You may wonder how much we still a surprise call, but BMW has in the run-up to the official unveiling of the M3 and M4 coupe the facts and figures released.
Dr Friedrich Nitschke, President of BMW M GmbH – late-after the posts from earlier this week– in an official press release, the following issues are know. First, what, blah, blah, blah, blah about how the new turbo engine the character of an N/A block combines with the advantages of a turboblok. The new high-revving up (7500 rpm is the max), six-in-line S55B30 block 430 horsepower and deliver 500 Nm of torque thanks to BMW’s M TwinPower Turbo technology. Especially that torque is an improvement compared to the 400 Nm that the e92 M3 standard resulted. Together with a weight under 1,500 kilograms, this must be block to make sure that 25% less fuel is consumed. In your dreams.
The good news: by default, send the BMW M4 and M3 their ability through a manual zesbak (!) to the rear wheels. No eco-bastard-muesli machine so, just stir with the poker. This tray is 12 kilograms lighter than its predecessor and provides the tussengas at the back, something previously only in the DCT so it was. Of course, old people with gray hair that launchcontrol important to find just a M Double Clutch Transmission with DriveLogic order. This tray features seven oppose. A CFRP (carbon fiber with plastic, you know) drive shaft delivers power ultimately to the differential lock but is thanks to the use of this material is 40% lighter.
About the diff: there is a new, continuously variable differential mounted that continuous the correct amount of lock calculates for your gumbehoefte. Therefore, there is more traction, more configurability of the behavior of the car in turns and it minimizes understeer at the uitaccelereren of curves. In M Dynamic mode locks the differential before so there to your heart’s content gedrift while DSC an eye in the sail. Unless you completely turned off of course…
And then the kicker: electric power steering. Annoying enough this is a trend that all modern cars seem to have undergone but with the 3 Series BMW has already shown that they have an excellent feel to create. However, you would in an M3 is just that little bit of extra feedback in your hands want to feel, so let’s hope that the magicians of M GmbH still have some of their magic on the steering have to know to throw.
In appearance there is a lot of defined but thanks to those annoying camouflagestickers remains difficult to see the final picture to see. However, it is clear that there is a CFRP roof on the car. This gives 5 (the M3 sedan) and 6 (on the coupé) kilo weight saving. The M4 gets a “kerbweight” of less than 1500 kilograms, a saving of 80 kilograms compared to a “similar equipped” e92 M3 coupe, according to BMW.
Accelleratiecijfers, top speeds and other juicy info is even retained, Timo Glock and Bruno Spengler are apparently still too busy with laps on the Nürburgring hunting to which these figures are final.
