2015 BMW M3 vs. Its Competition

2015 BMW M3
Nelson Ireson Nelson Ireson Senior Editor

There aren't many other choices when it comes to high-performance luxury sedans in the BMW M3's size class, but the Mercedes-Benz C63 AMG could be a solid alternative.

With a potent engine and track-bred styling, the new C63 is as head-turning and as smile-inducing as the last M3.

Audi's S4 is not quite as sharply tuned as the M3 or C63 AMG, or even Audi's own RS5, but if you don't require as much spice with your sugar, the S4's clean aesthetics and refined interior may be more appealing to you.

For the way the M3 is used, we'd suggest some coupe alternatives, too--namely the outgoing Cadillac CTS-V two-door, a car capable of stunning acceleration, and the Porsche Cayman/Boxster duo, our choice when brilliant handling is the first and only requirement.

Quick Specs
Minus the V-8 and almost a couple hundred pounds, the 2015 BMW M3 is the best performer yet to wear the vaunted badge.
The 2015 Audi A4 and S4 sedans are tech-laden, trim, handsome alternatives to the other expected German cars, as well as one very good American one.
Forget this model's recent past; the 2015 Mercedes-Benz C-Class takes a half-step up in size and a full step ahead of its peer set in sophistication -- and it's now one very charming luxury car.
The 2015 Porsche Boxster is a relative performance bargain, combining everyday usability with a balanced chassis and sweet engines.
The 2015 Porsche Cayman remains a focused 911 alternative, at an easier-to-swallow price.
