BMW N54 Bi-Turbo Engine
After testing their new turbocharged petrol engine on a modified BMW 5-series, BMW has officially announced their new turbocharged petrol engine, the N54 Bi-Turbo.
The BMW N54 Bi-Turbo is expected to be installed for the first time ever in the 2007 BMW 335i E90 sedan and the 2007 BMW 335ci E92 coupe. It uses 2 turbochargers, fed by 3 cylinders each in parallel arrangement to reduce turbo lag. The new cars that carry this engine will have the 335 insignia, which represents the 3.0 liter N54’s engine power equivalance to a 3.5 liter normally aspirated engine.
Performance stats are quoted to be 306hp and 400Nm of torque. Previous horsepower stimated figure was 330hp. As a comparison, the 3.0 liter normally aspirated inline-6 engine in the 330i makes around 260 horsepower. Also, the new N54 Bi-Turbo engine is 70kg lighter than BMW’s 4.0 liter V8 engine.

i think this is the same technology they apply on last year 5 series diesel. they claimed this is one of the fastest diesel car in the world as i remember.

Considering that this engine is a petrol version and is equipped with a small and large turbocharger running sequentially, peak torque should be really good .
The E90 330I N52 B30A engine was already one of the best 6 cylinder engines money can buy. This new N54 Bi-Turbo should be very interesting.

BMW has always been trying to produce a fast diesel engine. If I’m not mistaken, Ralf Schumacher was once caught speeding (220km/h+) by German traffic warden in his 530id and it’s and Estate (wagon)! And he said BMW should pay him for the “advertisement”.
Just when will we ever get to hear Campro diesel?

Paul,
Yeah, I read that one. The question is when? And if it’s really happening, I do hope Proton negotiated for the latest technology. Not the 1st or 2nd generation. Too expensive? Get the parts quality right, I don’t think the consumer will complain much about the price.

[...] While BMW toils to prepare it’s new 4.0 liter V8 engine for the new BMW M3, Hartge has injected some well needed horsepower into the new BMW E90 3-series. Feeling that the top of the line 3 liter in-line 6 and the upcoming 3 liter turbocharged in-line 6 is inadequate, they’ve somehow managed to take the Formula 1 inspired 5.0 liter V10 engine from the E60 BMW M5 and stuffed it into the E90’s engine bay, lock, stock, transmission and barrel. Not feeling satisfied with the 504 horses that it already has, it performed some extra tweaking to it. Hartge’s engineers managed to extract 550bhp, about 46 horses extra from the standard engine. Maximum torque remains at 520 Nm. [...]

[...] BMW’s latest 3-series coupe, the E92 was chosen as a platform for BMW to introduce to us their latest engine, the award-winning twin-turbocharged N54 3.0 liter straight-six. Although I have not test driven the car yet, Jeremy Mahadevan shares with us his experience driving the new BMW 335i Coupe in Austria. [...]

I read somewhere else that this N54’s bi-turbo is actually in a non-sequential arrangement. Each bank of 3-cylinders gets a smallish turbocharger instead of one BIG turbine or twin turbines feeding all of the 6 combustion chambers…
Now: which is true, Paul?

[...] AUTOMEDIA has spy shots of a BMW 1-series being tested on the track, with a camouflage bumper that reveals an intercooler. This would mean BMW is planning to put the new twin turbo N54 gasoline engine into the little 1-Series, turning it into a seriously HOT hatchback. The car might be called the 135i or the 135ti, with the t indicating the twin turbochargers under the hood. Over 300bhp in this little hatch would mean it has a more than 50 horses advantage over it’s competition like the Volkswagen Golf R32 which makes about 250 horsepower, though that’s due to be upped to a 3.6 liter V6 soon.
