Our friends at Axis took the 1M to the track and did a direct comparison to the other BMW in the garage; their heavily modded Z3 M coupe. From all accounts the two were very close in speed with the nod going to the more modded M Coupe.
>What do we see from the data? well, while it ‘s not the perfect comparison because it ‘s two different drivers, it ‘s amazingly close. I was surprised by the acceleration curves being so matched but I think I had to work much harder to get there than Eddie did even with an almost 300 lbs weight advantage. Slap some fresh Hoosiers on that puppy by and you got something pretty awesome on your hands.
