- The developers of the BMW M3 and M4 have the floor. No frills; just information - first-hand from those who know best. In Episode 16, Dominik talks about the rear axle transmission of the new M vehicles.
BMW M3 Competition / BMW M4 Competition:
Fuel consumption in l/100 km (combined): 10.2. CO2 emissions in g/km (combined): 234.
BMW M3 / BMW M4::
Fuel consumption in l/100 km (combined): 10.8. CO2 emissions in g/km (combined): 248.
The values of fuel consumptions, CO2 emissions and energy consumptions shown were determined according to the European Regulation (EC) 715/2007 in the version applicable at the time of type approval.
The figures refer to a vehicle with basic configuration in Germany and the range shown considers optional equipment and the different size of wheels and tires available on the selected model. The values of the vehicles are already based on the new WLTP regulation and are translated back into NEDC-equivalent values in order to ensure the comparison between the vehicles. [With respect to these vehicles, for vehicle related taxes or other duties based (at least inter alia) on CO2-emissions the CO2 values may differ to the values stated here.] The CO2 efficiency specifications are determined according to Directive 1999/94/EC and the European Regulation in its current version applicable. The values shown are based on the fuel consumption, CO2 values and energy consumptions according to the NEDC cycle for the classification.
For more information on the WLTP and NEDC test procedures, see www.bmw.com/en/innovation/wlt....
Further information on official fuel consumption figures and specific CO2 emission values of new passenger cars is included in the following guideline: 'Leitfaden über den Kraftstoffverbrauch, die CO2-Emissionen und den Stromverbrauch neuer Personenkraftwagen' (Guide to the fuel economy, CO2 emissions and electric power consumption of new passenger cars), which can be obtained free of charge from all dealerships, from Deutsche Automobil Treuhand GmbH (DAT), Hellmuth-Hirth-Str. 1, 73760 Ostfildern-Scharnhausen and at www.dat.de/co2.

this is gold content
Thank you for doing this. We petrolhead enjoy them!
Great video but I didn’t understand why the larger diameter of one of the driveshafts improved traction, could you explain that a bit more?
The two rear output shafts are designed with different stiffness resulting in an optimized harmonic behaviour of both rear wheels and thereby increasing traction.
@@BMWM Thank you!
Usually this also helps stop wheel hop. Identical shafts would, like they say be a bad harmonic behavior

Danke 😊
This is why my car drifts so well
Great video! Any video available on the m performance lsd differential for the m140i for example?
Ok very good thanks for sharing, but I have a question. How often do I have to change these discs in the differential and the Cost thank you!
Sublime !
Does this diff use the rear brakes to control wheel spin even with dsc?
On track the rear brakes are wearing heavily - faster than fronts. The e90 was known to do this. Also would hot rear brakes due to excessive traction intervention that throws code 48087D cause engine speed reduction?
Cool
Did f80 also have different diameter of drive shaft ?
How can the different diameters of the output shafts result in a “much more harmonic acceleration behavior” in the wet condition..?
Subframe is mounted rigidly which means a lot of welding once it becomes a "classic" like e46 m3
😍
BMW ou rien Mes locooooossssss
Hallo Dominik, do you consider consider yourself the luckiest G80 member because you work at the back, away from the front 🐽 snout?

You: "fIrSt"
Mate, you're not first by a long shot!
I guess I'm fourth then?
@@Anriandor no
Dub really destroy anything
Really cool info to share, but still not the proper video format, really not tv friend, and don't bmw engineers speak english as well? Bit surprise.. ;-)
