BMW’s M1 has started testing ahead of its launch next year, with this prototype of the hot baby coupé undergoing trials in the firm’s home town, Munich.
The existence of the M1 was revealed by Autocar earlier this year, and now these pictures confirm that the car will be based on the 1-series coupé rather than the hatchback.
The car will use a modified version of the 535i’s 3.0-litre straight-six powerplant, but fitted with two turbochargers instead of one.
Output is expected to be around 350bhp, making the M1 easily the most powerful car in its class, while torque should be raised from the 135i Coupé’s 295lb ft to around 310lb ft.
That grunt, and a relatively modest kerb weight of around 1500kg, should ensure a 0-60mph time of around 5.5sec.
The car’s flared wheel arches, used to accommodate the M1’s wider tracks, are visible in our pictures, along with the modified front bumper with its larger air intakes. However, it doesn’t look like the M1 will inherit the current V8 M3’s bonnet bulge.
