The first-generation Buick Limited 6.0 AT is a rear-driven convertible, and the way its power reaches the road from behind the cabin shapes much of how the car behaves.

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
Not provided
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
5972 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
279 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
205 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
Gasoline burns only as a vapour mixed with air, so the induction system must atomise liquid fuel before the spark arrives. The rising piston compresses that mixture, and the flame front's expansion pushes it back down, turning heat into rotation sent rearward.
Drivetrain and Everyday Driving
An automatic applies torque through a fluid coupling rather than an abrupt clutch release, so load builds progressively. As the car accelerates, weight shifts rearward onto the driven wheels, pressing those contact patches down while the front tyres carry less.
Body and Practicality
A luggage opening sets only the largest cross-section that can pass through it. Depth is a separate matter: on a cabrio the lid is often shallow and set low, so the far end must be reached by sliding items in rather than lowering them.
