Now let's add the M2 and C43 to the mix
New C43 , given its weight disadvantage and auto ’box not suited to track use, it fared quite well, with a fastest time of 1 min 15.3 recorded, against the M2 Beemer jägerbomb’s really quick 1:13.8.
By comparison, the A45 hatchback manages a 1:14.6 around Zwartkops (as recorded by the instructors of the AMG Driving Academy) - slightly faster than its heavier stablemate, but still about a second off the time of the super quick M2.
I wonder what the M135i LCI and M140i would do on the same track.
