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

Not provided
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

104.71 × 95 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

6555 cm³
Engine location
Not provided
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

3
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

325 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

239 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

Not provided
Maximum power rpm
Not provided
Maximum torque N⋅m
Not provided
Maximum torque rpm
Not provided
Acceleration to 100
?

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

Not provided
Engine power system
Carburetor
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

2
Cylinder arrangement
V-shaped
Maximum power ICE

Battery power
Not provided
Fuel grade
Not provided
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

Not provided

Not provided
Power consumption
Not provided
Fuel tank capacity

Full public charging time
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

Coupe
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

1524 mm

Not provided
Trunk volume min
Not provided
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

1499 mm
Max weight
Not provided
Curb weight
?

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

Not provided
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

Engine and Transmission

For longer journeys, a priority is smooth and predictable acceleration when merging or maintaining pace on open roads. Having enough response to keep up with traffic without constant gear changes makes the drive less tiring, whatever the engine or transmission setup.

Drivetrain and Everyday Driving

Familiar controls reduce distraction on longer journeys. When switches and stalks are where you expect them, adjusting ventilation or audio doesn't take your attention away from the road for more than a moment.

Body and Practicality

Passengers often carry a few personal items they want within reach, like a phone or a water bottle. Convenient storage spots near the seats help keep the cabin tidy and reduce the need to stop and search through bags.
