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 × 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
1995 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
6
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
177 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
130 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
With the listed automatic, the driver sets throttle and brake while the gearbox chooses ratios. Steptronic adds a manual gate, so gear selection can be taken over by nudging the lever when a held ratio is preferred over the automatic's own choice.
Drivetrain and Everyday Driving
Rear-wheel drive separates the jobs: the front wheels only steer, while the rear wheels deliver the diesel's torque. Steering effort therefore stays free of the tugging that arises when one axle handles both tasks under load.
Body and Practicality
A three-door hatchback puts rear-seat access through the front door openings, so the front backrests tilt and slide forward to clear a path. The tailgate itself opens the luggage area and cabin together as one loading space.
