At the 2014 Detroit Auto Show, BMWLOG sat down with Dr. Friedrich Nitschke, M CEO, Albert Biermann, Head of M Engineering, and Carsten Pries, Director of M Product.

The 45 minutes long discussion touched on subjects like electric power steering system (EPS), Automatic rev matching on the manual transmission, Nurburgring times and more.

Manual Transmission

Manual transmission is based on the BMW 1M and it’s 12 kg lighter than the gearbox found in previous E90 / E92 M3. It uses a twin blade clutch and upgraded oil system. If one orders the manual transmission instead of dual clutch gearbox, it will also save 25 kg (55 lbs). The new feature on the manual transmission, automatic rev matching, is only enabled in Sport and Comfort driving mode, but disabled in Sport+ mode.

Engine

For the S55 engine, M engineers have developed an extremely effective cooling system. Alongside the two ultra-dynamic turbocharger units, the air intake system of the six-cylinder engine also includes an indirect intercooler to cool the intake air. The engine crankshaft is about 3kg lighter than the N55 engine and at the same time is 20 percent stiffer. Crankcase housing is 2.8kg lighter. It also uses an aluminum alloy coated with steel plasma.

Electric power steering system (EPS)

BMW says the electric power steering system (EPS) in the BMW M3 / M4 is the best on the market today. The M folks say they aimed to improve the steering in the previous generation M3.

Carbon Ceramic Brakes

No pricing yet, but they certainly help with weight savings, between 6 and 7 kilograms. It has 6 piston front and 4 piston rear calipers.

Weight Savings

  • Rear seats are 5 kg lighter than regular 3 or 4 Series seats
  • Trunk lid / gurney remove 5 kgs
  • Standard carbon fiber roof for both cars

xDrive in future M3 / M4 / M5 / M6 models

The M engineers say since the focus of their recent efforts were around weight savings, going to an xDrive system for future models will be a setback. They basically said that adding an extra 70-80 kg will defeat the purpose.

Competition Package

Nothing to announce at the moment but we have heard that a pack similar to the M5/M6 Competition Package would follow.

Here is the roundtable discussion with journalists:

    Is that a manual or dct car that is 10 seconds faster was the time set on standard tyres or specially prepared ones does the m3 and m4 have the same ring times which is faster and finally what was the ring time on a fully loaded m3 and m4 as this would put the time in perspective against a E92 m3.

      Not sure they ever release these figures. Independent tests will show that.

    Dang there goes our dreams of ever owning a XD M car. The Only M car that features Awd system is the x5 m but thats not even a car. Its an suv which weighs in about 5,368 lbs, so why have a X M Model if your not planning on doing the same to the other base models. Saving weight is a poor excuse, even if it adds an extra 200lbs. You need to find other ways of shaving that weight off. Maybe carbon fiber the hood, fenders, or even the trunk. It should go down to at lease an extra 100lbs, and give it more room to fit the Xdrive system. People would love the feel of a BMW Awd monster that puts the power to all four wheels, with control rather than just the typical 2. People love options! It may even Dominate Mercedes 4matic and Audi’s Quattro awd systems. Let it remind people that BMW is the Ultimate Driving Machine!
