Mild-hybrid powered BMW X5 and X6 xDrive40d unveiled

BMW has launched a new mild-hybrid diesel powertrain for its two mid-size SUVs, which promises economy figures upwards of 45mpg

BMW X5 xDrive40d

BMW has launched a new mild-hybrid diesel powertrain for its pair of mid-sized SUVs, the X5 and X6. The new set-up promises improved performance, economy and emissions over the brand’s conventional 3.0-litre straight-six diesel unit. Both SUVs are available to order now, with production set to start from May this year.

The German brand’s new mild-hybrid system comprises a turbocharged 3.0-litre straight-six diesel engine, a compact battery pack and a 48-volt starter-generator. The combustion engine produces 335bhp and 700Nm of torque on its own, while the electric motor provides an extra 11bhp on demand.

BMW says the starter-generator helps compensate for the gaps in the combustion engine’s power band, such as when pulling away from a standstill or when the turbo is spooling up from low revs. In both cars, power is sent to all four wheels via an eight-speed automatic gearbox – and both have a claimed 0–62mph time of 5.5 seconds.

The new xDrive40d mild-hybrid system should be more efficient than BMW’s conventional xDrive30d diesel unit, too. The company says the mild-hybrid X5’s economy stands at between 44.1 and 47.8mpg, while the X6 has claimed economy figures of between 45.5 and 48.7mpg. Both SUVs emit less than 160g/km of CO2.

Prices for the BMW X5 xDrive40d start from £59,340 for the entry-level xLine specification and climb to £62,840 for the range-topping M Sport model. The X6 xDrive40d is priced from £61,040 for the cheaper Sport trim-level, rising to £65,540 for the flagship M Sport variant.
