The previous M54/M56 engine is being replaced with a new engine variant referred to as the N52, which introduces a number of new technologies with regard to engine development.
The objectives in developing the N52 include:
- Increased power output and torque
- Reduction of fuel consumption
- Reduction of overall engine weight
- Top position in engine class through efficient dynamics
- Utilization of innovations for customer benefit
By implementing some of the latest technology into the N52 engine, BMW met the objectives by improving the power to weight ratio, reduced emissions and decreased fuel consumption.
