BMW just unveiled the new 7-Series lineup this morning, including the electric i7 xDrive60 and the petrol-powered 740i and 760i xDrive. However, there are more models coming soon.

In the all-electric realm, a new flagship called the i7 M70 xDrive will finally be unveiled. According to BMW, the M Sport model is said to have “over 600 horsepower and over 737 pound-feet of maximum torque.” When it’s revealed, those numbers will easily make it the most powerful 7 Series in the lineup. BMW also says it will do the 0-62 mph sprint in “under 4.0 seconds.”

When it was revealed, BMW promised the i7 M70 would be the company’s most powerful road car ever. Still, we suspect it won’t last long after the 740-horse XM is released on the street. We’ll also note that BMW marked these i7 M70 power claims with an asterisk, saying the numbers reflect a temporary “uplift” that we’ve seen in many EV models. This means that it will be able to generate quoted power data for a short period of time, but not permanently.

In addition to its upcoming exciting electric flagship, BMW also told us we’ll have a plug-in hybrid model coming in 2023. It will be the 750e xDrive, and while there is no U.S. specification, the model has been announced for Europe. It uses a 3.0-liter turbocharged inline-six engine and an electric motor. The combined power between the two is a strong 490 horsepower and 516 pound-feet of torque – BMW claims a 0-62 mph time of 4.9 seconds. Performance-wise, that makes it a tad quicker than the 740i, which claims a 0-60 mph time of 5.0 seconds.

Electric range is currently only quoted for the WLTP cycle, but that’s a high estimate of 52 to 57 miles. We’ll have to wait and see how this translates to EPA-rated range, but we’re hopeful since it’s a sizable 18.7 kWh battery pack. The lithium-ion battery is mounted on the underside of the car, and BMW claims trunk space isn’t affected by this new packaging.

For now, that’s all we know about these upcoming models. If you’d like to download everything BMW has fully disclosed, go ahead and check out our full disclosure story here.
