📖BMW 2 Series Coupé G42 (2021-present): modern rear-wheel-drive sports coupé preserving authentic BMW performance genetics

BMW 2 Series Coupé G42 (2021-Présent)

Debuting in late 2021, the second-generation BMW 2 Series Coupé G42 delighted driving purists by remaining faithful to BMW’s longitudinal rear-wheel-drive architecture. Built on a shortened adaptation of the CLAR platform shared with the 3 Series and 4 Series, it boasts 12% greater torsional rigidity and wider front and rear tracks. Preserving the razor-sharp handling of this modern coupé requires methodical BMW 2 Series maintenance, centering on fluids and electronics.

The powertrain lineup is anchored by the 2.0-litre turbo B48 (220i, 230i) and the sensational 3.0-litre twin-scroll turbo B58 straight-six in the M240i (374 hp), available with rear-wheel drive or rear-biased xDrive all-wheel drive. Power is handled exclusively by the eight-speed ZF automatic transmission. Key service items include keeping the dual cooling circuits topped with approved coolant and monitoring differential fluid levels.

Owner notes

The reassuring points, known weak spots and deadlines you should not let slip.

Reassuring points

Reliability
  • Authentic CLAR longitudinal architecture delivering true rear-wheel-drive sports coupé dynamics.
  • Monumental acceleration, silky refinement, and durability from the 374 hp B58 straight-six engine.
  • Exceptional chassis rigidity and high-speed stability derived from 3 Series and 4 Series componentry.

Chronic weak spots

Keep an eye on
  • Dual cooling system on B48/B58: check main and indirect intercooler expansion tanks for coolant loss.
  • ZF 8-speed automatic transmission: ensure smooth low-speed gear engagement and verify software updates.
  • xDrive transfer case on M240i: keep tyre tread depth matched across both axles to avoid transfer clutch wear.
  • Front tyre inner shoulder wear: inspect wide 19-inch tyre setups for negative camber wear.

Critical deadlines

Do not miss
  • Engine oil and filter change: every 15,000 km or 12 months with BMW LL-17 FE+ or LL-04 oil.
  • ZF 8HP automatic gearbox fluid renewal: recommended at 80,000 km.
  • Spark plug replacement: every 40,000 to 50,000 km on M240i.
