This competitive sports sedan is enjoyable to drive and has a beautifully finished interior. The base C300 uses a 2.0-liter turbo four-cylinder, which returned a respectable 26 mpg overall in our AWD version. The C has quick reflexes, with prompt steering response and a comfortable ride. Inside, you'll find an upscale and snazzy cabin with a high-quality feel, but the complex infotainment system takes time to master. Semi-autonomous highway steering is optional, and autonomous braking is standard. The rip-roaring C63 AMG gets a 469-hp twin-turbo V8 in standard form or 503-hp in the S version. Additional variants include a C350e plug-in hybrid, C300d diesel, and C43 AMG with a 3.0-liter turbo V6. Reliability has been below average. A new coupe version is available for 2017.
Alert
This vehicle can be outfitted with a semi-autonomous driving package. Consumer Reports believes automakers should take stronger steps to ensure that vehicles with those systems are designed, deployed, and marketed safely. Please heed all warnings, and keep your hands on the wheel.

Lows

  • Gets rather expensive
  • Some commonly expected features, like phone voice commands, are not standard

Best Version to Get

Despite only having four cylinders, the C300 provides relatively swift acceleration and likeable levels of refinement. Sure, the available V6 engine in the C400 packs an even more powerful punch and is smoother than the four-cylinder, but we'd stick to the lower-numbered model. Most C-Cla...
