It's lighter weight versus more power (and AWD).
Courtesy of Shmee150, we have a classic half-mile drag between a BMW X6 M putting down 650 hp to all four wheels and a rear-drive Ferrari 458 Spider tuned to 630 hp by Evoms. The battle went down on the runway at Shift S3ctor Airstrip Attack 7. As you would expect, the XDrive system and added grip means the X6 M, powered by a 4.4-liter twin-turbo V8, absolutely flies off the line. But over the half-mile, the Ferrari’s lighter weight coupled with a juiced 4.5-liter V8 pays dividends.
