1 Series is now more powerful than the last generation of M3
A German tuner has boosted the BMW 135i coupe to 350bhp – making it more powerful than the last generation BMW M3.
The BMW 135i coupe is a sleek two-door version of the baby 1 Series hot-hatch and comes with 300bhp as standard.
Now Hartge – who specialise in tuning BMWs – have upped the 135i coupe’s twin-turbocharged 3-litre engine to a massive 350bhp.
And the performance figures are on par with the new V8-powered BMW M3 – 0-62mph takes just 4.8 seconds, and the Hartge-tuned 135i coupe will hit a top speed of 174mph, which is faster than any standard BMW.
