BMW Z4 Roadster sDrive20i (2014) vs Bugatti Veyron 16.4 Grand Sport (2013): 30 facts in comparison

1. Has dual-clutch transmission

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.

10. larger fuel tank

A larger fuel tank means that you have to stop to refill less often.
55l
Ford Super Duty F-250 XL (2015): 132l
100l

11. Has rear-wheel drive

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.

16. better fuel economy (city)

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.
8.9l/100 km
Ferrari 458 Spider (2013): 0l/100 km
41.9l/100 km

17. larger engine size

This measurement is the total volume of all the engine's cylinders, also known as the engine displacement. This is one of many aspects of an engine that determine its horsepower, but generally speaking a greater size indicates more power.
3l
SRT Viper (2014): 8.4l
8l

18. Has a turbocharged engine

A turbocharger compresses the air entering the cylinders, allowing more air (and therefore more fuel) to be added - resulting in a more powerful explosion. This leads to an increase in horsepower without increasing the size and weight of the engine.
