The all new BMW M3 sedan and M4 Coupe are set to let your pulses racing

After a long period of anticipation, BMW has finally, officially unveiled the 2015 M3 Sedan and M4 Coupe sporting the company’s new nomenclature for the first time. A few press shots were leaked over the internet briefly before the official unveiling. And now that it’s out, we can say the two high-performance versions of the new 3 Series and 4 Series that launched this year are drop dead gorgeous. But looks and the strange nomenclature aside, the specifications under the hood are intriguing and might irk a few BMW M3 fans. All those who’re familiar with the history of M badged cars know that they rarely have remained the same over the four previous generations. BMW has constantly experimented with newer configurations to get the best performance figures and in the latest fifth generation, the M3 and M4 have lost a pair of cylinders. So that means no more screaming V8s.

The naturally aspirated V8 has been swapped for a twin-turbocharged 3.0 liter inline-six engine. The improvement in the performance figures is enough to offset the loss of the naturally aspirated screamer. The new turbocharged inline engine is a good 22 pounds lighter than the V8 in the older generation of M3 and is extremely rev-friendly. The 3 liter inline-six makes 425 turbocharged horsepower which is marginally better than the 4 liter V8, but what’s more interesting is that the power evenly spread over a broad rev range of 5,500rpm to 7,300rpm – which guarantees linear power delivery. The engine produces a peak torque of 406 pound-feet that starts at 1850 rpm and continues all the way till 5,500rpm – a huge improvement from the previous engine. The main reason to put a turbocharged engine is to get good fuel economy and that’s where the new M3 sedan and M4 coupe shines. BMW claims, the fifth generation M3 is 25 percent more economical than the previous version. Both are almost 80kgs (176 pounds) lighter than their predecessors and will do 0-62mph in 4.3 seconds (4.1s with the DCT gearbox) and hit a top speed of 155mph which is electronically limited.

Coming to the aesthetics, on the outside, though the two performance machines look similar to their foundation 3 and 4 series cars, but there is enough M-badged treatment for us to fall in love. They both have a beautifully chiseled nose with the front apron and wide air intakes designed to add downforce that’ll keep it stable at high speeds. Both cars will leave the factory on low weight 18-inch forged wheels with mixed-size tires but 19-inch wheels and tires are available as an option. On the inside, the double-spoke M Sport leather steering wheel comes as standard, as are bucket-style M sports seats and the BMW Individual roof liner in Anthracite. The M logo, chrome trim and color contrast stitching are enough to give the cabin a racing ambience. The BMW M3 and M4 will make their public debut at the next month’s Detroit Motor show and will go on sale by summer next year.
