Three V6 engines see duty in the Mercedes C-Class lineup. The C230 has a 2.5-liter V6 that provides 201 horsepower and 181 pound-feet of torque. Standard safety features include antilock disc brakes, stability control and six airbags that include front-seat side airbags and full-length side curtain airbags. Rear-seat side airbags and the TeleAid emergency call system are optional. In NHTSA crash tests, the 2007 Mercedes-Benz C-Class scored four out of five stars for driver and front-passenger protection in frontal impacts, and five stars for front and rear side-impact protection. The IIHS gave the C-Class a 'Good' rating (its highest) for the car's performance in the 40-mph frontal-offset crash test. The C-Class earned an 'Acceptable' rating (second-highest) in IIHS side-impact testing. As one would expect, the 2007 Mercedes-Benz C-Class is a comfortable car that excels at pampering its occupants. The 3.5-liter V6 is by far the best engine of the lineup, but either of the smaller engines will likely be adequate, especially if you're restricted by budget. In terms of handling ability, Sport models don't feel as light on their feet as other top sport sedans. But they turn in aggressively and offer decent grip. Body roll is reasonably well controlled, but driving enthusiasts will likely wish for even firmer damping and more steering feedback.
