📖BMW 8 Series Coupé G15 LCI: focused luxury grand tourer demanding disciplined cooling and transmission upkeep

BMW 8 Series Coupé (G15 LCI, facelift 2022) (2022-Présent)

Updated in 2022, the BMW 8 Series Coupé G15 LCI remains one of the most striking luxury coupés of modern times, blending muscular proportions with serious grand touring capability. The facelift brought an illuminated Iconic Glow kidney grille, a larger 12.3-inch central touchscreen and revised interior accents, enhancing an already sumptuous cabin. Preserving its high-speed poise and mechanical integrity requires disciplined BMW 8 Series maintenance, particularly targeting thermal management and running gear.

The engine palette features the 840d xDrive powered by the B57 diesel with 48V mild-hybrid tech, the sweet-revving 840i with the B58 straight-six petrol, and the flagship M850i xDrive with the 530 hp N63B44T3 twin-turbo V8. The standard ZF 8-speed automatic gearbox pairs with intelligent xDrive and an M Sport rear differential. Standard adaptive M suspension and optional active anti-roll bars ensure sharp turn-in while taming the car's substantial kerb weight.

  • Seamless ZF 8-speed automatic gearbox paired with sure-footed xDrive traction in all weather conditions.

Chronic weak spots

Keep an eye on
