BMW M6: E24, E63 and F13 generations, engines and trims
BMW M6 — the sporty M coupe and convertible with a tradition dating back to 1983 with the M635CSi. In Lithuania today, the E63 generation with the V10 engine and the F13 generation with the twin-turbo V8 are most sought after. We look at the differences between the generations, engines, and key inspection points.
M6 in brief
The M6 has always been the sporty version of the BMW 6 Series: powerful engine, reinforced suspension, special brakes, and M-specific details. Body styles include the coupe, convertible, and the F generation added the Gran Coupe with four doors.
This isn't your everyday economical car. The M6 is bought for its power, sound, and prestige, so maintenance costs, fuel consumption, and insurance are all high.
Which generation to choose
E24 M635CSi (1983–1989) — the classic coupe with a 3.5-litre inline-six S38 engine, now a collectible car. Suitable for enthusiasts, not daily use.
E63/E64 M6 (2005–2010) — coupe and convertible with a 5.0-litre V10 engine (S85), around 507 hp and a 7-speed SMG robotic gearbox. A famous and unique engine, but it demands meticulous maintenance.
F12/F13/F06 M6 (2012–2018) — the main modern generation with a 4.4-litre twin-turbo V8 (S63), around 560 hp and a 7-speed M DCT dual-clutch gearbox. Coupe, convertible, and Gran Coupe; a Competition package with more power was also offered.
Engines and gearboxes
E63: 5.0-litre V10 (S85), around 507 hp, 7-speed SMG. The gearbox can be rough, and its hydraulics require attention. A manual gearbox was not offered.
F13: 4.4-litre twin-turbo V8 (S63), around 560 hp, Competition package — around 575–600 hp. Gearbox — 7-speed M DCT, rear-wheel drive. Fuel consumption is high, but the car and brakes are geared towards high speeds.
What to check when buying a used M6
Ask for the full service history: oil changes should be frequent, and servicing should be done at a specialist centre. V10 engines (E63) are notorious for head gasket failures, so it's worth consulting with a specialist and checking the engine.
SMG and M DCT gearboxes should shift smoothly, without juddering or error messages. Test the brakes, clutch (SMG), and check for any engine faults.
Check if the car hasn't been track-used or modified — M6s often have additional software or exhaust systems. Inspect the condition of tyres and brake discs, which can be costly.
