According to a BMW blog post, the BMW XM is not only the most pricey BMW ever made but also the most powerful — featuring fifth-generation battery technology.

“The BMW XM isn’t based off of any pre-existing BMW product and was solely designed to be an M car,” the blog post reads.

“Along with being the most expensive BMW ever made, at least until the $750,000 3.0 CSL arrives next month, the BMW XM is already the most powerful car in the brand’s history,” it continued. “Thanks to a 4.4-liter twin-turbocharged V8 hybrid powertrain, it makes 644 horsepower and 590 lb-ft of torque, which is more powerful than the previous BMW-leader, the M5 CS with its 626 horses. However, there’s an even more powerful model coming, packing a whopping 750 horsepower.”
