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

295 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

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

Not provided
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

3982 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

9
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

476 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

350 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

8.6
Maximum power rpm
5500-6500 rpm
Maximum torque N⋅m
700 N⋅m
Maximum torque rpm
2250-4500 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

3.9 s
Engine power system
Not provided
Number of cylinders
8
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

Comfort and Convenience

Seating position preferences differ because bodies and habits do. Height, leg length and how upright someone likes to sit all shape a chosen setup, so two people often settle on quite different arrangements.

Safety and Driver Assistance

A few minutes with the basics before setting off pays off: lights, wipers, mirrors and the hazard switch are simply easier to locate while parked than to hunt for once traffic is moving.

Multimedia and Connectivity

Charging deserves separate thought from listening. A phone used for hours needs power somewhere convenient, calls depend on audio that stays clear, and if music matters most, straightforward track control counts.
