BMW 750Li:

Eight-cylinder engine develops more power but burns less fuel.

Making its debut under the bonnet of the BMW 750Li is an upgraded BMW TwinPower Turbo eight-cylinder petrol engine with two turbochargers, Valvetronic, Double-VANOS and High Precision Direct Injection.

The 4,395 cc eight-cylinder powerplant retains the impressively smooth assurance and spirited power delivery of its pre-update days. However, optimised high pressure direct injection and reduced charge cycle losses – thanks in the main to the seamlessly variable control of intake valve lift – have pushed its performance potential to a higher level than its predecessor and substantially reduced its fuel economy and emissions.

In its latest development stage, the engine generates peak output of 450 hp (+ 10 percent) and unleashes peak torque of 650 Newton metres (+ 8.5 percent) between 2,000 and 4,500 rpm. The engine teams up with the eight-speed automatic transmission, allowing the BMW 750Li to sprint from 0 to 100 km/h in just 4.8 seconds and progress on to an electronically governed top speed of 250 km/h.

The eight-cylinder engine belies its improved performance with better efficiency than ever; with overall fuel consumption of 8.6 litres per 100 kilometres and CO2 emissions recorded at 199 g/km, the BMW 750Li trumps its less powerful predecessor by a clear 25 percent.
