The BMW M8 is hardly begging for more power. In fact, the M8 Competition is jointly the most powerful car BMW makes, using the same 4.4-liter twin-turbocharged V8 engine that's found in the M5 and that generates up to 617 horsepower. So quick is the M8 that it recently blitzed the Nurburgring in just over 7 and a half minutes, making it one of the quickest BMWs ever. AC Schnitzer obviously didn't think that this was enough performance, though, so the tuning company decided to increase the M8's power even further, with predictably explosive results.
The tune increases outputs to 720 hp and 627 lb-ft of torque, easily eclipsing the M8 Competition's 617 hp/553 lb-ft. In a video shared on YouTube, the modified M8's digital instrument cluster is shown as it flies towards its top speed, with 124 mph (200 km/h) demolished in 10 seconds and, not much longer after this, a top speed of 194 mph is reached. It's a bit more challenging to see the 0-60 time as the initial portion of the video is dark, with the digital display not visible, but the M8 Competition already completes this sprint in just three seconds dead, so any improvement on that is remarkable.
This isn't the first time that AC Schnitzer has cooked up some viciously powerful BMWs, though, having tuned Bimmers for over three decades. That adds peace of mind for M8 customers who may be interested in the upgrade, which also comes with a warranty and an homologation certificate. According to AC's website, the "plug and play" upgrade can be used in combination with the tuner's silencer for the M8. Even better, with BMW's latest xDrive all-wheel-drive system in place, the coupe should be able to handle the extra power without too much drama, as the video clearly demonstrates.
