Joining BMW's M4 Coupe, which was introduced at the Detroit auto show in January, the M4 Convertible will make its global debut at the New York International Auto Show later this month. It will be powered by a variant of the same 3.0-litre, twin-turbo, straight-six engine used in the coupe, in this case rated at 431 horsepower and 405 lb-ft of torque.
BMW says the M4 Convertible can accelerate from 0-to-100 km/h in 4.4 seconds, when equipped with an optional 7-speed M double-clutch transmission. The car's three-part folding metal hardtop, which is fully lined on the inside, is said to offer excellent sound insulation as well as being well suited to winter driving. It can be opened and closed on demand in just 20 seconds – at vehicle speeds up to 18 km/h.
The M4 is one of two global debuts at New York, along with the X4 four-door hatchback.
