BMW's 3.0-litre six-cylinder twin-turbo engine delivers 317kW of power between 5500-7300rpm and 550Nm of torque between 1850–5500rpm, and redlines at 7600rpm.
The new engine represents a significant step up from the previous M3 Convertible, which produced 309kW/400Nm from its naturally aspirated 4.0-litre V8-powered, though redlined at 8400rpm.
The BMW M4 Coupe weighs 1497kg, and the addition of a folding roof is expected to add about 60-80kg. The fixed-roof model claims a 4.1-second 0-100km/h sprint when fitted with the optional seven-speed dual-clutch automatic transmission (4.3sec as a manual). The convertible is likely to be one or two tenths slower to triple figures.
The M4’s top speed will be limited to 250km/h, though - in Europe at least - an optional M Driver’s Package will increase that to 280km/h.
The BMW M4 Convertible is destined to reach Australian showrooms before the end of the year following its anticipated third-qurter international launch.
