All New BMW M4 Competition Convertible with Soft Top


BMW’s all-new M4 Competition Convertible with xDrive, debuted today and will be here ins Australia by the end of the year

Outside: in particular, the new bow softtop roof,

BMW has ditched the old folding tin roof in favour of a classic softtop. The softtop is 40% lighted than the old tin roof too. The roof can be opened or closed while moving, and takes 18 seconds to complete the dance.

With the roof down, the boot has a 300 litres capacity, which is 80 litres more than the old model. With the roof up, the boot increases to 385 litres.

Like the 3 and 4 series models, the convertible gets the vast, gaping, BMW kidney grille. Some find it confronting, and other ask what on earth BMW was thinking.

Adaptive LED Headlights with BMW Laserlight are standard on Australian-delivered cars. These light up the night with a daylight-like effect.

M4 Competition Convertible gets big flared wheel arches, M Side Gills , and large extended side sills which, with the attachment parts for the front and rear aprons form a black band around the entire car.

The rear end features two fat pairs of tailpipes, something all M owners have come to expect..

If you want to spend even more money, you can option the M Carbon exterior package, with  front bumper, mirror caps and rear diffuser made of carbon fibre.

You can change 4WD bias in the setup menu to set your own preferred  tastes.

For track days, you can turn the DSC off, which puts the car Xdrive in to 2WD mode. In this mode, the electronic nannies do not engage, so you are on your own.
