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
107.98 × 101.6 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
7443 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
248 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
182 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
Drivers usually weigh two everyday priorities: easy progress through slow town traffic, and calm, low-effort cruising on open roads. Which matters more tends to depend on the routes covered most often rather than on any single specification.
Drivetrain and Everyday Driving
Familiar controls matter because attention spent hunting for a switch is attention taken from the road. Once wipers, lights and mirror adjusters have been located calmly while parked, using them mid-journey becomes almost automatic.
Body and Practicality
A weekly shop is simplest when bags can be set down on a flat surface rather than lifted over an obstruction. In general, load height and floor shape decide how much bending and lifting the task involves.
