Willys Knight Model 20 3.1 MT Specs — First Generation
A door handle that stands proud of the panel sets the real clearance a Willys Knight Model 20 needs, since the widest point is not the bodyside itself.

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
92.1 × 114.3 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
3046 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
4
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
48 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
35 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

Engine and Transmission
Torque is simply a twisting effort about an axis, and effort can be applied to something held still. With the gasoline engine running against a stationary shaft, combustion pressure still loads the crank throw; rotation only follows once that effort exceeds what resists it.
Drivetrain and Everyday Driving
Friction at the contact patch scales with the load pressing the tyre down, so a rear wheel carrying little weight can transmit little drive. Lifting the clutch in this manual gearbox delivers torque the tyre can only use in proportion to that normal force.
Body and Practicality
Front overhang measures forward from the front axle centreline to the bodywork's leading edge, while the axle spacing is measured between the two axles. A sedan can lengthen one without touching the other, since they describe different stretches of the car.
