BMW TwinPower Turbo V8 engine in the BMW 550i.
Ability: with the eight-cylinder petrol engine in the BMW 550i you can exploit 300 kW (407 hp) or simply enjoy an impressive 600 Nm as of 1,750 rpm. So what is the secret of the effortless short bursts?
It is the turbochargers in the V between the cylinders. The special, compact design shortens exhaust paths to provide direct responsiveness. The 5.0 seconds in which the BMW 550i accelerates from 0 to 100 km/h are as impressive as the engine's ability to turn any touch of the accelerator into immediate acceleration at any time. When it comes to utilising energy efficiently, the BMW 5 Series Sedan holds the key: precision. With each combustion process, the piezo injectors pump fuel into the combustion chambers at 200 bar with 400 Nm of pure power being delivered to the crankshaft. It's incredible how so little fuel can manifest itself into so much power. Now you can accelerate at any time and never have to worry about high levels of fuel consumption.

How can you improve an engine that has already won six times at the Engine of the Year Awards? With a Twin Scroll turbocharger, Valvetronic and direct petrol injection for a start.
The improvements are evolutionary as each one of the three technologies has been developed further. What is revolutionary however is how they compliment one another. In the BMW TwinPower Turbo in the BMW 535i they are combined in one complete package. The result: 225 kW (306 hp), 400 Nm across a wide speed range and silky smoothness. And all this at a fuel consumption level of just 8.5 l/100 km.
Impressive smoothness and high performance are also what characterise the straight six-cylinder engine in the BMW 523i and 528i. Alusil cylinders and a magnesium crankcase make it one of the lightest six-cylinder engines in its class: 150 kW (204 hp) in the BMW 523i, 190 kW (258 hp) in the BMW 528i. An advantage that you not only notice with the driving dynamics but also with the fuel consumption levels of 7.6 or 7.8 l/100 km. So can these values be improved upon? Of course, with the eight-speed automatic transmission Steptronic.

Luxury without waste. Economic performance. With up to 220 kW (300 hp) and consumption from 6.2 l/100 km the BMW straight six-cylinder diesel engines set the new standards in excellence for tomorrow, today.
For sprints and long-distance: the BMW TwinPower Turbo of the BMW 535d with 220 kW (300 hp) and 600 Nm. The dynamic, free-revving and powerful straight six-cylinder races to 100 km/h in 5.7 seconds. On the other hand, it uses just 6.1 litres of diesel to cover 100 km.
And in the other models, too, the engines unfold their power dominantly and harmoniously: 180 kW (245 hp) and 540 Nm in the BMW 530d and 150 kW (204 hp) and 450 Nm in the BMW 525d. Three litres capacity and a turbocharger system with variable intake geometry already provide maximum torque as of 1,750 rpm. Third-generation common rail direct injection uses a pressure of 1,800 bar to disperse the fuel into extremely small drops making combustion smoother and more efficient. So what comes out of this? On the one side a lot: the BMW 530d accelerates from 0 to 100 km/h in 6.3 seconds while the BMW 525d needs just 0.9 seconds more. On the other side less thanks to the standard particle filter. Thanks to BMW BluePerformance, if requested, the BMW 530d can already meet EU6 emission standards which do not come into force until 2014.

Below 140 g/km CO₂ – for most sedans this is a target for the future. The four-cylinder diesel engine in the BMW 520d undercuts this limit with the same amount of ease as it propels the BMW 5 Series Sedan.
380 Nm and 135 kW (184 hp) are power and performance levels most engines never achieve. The engine in the BMW 520d not only achieves these, it does this on just 4.9 litres over 100 kilometres and with just 129 g/km CO₂ thanks to the same high-quality technologies used in the straight six-cylinder diesel engines. Frictional losses have been reduced by around 3.5 percent compared with its direct predecessor. A pleasant side effect of the increased levels of efficiency: fuel stops only have to take place every 1,400 kilometres. Scheduled to be available as of June 2010. Fuel consumption and emission levels are provisional.
