BMW M4 Convertible: price, pictures and specs

The BMW M4 Convertible is faster and more efficient than the car it replaces. The M4 Convertible gets a folding metal roof, which can drop in just 20 seconds at speeds of up to 8mph, and beefy body kit that distinguishes it from lesser models.

The BMW M4 Convertible gets the same 3.0-litre engine that will feature in the new BMW 3 Series M3 saloon and the BMW 4 Series M4 Coupe. The engine produces 423bhp, gets the car from 0-62mph in just 4.6 seconds, and could fly well past is electronically limited top speed of 155mph, given half a chance. Buyers can also opt for a seven-speed auto (costing £2,645), which means 0-62mph take just 4.4 seconds.

The new BMW M4 Convertible is lighter than the M3 it replaces and this factor combines with BMW’s clever EfficientDynamics fuel-saving technologies, such as stop-start and brake-force regeneration, to return a relatively impressive 31.5mpg (32.5mpg when fitted with the seven-speed automatic gearbox). Opting for the auto also drops emissions from 213g/km to 203g/km, although the cost of annual road tax remains the same at £285.

The BMW comes complete with an impressive array of electronics, which should mean it corners even faster than the model it replaces. The car also allows the driver to customise its setup to their driving style and both the steering and the suspension have three levels of adjustment – COMFORT, SPORT, and SPORT+. The new car’s brakes are also uprated over the standard BMW 4 Series’ for faster stopping.

To mark it out from lesser models in the 4 Series range, the M4 gets numerous exterior touches including a more imposing bonnet, ground-hugging front spoiler, a black double-slat ‘kidney’ grille, wider wheelarches, four exhaust pipes, and a set of M4-specific 19-inch alloy wheels.

The most important interior feature is the folding metal roof, aside from being quick to operate and usable at speeds of up to 8mph, the roof is also better insulated than the version found in the old M3 Convertible. The result, according to BMW, is that the cabin is up to 2dB quieter than the old model’s. A loading-aid raises the folded roof (when it’s stowed in the boot) in six seconds to give owners access to their belongings. Roof down, boot capacity is limited to 220 litres, but that leaps to 370 litres with the roof up.

Inside, you get plenty of reminders that you have splashed out on the top-of-the-range model and the M4 gets sports seats, an illuminated M logo on the front seats, an M-sports steering wheel, chrome trim, and three-colours of M stitching. A three-stage air collar is also available. It pumps hot air up to the front passengers’ neck when the roofs down.

Standard-fit equipment includes a Bluetooth phone connection, front and rear parking sensors, air conditioning, electrically folding mirrors, and heated front seats.

The BMW M4 Convertible will reach UK showrooms on 6 September and will be priced from £60,730. For all the latest reviews from across the BMW range, visit the Carbuyer BMW reviews page.
