The highest speed a vehicle can sustain under manufacturer test conditions. Some cars are electronically limited below their mechanical potential. Glossary entry
301 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
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
84 × 89.6 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
2979 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
8
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
410 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
301 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 town a car spends much of its time at low speed, edging forward in queues and pulling away from lights. Drivers tend to value predictable behaviour in that range, since the same few metres are repeated many times each journey.
Drivetrain and Everyday Driving
Urban driving asks for attention outward: junctions, cyclists, changing signals. Controls a driver already knows by feel can be adjusted with a glance or none at all, keeping the pause between intention and action short.
Body and Practicality
Shopping brought back from town rarely travels as one neat block; bags settle, slide and tip during turns. What makes that easy is somewhere to load from the kerb and a habit of packing heavier items low and towards the back.
