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

108 × 85.7 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

6277 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

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

324 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

238 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
Maximum power rpm
4600 rpm
Maximum torque N⋅m
570 N⋅m
Maximum torque rpm
2800 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

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

Fuel grade
92
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

Fuel tank capacity
76 l
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

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

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
Not provided
Curb weight
?

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

1830 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

Engine and Transmission

At a steady pace the automatic settles into its highest available ratio, letting the engine turn slowly. Press further and the transmission downshifts, trading that relaxed gearing for a lower ratio that multiplies torque until the driver eases off again.

Drivetrain and Everyday Driving

Rear-wheel drive only describes which axle receives power through the transmission; it says nothing about what sits inside that axle. An open, limited-slip or locking differential can all serve the same layout, and only a specification entry confirms which is fitted.

Body and Practicality

A hardtop sedan omits the fixed frame around the door glass, so with the windows lowered the side opening is largely clear. Exterior length and width describe the car's footprint, not how much the driver actually sees through the glazed area.
