The fabled BMW M3 returns for 2015 after a brief hiatus. This aggressive-looking, track-tuned compact luxury sedan comes with a new turbocharged 6-cylinder engine that promises exemplary power. As always, expect stellar handling and agreeable ride, along with a slew of high-tech, performance-oriented components and technologies. It is, after all, the so-called "Ultimate Driving Machine."
Put the central masses -- the engine, occupants and fuel -- in the middle of a car, and you lay the foundation for a machine that's more responsive, agile, and stable at high speeds, than one with the heavy stuff concentrated at either end.
