With an engine block small enough to fit in the overhead luggage compartment of an airplane, the 1.0-liter features a cylinder head with an integrated and cooled exhaust manifold that lowers exhaust temperatures for optimizing the fuel-to-air ratio. An innovative flywheel and front pulley design delivers improved refinement, while a compact, low-inertia turbocharger spins at up to 248,000 rpm—more than 4,000 times per second and almost twice the maximum rpm of the turbochargers used in the 2014 Formula One World Championship.
