Top specs, facts and figures

General info

1.Has dual-clutch transmission
BMW M4 Convertible (2015)
BMW M6 Convertible (2015)

A dual-clutch transmission (DCT) is an automated manual transmission that allows the driver to control gear-shifts themselves or to let the computer decide. Upshifts are extremely fast, resulting in smooth acceleration, and due to the uninterrupted power flow it also has the benefit of increasing fuel efficiency.

2.Has fully independent suspension
BMW M4 Convertible (2015)
BMW M6 Convertible (2015)

This allows all four wheels to move up and down independently, providing a smoother ride when, for example, going over bumps in the road.

3.Has a petrol (gasoline) engine
BMW M4 Convertible (2015)
BMW M6 Convertible (2015)

A petrol (gasoline) engine offers several advantages over diesel. For example the engines tend to be lighter and cheaper than their diesel counterparts. Petrol engines also tend to have higher horsepower, and the fuel is more readily available.

4. longer basic warranty (years)

4yrs

4yrs

The basic warranty of a car covers all aspects other than parts which are subject to normal wear and tear, such as windscreen wipers and brake pads. It lasts either a certain number of years or amount of kilometres driven.

5.Has rear-wheel drive
BMW M4 Convertible (2015)
BMW M6 Convertible (2015)

Rear-wheel drive benefits from increased traction when accelerating, as the weight of the vehicle shifts to the rear over the drive wheels. The weight of the car is also more evenly distributed, resulting in improved handling.

6. smaller turn radius

12.2m

12m

The turn radius indicates the smallest circular turn a car can make. With a smaller turn radius it is easier to perform a U-turn in one attempt instead of having to reverse back and forth in order to turn around.

1. better fuel economy (highway)

7.2l/100 km

10.7l/100 km

Fuel economy is a measurement of fuel efficiency, based on how far you can travel with a certain amount of petrol (gasoline). A lower fuel economy means the car will be cheaper to run.
