Both cars share the same engine
The BMW is 580 pounds heavier
The Toyota easily won each of the 3 races
The current Toyota Supra is based on a BMW platform and it has a BMW engine, to the chagrin of many fans of the original Supra, but that might not be so bad, as a drag race between a GR Supra and a BMW M440i proves.
A drag race set up by the Sam CarLegion Youtube channel pitted a GR Supra against a BMW M440i convertible, both equipped with the same turbocharged six-cylinder engine and 8-speed automatic transmission.
Despite having a sport mode on its transmission, which the Supra doesn’t have, the BMW lost every one of the three drag races.
This is due to the much heavier weight of the M440i, which tips the scale at 3,977 pounds, 580 pounds (263 kilograms) more than the Toyota.
Both vehicles have 382 horsepower at their disposition and while the Supra has one more lb-ft o torque, at 369, this is not enough to explain this performance.
The BMW lurched ahead of the Supra on both launches from a stop for about a second before the Toyota smoothly pulled away and left the BMW to bite the dust.
On the 50 km/h (31 mph) rolling start, the M440i didn’t stand a chance since the Supra disappeared in front as soon as the driver floored the gas pedals.
Both of the cars used in this test were rear-wheel drive and it is likely the BMW would have faired better if it was equipped with the optional Xdrive all-wheel drive system, which isn’t offered on the Supra. This system would have permitted stronger starts from the German convertible and testing showed that Xdrive M440i models are three-tenths of a second quicker to 60 mph than the rear-wheel drive versions.
Nevertheless, this would not have been enough to beat the Toyota, which shows how important weight is in a performance car, not just for handling, but also for straight-line acceleration.
