Automobile Magazine compares the 2015 Mercedes-Benz C63 AMG and 2015 BMW M3, which are both benchmarks in their segments. Here is an excerpt from their review:
Both engines have musical talent, although the sound engineers at M and AMG alike have dialed in too much computer-generated background music. There’s fake heeling-and-toeing, fake blat-blat on overrun, fake upshift ka-chumm, fake idle-speed thud. For the AMG car, you can specify an even more hooliganesque triple-flap exhaust, which sounds positively puerile.
On Portuguese country roads that have not yet been resurfaced with European Union money, the M3 is not happy. Not happy at all. Its rear wheels scrabble about the poor pavement whenever we nail the accelerator, even when we’re already rolling at 130 mph. The Bimmer’s rigid chassis shines on the track and on smooth A-roads, but it backfires when the going gets rough.
The C-Class pulls out a small lead here, but it, too, has flaws. The low-speed ride is, for instance, disappointingly brittle, and body roll is occasionally an issue. And when it comes to crunch time, the C63 AMG will try to ever so slightly understeer out of trouble. Through the same series of corners taken at comparable velocity, the M3’s nose bites, turns in, and holds the line. And if all else fails, the M3 still has an old-fashioned hand brake to yank in the hairpins.
