Ever think 390 kW is not enough power for you? Well, the German tuner G-Power agrees and has released the first details of a pair of tuning kits for the new, all-wheel drive BMW M850i.
While the Autenzell-based tuner has so far released very limited information on upgrades, it has at least revealed that two software-based power upgrade kits will be offered.
The first pushes the M Performance version of the new 8 Series coupé's twin-turbo 4,4-liter V8 petrol engine from the stock 390 kW and 750 Nm to even crazier 456 kW and 850 Nm.
And the second? Well, the two-stage package (which also includes new downpipes and catalytic converters) hikes peak outputs to 493 kW and 890 Nm. That's probably far more than the upcoming M8 will make …
G-Power has not yet released performance claims, but it is expected that tuned version of the all-wheel-drive coupé will significantly improve on the claimed 3,7 second claimed 0-100 km / h sprint time. We'll guess the electronically limited top speed of 250 km / h will also change.
Of course, G-Power is not the first German tuner to fly the M850i, with AC Schnitzer and Manhart revealing their respective upgrades (both new bodywork and wheels) late in 2018.
