Current Formula One engines have six cylinders, arranged as a turbocharged 1.6-litre V6. The V6 internal-combustion configuration has been central to F1 power units since the 2014 regulations and remains in place under the 2026 engine rules.
The phrase “engine” is often used loosely because modern F1 cars use complete hybrid power units. Alongside the six-cylinder internal-combustion engine, the system includes a turbocharger, an MGU-K electric motor, an energy store, control electronics and an exhaust system. From 2014 through 2025, it also included an MGU-H heat-recovery motor; that component was removed for 2026.
Older Formula One eras used different cylinder counts, which explains many quiz mistakes. V10 engines were prominent from 2000 to 2005, while V8 engines powered the sport from 2006 to 2013. The six-cylinder hybrid era began in 2014, combining exceptional performance with energy recovery and tighter fuel limits.
Despite the smaller displacement, a modern power unit can produce around 1,000 horsepower when its electrical and combustion systems work together.
