The BMW X5 and X6 are set to receive an xDrive40d variant complete with the brand's first mild-hybrid diesel powertrain, but BMW Australia isn't planning on bringing them Down Under.
Due in May 2020, the new models will feature a revised 3.0-litre straight six-cylinder diesel mated to a 48V generator and mild-hybrid system.
Output from the diesel unit has been boosted to 250kW with tweaks to the variable-geometry turbocharger and common rail direct injection. The mild-hybrid system will raise power by another 8kW and increase maximum torque to 700Nm between 1750 and 2250rpm.
By comparison, the 2020 X6 xDrive30d we receive in Australia is listed at 195kW, with 620Nm available between 2000 and 2500rpm.
BMW claims the mild-hybrid system will improve engine response and consumption by allowing the combustion engine to maintain a speed “within an efficiency-optimised load range.”
This optimisation results in a claimed 0-100km/h sprint in 5.5-seconds – an entire second less than the 2020 X6 xDrive30d’s 6.5-second claim.
Power will be sent through an eight-speed automatic transmission and xDrive all-wheel drive system.
When asked if we’d be seeing the models here anytime soon, a BMW Australia spokesperson told CarAdvice there are “no plans to introduce those models here at this stage.”
