The BMW Z4 M40i will get a power boost for 2020, and a significant performance improvement to go with it.
But Z4 M40i buyers from early in 2020 will get an uprated version of the same engine making 285kW and 500Nm – identical to what's on offer in the M340i xDrive and X3 M40i with which the roadster shares its engine.
The result is a claimed 4.1-second sprint to 100km/h.
BMW hasn't changed pricing, keeping the sticker at $124,900 before on-road costs.
Previously, the Z4 M40i was good for a claimed 100km/h sprint time of 4.5 seconds – slightly slower than Toyota's claim of 4.4 seconds for the Supra.
But real-world tests of the Supra have returned times as low as 4.2 seconds to 100km/h, suggesting it's more powerful than Toyota is letting on.
