The 2023 BMW XM Is Here and M’s First Bespoke SUV Is a 644-HP Thumper
The XM is the latest test for BMW fanatics: Yet another performance SUV, it also is M's first plug-in hybrid.UPDATE 10/24/22:On Instagram, BMW M revealedan image of the upcoming 2023 BMW XM Label Red, showing off its red (what else?) exterior trim, a striking contrast to the optional "NightGold Metallic" exterior trim seen in the earlier XM images. The red-accented dark wheels also represent a stark break from the black and NightGold wheels below.

The Label Red will go on sale in Fall of 2023. The earlier First Look story continues below.
We were introduced to the Concept XM just short of this time last year, and now BMW M's first plug-in hybrid, the 2023 BMW XM, is entering reality as a five-seat performance SUV with an electrified 4.4-liter twin-turbo V-8 and the ability to be plugged in for some EV-only driving range. That combination—SUV, plug-in hybrid, and, we should add, somewhat odd looks—might be controversial for the BMW faithful, especially when bundled on an M-badged vehicle. Yet the XM has plenty to overwhelm regular folks with, too, including a wild interior design, gold exterior trim, and its nearly $160,000 price tag.
The idea of a high-performance hybrid is no longer "wild" on its own, as the tech has headlined Formula 1 racing for years now and has gradually slid into the mainstream in cars and SUVs alike. Porsche's Cayenne Turbo S E-Hybrid, for example, has taken over the top spot in that sporty SUV's lineup, and Mercedes-AMG is transforming its previously V-8-only C63 sedan into an electrified, four-cylinder plug-in monster. So, BMW's M performance division is mildly tardy to the German power-hybrid zeitgeist.
Plugging Into More Power
BMW hasn't broken the mold with its first plug-in hybrid M car, either. This hybrid system works similarly to the mild-hybrid setup in the three-row 2023 BMW X7 M60. It combines BMW's 4.4-liter twin turbo V-8 pumping out 483 hp and 479 lb-ft of torque with an electric motor integrated into the eight-speed M Steptronic transmission. This 194-hp, 207-lb-ft electric motor gets its power from a 317-volt battery pack with a 25.7-kWh capacity; it can be charged using a 7.4-kW AC charger from empty to full in 3.25 hours (or it can be re-juiced on the go via regenerative braking), and enables the XM to travel up to 30 miles on electric power alone. Combined, the e-motor and the V-8 spit out 644 hp and 590 lb-ft of torque.
Whether running on electricity or a blend of gas and electric power, the XM turns all four wheels with an M-tuned xDrive all-wheel-drive system. The traction xDrive affords helps the hybrid powertrain (along with launch control) punt the XM to 60 mph in a claimed 4.1 seconds. Top speed is limited to 155 mph but can be increased to 168 mph with the optional M Driver's Package added; of course, with only the e-motor running, the XM's top speed lowers to a more pedestrian 87 mph.
To help the XM change direction with M-like authority, it has a 50-50 front-to-rear weight distribution. Also, there is an M Sport rear differential that allows for fully variable distribution of drive power between the left and right wheels. Otherwise known as torque vectoring, the diff can send power to the outside rear wheel to reduce understeer through corners, and it also works in conjunction with the M xDrive and stability control to help keep the XM pointed where the driver wants it to go. Some additional turning assistance comes in the form of BMW's Integral Active Steering, which turns the rear wheels against the fronts for tight, low-speed maneuvers, increases agility at more moderate speeds, and gives you confidence at high speeds and lane changing (when the rear wheels move in phase with the fronts).
The use of sheet steel in the rear suspension links, along with an aluminum subframe and wheel carriers and forged upper control arms, helps reduce weight. But most interesting is that the XM does not use air springs, as does the X7. This not only further reduces mass, but also gives the suspension more consistent feel. The front springs are linear (with a single rate through the spring's full travel) while the rear suspension uses progressive springs, which offers better ride comfort and improved traction with its standard electronically adaptive dampers.
More surprising than the conventional springs? The XM's use of massive 23-inch wheels with 275/35R23 front and 315/30R23 rear tires. Those rims and that suspension must contend with the XM's 6,062-pound (three-ton!) curb weight—surely no easy feat when it comes to keeping the ride comfortable.
