BMW M135i (2012-2019) review

The M135i may not have the twin-turbo 3.0-litre straight six of the old 1 M Coupe, but its new-generation single turbo equivalent is almost as scintillating. With 326bhp, it’s very nearly as powerful, and the M modifications that improve response and sound add to the enjoyment, too. It has masses of mid-range pick-up and charges to the red-line with a vim and a voice that harks back to classic BMW straight-sixes.

It corners as well as the rate at which the bends explode towards you. Steering is super-direct, well-weighted and progressive, grip is near-unshakable and, impressively, the balance is equally tight at both ends of the car. You won’t break the rear tyres’ traction by accident. But 331lb ft means you can if you want.
