Which Car Engine Is Most Powerful?
The most powerful car engine ever produced is the Rolls-Royce Merlin V16, which was used in the Supermarine Spitfire and other British aircraft during World War II. The Merlin V16 had a displacement of 27 litres and produced over 2,000 horsepower.
In terms of modern production cars, the most powerful engine is the Bugatti Chiron’s 8.0-liter W16, which produces 1,500 horsepower and 1,180 lb-ft of torque. The Chiron can accelerate from 0 to 60 mph in 2.4 seconds and has a top speed of 261 mph.

- Porsche 911 Turbo S’s 3.8-liter twin-turbocharged flat-six: 580 horsepower, 553 lb-ft of torque
Factors That Affect Horsepower
The horsepower of a car engine is determined by a number of factors, including:
- Displacement: The displacement of an engine is the volume of air and fuel that can be moved by the pistons in a single cycle. The larger the displacement, the more horsepower an engine can produce.
- Number of cylinders: The number of cylinders in an engine also affects its horsepower. More cylinders mean more power, but they also mean more weight and complexity.
- Compression ratio: The compression ratio is the ratio of the volume of the cylinder when the piston is at the bottom of its stroke to the volume of the cylinder when the piston is at the top of its stroke. A higher compression ratio means more power, but it also means that the engine is more likely to knock.
- Turbochargers and superchargers: Turbochargers and superchargers are devices that force more air into the engine, which can increase horsepower. Turbochargers use the exhaust gases from the engine to spin a turbine, which in turn drives a compressor that forces more air into the engine. Superchargers are driven by the engine’s crankshaft, which means that they can provide more boost at low engine speeds.
