The highest speed a vehicle can sustain under manufacturer test conditions. Some cars are electronically limited below their mechanical potential. Glossary entry
250 km/h
Engine type
Diesel
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
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
84 x 90 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
2993 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
340 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
250 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
16.5
Maximum power rpm
4400 rpm
Maximum torque N⋅m
700 N⋅m
Maximum torque rpm
1750 rpm
Acceleration to 100?

Engine and Transmission
On a long run, most of the driving happens at a settled cruising speed rather than in bursts. What matters day to day is how relaxed that steady state feels, and how little the drivetrain needs prompting when the road gently rises.
Drivetrain and Everyday Driving
Familiar controls save attention. Over several hours, adjusting climate, wipers or audio by memory keeps your eyes on the road, and a driver who knows where everything sits spends less of the journey hunting for a setting.
Body and Practicality
Luggage on a multi-day trip splits naturally into two groups: cases that stay packed until the destination, and the bag with snacks, chargers and a jacket wanted at every stop. Keeping the second within easy reach avoids unpacking at service stations.
