Remember when their were rumors that the M4 would be powered by a tri turbo six. And one of those turbos would be electric driven!?

Look who will produce a tri turbo four, with one of those turbos being electrically driven!!

The same rumors were going on about the new Porsche 911 Turbo (991) and Subaru WRX(/STI). Nothing happened. Wonder when will the first truly revolutionary turbocharged engine come to market, and by whom?

Whomever makes this cam-less engine into a reality will kick ass in the automotive group... What about taking this Volvo engine and take the cam out in favor of digital technology...

Audi will also have 'e-boosted' engine, which uses a electric motor on the "small" turbo" on their: 3.0-liter V-6 TDI, 385 Hp & 553 ft/lbs, 44 mpg and 0-60mph in 4 secs!! And that is in a RS5.

Audi will probably first put this engine in the new Q7, though.

Thanks Dack... if this tech comes in the next RS5 then you can sign me up, though the new c63 hits my sweet spot lol.

That's neat tech but BMW essentially matches this engine's specs with N57S five years ago and without the electric turbo.

My bet is that BMW will follow up the N57S soon with a 400-425hp B57. Possibly we'll see that for the G11 LCI.

Specs don't tell what the engine's character is. Looking as specs only, there is little difference between tuned N54 and S55.

And Audi's application is only related to TDI engines, not TSI(TFSI). Looking forward to Ferrari's "solution" on the up-coming 458 Italia replacement, or if it is another cheap tuning version of 3.8l V8 Biturbo. Now, you can argue between the differences of 458 Italia and MP4-12C/650S. But what when both will have 3.8l turbocharged V8 engines? How will they really differentiate? What will make you prefer the one over the other, regardless of design or badge?

Today, engine is unfortunately very rarely a reason for which you chose a car. Most decisional factors are other than engine, and even handling, as most almost all cars handle well today.

Character? Of an engine that isn't even in a real product yet? I was sticking to addressing the claimed specs rather than speculating about the feel of an engine that does not even exist right now.

I don't think it's unreasonable to have a small electric compressor to reduce lag. Now, it still takes a ton of power to compress air just half atmosphere at even moderate mass flow rates (thousands or tens of thousands of watts, did the math on this before, it's not pretty), but for a hybrid that's less of a concern since the high power infrastructure is already there. For a non-hybrid, that's a lot of extra current that needs to be controlled and might require a special battery. Either way, there's a lot of engineering in tuning the thing to integrate smoothly with the rest of the engine and exhaust turbine turbos.

Definitely adds complexity and cost...
