The BMW 3 Series has long been regarded as the benchmark compact sport coupe, sedan and convertible. Taking this already athletic vehicle to new heights is the M version, known as the BMW M3. In the Bimmer world, the letter M stands for the company's Motorsports performance division. These fun-loving engineers tweak a given BMW model's engine for more output, upgrade the suspension for even more agile handling and add sporty exterior and interior design elements.

Throughout its two decades on the U.S. market, the BMW M3 has been a favorite of enthusiasts looking for sports-car performance and handling from a true four-place car. Although content to smoothly burble around while doing daily driver duty, the M3 transforms into a back-road burner when conditions allow and gives its pilot the opportunity to attack corners with precision and rocket out of them with gusto.

Current BMW M3

Based on the present-generation 3 Series, the current BMW M3 was introduced for 2008. There is only one trim level available among the coupe, sedan and hardtop convertible body styles. Each is powered by a 4.0-liter V8, good for 414 horsepower and 295 pound-feet of torque, which revs to a thrilling 8,400-rpm redline. A six-speed manual is the standard means of sending power to the rear wheels, and a seven-speed automated-clutch manual gearbox with paddle shifters is optional. M3s also get specific hardware upgrades such as more powerful brakes, stiffer suspension tuning and a specialized limited-slip rear differential.
