Mercedes R-Class 3.0 AT Specs — First Generation Restyling

The Mercedes R-Class 3.0 AT, from the first generation restyling, is a diesel people carrier whose rear-wheel-drive layout shapes how its automatic gearbox handles both low-speed manoeuvring and steady main-road travel.

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

215 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

83 × 92 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

2987 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

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

15.5
Maximum power rpm
3800 rpm
Maximum torque N⋅m
440 N⋅m
Maximum torque rpm
1400 – 2800 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

9.5 s
Engine power system
Not provided
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

Cylinder arrangement
V-shaped

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

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

Trunk volume min
1118 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

Curb weight
?

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

2185 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

Moving off asks the transmission to multiply engine torque heavily, since a stationary vehicle resists motion; once rolling, that same multiplication would leave the engine spinning needlessly fast, so taller ratios trade pulling effort for quieter, more economical cruising.

Drivetrain and Everyday Driving

Under acceleration, weight transfers rearward and presses down on the back tyres. In a rear-wheel-drive layout those loaded tyres are also the driven ones, so the forces of propulsion and steering are handled at separate axles rather than sharing one contact patch.

Body and Practicality

Luggage volume is measured as though cargo were pourable, but real items are rigid. A tall box or a long pushchair needs a matching dimension between the wheel arches or under the roofline, so usable space depends on shape as much as on the stated total.
