So with all of the discussion on how much power the new M3/4 will have, I got bored and made a chart for us.
So here you have a chart 1992-2012, B/A is the ratio of horsepower the BMW had vs. the Audi, B/M BMW vs Mercedes.
So how does it all fare:
- B/A average (0.934) and B/M average (0.982) are similar. The overall comparison is 0.968.
- On average all three manufacturers jump by 40-50 hp per generation (I ignored the C34 to C55 jump since they were both W203). The smallest jump was the E36 to E46 (only 17 hp).
- Generational increase is 13.3% on average, but varies widely from 5.1% to 24.59% (st. dev. of 7.9%!)
Now why did I do this? (other than being burnt out from a 3 hour teleconference) First off, I think the M3/4 will have an increase in power. Simple marketing dictates that it MUST.
So what can we expect? Since even the E36 to E46 jump was 17 hp, I think it is safe to assume 430hp is assured. If we go by percentage increased: 435hp.
What do I think (as if you cared, since I am just some random guy with excel and too much time)? 440-450hp. I think that will be the sweet spot. It will be close enough to the RS4/5 and the C63. The next C-AMG (I am guessing they will reuse the C55 name for it), will likely have even more power but will be unlikely to be able to handle as well as a BMW.
So... ya, that was fun.
Interesting trends: Audi's increases have been declining while Mercedes' have been increasing. BMW seemed to really try and play catch-up with the E9X models (with the strange coincidence in hp to the B7 RS4).
