The N54 features a twin-turbocharging system, as well as direct-fuel injection and BMW’s own Valvetronic technology, and in its most potent configuration develops up to 326hp (243kW) at 5,800rpm and 332lb-ft (450Nm) of torque from as low as 1,500rpm. BMW’s new variation on the engine, labeled the N55, is based on the same basic engine block and valve system but only sports a single turbocharger. It is the world’s first engine to combine turbocharging, direct fuel injection and fully variable Valvetronic valve management developed by BMW.

Peak output is still a healthy 306hp (225kW) at 5,800rpm and 295lb-ft (400Nm) of torque from an even lower 1,200rpm. Furthermore, the new N55 is also said to be more fuel-efficient than the N54 though no independent test results have been produced.
