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

232 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

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

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

190 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

140 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
4000 rpm
Maximum torque N⋅m
400 N⋅m
Maximum torque rpm
1750 – 2500 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

7.1 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

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
?

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

Comfort and Convenience

Seating position is a personal preference: some drivers want to sit high with a clear view forward, others prefer a lower, more enclosed posture. Height, build and habit all pull in different directions, so no single setting suits everyone.

Safety and Driver Assistance

Sorting out mirrors, lights, wipers and heating before setting off takes a moment in a parked car and removes the need to hunt for them later. Preparation is simply doing the easy part while nothing else is happening.

Multimedia and Connectivity

Short trips rarely restore much battery, so if charging is available on board it is best treated as topping up rather than a full recharge. Calls and music are separate needs and may rely on different arrangements.
