MODIFICATION

Toyota Crown 2.3 AT Specs — Fourth Generation

Much of the Crown's exterior length sits ahead of and behind the cabin, so overall body measurements say little about the space occupants actually sit in.

4 generation · Coupe Hardtop

1971–1974

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

Not provided
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

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

85 × 75 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

2253 cm³
Engine location
Not provided
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

3
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

115 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

86 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

Not provided
Maximum power rpm
5200 rpm
Maximum torque N⋅m
172 N⋅m
Maximum torque rpm
3600 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

Not provided
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

2

Energy & emissions

ECO class

Fuel grade
Not provided
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
?

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

2690 mm
U-turn diameter

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
Not provided
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

Not provided
Max weight
Not provided
Curb weight
?

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

1290 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

Engine and Transmission

A gasoline engine's oil does its work by clinging to metal: the moving surface drags the fluid along with it, and because the film is sheared rather than broken, the load rides on that moving layer instead of on the metal beneath it.

Drivetrain and Everyday Driving

Rear-wheel drive is a routing decision — torque is sent to the back axle — while alignment is a set of angles that can drift out of specification on any layout after kerb strikes or wear. The automatic gearbox affects neither.

Body and Practicality

Through a coupe hardtop's door opening, a boxed item stops being a simple rectangle once a handle juts out: the aperture must admit the handle's arc as the box is angled in, so the useful measurement is taken across that projection.
