Five-Point Inspection: 2015 Mercedes-Benz C400 4Matic

4. Sizing it up

The wheelbase is three inches longer and 1.6 inches wider to offer more rear seat legroom and headroom, which is important because the C-Class doesn’t represent an entry point to Mercedes ownership in the U.S. anymore.

Trunk space is up to 17 cubic feet (37 percent more than before) as well. The new all-wheel drive V6 model is lighter than the model it is most comparable to, but only by 44 lbs although the company says the new model is up to 220 lbs lighter in certain configurations.

The fuel tank can hold up to 18 gallons, which is slightly larger than the old model. Combined with a more efficient powertrain and lower curb weight, the W205 should offer improved driving range as well.
