Drag coefficient
So typically M cars have been known for their top end ability. In the e46 era when people compare EVO with M3 and M3 will edge out because of its engine in triple digits and slicker design. Will M division address 1 series' drag coefficient now it joins the M rank?
On cars I am familiar with. is350 has a drag of .28 335i coupe has a drag of .30 135i has a drag of .34 M5 has drag of .31 |

If I remember correctly, the e46 M3 had a drag coefficient of .35
More for comparison: e90 M3 drag coefficient: 0.30 e92 M3 drag coefficient: 0.31 e93 M3 drag coefficient: 0.32

Second, How would the folks at M address the 1's less than stellar Cd? They're not redesigning the car, they're modifying an existing car. In other words, they're stuck with what they've got, though they MAY be able to work some things in to get it to .33 IF they think that's worthwhile. This is doubtful since the time frame and budget are going to be relatively low for the project given it's ~2 yr likely production run. They'd also be fighting against the fender flares and the wider wheels and tires M is installing. In other words, the Cd may go up. |

Taking your assumption, we already 135i as an all around vehicle at low speed, then does it make sense to buy a M1. |

The M1 will be just fine at high speed. The M guys know what they are doing

My 2000 M Roadster had a CD of 0.420 and it was rock stable at high speed.

Fastest I ever had the car was 143mph. I'll never forget it - it was the first time I was over 140

I can't recall if this is correct or not but drag co has less of an affect on top speed as much as frontal area. So if true then it's this that needs to be right more than what drag it's producing.
