BMW has released a few more details about its upcoming 8 Series Coupé, including the power and torque outputs of the new V8 doing duty in the M850i xDrive variant.

The Munich-based brand says the new 8 Series Coupé (previewed by the BMW Concept 8 Series of May 2017) will go on sale “during the course of 2018”.

And now BMW has revealed that the M850i xDrive, which will slot in below the upcoming full-fat M8, will draw its urge from a “completely redeveloped” V8 engine with a “sporty power delivery”.

So, the headline figures? Well, the 4,4-litre, twin-turbocharged eight-pot will churn out 390 kW and 750 N.m, with the latter available from as low as 1 800 r/min. The automaker says it will reveal other technical figures, such as fuel consumption and CO2 emissions, later in 2018.

The V8 delivers its power to what BMW describes as an “extensively further developed” eight-speed Steptronic sport transmission, characterised by an “expanded spread and further shortened shift times”.

“The new V8 engine offers exactly the right balance between performance and emotion, which is what also sets the new BMW 8 Series Coupé apart,” said Christian Billig, head of drive system integration.

“Above all, the eight-cylinder harmonises perfectly with the further developed Steptronic transmission during dynamic acceleration. At the same time, the sound development of the sports exhaust system authentically reflects the car’s power delivery.

"And thanks to BMW xDrive and active rear axle locking, the engine always transfers power precisely to where it can be best converted into driving dynamics,” he added.
