High Precision Injection
In this cutting-edge generation of petrol direct injection, the Piezo injectors are positioned very close to the spark plugs. They inject the fuel at high pressure and with extreme precision. The injectors’ central positioning means only part of the combustion chamber needs to be filled with an ignitable petrol-air mixture. The engine can then run “leanly” and so efficiently,precisely in the heavily used moderate load range. (520i, 523i, 525i, 530i)
Shift Point Display
Timely gear shifts are one of the most effective and easiest ways to save fuel. This is where Shift Point Display in conjunction with 6-speed manual transmission comes in. It shows the driver what gear to use in order to save fuel. (520i, 523i, 525i, 530i, 540i, 550i, 520d,525d, 530d)
Air vent control
Engine management signals the engine’s current cooling capacity requirements constantly while driving. Rendering a permanent airstream through the radiator unnecessary. The air vents in front of the radiator open or close depending on the environmental temperature and road speed. When shut they improve aerodynamics, shorten the engine’s warm-up time and so reduce fuel consumption. (all models)
Tyres with reduced rolling-resistance
While driving, tyres are constantly changing shape. This uses up energy and thus fuel. Tyres with reduced rolling-resistance have an improved design and use special materials for their road treads and side walls, thus reducing deformation. (520i, 523i, 525i, 520d, 525d)
Brake Energy Regeneration
To supply a battery with electrical energy,the generator (alternator) is customarily driven using engine power, which demands permanent fuel consumption. Brake Energy Regeneration means the generator usually only generates electricity when the driver either takes the foot off the accelerator or brakes – previously unused kinetic energy is transformed in coasting mode into electrical energy before being fed into the battery. In this way, electricity is generated while coasting, without consuming fuel. (all models)
