Performance & powertrain

Top speed
?

The highest speed a vehicle can sustain under manufacturer test conditions. Some cars are electronically limited below their mechanical potential. Glossary entry

210 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

83 × 99 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

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

16.2
Maximum power rpm
3800 rpm
Maximum torque N⋅m
500 N⋅m
Maximum torque rpm
1600 – 1800 rpm
Acceleration to 100
?

The time a vehicle needs to reach 100 km/h from a standstill, a common shorthand for overall performance. Glossary entry

9 s
Engine power system
Not provided
Number of cylinders
4
Valves per cylinder
?

The number of intake and exhaust valves in each cylinder. Four valves per cylinder is common and helps the engine breathe at higher speeds. Glossary entry

Fuel grade
Diesel
Mild Hybrid
?

A car with a small electric motor and battery that assist the combustion engine and recover braking energy but cannot drive on electricity alone. Glossary entry

Not provided
Battery type
Not provided
CO2 emissions
?

The amount of carbon dioxide released per kilometre under a standardised test. Lower figures usually go hand in hand with lower fuel consumption. Glossary entry

Driving range, maximum
?

The distance an electric or plug-in vehicle can travel on a full charge under a stated test cycle. Temperature, speed and load change the real result. Glossary entry

Not provided
Driving range, minimum

Not provided means the source has no value. Zero remains zero. Units are shown as supplied; range test cycles are only stated when known.

Estimates use only the figures you enter, in your own currency. No live fuel prices or emissions data are used.

Comfort and Convenience

Preferred seating position is personal. Leg length, arm reach and the angle people find restful all differ, so the setup one driver settles on quickly can feel wrong to the next person who takes the wheel.

Safety and Driver Assistance

A few minutes parked, spent locating lights, wipers, the hazard switch and demisting, counts as preparation rather than something left until later. Searching for an unfamiliar control is always harder once the car is moving in traffic.

Multimedia and Connectivity

Keeping a phone charged matters on longer days out. Where a charging point is provided, the useful detail is how the cable runs, so the phone stays put and nothing is left trailing across the controls.
