When Vauxhall imported the Holden Gen-F GTS to the UK and rebadged it as the VXR8 GTS, its goal was to offer an alternative to the segment’s benchmark, the BMW M5. But can the Vauxhall VXR8 GTS rival the M5? To find out, Autocar drove the two cars back to back.

With 577 hp produced by a 6.2-liter supercharged V8, the Vauxhall VXR8 sprints from 0 to 62 mph (100 km/h) in 4.9 seconds and reaches an electronically-limited top speed of 155 mph (250 km/h).

The BMW M5 Competition Package has 567 hp produced by a 4.4-liter turbocharged V8, allowing it to go from 0 to 62 mph in 4.2 seconds and to reach a limited top speed of 155 mph (250 km/h).

While the duel seems to be balanced on paper, the two cars are very differently priced. The VXR8 GTS costs £54,499 in the UK, while the BMW M5 Competition Package starts from £80,205. So how different are the two sport sedans in real life? Find out by scrolling down to watch the review.
