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
82 × 94.6 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
2998 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
8
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
244 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
11
Maximum power rpm
6250 rpm
Maximum torque N⋅m
500 N⋅m
Maximum torque rpm
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

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

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

2225 kg
Curb weight?
The weight of the vehicle with all standard equipment and fluids but without passengers or cargo. Glossary entry
1805 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
Most driving happens at moderate speeds, so drivers tend to value predictable progress when joining traffic or holding a steady cruise. How an engine and an automatic gearbox are matched usually shapes that impression more than peak figures do.
Drivetrain and Everyday Driving
Familiar controls matter because attention belongs on the road. When climate, audio and wiper functions sit where a driver expects them, adjustments stay brief and routine rather than becoming a search that interrupts concentration during a busy journey.
Body and Practicality
A weekly shop or a couple of suitcases is the usual measure of luggage space. Loading generally feels easier when the boot opening is wide and the load floor sits low enough that heavy bags slide in rather than being lifted.
