Since the first BMW M3 in 1988 the M series has been something special for BMW and, as much as it has become a matter of prestige, it is also a burden due to the fact that the cars with M label are expected to be special. This is why big changes are as dangerous as they are welcome.

Launching the M4 might be even more dangerous. It is a new name and a new car, albeit based on the BMW M3 coupe whose heritage it is supposed to continue.

Just how good these are we’ll have to see in 2015 but, based on the numbers and pictures, they should both be worthy successors.

When we talk about the design, we have to say that, now that it is here, we really do see why the BMW M4 was necessary. It is a wonderfully aggressive coupe with smooth lines and standard 18-inch wheels. The shape was dedicated to superb aerodynamics, but you will not see this. The front apron directs air around the car and massive air intakes take it in to create respectable downforce at the front as well as to cool down the components.

At the back, the rear lip spoiler creates the same amount of downforce. Rear wheel arches are wider due to the fact that they needed to fit suitable wheels and tires, but, rather than standing out from the rest of the design, they complement it and add to the great looks. The design was the main reason why the M3 and M4 needed to be separated. The M3 is a full bodied sedan that includes all the best of the M4’s design features while offering more practical four-door setup.

When it comes to driving, you will be pleased to know that tuning down to six cylinders actually delivered more power and that the 3l twin-turbocharged engine now produces 425hp and 406 lbs/ft of torque. There are two transmission options available. The M-DCT dual clutch option gets you to 60mph in 3.9 seconds, while the manual six-speed option does this in 0.2 seconds slower, but it still packs rev-matching automatic throttle blipping.

Just how great the engineering is done you can see from the fact that peak power is available in a vast range from 5,500-7,300 rpm while the peak torque is at early 1,800 rpm, and stays flat through to 5,500rpm. Add to this the aluminum suspension that is bolted directly to the chassis so it reduces weight and increases steering precision and both the M3 and M4 should be extremely interesting to drive.

It might be good to know that there is a BMW M Laptimer app for smartphones that connects to the on board computer and records speed, revs, steering angle, consumption and longitudinal and lateral acceleration. watch the video below
