The all-new BMW M3 sedan and M4 coupe were revealed late last year. And now it’s the turn of the M4 convertible to step into the spotlight. There’s not much to say really. It’s virtually identical to the M4 coupe except the chassis is a less rigid, the load space is smaller and its got a fold-away roof.
Powering the BMW M4 Convertible is the same 3.0 litre in-line six-cylinder twin-turbocharged engine used in the M3 and M4 coupe. This engine produces 431 horsepower and is mated to a six-speed manual gearbox as standard, or an optional seven-speed M Double Clutch transmission. Fitted with the seven-speed transmission, the BMW M4 convertible can hit 62 mph (100 kmh) in just 4.4 seconds. The top speed is an electronically limited 155 mph.
The new M4 Convertible is around 60kg (120 lbs) lighter than the outgoing M3 Convertible, despite being better equipped. The reduction in weight has been achieved through extensive use of aluminium for the bonnet, front wings and many of the chassis components, while carbon-fibre reinforced plastic (CFRP) is used for the propeller shaft and strut brace in the engine compartment.
