Sheesh, 4.5 stars for the 328i. Damn impressive.

I'm really happy to read that BMW sorted out their issues regarding the steering. Media haven't been satisfied with the steering on 5-series/6-series (which I agree with after my own personal experiences) so I'm happy it has finally been improved and works very good together with 3-series and 1-series.
AND it's a RHD!!! RSA/UK/Australia/Japan
Last year, the outgoing BMW 3 Series was still the eighth-best-selling car in Britain, despite launching seven years ago – proof that the UK is crucial to this model’s success. And to mark the arrival of the new 3 on UK roads, Auto Express has been given a world-exclusive first drive of the range-topping 335i.
This car is a sign of things to come: the next M3, due in 2013, will drop its V8 for a highly tuned six-cylinder and it’s likely to be loosely based on the 3.0-litre direct-injection turbo in the 335i.
The straight-six is also fitted to the new 535i, but in the smaller 3 Series – which weighs 25kg less than its predecessor – its performance is magnified. This car does 0-62mph in 5.5 seconds.
Throttle response is instant, with no hint of turbo lag, and the engine revs freely to 7,000rpm. On part throttle there’s a subtle growl from the exhausts, but press on and there’s a thrilling mechanical crescendo as it nears the red line.
Settle to motorway cruising speeds and you’ll notice how refinement has improved. Noise from the tyres and engine is brilliantly suppressed – only wind noise from the A-pillars and wing mirrors is audible. With 400Nm of torque, this car is also happy to crawl around like a diesel in a high gear at low speeds.
Ditch the manual box in favour of the more efficient eight-speed auto (a £1,660 option) and the 335i will return 39.2mpg – that’s 6.7mpg more than the old car. The new 328i, with its 2.0-litre turbo, is 4.9mpg more economical and only six tenths slower from 0-62mph (with a time of 6.1 seconds), but it can’t match the smoothness and sound of the six-cylinder.
In auto mode, the box blurs the ratios perfectly. Use the paddles and it shifts in the blink of an eye – there’s barely any interruption to the power delivery. We think this set-up makes the case for heavier twin-clutch boxes questionable.
Show the all-new 3 Series a B-road and it’s even better balanced than before. The steering weight doesn’t varymassively as you load up the front tyres, but it’s so direct you can place the car precisely and it always feels light on its feet. The facelifted Audi A4 seems slow-witted by comparison.
Agility hasn’t come at the price of comfort, either. All models get a switch that allows you to toggle through Eco Pro, Comfort, Sport and Sport+ modes, tailoring the throttle, steering and skid-control response. Our car had Adaptive M Sport suspension, too, and even on its firmest setting, this £750 option takes the edge off bumps and keeps body roll well in check.

BMW is making haste in relegating its normally aspirated inline-six to the dustbin of history. First it was the 528i and Z4 SDrive28i, and now the 2012 BMW 328i has made the transition to a 2.0-liter boosted and direct-injected four-pot known in BMWland as N20.
And it's not like this all-new 3 Series is a smaller car than its straight-six-havin' predecessor. In fact, the 2012 328i casts a larger shadow and weighs just a hair more than the outgoing car. Yet the N20 moves the 328i with ease, perhaps with more ease than its rated values of 240 horsepower and 255 lb-ft of torque suggest.
With that, off to MD Automotive's dyno rollers we go.
You'll notice that the devastatingly handsome speaker in the video said that the 2012 328i's factory rating is 245 horsepower. It is, if you believe the owner's manual, which is where I he found that number.
A brief conversation with BMW afterwards revealed that the numbers in the owner's manual are not correct and that the real rating is indeed 240 horsepower (and 255 lb-ft of torque).
According to our dyno testing, neither set of numbers are correct -- they're all conservative. See here:
That's 240 horsepower and 257 lb-ft of torque as measured at the wheels. It was dead-repeatable on the dyno, too, laying down the same power over nine consecutive pulls.
Like observed with the Z4, there's a dip in the 328i's torque curve at 5300 rpm, less pronounced in the 328i but still present. Also, that hole at 2300 rpm showed up in every pull and I even felt it on the road. It's so low in the rev range, though, that you really have to drive like a clown to elicit it.
And like always, our testing was on 91 octane "premium" fuel. Yes, that's the best we can get in California. Yes, it's lame.

Now, we've previously dynoed the N20-equipped Z4 SDrive28i, rated at a near-identical 240 horsepower and 260 lb-ft of torque. And we found it to be similarly stout, producing nearly as much power as measured at the wheels as is claimed at the flywheel.
The 328i eked out a thin whisker more urge across most of the rev range, but you can probably chalk the difference up to run-to-run and car-to-car (and day-to-day) variation:

Same roll-off of torque at 5000 rpm, same end to the festivities 7000 rpm. The N20 is not an engine that begs to live near the rev limit, but it does generate a fat slug of torque that makes daily driving easier.
And in the 328i, this power delivery makes sense. Less so in the Z4. Sports cars are not sedans, and the engine's character should reflect this.

Another thing you'll notice in the video -- power and torque gauges on the 328i's multimedia screen. I stumbled across the display while poking around iDrive between pulls.
The gauges are in metric, but when you convert the peak numbers, it says it produced 228 horsepower and 251 lb-ft of torque. Not too far off of what we measured at the wheels during that run, actually. The display is a gimmick, but at least it's a somewhat accurate one.
Anyway, yeah, the N20 continues to be strong. I don't think anyone's going to complain about that. The low-gain throttle pedal, maybe. But not the grunt it puts out.
According to the dyno run that you'll see after the break, the tradition continues with BMW's new twin-scroll turbocharged four-cylinder inline N20 engine that sees duty in the 2012 328i. The mill is rated at 240 horsepower and 255 pound-feet of torque, and on at least one Dynojet dyno, a stock 328i put down 226 horses and 230 lb-ft.
Assuming that around 15 per cent of power is lost to the various friction forces of the drivetrain, these results indicate that the engine is really spinning out 265 horsepower and 270 pound-feet of torque. Those are mighty impressive figures, and equal about 25 more horses than stock and at least 15 more lb-ft of torque. Suffice it to say, this engine is an extremely tempting proposition for future 3 Series owners.
