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.
