The C-Class may be a compact sedan but it's also a solid, agile, quiet, comfortable and credible luxury car. We tested the base C250, powered by the exceptionally smooth, 201-hp, turbocharged four-cylinder engine Mercedes introduced for 2012. It serves up ample power, but its 24 mpg is not exactly stellar.
