2013 BMW M6 Convertible
The engine: High-Revving V8 Engine with M TwinPower Turbo Technology.
The new engine shared by the BMW M5 and M6 has the highest output ever generated by a BMW M car, and at the same time provides the most efficient balance between performance and fuel consumption. It is characterized by immediate throttle response, a linear power band and an unusually high and flat torque curve. The new engine produces around 10% higher output than the V10 engine of its predecessors and torque is up by over 30%. At the same time, fuel consumption and CO2 are expected to be reduced by approximately 30%.
To achieve the performance levels demanded by the M6, the engineers at BMW M started with the proven BMW M developed V8 engine from the BMW X5 M – X6 M (internally known as the S63) and further developed it for its duty in the latest M5 and M6 models. Internally designated as the S63Tü this new engine uses similar M Twin Power technology combined with the reverse flow V8 layout. The result is that the high-revving V8 engine with M TwinPower Turbo Technology lends a whole new intensity to the powerful thrust at higher rev ranges for which M cars are known. The 4.4-liter engine develops a peak output of 560 hp (412 kW) at 5,750 — 7,000 rpm (versus 555 hp at 6,000 rpm for the S63), while its maximum torque of 500 lb-ft (680 Nm) is on tap between 1,500 and 5,750 rpm (versus 500 lb-ft from 1,500 to 5650 rpm for the S63). The rev limiter intervenes at 7,200 rpm (up 200 rpm from the S63 engine). The rev band, which offers extremely dynamic acceleration between peak torque and the availability of maximum output, is therefore almost three times as wide as that of the V10 engine in the previous generation M6.
The engine’s exhilarating thrust gives the new BMW M6 models impressive acceleration. The instant power delivery and sustained thrust of the engine results in an acceleration of 0– 62 mph (0-100 km/h) in 4.2 seconds for the Coupe and 4.3 seconds for the Convertible. The sprint from 0–124 mph (0-200 km/h) takes only 12.6 seconds for the Coupe and 13.1 for the Convertible. The top speed of both models is electronically limited to 155 mph (250 km/h). While the engine’s output has increased by around 10% and maximum torque is up by more than 30%, the new BMW M6 models consume roughly 30% less fuel and have substantially higher range than their predecessors.
