The M6 occupies an interesting position in the BMW M portfolio, placed as a grand tourer between the M5 Sedan and the M flagships, but without a wholly distinct technical identity. The E63/E64 generation (2005-2010, Coupé and Convertible) shares the S85 5.0-litre V10 with the E60 M5: 507 hp, a naturally aspirated ten-cylinder technically related to the BMW Williams F1 engine from the 2000-2009 BMW Formula 1 programme. The US market received this generation exclusively with a manual six-speed gearbox, around 1,060 cars total. The F12/F13/F06 generation (2012-2018, Convertible, Coupé and Gran Coupé) replaced the V10 with the biturbo 4.4-litre S63 V8 from the F10 M5: 560 hp standard, 600 hp in Competition Package from 2014. The F06 M6 Gran Coupé is the first and only four-door M6 in BMW M history. From 2019 the M6 was replaced by the M8.
BMW M unveiled the E63 M6 Coupé in 2005 and the E64 M6 Convertible in 2006 as a grand tourer variant of the E60 M5 Sedan. Both models share the naturally aspirated 5.0-litre S85 V10 with 507 hp and 520 Nm of torque. The S85 was at launch one of the most advanced production V10s in the world with VANOS variable valve timing, individual throttle bodies per cylinder, and redline of 8,250 rpm. The E63 M6 Coupé has widened bodywork, M bumpers, and carbon roof panel as weight saving. The E64 M6 Convertible has electric soft-top. Both available with manual six-speed gearbox (US market only, around 1,060 cars) or SMG seven-speed single-clutch automatic (rest of world).
The S85 V10 in the E63/E64 M6 is substantially value-adding for collectors due to its unique character. It is the first and only V10 engine that BMW M ever built in a regular production car. The S85 is technically related to the BMW Williams F1 engine (V10 from the BMW Formula 1 programme 2000-2009). For collectors the S85 in the E63/E64 M6 represents the culmination of the BMW M Formula 1 culture. The S85 has known points of attention: thrust bearing condition (specifically at high mileage), VANOS actuator condition, individual throttle body service, and oil consumption status. For collectors S85 condition is substantially value-driving.
In 2012 BMW M unveiled the new F-generation M6 as a successor to the E63/E64. The F generation includes F13 M6 Coupé, F12 M6 Convertible, and F06 M6 Gran Coupé (four-door Coupé on the 6 Series Gran Coupé base). The design was refined compared to the E63 and received modern BMW design elements. The engine was replaced: the naturally aspirated S85 V10 disappeared, replaced by biturbo 4.4-litre S63 V8 (shared with F10 M5) with 560 hp in regular specification. From 2014 BMW M added the Competition Package with 600 hp and sharpened settings. Available with M-DCT seven-speed dual-clutch gearbox or manual six-speed gearbox (US market only, limited).
The F06 M6 Gran Coupé deserves specific mention: it is the first and only four-door M6 in BMW M history. Based on the 6 Series Gran Coupé with extended wheelbase compared to F12/F13. For collectors the F06 M6 Gran Coupé represents a unique position: M6 performance in four-door configuration, positioned between the F10 M5 (regular Sedan) and the F13 M6 Coupé (two-door grand tourer). Production was relatively limited compared to F13 M6 Coupé.
The M6 line has seen a substantially mixed appreciation curve. E63/E64 M6 (2005-2010) with V10 S85 has been substantially appreciated since 2018, with manual specifications (US market only, around 1,060 cars) in the highest price tier. F12/F13/F06 M6 (2012-2018) is more accessibly priced and is strongly valued for well-documented Competition Package specifications in BMW Individual colours. For sellers this means a well-documented M6 with proven service history at BMW M Classic or recognised M specialist, original original specification, and BMW Group Classic certification attracts strong international interest.
E63 M6 Coupé (2005-2010, V10 S85), E64 M6 Convertible (2006-2010, V10 S85), F13 M6 Coupé (2012-2018, biturbo S63), F12 M6 Convertible (2012-2018, biturbo S63), or F06 M6 Gran Coupé (2013-2018, biturbo S63, four-door Coupé). For collectors confirmation of factory chassis number, model year, and market version is essential.
E63/E64 M6 has naturally aspirated 5.0-litre S85 V10 with 507 hp (shared with E60 M5). F12/F13/F06 M6 has biturbo 4.4-litre S63 V8 with 560 hp (regular) or 600 hp (Competition Package from 2014). For collectors both engines are value-adding, but V10 is generally more iconic.
E63/E64 M6 available with manual six-speed gearbox (US only, around 1,060 cars) or SMG seven-speed single-clutch automatic (rest of world). F13/F12 M6 available with M-DCT seven-speed dual-clutch gearbox or manual six-speed gearbox (US only, limited). For collectors manual is scarce and substantially value-adding; M-DCT is acceptable.
From 2014 BMW M added the Competition Package to the F-generation M6 with 600 hp (40 hp over regular M6), sharpened settings, M Carbon-ceramic brakes optional, and CS-specific wheels. For collectors Competition Package is substantially higher priced.
For E63/E64 M6: Indianapolis Red Metallic, Sepang Bronze Metallic, Silverstone Metallic, Black Sapphire, Carbon Black. For F12/F13/F06 M6: Frozen Editions (Frozen Black, Frozen Brilliant White, Frozen Silver), BMW Individual colours, and regular colours. For collectors BMW Individual specifications are substantially value-adding.
M6 service is specialist work: for E63/E64 V10 S85 (VANOS, thrust bearing condition, individual throttle bodies, oil consumption status), for F12/F13/F06 biturbo S63 (turbo condition, head gaskets, VANOS, M-DCT mechatronics). Service at BMW M Classic or recognised M specialist is essential.
For M6 collectors low-to-moderate mileage (under 100,000 for E63/E64, under 80,000 for F12/F13/F06) with full service history is more attractive. For Competition Package specifications and BMW Individual specifications low mileage is substantially value-driving.
Note: These factors may influence buyer interest. Value depends on many factors.
