2017 BMW 3-Series vs. Its Competition

2017 BMW M3
Aaron Cole Aaron Cole Managing Editor

The BMW M3 has held the crown of ultimate sports sedan for some time, but its lead is slipping.

The Mercedes-Benz C63 AMG has long been a natural rival, but lacked the BMW's taut controls in favor of brutal—sometimes savage—power.

The Audi S4 is a road-holding machine, and we're eager to see what Ingolstadt has in store for 2017, so stay tuned.

The Cadillac ATS-V is a sleeper pick here, and its 3.6-liter turbocharged V-6 is a force of nature, but its ropy manual transmission and interior spoil the fun.

Porsche's 718 twins are performance rivals, but neither can carry your in-laws.

(We didn't say that was a bad thing.)

Quick Specs
The 2017 BMW M3 is a track-ready sports sedan with an unblemished pedigree that announces to the world: "Ask me what DTM means."
The 2017 Mercedes-Benz C-Class adds to the impressive roster with a convertible version this year and a newly minted AMG C43 version. Bavaria is even better now.
The 2017 Porsche 718 Boxster and Cayman remains some of our favorite performance cars; they're thrilling to drive, and in base form they're exceptional sports car value, too.
