[DETROIT] IT’S Official BMW M3 AND M4 Coupe is here!

It honestly feels like today is Christmas with so many teasers so many awesome cars coming out and today BMW just hit us with the big bang unveiling the 2015 BMW M3 Sedan and M4 Performance Coupe. The M4 and M3 will use a straight-six as reported earlier, which is good for 425 Horsepower 406 Pound-Feet of Torque with a 0-60 Time of 3.9 seconds and 4.1 seconds for the 7 Speed DCT manual gearbox.

BMW has stated that they managed to shave off around 176 pounds off the M4 from the pass E92 M3. Along with producing a more fuel efficient vehicle by shaving off nearly 25% of the outgoing M3 while adding 50% more unique parts. 

The new performance monster from BMW is featured with a Track specification and cooling system, A new lap time application(see below)

 These two monsters are expected to hit the showroom come summer 2014, and although pricing hasn’t been announced as yet, we advise that you all should get your pennies ready.

  • Front apron, smooth underbody and gurney spoiler at the rear of the M3 Sedan (or integrated spoiler lip at the rear of the BMW M4 Coupe) reduce lift by an equal degree at the front and rear axle.
  • Inflowing air through the engine oil cooler creates a Venturi effect, which reduces front axle lift and, in so doing, improves the steering.
