Over the last decade BMW has bolstered its product line, adding crossover SUVs while remaining true to its Ultimate Driving Machine motto. In the midst of the new-product onslaught, the 3 Series has remained its consistent sales leader and the standard of comparison in the sports sedan segment. The 3 Series Coupe is available with two different drivetrains, but both trim levels share distinctive looks and a demeanor that is even more sporting than the well-regarded sedans. The coupe is more than ready to battle prime foes like the Infiniti G35 and the Mercedes-Benz CLK 350. The complete generational changeover dramatically enhanced the sporting personality of the 3 Series Coupe. Its sharp styling is accompanied by available features like a twin-turbo drivetrain and all-wheel drive. For more new car reviews, interviews and automotive news visit kbb.com today.
