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

200 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

FWD
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

77 × 85.8 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

1598 cm³
Engine location
Front, transverse
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

150 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

110 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

10.5
Maximum power rpm
6000 rpm
Maximum torque N⋅m
240 N⋅m
Maximum torque rpm
1400 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

9.3 s
Engine power system
Direct injection (direct)
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

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

Wheelbase
?

The distance between the centres of the front and rear wheels. A longer wheelbase usually gives more cabin space and a calmer ride; a shorter one helps agility and parking. Glossary entry

Rear track width
?

The distance between the centres of the two wheels on the same axle. A wider track generally improves stability in corners. Glossary entry

440 l
Front track width
?

The distance between the centres of the two wheels on the same axle. A wider track generally improves stability in corners. Glossary entry

1525 mm
Max weight
1835 kg
Curb weight
?

The weight of the vehicle with all standard equipment and fluids but without passengers or cargo. Glossary entry

1390 kg
Ground clearance, maximum
?

The gap between the lowest point of the underbody and the road. More clearance helps on rough roads and steep driveway ramps. Glossary entry

Not provided
Ground clearance, 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.

Fuel cost calculator

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

Comfort and Convenience

During travel the listed on-board computer draws on fuel-flow and distance sensors to report consumption and remaining range, so refuelling decisions on a route rest on measured data rather than the fuel gauge alone.

Safety and Driver Assistance

Side front airbags sit in the seat backrests and deploy from crash sensors, not from steering or braking inputs. They inflate between the occupant's torso and the door structure in a side impact.

Multimedia and Connectivity

The 12V outlet carries direct-current electrical power rather than audio or data signals. An adapter converts it to the lower voltage a phone or dashcam charger needs; the audio system handles sound separately.
