The Good The 2010 Mercedes-Benz C350's seven-speed transmission means decent freeway mileage, and a button toggles it between Comfort and Sport modes. A good navigation and audio system is available.

The Bad The optional iPod integration kit, when the navigation option is not chosen, has a terrible interface. The engine in the C350 doesn't provide a huge advantage over that of the C300.

The Bottom Line The 2010 Mercedes-Benz C350 is a comfortable driver with some sport aspirations, and cabin tech that can be decent or very bad, depending on the options.

The Mercedes-Benz C-class, the lowest-end Mercedes-Benz sold in the U.S., underwent an upgrade in 2008 that modernized the car considerably, making it an excellent value in a semi-sporty small luxury sedan. We earlier reviewed, and praised, the C300 Sport and the C63 AMG . This is the first time we've seen the 2010 Mercedes-Benz C350.

But the C350 sent to us turned out to be an example of how not to option up a C-class. First of all, the need for the car's 3.5-liter V-6 seemed questionable, as the 3-liter V-6 in the C300 does a perfectly good job. Second, our car lacked the navigation system option, saddling it with what is probably the worst iPod integration we've seen. The car was equipped with an 18-inch AMG wheel package, money which could have been much better spent making the cabin electronics useful.

C350 versus C300
According to Mercedes-Benz specifications, the C350 gets you to 60 mph in 6.1 seconds, exactly 1 second faster than the C300. The 3.5-liter V-6 in the C350 produces 268 horsepower and 258 pound-feet of torque compared with the C300's 228 horsepower and 221 pound-feet of torque.

The seven-speed automatic transmission goes from Comfort to Sport mode at the push of a button.

Obviously, the C350 goes faster than the C300, but not by much. The sensation of acceleration is even less different, as the only transmission available for the C350 is a seven-speed automatic. Although Mercedes-Benz has done an excellent job of refining automatic transmissions to give a near-manual transmission feel, it still masks the engine performance behind torque converter softness.

The C300 can be had with that seven-speed automatic or a six-speed manual, the latter being more of a driving enthusiast's choice. In the C350, a button near the shifter toggles the mapping between Comfort and Sport settings, making the gear changes more aggressive. You can also manually change gears by moving the shifter from side-to-side, producing reasonably quick shifts. But we didn't find a huge performance gap between the C300 and C350.

3.5-liters of V-6 offers too little of an advantage over the C300's 3-liters.

Both C-class models use the same suspension, a four-wheel independent setup with stabilizer bars front and rear along with antidive control. In either model, it does a wonderful job of keeping the car composed during hard cornering. The 37 extra pound-feet of torque should make a difference accelerating out of a turn, but we didn't feel the C350 had a substantial edge.
