Ahead of the North American International Auto Show in Detroit next month, BMW has revealed its new 2015 M3 sedan and M4 coupe and they are amazing! One of the biggest changes in the Ms is actually a downshift—not in power, but in weight and engine size.
It seems BMW may be channeling the spirit of the original 1988 M3. Then, when it was first introduced, the M3 only had a 4-cylinder engine. Why, you might ask, because it weighed less and that made it faster. BMW used the same principle in these new models. The engine has been dialed back down to six-cylinders and the Ms have lost a handful of pounds in their curb weight.
Engineers used lightweight materials, such as carbon fiber and aluminum to replace or reinforce certain parts on the body. The roof panel, for example, is made with aluminum, which not only makes it weigh less, but also lowers the car’s center of gravity and gives it better handling.
And, in case you’re worried about a smaller engine being less powerful, it’s not. The 3.0-liter turbocharged inline-six puts out 425 horsepower—5 more than the previous V8. And, the torque is even more impressive. Now we get 406 lb-ft compared to the much smaller 295 lb-ft from the V8. So much more power and it weighs 22 pounds less.
We’re so excited about the new 2015 BMW M3 and M4. We can’t wait to learn even more about them next month at the Detroit Auto Show.
