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
Not provided
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
2143 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
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
204 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
150 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
When the automatic selects a higher ratio, engine speed drops for the same road speed because each turn of the crankshaft covers more distance at the rear wheels. Downshifting reverses this, lifting revs to restore pulling effort.
Drivetrain and Everyday Driving
With rear-wheel drive, the back tyres handle propulsion while the front ones steer. Adding throttle mid-corner asks the rear tyres to deliver drive and cornering grip at once, and their total grip must cover both demands.
Body and Practicality
A label such as Sedan Long describes the body's shape and its extended wheelbase, not how the interior is divided. Seat count, individual rear chairs or a bench are separate specifications that vary within one body style.
