When it comes to diesel we've taken a more powerful approach.
The 320d engine is supplied with fuel by the distributor pump, which separately supplies each valve via its own delivery pipe, whereas the engines of the 330d, 530d, and X3 3.0sd are supplied with fuel. This employs a high pressure pump to generate the optimum pressure for each phase in the operating cycle, with the pump acting on a common supply line for all injection valves. The common rail system is exceptionally quiet and is the ideal companion to the smooth vibration-free ride offered by an in-line six-cylinder or V8 engine.
BMW diesel engines continue to set new benchmarks for power, torque and responsiveness. They perform with unmatched refinement and outstanding efficiency. With fuel consumption of 4.7 litres per 100 kilometres of driving, the new BMW 118d is the new diesel success story and evidence of the advancement in BMW diesel technology. This class-leading fuel efficiency coupled with 105 kW of power under the bonnet and a maximum torque of 300 Nm is why the new 118d sets new benchmarks for performance within its segment.
The BMW variable Twin Turbo, featured in the X3 3.0sd, X5 3.0sd, 335d and 535d is another BMW innovation that takes the masterful six-cylinder in-line engine to new heights of performance and are amongst the most high-performance diesels in the world today.
All diesels in the current BMW range have emission levels well below EU stipulations; our standard oxidation catalytic converters reduce emissions of hydrocarbons by up to 50 percent, and the emission of particles between 10 and 30 percent.
BMW Group’s strategy for sustainable, clean motoring is called “EfficientDynamics” and is one reason our company has topped the Dow Jones Sustainability Index for the automotive industry two years in a row. EfficientDynamics is a comprehensive programme, not just focussing on powertrain optimisation but also including intelligent in-car energy management measures, lightweight design and ongoing optimisation of aerodynamics. EfficientDynamics has three horizons:
1. Short term - Achieving the most fuel-efficient petrol and diesel engines in all production classes that adhere to the strictest European CO2 emission standards.
2. Mid term - New hybrid technologies that will outperform hybrid vehicles currently available with improved fuel efficiency and battery-recharging technology.
3. Long term - Mass production of a hydrogen powered internal combustion engine, already fitted to a BMW 760Li which is now available for test driving and promotion of ‘Clean Energy’ technology.
The economical efficiency and exceptional performance of the BMW diesel engine are testament to the success of BMW’s EfficientDynamics strategy, delivering sheer driving pleasure combined with class-leading fuel efficiency.
