F1 cars are hybrids and it has become a fuel economy competition. They use a motor/ generator on the crank and another on the turbo that can alternately harvest energy from the exhaust and act as the variation to control boost pressure. Or provide supercharging boost until the exhaust flow comes back up during first acceleration.
