BMW M Test Driver Joerg Weidinger on the Estoril Race Track. 360° video. More at: https://www.bmw-m.com/M8 . BMW M8 Coupé: Fuel consumption combined: 10.8 – 10.7 l/100 km. CO2 emissions combined: 246 – 243 g/km.
The fuel consumption and CO2 emissionswere determined
based on the new WLTP test cycle and have been translated
back into NEDC-equivalent values in order to ensure
comparability between the vehicles. They may vary depending
on the tyre format specified. With respect to these vehicles,
for vehicle-related taxes or other data based (at least inter
alia) on CO2 emissions, the CO2 values may differ from the
values stated here (depending on national legislation).
