General info

1.Has rear-wheel drive
BMW 6 Series Convertible 640d (2014)

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.

2.Has a diesel engine
BMW 6 Series Convertible 640d (2014)

Improvements in diesel engine technology have lead to vast gains in fuel efficiency over petrol (gasoline) cars (and even hybrids), as well as having lower carbon emissions. It is also safer as it doesn't explode as petrol can.

3.Has fully independent suspension
BMW 6 Series Convertible 640d (2014)

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

4. less CO2 emissions

148g/km

The CO2 emissions of the car, measured in grams per kilometre. A car with less emissions is better for the environment.

3. longer wheelbase

2.85m

The wheelbase is the distance between the center of the front and rear wheels. A longer wheelbase provides the car with more stability and a smoother ride (although a shorter wheelbase can provide more responsive handling).

5. lower ground clearance

122mm

The ground clearance is the distance between the lowest point of the car and the road surface. A shorter ground clearance lowers a vehicle’s center of gravity - increasing its handling ability and reducing the chance of a rollover. However, a higher ground clearance allows you to go over more uneven terrain.
