BMW wants to make it clear the Z4 is faster off the line than the Supra.
After a 21-year hiatus, the Toyota Supra made its triumphant return at Detroit this week. Under the hood is a turbocharged scroll 3.0-liter inline-six that produces 335 hp and 365 lb-ft of torque – the same engine that powers the new 2019 BMW Z4.
It came as a surprise, then, when Toyota confirmed the Supra will sprint from 0-62 mph in 4.1 seconds since this is faster than the Z4’s reported 4.4 second-sprint time, despite the Z4 having more power (and being only marginally heavier). Unsurprisingly, it seems BMW was being conservative about the Z4’s performance - it wouldn't be the first time BMW has underestimated its power figures.
Since the Supra’s debut, the automaker has revised the Z4’s 0-62 mph time to make it clear it’s a faster car than the Supra. According to BMW, the range-topping Z4 M40i will now hit 62 mph from a standstill in 3.9 seconds – a full half a second faster than the automaker’s previous estimate. BMW has also confirmed the Z4 will have a curb weight of 3,443 lbs and gross vehicle weight of 4,092 lbs.
At 3,443 pounds, the Z4 M40i is only 46 lbs heavier than the Supra which tips the scales at 3,397 lbs. It also has 47 more hp, so the updated specs make sense. BMW hasn’t updated the specs of the Z4 sDrive30i, however, which the carmaker claims will do the 0-62 mph sprint in an estimated 5.2 seconds.
Like the base model Supra offered in Japan, the entry-level Z4 sDrive30i is powered by a 2.0-liter turbocharged 4-cylinder producing 255 hp and 295 lb-ft. The Z4 M40i, on the other hand, is powered by a 3.0 liter six-cylinder unit tuned to deliver 382 hp and 369 lb-ft of torque. Official pricing hasn’t been confirmed, but previous leaks suggest the Z4 will start at $64,695 in the US.
