Re mapped to 400- 450 bhp the one series would be quicker than a Z4M without the potentially savage costs of M car ownership.
Remaps increase power to around 350-375 by DMS, 400-450 is going to take serious tuning and cost a lot of money.
Even with a DMS chip the Z4M is faster - 1400kg Vs 1600kg+ in the 1 series.
Not sure why, but the 1 series is one lardy car.
M costs aren't cheap,

A C-segment on a bespoke platform would be much lighter and therefore feel less 'refined'.
Also being FWD makes a hell of a mass saving around that segment.
One might argue that a bespoke C segment might be better proportioned around its dimensions, too.

The V2 version of the Vishnu chip is supposedly good for between 95 and 110 bhp at crank over stock. I have not seen a dyno that proves this but their stage one chip certainly did what they promised.
IF it does produce 395 bhp which is the conservative end of their (as yet un proven) predicted output then theoretical times are:
135i:
Power at Flywheel (BHP) : 395
Weight without Driver (KG) : 1600
Power to Weight Ratio (BHP Per Ton) : 250.84
0 - 60 (Secs) : 4.61
0 - 100 (Secs) : 10.20
60 - 100 (Secs) : 5.59
Quarter Mile (Secs) : 12.82
Terminal Speed (MPH) : 112.08
Drag Strip Quarter Mile (Secs) : 12.72
Drag Strip Terminal Speed (MPH) : 113.34
Z4M:
Power at Flywheel (BHP) : 338
Weight without Driver (KG) : 1400
Power to Weight Ratio (BHP Per Ton) : 245.30
0 - 60 (Secs) : 4.69
0 - 100 (Secs) : 10.82
60 - 100 (Secs) : 6.13
Quarter Mile (Secs) : 12.95
Terminal Speed (MPH) : 109.38
Drag Strip Quarter Mile (Secs) : 12.85
Drag Strip Terminal Speed (MPH) : 110.62
It is certainly an interesting prospect as a used purchase in a year or two.

You just wouldn't catch me applying a chip or remap that increases the power by that amount. Reliabilty?
I am also sure that the Z4M can be remapped to 365bhp for
