I dont know it just doesnt add up. What transmission was used in the M235i? Let's remember the 1M is stick only.
1m was more powerful and lighter... I don't know how stiff that chassis would need to be to beat the 1M. There is something we aren't being informed of here. Also, the 1M was an actual M car and was marketed as such, this is an M line car... Some sort of twisted marketing is going on here.
