we had it -- except at the track, thank goodness.

Let's get on with it. Here's the 411 on the new 911 suspension.

From here we see what looks like the standard 911 setup: humungous brakes and a MacPherson strut suspension

A forged aluminum front knuckle (orange) grasps the bottom of the coil-over strut. Like other 911s before it, the 991's steering (yellow) meets it up ahead of the front axle's centerline.

It's electric power steering this time out, but the components are buried beneath covers we don't dare remove. Steering feel earned mixed reviews, but steering accuracy and direct response are as good or better than what we've found in the model it replaces.

The lower control arm is partially hidden by a convoluted bit of ductwork that sends cooling, soothing relief to the brakes.

A lateral link and a tension link come together in a bolted joint to make that lower control arm. Forged aluminum, of course.

As we've seen before, the front stabilizer bar loops over the top of the lower control arm to meet up with the stabilizer link (yellow,) but here that link is something very special, indeed.

Meanwhile, the damper within the strut housing is fitted with PASM (Porsche Active Stability Management,) a continuously variable damping system with two driver-selectable operating ranges, Normal and Sport.

The stabilizer bar link (green) is hydraulic, as is its opposite number on the other side of the car. A central computer looks at body height sensors, steering angle and a host of other factors to determine how to make them behave.

On straight roads they can go limp to essentially remove the stabilizer bar from the picture for a smooth ride. In corners they can be made to "overdrive" what the stabilizer bar could otherwise do on its own to utterly eliminate body roll. Or the computer can dial in any amount of roll stiffness in between, and it can change its mind in real time as road conditions or driver inputs fluctuate.

Porsche calls this Porsche Dynamic Chassis Control (PDCC) and it's the first time they've fit it to a 911-series vehicle. Whatever you call it, it flat works. This very car pulled 1.04 g on our skidpad, and some of the credit has to be put down to the way this system can make use of all four tires instead of leaning heavily on the outside ones.

You could theoretically achieve the same skidpad prowess with a pair of very big stabilizer bars, but then the car would ride like Grade A dog doo. Conversely, a hydraulic anti-roll system such as this doesn't need a physical stabilizer in between the left and right struts at all, but in that case there'd be no fail-safe if the system developed a fault.

As for those looming red brakes, the massive 6-piston Brembo calipers have a pair of fixed bridges (yellow) for maximum caliper stiffness. This means the calipers have to come off when it's time to change the brake pads which, incidentally, are equipped with electronic pad wear sensors.

And now we know what these big hoses (green) are for: they feed hydraulic fluid to the PDCC active stabilizer bar struts.

This sensor, along with three more at the other suspension corners, measures the position of the lower control arm to deduce the position of the tire.

The PDCC system compares the readings to that generated on the other side to measure body roll, and the PASM active damping system uses them to understand the motions of the wheels in order to determine the amount of damping required, be it for ride, cornering, dive/squat, etc. It's likely the headlights use 'em too for auto-leveling.

It sounded incredible in that last video. I noticed one integrated into the instrument cluster and the other was on the center of the dash. I cant see how 2 nav screens would help.
 
First drive: 2012 porsche 911 carrera s [review]

By Drew JohnsonWednesday, Nov 30th, 2011

It’s a running joke in the automotive world that the person in charge of styling the next Porsche 911 has the easiest job in the industry. But, in reality, that task is one of the most difficult. Unlike most cars, Porsche has to walk a fine line with the 911, keeping faithful to the car’s decades-olds shape while still moving the overall design forward.

And, as if that charge wasn’t difficult enough, Porsche engineers have to ensure the 911 can live up to its modern rivals, despite the limitations of a six-cylinder engine and a rear-engine layout.

So, has Porsche kept true to the 911′s winning formula, or has age finally caught up with the timeless wonder? Let’s find out.

Deja vu all over again
At first glance, it doesn’t appear much has changed for the latest 911, internally known as the 991. The 2012 911 greets you with a familiar face and the same overall shape that has been a 911 staple since its introduction at the 1963 Fankfurt Motor Show. But looks can be deceiving as the 991 is actually a clean-slate redesign, retaining just 5 percent of the parts from the previous-generation 997.

The 991 is longer, wider and lower than its predecessor, but it still takes a discerning eye to differentiate the two at a distance. Up front a closer inspection will reveal that the 2012 911′s headlights are actually mounted farther towards the corners – a direct result of the car’s wider stance. The 991′s lower bumper has also been reworked to fit larger air inlets and LED running lights.

Out back the changes are more obvious, thanks to thinner taillights that Porsche says harken back to the car’s original design. The rear glass section of the 991 is also more tapered than before, combining with accentuated haunches to give the car an overall planted look.

The 991′s roofline has also been lowered by 10mm.

Our 911 Carrera S test car was fitted with 20-inch wheels, although 19s are standard on the base Carrera.

Keeping it in the family
Anyone that has spent any time in a Cayenne or Panamera will feel right at home in the cockpit of the 2012 911. The car’s familial ties are quite evident, especially when it comes to the center stack. Although we’d like to see a little more individuality when it comes to the 911, we found the car’s interior to work well overall.

As is appropriate for a 911, the driver is greeted by a five-gauge dash cluster, with the tachometer located front and center. Just to the right of the tach resides a TFT screen, which can display helpful information like how many Gs you pulled in that last corner. For those a little more concerned with the destination rather than the journey, the screen can also display turn-by-turn directions from the vehicle’s navigation system.

Our test car came fitted with a sports steering wheel, which we think is as a must-have for PDK-equipped cars. Although you lose the multi-function of the standard wheel, the sports wheel not only looks better, but also includes true paddle shifters. We also like that Porsche incorporated “Sport,” “Sport Plus” and “Launch Control” indicator lights on the spindles of the wheel.

The 991′s center stacked is topped with a navigation screen, followed by controls for the car’s audio system. While we found it a bit tricky to use the car’s iPod integration, the overall audio system is fairly intuitive, and we love any car that still uses a good ol’ fashioned volume knob.

Move farther down the center stack and you’ll find the car’s HVAC controls. Thanks to the 911′s German engineering, the controls are straightforward and easy to use, with toggle switches giving just the hint of a jet-fighter. Our only confusion was mentally converting Celsius to Fahrenheit as our test car was German-spec.

The 911′s gear lever is just about a perfect arm’s reach away, but that will likely only come into play for those that opt for the car’s new seven-speed gearbox. We were unable to sample the seven-speed unit during this first drive, but we look forward to testing it in the coming weeks.

Just behind the gear level are controls for the car’s suspension, traction control and exhaust, but we found it odd that Porsche would leave three button blanks. Those empty spots will probably be occupied in at least one of the 911′s 23 planned variants, but it just comes across as cheap in a car that isn’t.

We found our tester’s optional sports seats to be quite comfortable, thanks in large to adjustable bolsters and thigh support. The same can’t be said for the 911′s rear seats, but at least anyone back there will have a good view of the car’s leather-trimmed interior and suede headliner.

The oily bits
Although the engine is no longer visible in the 2012 911 Carrera S, Porsche assures us that a revised 3.8-liter flat-six resides behind the car’s rear axle. Power now stands at an even 400 horsepower – up 15 from last year – with torque growing 15 lb-ft to 325. In a world where Cadillac produces a 556 horsepower station wagon, 400 horsepower might not seem like a lot, but the 911 Carrera S makes good use of what it has.

Porsche added about 128 lbs. of content to the 991, but also managed to take out 216 lbs., resulting in a net reduction of 88 lbs. That weight loss can not only be felt in the corners, but also in a straight line.

Mash the throttle from a standstill and PDK-equipped versions of the 911 Carrera S can reach 60 mph in as little as 4.1 seconds (add 0.2 for manual cars). Give it enough room and the Carrera S will eventually hit 189 mph.

But perhaps the Carrera S’ most impressive performance stat is that it lapped the Nurburgring in 7 minutes, 40 seconds – matching the time of the outgoing 997 Turbo.

And, although we didn’t quite reach those kind of upper limits, we can report that the 991 is (thankfully) still a 911. The 991 feels perfectly balanced and the switch from conventional power steering to a new electric unit hasn’t affected the car’s steering feel. In fact, we couldn’t tell a difference at all.

The 991 is fantastic to drive on-track – especially with the Sport Plus mode engaged, allowing for some tail-out fun – but we found the car to be equally at home on the winding backroads of Southern California. The Carrera S’ suspension is surprisingly supple over most road imperfections and Porsche’s PDK transmission is near-perfect. Shifts are lightning fast, but we were most impressed with its low-speed operation. While most dual-clutch units are clunky and awkward during the transition from idle to load, the seven-speed PDK felt much like a conventional slush box. Other automakers should definitely take note.

And speaking of notes, the 991 belts out one of the best soundtracks we have ever heard. Throaty and growly at low speeds, the 3.8 turns into a screamer above 4,000 rpm – think Formula 1 car. Porsche has even fitted the newest 911 with an exhaust button to funnel more of that sound into the car’s cabin.

And you’ll likely need that button on a long road trip as the 991′s massive tires – 245/20 up front and 295/20 out back – generate quite a lot of road noise. We found the noise to be an equal trade off for road grip, but some might not agree.

Leftlane’s bottom line
Porsche has done it again, creating yet another 911 for the history books. Although the formula remains the same, Porsche has managed to vastly improve the 991 through a series of incremental changes, resulting in what could be the best 911 since the much-loved 993.

The 911 is no longer Porsche’s best-selling model, but the 991 present a strong argument for why it should be.
