The Mercury Topaz 3.0 AT is a second-generation front-wheel-drive sedan. One useful starting point is what the neutral position of its automatic transmission actually does mechanically.

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
FWD
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
89 × 80 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
2986 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
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
137 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
101 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

Acceleration to 100?
The time a vehicle needs to reach 100 km/h from a standstill, a common shorthand for overall performance. Glossary entry
10.6 s

Engine and Transmission
In an automatic, neutral disengages the clutches that link the engine to the output shaft, so the front wheels are no longer tied to the crankshaft. The engine can idle while the car is pushed or towed a short distance.
Drivetrain and Everyday Driving
Which axle receives torque says nothing about how far the front wheels can pivot. Steering angle is set by rack travel and by clearance between tyre, suspension and bodywork, and the turning circle follows from that geometry.
Body and Practicality
Exterior length and width describe the space a sedan occupies, while the view out depends on glass area, pillar thickness and the height of the beltline. A long car with deep windows can feel easier to place than a short one with shallow glazing.
