BMW has announced details of new flagship models for its X5 and X7 SUVs each with upgraded 4.4-litre V8 engines. The engines are based on the company’s TwinPower Turbo technology and generate up to 390 kW of power from 5500 rpm and 750 Nm of torque between 1800 and 4600 revs.
As a result, the new BMW X5 M50i is able to accelerate from zero to 100 km/h in 4.3 seconds and the X7 M50i in 4.7 seconds.
Both models combine the V8 engine with an eight-speed Steptronic sports automatic transmission, BMW’s xDrive all-wheel drive system and a model-specific suspension technology, developed with BMW M high-performance division.
A number of major engine components have been upgraded since the previous version including the crankcase, cylinder barrels, pistons, crankshaft and cylinder head. The twin turbochargers have also been enlarged.
Combined cycle fuel consumption is listed at 10.5 L/100 km from the X5 M50i and 10.9 L/100 km from the X7 M50i with CO2 emissions of 238 g/km and 248 g/km respectively.
Standard wheels are 21-inch M light alloy wheels complete with mixed tyres. These can be optioned up to 22-inch light alloys, again fitted with mixed tyres.
Also standard are electromechanical steering with Servotronic function and an M sport brake system with blue-coated brake calipers complete with M logo.
The new BMW X5 M50i is equipped with Adaptive M suspension and the X7 M50i is fitted with adaptive dual axle air suspension, which will also be available as an option with the new X5 M50i.
Externally the new variants will be distinguished from other models in the range by extra-large air inlets in the front apron, different designs of the side sills and rear apron, the BMW individual high-gloss Shadow Line, and selected design elements in Cerium Grey.
The new BMW X5 M50i and the new BMW X7 M50i will be produced from August 2019 at the BMW plant in Spartanburg in the USA and will be available in Australia later in the year. Local specification and pricing will be provided prior to the launch of the new models.
