The all-new 2015 BMW M4 Convertible will make its world debut at the 2014 New York International Auto Show and arrives in US showrooms late this summer to join the M4 Coupe and M3 Sedan. Powered by the same BMW M TwinPower Turbo 3.0-liter inline-six as its siblings, its engine produces 425 horsepower and 406 lb-ft of torque and can be mated to either a 6-speed manual or 7-speed M-DCT transmission.

Like the new BMW M3 Sedan and new BMW M4 Coupe, the new M4 Convertible sees a return to an inline-six engine, as used on the second and third generations of this iconic open sports car. The new turbocharged engine combines the best of both worlds – reaching a maximum 7,600 rpm, it is unusually high-revving for a turbocharged engine, resulting in linear power delivery over a wide engine speed range and a soulful engine note, while M TwinPower Turbo technology ensures that peak torque is on tap over a broad rpm range. A further hallmark of this engine is its outstanding efficiency.
