BMW Z4 Roadster sDrive20i (2014): 32 facts and highlights

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.

2. faster top speed

The fastest speed that the car can reach.
250km/h
Bugatti Veyron 16.4 Grand Sport (2013): 414km/h

3. more cylinders

Although there are many aspects that determine the power, a higher number of cylinders is generally a good indication of the potential power of the engine.
6
Bugatti Veyron 16.4 Grand Sport (2013): 16

4. faster acceleration (0-100)

The time it takes for the car to accelerate from 0-100 kilometres per hour.
5.2s
Bugatti Veyron 16.4 Grand Sport (2013): 2.5s

5. better fuel economy (highway)

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.
7.1l/100 km
Ferrari 458 Spider (2013): 0l/100 km

6. Has Bluetooth

Bluetooth is a wireless technology that allows you to easily transfer data between different devices, such as smartphones, tablets and computers.

7. better fuel economy (combined)

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.
9.4l/100 km
Porsche 918 Spyder (2015): 3.1l/100 km

8. more valves

An intake valve allows the air/fuel mixture to enter the combustion chamber. An engine with more valves tends to increase performance.

Bugatti Veyron 16.4 Grand Sport (2013): 64

9. more horsepower

Horsepower is the most common unit for measuring the power of an engine.
306hp
Bugatti Veyron 16.4 Grand Sport (2013): 1001hp

10. higher maximum torque

Torque is a measurement of an engine’s power, closely related to horsepower. More torque indicates a more powerful car, and is also a good indication of its acceleration.
400Nm
Bugatti Veyron 16.4 Grand Sport (2013): 1250Nm

11. less CO2 emissions

The CO2 emissions of the car, measured in grams per kilometre. A car with less emissions is better for the environment.
219g/km
Porsche 918 Spyder (2015): 72g/km

12. larger fuel tank

A larger fuel tank means that you have to stop to refill less often.
55l
Bugatti Veyron 16.4 Grand Sport (2013): 100l

13. 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.

14. Has a petrol (gasoline) engine

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.

15. shorter length

4.24m
Smart Passion Cabriolet (2014): 2.65m

16. longer wheelbase

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).
2.5m
Rolls-Royce Phantom Drophead Coupe (2014): 3.32m

17. 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.
13.4l/100 km
Ferrari 458 Spider (2013): 0l/100 km

18. width

1.95m
Nissan Murano CrossCabriolet (2014): 1.21m

19. 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
Bugatti Veyron 16.4 Grand Sport (2013): 8l

20. 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.

21. lower coefficient of drag

The coefficient of drag is one measurement of how well air travels around a vehicle. A lower value means it is more aerodynamic and the engine doesn't have to work as hard. It can result in faster speeds and lower fuel economy.
0.35Cd
Lexus IS 250C (2014): 0.29Cd

22. greater cargo volume

A larger cargo area is more practical as it allows you to transport more things.
227l
Nissan Murano CrossCabriolet (2014): 3448l

23. smaller turn radius

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.
10.7m
Smart Passion Cabriolet (2014): 8.4m

24. Has fully independent suspension

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

25. longer basic warranty (years)

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.
4yrs
Ferrari California T (2014): 7yrs
