2nd Place: 2008 Mercedes-Benz C350 Sport
Cars of the three-pointed star built many moons ago are known for their hewn-from-steel character. It's been said that those days are gone, and that the modern Benz isn't built like it used to be.

We'd like to respectfully disagree. The automaker has fortified the current-generation C-Class with some of that Old World substance. From behind the wheel, the C350 feels reassuringly solid, from the thunk of the doors as they shut close to the chunky action of the shift lever on the center console. Yet this feel of mechanical gravitas doesn't come at the price of sheer weight, as the 3,621-pound Benz is 250 pounds lighter than the Audi A4.

This works to the Benz's advantage in straight-line acceleration, where the baby Benz just plain thrashes the A4. The 60-mph mark comes up in 6.3 seconds (6.0 seconds with 1 foot of rollout like on a drag strip), fully 0.6 second quicker than the A4. Similarly, the Benz sails through the quarter-mile in 14.5 seconds at 96.5 mph, a half-second quicker than the Audi.

It's mostly down to the weight difference, because the C350's 3.5-liter V6 puts out 268 horsepower and 258 pound-feet of torque, just shading the Audi's 3.2-liter V6 by 3 hp and 15 lb-ft.

Another key factor in the C350's eager performance and refined disposition is its seven-speed automatic, which neatly covers a wider spread of gearing than the Audi's six-speed and also changes cogs with eel-in-Crisco slickness. Shifts are nearly imperceptible, and when you floor the throttle, the car gathers velocity as seamlessly as if it were powered by an electric motor.

It might be that Mercedes has gone a little too far with the sense of substance in its character, however, because this car always feels a little inert compared to the A4. At casual speeds, the C350's tautly damped wheel action hints at a dynamic treat that doesn't fully materialize once you pick up the pace.

When the roads go all noodly, the Benz is Julie Andrews — it demonstrates impeccably good manners but just doesn't quicken your pulse. So it was no surprise when the C350 posted 65.8 mph in the slalom, trailing the A4's performance by more than 4 mph. The Benz's suspension damping is firm and well-controlled, while ultimate grip of 0.84g on our skid pad is just a tad less than the Audi's result.

Functionally, the 2008 Mercedes-Benz C350 doesn't miss a beat, particularly in the utility of its intuitive multimedia interface, which is the polar opposite of the clunky interface found in previous-generation Benzes. At the same time, the interior of the C-Class is slightly design-y yet cold and unfriendly, as if Sister Mary Margaret were lecturing you about ergonomics.

None of the C's shortcomings are terminal. On the contrary, we reckon the inclusion of the European-market sport package and some of the Euro interior features would do a lot to wake up the 2008 Mercedes-Benz C350.

1st Place: 2009 Audi A4 3.2 Quattro
Let's get this part out of the way — despite the additional traction provided by its all-wheel-drive system, the 3,870-pound Audi A4 is just too portly to keep pace with the C350 in the stoplight grand prix. Acceleration to 60 mph consumes 6.9 seconds (6.6 seconds with 1 foot of rollout like on a drag strip), and the A4 clicks the quarter-mile in 15 seconds flat at 94.7 mph. Audi's 3.2-liter direct-injected V6 is smooth and emits a pleasantly distinctive warble, but it will take more than its 265 hp and 243 lb-ft of torque to out-drag the leaner C350.

Aside from that, the new 2009 Audi A4 is a serious contender. Like the automotive equivalent of actor Jack Black, the A4 executes its dynamic moves with a grace that is at odds with what the scales suggest should be possible. Much of this can be attributed to the talents of its structurally rigid new chassis rather than what's under the hood.

Thanks to multiple personalities, the A4 also gains an edge in our scoring system. Audi Drive Select is similar in concept to BMW's M Drive in that it provides different calibrations — called Dynamic and Comfort modes — for throttle response, damper action, shift speed and both steering ratio and level of assist. (Fans of Mr. Potato Head will appreciate the ability of Individual mode to mix and match all these parameters.)

Click Dynamic mode and the whole car instantly snaps to attention, providing the A4 with a selection of direct, quick responses that the C350 can't deliver. There's a lot of body control in this mode, plus the new A4's improved weight distribution keeps the outside front tire from being abused as much as before.

On the road, the Audi's tires give up long before the chassis loses its poise, so driving at the limit of adhesion is ridiculously easy. Oversteer remains off the menu, though this new A4's handling balance is more neutral than ever before, so you can toss it into the corners — a dynamic that contributes to its solid 70 mph in the slalom.

Braking also proves more effective in the A4 than in the Benz. The subtleties of pedal effort and modulation are similar between the two cars, yet the A4 simply stops better, requiring just 107 feet to stop from 60 mph. This result is 11 feet shorter than the Benz's best effort.

Nitpicks? The A4's steering offers precision that the languid steering ratio in the C350 can't match, but the weighting and feel of the Audi's variable-ratio rack is more artificial than we'd prefer. And downshifts from the six-speed transmission are occasionally on the lurchy side.

The A4's interior has a much richer appearance than the C350's functionally sound but visually ascetic surroundings. And the Audi offers way more equipment, which is crucial in our scoring. In addition to the aforementioned multimode dampers and all-wheel drive, the A4 offers a back-up camera and parking proximity sensors, shift paddles on the steering wheel, adaptive cruise control and a lane departure warning system. None of these features are offered on the Benz.

Honestly, I didn't know that the Benz was lacking these features? I thought the C350 Sport had the shift paddles and such? May be I'm mistaken. But honestly though, there is something about the look of the Benz that makes the A4 look way to feminine.
 
C-class looks so much better but the A4 offer a great value. You get a lot of car for less money.
 
I hate tests where a car wins over the other because the standard equipment is better, and the car becomes cheaper because of that.
I sometimes think that when a car needs all these extra's, they're hiding the fact that the car itself is a bit less good.

Either way, C for me me. Looks stunning with sport pack and in red.
I always think the A4 somehow looks stoned :cool: . The Cis more agressive/angry
 
So they praise the A4 for offering AWD as standard and at the same time complain that the C350 doesn't have AWD? Why didn't they use a C350 4Matic then? :t-crazy2:

I have no problems with the A4 winning this comparison but little stupid comments like the AWD issue annoy the hell out of me.

Also, paddle shifters are available for the C350 if you order the sport package, I believe. But at the same time, these are hardly worth getting since manually shifting on the 7Gtronic isn't as hard as some people think it is - and I seriously doubt that your average C350 buyer is the type of person who will do some serious track driving with it (and that goes for the A4 compared here as well).
 
Well there is no C350 4Matic in the U.S. so...... I knew the outcome of this test when I saw the headline. My main problem with the C350 is that same old 268hp engine, not all those features. I can still park a car without a backup camera.

Apparently it is still faster than the Audi A4 and Cadillac CTS with the "old" 268-hp engine. The 7Gtronic helps a lot, like they said in the article (and less weight). ;)

But if you add BMW 335i to the comparison, its a lot slower. I'm still waiting for MB to offer a +300hp C-class. I have no idea why its taking so long :t-hands:
 
In Europe the engine has 292 hp, only the 335 is more powefull. But I am with Just_Me, Mercedes must incorporate the 315 hp 350 engine featured on the SL to the rest of the line up (C,E, S CLS, CLE).

I wonder when the hell are they going to make that.

That's the '350 CGI engine that has 292-horsepower. The regular '350 has 272-horsepower. In the refreshed SL and SLK models the '350 has over 300-horsepower. Why this engine is not yet in the C-Class is beyond me. :usa7uh:

Not to be bias but I totally agree with that, great point!
 
I think standard equipment is relevant. One thing I hate about german cars are that you have to pay a lot of cash to get the equipment you want. Japanese carmakers are much better, they come with much more standard equipment than the germans does.
This is something both BMW and Mercedes can learn from other carmakers. Offer a better value and more standard equipment. Unfortuanly its the extra options the german carmakers earn their money on.

Well I think it has to do more with making a name for yourself first which means you have to suck up to the customers more at the beginning until you get the reputation going which is exactly what Lexus is trying to do in Europe right now and have successfully done so in USA.
 
Both are amazing car. The C is the most beautiful Benz out there right now. Actually I would have a hard time choosing between these two. If it would be A5/S5, I'd take one over these any day. The A4 has somthing that doesn't say "wow" for me...

True, but I'm always thinking 300hp, that is the standard in this class now.

Mercedes' V6s are all over the map, 268hp, 292hp, 305hp, 315hp, etc. Ridiculous IMO.

I get why the SLK350 version hasn't been put into the C-Class, its a higher revving unit, which MB might not feel is right for a sedan. Just a guess.

Not sure how the SL350's version arrives at its 315hp.


What is needed is a DI, 320hp version for everything wearing a "350" badge, IMO.

^^honestly though, as much as most of us would agree that the C350 should be over 300hp mark, it still isn't an issue for the average car buyer. Besides a car guy, I don't think the average person looking at the C will be like "What? Not 300 or more hp? I'm leaving right now!" Not going to happen. Sure, the C will get the new engines after the FL, but besides us, it's not really necessary.
