    • Already severely outgunned? Car Magazine claims the new F80 M3 will have 444 horsepower from its turbo inline-6

      Bavaria, we have a problem. The new M3 is coming and it isn't packing enough of a punch under the hood. We knew it would have a turbocharged inline-6 but we did not seriously think it would only have another 30 horses on the E9X M3 with its 414 horsepower naturally aspirated V8. The new C63 AMG is rumored to have a twin turbo 4.0 liter V8 and considering the C63 AMG (in Black Series trim) already is putting out more to the wheels than this M3 will be rated at the crank let alone what the new turbo C63 AMG will put out the new M3 is going to get smacked around badly if this is true.


      Someone at BMW apparently thinks only another 30 horses is a good idea. The S65 V8 in the E92 M3 offered another 70 horsepower AT THE WHEELS over the E46 M3 it replaced. With Mercedes bringing the heat and Audi set to go to a turbo motor, this does not look like it is going to cut it. 30 more horsepower? Is this a joke?

      The only bright side BimmerBoost can see is that the new M3 may be severely underrated just like the F10 M5. Let's assume this is the case and apply what we have all seen with the F10 M5 to the new M3. That would mean 417 wheel horsepower for the new M3 despite its appallingly low crank rating. That would also mean an increase of 67 wheel horsepower over the E92 M3 which is a hell of a lot better than 30 horsepower at the crank.

      With the new turbo motors BMW is making a habit of underrating them especially in M trim. The low crank rating likely designed not to insight a horsepower war with Mercedes and Audi which is already going on anyway with Mercedes already raising the stakes in the V8 arena. Regardless, assuming about 420 wheel horsepower (which is a best case scenario with a 444 hp crank rating) BMW is not going to win the raw power battle as they did with the F10 M5 temporarily until Mercedes regains the crown.

      BMW M3 fans may be starting to sweat just a bit.

        I'm very interested to see this S55. whether is TT or biturbo, is it an N55 block (i bet it is, so does that mean open deck?), what internals does it have (S65 started busting rod bolts on the 08 model, fixed for later years), etc. this HP number is very disappointing to me and if in fact BMW is reserving the extra 30 HP for a "performance package" i'm going to lose all respect for them. I'm already on the C63 bandwagon, as i drove one and an e92 M3 back to back one day and loved the C63.

        I would bet more on the N55 top end than bottom end. Let's see how cheap BMW is getting though.

        The C63 will have a performance package too I bet.

        yeah but the M3 with performance package still won't reach what the C63 is putting down HP wise stock without the PP. I know M isn't about peak HP numbers but there has to be a point were they realize they're getting smashed by the competition. Most M3/C63/RS4 owners don't track (road course) their cars. Test drives are going to sell a lot of cars. Which one is more fun to drive? I already know Click here to enlarge

        If this undercuts the C63 by 700 pounds it isn't getting smashed. The M3 with DCT makes up for the power deficit by having the more efficient transmission, more efficient gearing, and lighter weight. Stock for stock the M3 doesn't get smashed and the C63 needs its performance package to have an advantage. That goes to show the importance of efficiency and not just raw power.
