Where the Supra reaches 60 miles per hour in a claimed 4.1 seconds, the BMW Z4 will do the deed in just 3.9 seconds. Sure, you might not be able to measure than two tenths' difference on your stopwatch, but for internet bragging rights, every tenth of a second matters.
Of course, it's not exactly a fair fight when the BMW packs a bigger turbocharged punch. The BMW Z4 M40i packs 382 horsepower and 369 pound-feet of torque from its turbocharged 3.0-liter inline-six engine, and weighs 3,443 pounds. The Supra, meanwhile, extracts 335 hp and 365 lb-ft from its version of the same engine, with the car's curb weight listed at 3,397 lbs.
