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
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
85 × 73.3 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
2496 cm³

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
7
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
222 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
163 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
A five-door SUV body sits fairly high, so gearing matters. A transmission ratio multiplies torque at the wheels by trading rotational speed for turning effort; the engine still produces the same power, and the gearbox only divides it differently.
Drivetrain and Everyday Driving
An automatic gearbox chooses its own moment to engage and release drive, so torque can arrive while the driver is steering. Tyres with worn tread or uneven pressures translate that into slip rather than motion, even at gentle speeds.
Body and Practicality
Luggage volume is measured as though the space could be filled completely, but rigid items cannot bend around wheel arches or a sloping backrest. A long or boxy object may need seats folded even when the quoted space seems ample.
