Generation photo. Individual trim appearance may differ.
The highest speed a vehicle can sustain under manufacturer test conditions. Some cars are electronically limited below their mechanical potential. Glossary entry
220 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
FWD
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
88 × 68.3 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
2492 cm³
Engine location
Front, transverse
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
4
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
190 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
140 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

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

Engine and Transmission
Most daily driving happens at modest speeds, so what usually matters is predictable behaviour when pulling away and joining traffic. Drivers tend to value consistency across ordinary conditions rather than judging a car by occasional full-throttle use.
Drivetrain and Everyday Driving
Familiar controls matter because attention is limited. When wipers, lights and climate settings can be adjusted without hunting for them, the driver's eyes stay on the road, and short, repeated journeys feel less tiring over time.
Body and Practicality
Loading a weekly shop is a common test of convenience. What generally helps is a boot opening that can be reached without stretching, plus somewhere for bags to sit without sliding around on the way home.
