Travelling with passengers changes how a car is judged. This overview looks at the BMW Z4 M 3.3 MT through that everyday lens, covering shared-space habits rather than the figures shown on the accompanying cards.
1 generation · Roadster
Generation photo. Individual trim appearance may differ.
The highest speed a vehicle can sustain under manufacturer test conditions. Some cars are electronically limited below their mechanical potential. Glossary entry
250 km/h
Engine type
Gasoline
Transmission
Manual
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
No
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
91 × 87 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
3246 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
343 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
252 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
11.5
Maximum power rpm
7900 rpm
Maximum torque N⋅m
365 N⋅m
Maximum torque rpm
4900 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
5 s
Engine power system
Distributed injection (multi-point)
Number of cylinders
6
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

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

Curb weight?
The weight of the vehicle with all standard equipment and fluids but without passengers or cargo. Glossary entry
1415 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

Engine and Transmission
With company aboard, the priority often shifts from outright pace towards predictability. Passengers cannot anticipate throttle or gear changes the way a driver does, so unhurried inputs and steady progress in traffic generally make a journey more agreeable for everyone.
Drivetrain and Everyday Driving
Familiar controls matter because attention is limited, and conversation inside the cabin competes for it. When wipers, lights or climate adjustments can be made by habit, the driver spends less time searching and more time watching the road ahead.
Body and Practicality
Loading is often the awkward part of a shared trip. Soft, compressible bags usually suit a luggage area better than rigid cases, and deciding before departure what must stay within reach saves reopening everything again at every stop.
