Just a few days after the 4 Series Convertible broke cover, the M4 version has been spied up close.
Just over a week after the new M3 and M4 debuted, BMW presented the brand new 4 Series Convertible. It's now only a matter of time before the M4 also drops its top, but while the official reveal is still likely several months away, our spies have provided some close-up shots of the next-generation M4 Convertible in prototype form being put through its paces by a BMW test driver. In truth, this isn't the first time we've seen the new M4 Convertible being tested, but this latest prototype has started strip teasing since our last sighting.
Since the new M4 Coupe has already been revealed in all its glory, we now have a clear idea of what its convertible sibling will look like. BMW didn't bother covering up the sides, revealing the prototype's Frozen Blue paint finish.
All of the M4 Coupe's design changes will carry over to the convertible, including the massive grille that's dividing BMW M enthusiasts. Sporty enhancements such as wider fenders, a prominent front apron, and a diffuser incorporating a quad exhaust system will set the M4 Convertible apart from the standard droptop 4 Series.
While the previous model was fitted with a hardtop, the new M4 Convertible will have a lighter soft-top roof, which was folded up on the prototype. In the regular 4 Series droptop, the roof is around 40 percent lighter and can be opened or closed in 18 seconds up to 31 mph. It's also no secret what will power BMW's new open-top M sports car.
Like the M4 Coupe, power will be provided by a 3.0-liter twin-turbo in-line six-cylinder producing 473 horsepower and 406 lb-ft of torque in the base model and 503 hp and 479 lb-ft in the Competition version. A six-speed manual will be offered in the base model, while the Competition will only be available with an eight-speed automatic. Power will be sent to either the rear- or all four wheels. BMW's xDrive all-wheel-drive system will be available for the M4 Coupe Competition next summer, so the convertible should be available with both options when it launches.
It remains a mystery when BMW will reveal the new M4 Convertible, but it should break cover within a few months either later this year or early next year.
