Since the 2019 season, the car has been powered by a newly developed four-cylinder inline engine with a displacement of two liters, a turbocharger, and direct gasoline injection.[2] Thanks to supercharging, the BMW P48 achieves an output that is about 100 kW higher—with half as many cylinders as the previous engine and half the displacement—reaching approximately 456 kW (620 hp).[14] The intakes in the hood were significantly enlarged for intercooling.[2] The engine weighs just 85 kg and operates at boost pressures of up to 2.5 bar, which corresponds to 400 liters of air per second. It can reach speeds of up to 9,500 rpm.[15] The engine block and cylinder head are made of cast aluminum and are manufactured using the sand casting process. The crankshaft and camshafts are made of steel.[16] The friction-optimized engine does not require fuel-cooled parts and outperforms the 8-cylinder engine by 10 percent in terms of efficiency; compared to the first turbo engine in the BMW 02, which had a boost pressure of up to 1.76 bar, it outperforms it by 50 percent.
