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 litre N54’s engine power equivalance to a 3.5 litre 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 litre 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 litre V8 engine.

..wooowee….
..there is going to be a lot of E90 doing …vroommm…pisst….vroommm…pisst..(BOV)

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.
can it fit my satria??!!
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?
aksMS: maybe soon. refer to this.

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.
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?
pirate: it's parallel, this post is very old so i've updated it with the new info
