Performance & powertrain

Top speed
?

The highest speed a vehicle can sustain under manufacturer test conditions. Some cars are electronically limited below their mechanical potential. Glossary entry

250 km/h
Engine type
Gasoline
Transmission
Automatic
Type of boost
?

A turbocharger or supercharger compresses the air entering the engine so a smaller engine can produce more power. Naturally aspirated engines draw air without a compressor. Glossary entry

Turbo
Type of drive
?

Which wheels receive power: front-wheel drive, rear-wheel drive or all-wheel drive. All-wheel drive can send power to every wheel for extra traction. Glossary entry

RWD
Bore and stroke
?

The diameter of a cylinder (bore) and the distance the piston travels inside it (stroke). Together they determine the displacement of the engine. Glossary entry

92.9 × 86 mm
Engine capacity
?

The total volume swept by all pistons inside the cylinders, usually stated in cubic centimetres or litres. Larger displacement often means more power but higher consumption. Glossary entry

2996 cm³
Engine location
Front, longitudinal
Number of gears
?

How many fixed forward ratios a gearbox offers. More gears can improve economy and refinement; continuously variable transmissions have no fixed steps. Glossary entry

7
Maximum power
?

A unit of engine or motor output. One metric horsepower is about 0.735 kilowatts. Peak power is normally reached at high engine speed. Glossary entry

333 hp
Maximum power, kw
?

A unit of engine or motor output. One metric horsepower is about 0.735 kilowatts. Peak power is normally reached at high engine speed. Glossary entry

245 kW
Compression ratio
?

The ratio between the largest and smallest volume of a cylinder as the piston moves. Higher ratios improve efficiency but may require higher-octane fuel. Glossary entry

10.5
Maximum power rpm
5250 – 6000 rpm
Maximum torque N⋅m
480 N⋅m
Maximum torque rpm
1600 – 4000 rpm
Acceleration to 100
?

The time a vehicle needs to reach 100 km/h from a standstill, a common shorthand for overall performance. Glossary entry

5.2 s
Engine power system
Direct injection (direct)
Number of cylinders
6
Valves per cylinder
?

The number of intake and exhaust valves in each cylinder. Four valves per cylinder is common and helps the engine breathe at higher speeds. Glossary entry

4
Cylinder arrangement
V-shaped

Battery power
Not provided
Fuel grade
95
Mild Hybrid
?

A car with a small electric motor and battery that assist the combustion engine and recover braking energy but cannot drive on electricity alone. Glossary entry

Not provided
Battery type
Not provided
CO2 emissions
?

The amount of carbon dioxide released per kilometre under a standardised test. Lower figures usually go hand in hand with lower fuel consumption. Glossary entry

179 g/km

Not provided
Driving range, maximum
?

The distance an electric or plug-in vehicle can travel on a full charge under a stated test cycle. Temperature, speed and load change the real result. Glossary entry

Not provided
Driving range, minimum
?

The distance an electric or plug-in vehicle can travel on a full charge under a stated test cycle. Temperature, speed and load change the real result. Glossary entry

Wheelbase
?

The distance between the centres of the front and rear wheels. A longer wheelbase usually gives more cabin space and a calmer ride; a shorter one helps agility and parking. Glossary entry

Drop-top
Rear track width
?

The distance between the centres of the two wheels on the same axle. A wider track generally improves stability in corners. Glossary entry

Comfort and Convenience

How often to stop for a drink or snack differs between people, because some like frequent short pauses while others prefer one longer break at a planned stop.

Safety and Driver Assistance

Finding the indicator stalk and the fan switch before leaving the driveway means those actions can be done from memory once the journey is under way.

Multimedia and Connectivity

If a call needs to be made, waiting until a fuel stop leaves the phone as a standing-still task. A missed ring can be returned then, once the car is quiet.
