BMW X5 and X6 M50d


The new line of BMW M Performance Automobiles also includes two super diesel versions of the BMW X5 and X6.

The are powered by the same engine as the M550d saloon. The engine developed for the BMW M Performance Automobiles generates maximum output of 280 kW/381 hp and peak torque of 740 Newton metres (546 lb-ft), making the two BMW X models the envy of every other diesel-engined model in this segment. The BMW X5 M50d races from 0 to 100 km/h (62 mph) in 5.4 seconds, while the BMW X6 M50d brings that time down to 5.3 seconds.

As for the fuel economy, the X5 does 37mpg and the X6 a little less than that. Still, pretty impressive. These cars look like the perfect SUV’s for this day and age, but they both cost near as makes no difference 85,000 Euro.

BMW xDrive: intelligent control, optimised to enhance dynamics.

The BMW xDrive all-wheel-drive system uses an electronically controlled multi-plate clutch to distribute the engine’s power between the front and rear wheels variably and according to the situation at hand. Indeed, drive can be switched between wheels in a split-second to optimise traction, directional stability and driving dynamics. xDrive and the DSC stability control system work together to provide advance analysis of the driving situation ahead. The ability to detect the danger of drive slip at an early stage and counteract one or several spinning wheels by varying the distribution of power has helped earn xDrive its status as an intelligent all-wheel-drive system.

In normal driving situations drive is sent predominantly to the rear wheels, accentuating the renowned handling characteristics of BMW cars. The M-specific set-up of the BMW X5 M50d and BMW X6 M50d has been optimised to enhance dynamics, helping it to retain a rear-wheel bias under dynamic cornering. Even when the car is stable through corners, a larger proportion of the engine’s power is channelled to the rear axle to enhance agility and stave off understeer.

In addition, Performance Control enhances the handling agility of the BMW X5 M50d, while Dynamic Performance Control does a similar job for the BMW X6 M50d. As soon as the front wheels of the BMW X5 M50d start to push excessively to the outside of a corner, the control electronics of xDrive and DSC team up to brake the rear wheel on the inside of the bend as required. The loss of forward propulsion is balanced out by an increase in engine power, the intervention of Performance Control ensuring precise turn-in. Power distribution can be varied to an even greater degree in the BMW X6 M50d, which comes as standard with Dynamic Performance Control. This system reroutes engine output from the inside rear wheel to the outside rear wheel around a corner if the system detects an imminent risk of understeer. Dynamic Performance Control also counteracts oversteer in its early stages, switching drive from the outside rear wheel – which is experiencing particularly high centrifugal forces – to the inside rear wheel. Dynamic Performance Control also steps in to stabilise the car when the driver takes his foot off the accelerator, ensuring precise and agile turn-in and enabling extremely dynamic acceleration out of corners.

Stronger body mounting reduces roll, which in turn optimises steering accuracy through corners. At the same time, the linear build-up of lateral forces for which M cars are renowned enables precisely controllable handling up to the limit. The M-specification tuning of chassis components extends to the electronically controlled dampers and active anti-roll control function of Adaptive Drive, which comes as standard on the BMW X6 M50d and is available as an option for the BMW X5 M50d. Meanwhile, the large-format braking system – with 385-millimetre front discs and 345-millimetre rear discs – provides powerful and consistent braking, even under heavy loads.
