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.

That low-end torque is monumental, especially from a turbocharged engine! I'd love to see it in a non-M 3 series.

I'm looking forward to the fuel figures. I drove my 2nd cousins 335ci around and could easily get 30mpg highway cruising 65-70ish. I always love trying to get 400+ miles out of a 16 gallon tank when I am driving around Atlanta highways and the burbs

look at the air intake??? Goes from right side of engine, back to firewall, over top of engine and down to turbo. Must be 6 feet long, not to mention the enormous air box BMW is sure to put on it
