BMW realizes it’s a tedious job reading about how technical stuff work. So to explain their new tri-turbo diesel system, they came up with this handy animation.
To be honest with you, it’s still a bit boring to watch, but hey. Here’s what it’s all about in brief: You have two small turbochargers and one big one. This combination means you always have enough pulling power at any rpm. And because this system is implemented on a diesel engine, it also produces a very fat torque figure, which means the car accelerates like it’s nobody’s business. Turbo lag? That’s a thing of the past.
More facts and figures:
The new and globally unique M Performance TwinPower Turbo technology gives the six-cylinder in-line diesel engine powering the BMW M550d xDrive and BMW M550d xDrive Touring maximum output of 280 kW/381 hp and peak torque of 740 Newton metres (546 lb-ft). The engine’s instantaneous and sustained wave of torque allows it to lay down benchmark performance values for diesel-powered executive cars. The BMW M550d xDrive Sedan goes from 0 to 100 km/h (62 mph) in 4.7 seconds, while the BMW M550d xDrive Touring records 4.9 seconds for the same sprint. The duo also display addictive elasticity at higher speeds thanks to their engine’s vast reserves of power. Top speed is electronically limited to 250 km/h (155 mph) in both cases.
The diesel technology developed exclusively for the BMW M Performance Automobiles also gives the new arrivals a convincing head start in terms of efficiency. The Sedan offers fuel economy figures of 6.3 litres per 100 kilometres (44.8 mpg imp) in the EU test cycle, while the Touring achieves 6.4 l/100 km (44.1 mpg imp). CO2 emissions are 165 grams per kilometre for the BMW M550d xDrive Sedan and 169 g/km in the case of the BMW M550d xDrive Touring. Standard-fitted BMW BluePerformance technology also allows the two models to meet the stipulations of the EU6 exhaust standard.
