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

No
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

98 × 90.5 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

5461 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

421 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

310 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

12.6
Maximum power rpm
6800 rpm
Maximum torque N⋅m
540 N⋅m
Maximum torque rpm
4500 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

4.6 s
Engine power system
Direct injection (direct)
Number of cylinders
8
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

Cylinder arrangement
V-shaped

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

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

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

Trunk volume min
225 l
Front 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

Max weight
1910 kg
Curb weight
?

The weight of the vehicle with all standard equipment and fluids but without passengers or cargo. Glossary entry

1610 kg
Ground clearance, maximum
?

The gap between the lowest point of the underbody and the road. More clearance helps on rough roads and steep driveway ramps. Glossary entry

Not provided
Ground clearance, minimum
?

The gap between the lowest point of the underbody and the road. More clearance helps on rough roads and steep driveway ramps. Glossary entry

Not provided means the source has no value. Zero remains zero. Units are shown as supplied; range test cycles are only stated when known.

Fuel cost calculator

Estimates use only the figures you enter, in your own currency. No live fuel prices or emissions data are used.

Comfort and Convenience

Paddle shifters let the driver call for a gear change from the wheel rim without moving a hand to the lever. They govern ratio choice only; cabin temperature stays with the single-zone climate control.

Safety and Driver Assistance

On an uphill stop, a car rolls backwards in the moment between brake and throttle. Hill start assist briefly holds brake pressure to cover that handover, then releases; it does not hold the car parked.

Multimedia and Connectivity

Bluetooth links a phone wirelessly for calls and streamed audio, handling pairing and connection automatically. The AUX audio input instead carries a plain cable signal from any device with a headphone socket, whatever it plays.
