The next-generation M5 carries a quite potent powerplant under its hood.
The next BMW M5 has been seen testing in public again. This time, the next-generation model was caught by CarSpyMedia doing flat-out laps at the Nurburgring. The electrified version, characterized by the mandatory yellow sticker on the rear windshield, was the one in on the action, with test drivers wearing helmets for the high-octane run.
Like the previous sightings, the G90 M5 still wears camouflage during the runs. However, the set of quad-exhaust pipes at the rear can't be concealed. Beyond those, BMW has done a great job hiding the revamped design at the back.
Up front, it's noticeable that the next-generation model is wearing a bigger kidney grille but not as huge as the controversial ones fitted on the M3 and M4. Meanwhile, you can also hear the twin-turbo V8 mill roaring during the session, which will be supplemented by an electric motor for the plug-in hybrid system.
Speaking of the powertrain, it is all but confirmed that the M5 G90 will be powered by the 4.4-liter twin-turbo V8 and plug-in hybrid setup used in the BMW XM. An insider told CarBuzz that this setup will be used in other vehicles coming to market soon, hinting at its usage in the M5 and possibly additional hybrid M cars.
The amount of power produced by the PHEV system is still a mystery. The V8 engine and electric motor in the base BMW XM currently produce 644 horsepower and 590 lb-ft of torque. These numbers might not be enough to carry the added weight from the batteries, making us assume that the upcoming M5 generation could churn out over 644 hp. A hotter Competition or CS model could also happen, which should have the same as (if not greater than) the 738-hp output in the XM Label Red.
The next-generation BMW M5 will most likely debut after the launch of the new 5 Series on May 24. An M5 Touring model is also underway.
