Right now, we’re still in the dark about a lot of the specs and features on the upcoming BMW M3. We know a bit, like the fact that it will be built on BMW’s new CLAR platform and that it will be lighter and more powerful than the outgoing car. However, there are still a lot of unknowns, such as powertrain, transmission and chassis tech. Though, we’re starting to hear some whispers, as information slowly begins trickling out ahead of its 2020 release.

One of the more interesting bits of info, according to Autocar, is that it will actually be lighter than the current BMW M3 CS. The M3 CS is the lightest, most dynamic and, plainly put, best version of the current BMW M3. The BMW M3 CS currently weighs in at 1585 kg (3,494 lbs), which isn’t exactly portly but isn’t exactly lightweight, either. So the fact that the next M3 will weigh less is encouraging.

Especially when considering that it will pack more technology and more power. We don’t have any word on its engine or specs but we do know that it will us a newly updated 3.0 liter twin-turbocharged I6 and make between 450 and 500 hp. There have been rumors that it will get the same water-injection technology that the M4 GTS uses, which could easily boost power output to around 500 hp. Though, that adds weight and complexity and, in our eyes at least, seems like an unnecessarily complicated way to make that sort of power. Audi currently can make that sort of power from a 2.9 liter twin-turbo V6, so there’s no reason BMW can’t match it on pure engine power alone.

There have also been rumors of some sort of electrification, with an electric motor being connected to the gearbox to add e-boost, which would reduce turbo lag and increase efficiency. If BMW does decide to enhance the engine in any way, this seems like a better idea than water-injection.

Autocar also claims that BMW is considering giving the next M3 rear-wheel steering, just like the new 5 Series. If that’s the case, it would not only be the only 3 Series to have such tech but the only car in its class as well. To be honest, it doesn’t seem like it makes much sense, as it would also add weight and the BMW M3 is already going to be small-ish and nimble.

As far as transmissions go, a six-speed manual will be available as-standard but some sort of automatic will also be an option. We don’t know yet whether or not it will be the brand’s seven-speed dual-clutch unit or an eight-speed ZF traditional automatic. The latter of which is used in the new BMW M5 but that was done more for torque and cost reasons. The BMW M3 won’t have as much torque as the M5 and can therefor use a dual-clutch. However, when it comes to cost, the ZF eight-speed is going to be the more economical choice for BMW.

While we won’t see the new BMW M3 on the road until 2020, we will likely find out what it’s all about by next year. Stay tuned.

    Should just drop the dual clutch from M cars and offer AWD through the range. Regular automatics have gotten good enough that it’s not needed and most buyers of M cars prefer the smoothness of regular automatics over the jerkyness of dual clutch cars at low speeds.

  2. Dailybimmer says:

    I expect it will have 650 Nm, 470-507hp at a weight of 1550 kg. 0-100 km/h in 3,6 secs.

  3. Kaisuke971 says:

    They need to go permanent AWD, AWS, lightweight, next gen ZF, and they can build a car that’s somewhere between a Nissan GT-R and a 911 Turbo in terms of hiw it drives. I still think it’s too early for electrification in that segment (weight penalty is still too big) and really if they focus on the weight with around 500hp they can build something that’ll almost revolutionize the segment with a simple formula: massive grip. From there on matbe they can experiment on the CS but for the base car and the competition that’s what they should do

  4. Dailybimmer says:

    The toughest competitor of Bmw M3 is of course Alfa Guilia Nring (RWD) with 510 hp, but next generation Alfa Romeo will also be stronger and have more torque. If next gen M3 switch from RWD to AWD, as we know it from M5, and add some batteries, it will surely have more weight than the outgoing M3 CS, but it will also be much faster on the straight line, thanks to AWD, more horsepower and more torque.

    According to current Bmw’s philosophy AWD makes only sense for real Bmw M cars beyond 750 Nm or 600 hp (M5, M8), except M performence cars.

  5. Alexander S says:

    No AWD and mid-hybrid? What’s the point to increase power if even the current M3/4 can’t handle all the torque? What will be main point for customer comparing to its main rivals? If they’ll add AWD and reduce weight it will be lighter than C63 and RS4 in any case. Who needs lighter and more sporty M3/4 they could choose CS. They made AWD in new M5 without increasing significantly weight, hope they’ll make it in new M3/4.

  6. Dailybimmer says:

    Sources say new M3 will be 60-70 kg lighter. If they add AWD system from M5 (+ 50 kg), would mean that the new M3 is still 15 kg or so lighter than M3 CS.

  7. Max says:

    Most important thing to me and so its stil the only one in the segment would be one big reason to buy this car over all the others ;)

    Making the normal thing AWD with the optional “Fun Button” like in the M5 would probably be fine for most of the people.

    And later they can do a hardcore version with RWD only and sell it like crazy :D
