BMW is keeping the buzz alive for the upcoming 8 Series a year since the concept was first shown. Now, BMW has revealed the specs for the big coupe, at least for the range topping model.

No, it's not the specs of the M8 just yet. It's for the highest-spec standard 8 Series which BMW calls the M850i xDrive. Sadly, it doesn't mark the return of the V12 for the 8 Series but it does have a lot more power than the 850i of the 90's. For the revived 8 Series, the M850i packs a V8 engine, redeveloped for this particular model and comes with a pair of turbochargers.

Range-topping BMW 8 Series packs a 500 PS punch, all-wheel drive

With BMW saying it is a redeveloped engine, chances are the M850i engine is based on the 4.4-liter, V8 from the 7 Series and M550i. In the M550, this particular engine makes 462 PS and 650 Nm of torque. For the M850i, power is up by 68 PS and torque by a whopping 100 Nm. The result is 530 PS and 750 Nm of torque. To reel all that power in, all-wheel drive is standard and it shifts via an eight-speed automatic transmission.

For comparison basis, the 850i from the 90's made 300 PS and 450 Nm of torque. This new twin-turbocharged V8 packs even more power than the potent 850 CSi which made 381 PS and 550 Nm of torque.

For now, the specs for the M850i xDrive will have to do. However, there might be a turbocharged, six-cylinder version to serve as the entry-level model. If one were to follow BMW's current nomenclature, it is possible that it might be called the 840i.
