Today BMW has announced the details of the M550d xDrive, the first example of its new M Performance Automobiles range. Joining the M550d is a Touring version as well as the X5 M50d and X6 M50d.
All are powered by an innovative 3.0 litre straight six diesel engine fitted with three turbochargers, sending power to all four wheels. Peak numbers are 280kW and a stonking 740Nm. It’s the most powerful diesel engine BMW has ever made and they’ve mated it to an 8-speed automatic transmission.
You need to look at the acceleration figures to give those numbers some perspective. The M550d sedan has a dry weight of 1895kg and it can reach 100km/h in a claimed 4.7 seconds. Blimey! The Touring carries and extra 95kg and still reaches 100 in 4.9 seconds. The 2150kg X5 M50d needs 5.4 seconds, while the X6, at the same weight, takes only 5.3 seconds.
It looks as though Australia will only get the X5 M50d and the X6 M50d, which is a shame because the M550d Touring would be our pick by a long margin.
There’s more after the break and if you want to find out more about how those three turbos work make sure you download the detailed press kit, available at the end of the material below.
