BMW has unveiled its much awaited M4 Convertible to the world. The convertible has been developed by the boffins at M Division who have made extensive use of lightweight materials including aluminum and CFRP (Carbon Fibre Reinforced Plastic) in its construction. The M4 Convertible is the latest addition in the long line of performance cars developed by the Munich based automakers M performance division.
The M4 looks like a proper sports car and features the signature kidney grille. The looks are sleek and sporty with aggression to be seen all around. Displaying the aggression is the dome on the bonnet along with the flared wheel arches housing the 18-inch alloys with 19-inchers available as options. The twin stalk side mirrors and a sharp shoulder line define the side profile. Twin set of tailpipes integrated at each end of the diffuser and the subtle boot spoiler provide both form and functionality.
Performance is ballistic as expected but takes a minor beating owing to its weight of 1750kgs, more than 274kgs heavier than the M4 Coupe. The 3.0litre, inline, six-cylinder engine with M’s TwinPower turbo makes 431bhp and has a turning force of 550Nm. 0-100kmph comes up in just 4.6 seconds (claimed) with the standard 6-speed manual transmission but BMW says that it is reduced to 4.4 seconds if the optional 7-speed double clutch autobox is opted for. The power mill has a high revving characteristic with the redline peaking at 7600rpm, it will happily scream its way to the electronically limited top speed of 250kph (155mph). The M4 gives a claimed combined fuel efficiency figure of 10.9kmpl with the standard transmission and has a carbon footprint of 213g/km. Practicality is almost taken care of and those not-so-long weekend drives can be undertaken with 220litres of boot space which increases to 370litres with the roof up. Yes and one more thing. The roof, by the way, is a three-piece folding metal unit that completes operation in 20 seconds and at speeds of up to 17.7kph (11mph).
The interior is quite similar to the 4-series with the sport seats wrapped in Merino leather welcoming you. The dashboard is dominated by a 6.5 inch tablet like screen which displays information such as rev counter, gear display and even an optimum gear shift indicator. If you opt for the navigation system that tablet size will increase to a huge 8.8 inches. The M theme is found all around the cabin, from the steering wheel, gearshift lever, door sill finishers to the driver’s footrest. The car handling and dynamism is made better by employing Active M Differential, electric assisted power steering and standard M compound brakes. Steering system and the optional Adaptive M suspension have three modes- Comfort, Sport and Sport+ to cater to different situations and taste of the driver.
Overall, the M4 is a good package with its combination of weight saving and race track technology. The top down version of the M4 Coupe offers great looks and sporty performance with the added advantage of wind-in-the-hair experience. The M4 Convertible is not a major step ahead and if M fans were looking for a machine which will set the track ablaze, they will be disappointed. Once launched it will face-off with the Audi RS5 Cabriolet. Deliveries in UK will start by September with a price tag of about 60,730 pounds.
