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
Compressor
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
96.5 × 86.4 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
3791 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
225 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
165 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
In this gasoline sedan, the automatic transmission uses a fluid coupling between engine and gearbox, so crankshaft rotation is passed on through moving oil rather than a driver-held clutch. That lets the engine keep turning while the car stands still.
Drivetrain and Everyday Driving
Front-wheel drive decides which wheels receive that torque, while alignment describes the angles at which the wheels sit relative to the road. One is a layout choice; the other is a serviceable setting that can drift after kerb strikes.
Body and Practicality
A sedan's boot sits behind the rear glass as a separate closed volume, so the outline ends well past the back seats. When parking, the reference point for the rear is that hidden tail, not the visible rear window.
