In Spring 2011, BMW launched for the European market the BMW X5 xDrive40d and X6 xDrive40d. The BMW X6 family now includes the xDrive40d model powered by the same 3.0-liter engine found in the 740d. The newly developed 3.0-litre diesel engines now featuring an all-aluminum crankcase raise engine output by 7 kW to 180 kW/245 hp in the BMW X6 xDrive30d and, respectively, 15 kW to 225 kW/306 hp in the BMW X6 xDrive40d – together with a reduction in average fuel consumption in each case by approximately 10 per cent versus the former models.

The power unit comes with common-rail direct injection with piezo-injectors operating in the new top-end diesel version of BMW’s Sports Activity Coupe at maximum pressure of 2,000 bar and in the second diesel at a pressure of up to 1,800 bar.

The power unit featured in the BMW X6 xDrive40d comes with BMW TwinPower Turbo Technology following the Variable Twin Turbo principle where the small turbocharger cuts in just above idle speed and the larger turbocharger is activated under higher load. T

his superior power unit delivers its maximum torque of 600 Newton-meters/442 lb-ft between 1,500 and 2,500 rpm and reaches its peak output at 4,400 rpm. Extra power of this kind accelerates the BMW X6 xDrive40d to 100 km/h in 6.5 seconds and the higher level of efficiency is reflected by average fuel consumption of just 7.5 liters/100 kilometers in the EU test cycle.

The engine is matted to the more powerful and fuel efficient 8-speed ZF automatic transmission. The idea behind this new naming convention is to showcase a smaller, powerful, fuel efficient and low CO2 emission engine that would give the large 4-5 liter diesel engines from Mercedes and Audi, a run for their money.

One of the reasons why the new models diesel models are not yet available in the U.S. market, revolves around the U.S. emission standards compliance in all 50 states.

The folks over at decided to take an X6 xDrive40d with Performance Parts and shoot some rolling footage. Let’s have a look!
