The BMW M4 series is still relatively new which is the reason why it might not sound familiar. If you are considering a new BMW, the BMW M4 coupe should be one of the options that you look at. The recipe for the BMW M4 coupe is the same as the original M3, a powerful engine, drive wheels at the back and a gearbox in the middle.The MPG And CO2The BMW M4 coupe offers a 3.0-liter turbocharged petrol engine with 6 cylinders. This is different from the previous model which offered a 4.0-liter V8 engine. While the engine is smaller, the turbocharged nature ensures that fuel efficiency is improved. Of course, it is important to note that the engine is not as economical as a 1 series, but will be more efficient than rivals in the same class.When it comes to official fuel efficiency figures, the M4 offers 32.1mpg. The CO2 emissions for the car come in at 204g/km. It is important that you consider these figures because they will affect the tax and insurance that you face with the vehicle. The overall running costs will also be impacted by the fuel efficiency.The Drive And PerformanceThe engine in the car was specifically built for the M division cars from BMW and will provide you with incredible performance. The M4 coupe is able to reach 62mph in just 4.1 seconds thanks to the 425bhp that is on offer. The top speed is electronically limited to 155mph which is more than enough for any user.The engine performance is only part of the story when it comes to the drive of the vehicle. The BMW M4 coupe is lighter than the older version and there are a number of adjustments which have been made to the steering, engine response, and suspension. These adjustments ensure that the car can be transformed from the motorway cruiser to the bare-knuckle sports car with a few buttons.If you are going to get an M4 coupe with an automatic gearbox, you will be able to adjust the speed of the gearshifts. There is also a launch-control feature which will help you rocket away from traffic lights. When you use this feature, you will be able to pull away 2 tenths of a second faster.The Interior And ComfortThe M4 coupe is a comfortable cruiser because of the adjustment to the suspension. The sportier suspension along with the stiffer body results in a firmer ride that is surprisingly soft. The only time you will notice the sporting edge of the car is when you bit sudden bumps or ruts in the road.One of the issues that you might have when it comes to comfort is the noise the high-performance tires create. When you hit certain surfaces, the sound could be loud enough to drown out the stereo. Additionally, some of the noise from the engine does come through the speakers, but it can sound artificial and many people find that after a while it gets on their nerves.
