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
AWD
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 x 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
374 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
275 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

Engine and Transmission
Much everyday driving happens in traffic queues and on slip roads, where passengers appreciate gentle transitions between speeds. Anticipating gaps early, rather than reacting late, usually keeps heads still and stops anyone feeling thrown about.
Drivetrain and Everyday Driving
Passengers often ask for small changes: more warmth, less noise, a different route. Handling those requests without hunting through unfamiliar menus keeps eyes up and the journey relaxed, which matters most at night or in unfamiliar towns.
Body and Practicality
Everyone brings something small aboard, such as a phone, a bottle or a pair of sunglasses. Journeys feel tidier when each person has somewhere obvious to put those items, so nothing slides into a footwell and needs retrieving later.
