And we’ve got video proof of the 7min25.8s lap time
BMW tuner AC Schnitzer is keen to show its cars not only look fast but go like that as well.
The best example is the ACL2 concept vehicle that's loosely based on the BMW M235i Coupé. Thanks to an upgraded M4 engine, lightweight body, and a raised top speed, the AC Schnitzer ACL2 proved itself on the Nürburgring Nordschleife by setting a phenomenal time.
Driven by Touring Car and Truck racing driver Markus Oestreich, the ACL2 lapped the "Green Hell" in just 7 minutes and 25.8 seconds, making it the fastest road-legal BMW on the treacherous track. Mind you, the ACL2 is not quite a production car, but it's registered and so can be driven on public roads.
For AC Schnitzer, concept vehicles are the link between motorsport and series production. That's why the ACL2 study formed the development basis for the Anniversary Model ACL2S which is limited to just 30 examples.
The twin-turbo 3.0-liter inline-six engine is sourced from the M4 and boosted to 570 hp, with the ACL2 having many other tricks up its sleeves (or flared wheel arches, if you like).
Those include an adjustable Clubsport suspension, a limited slip plate differential, as well as a refined aerodynamic kit consisting mostly of carbon components that contribute to a weight-to-power ratio of just 2.59 kg/hp. That puts the ACL2 on par with supercars such as the Ferrari 458 Italia or the Porsche 911 GT3 RS.
You can watch an onboard footage of the full lap in the following video. Enjoy!
