BMW threw everything it had at the 5 Series to turn it into the M5. Under the hood is a 4.4-litre twin-turbocharged V8 connected to an eight-speed automatic transmission and a plug-in hybrid system. The latter consists of an electric motor integrated with the transmission and a 14.8-kilowatt-hour battery pack. Total system output is 717 horsepower and 738 pound-feet of torque.
That power is channeled to the wheels through an M-specific version of BMW’s xDrive all-wheel drive (AWD), which allows drivers to decouple the front axle to make the M5 rear-wheel drive (RWD). Doing so also deactivates the stability control to make drifting easier (on a track, of course). The Active M Differential also adjusts the power split between the left and right rear wheels, providing a torque-vectoring effect to aid cornering.
In maximum-grip AWD mode, BMW says the M5 sedan will do 0–100 km/h in 3.5 seconds. The M5 Touring takes 0.1 second longer, which is also 0.2 second behind the Audi RS 6 Avant that's due to cease production at the end of the 2026 model year. Still, a hard launch is a proper thrown-into-your-seatback experience. And the M5 will keep accelerating until it runs into its electronic limiter at 250 km/h, or 305 km/h with the $2,500 M Driver’s Package. That package also includes a performance driving class to help owners get the most out of their cars.
Other notable performance features include active steering, adaptive dampers, and powerful brakes. Six-piston calipers and 16.1-inch rotors at the front and 15.7-inch rear rotors with single-piston floating calipers are standard. Carbon ceramics are available for a steep $10,900.
The electronic controls for the chassis and powertrain are well integrated and adjustable. Drivers can individually adjust the steering, brake feel, dampers, and powertrain, as well as the exhaust sound and regenerative braking. Settings can be saved and activated using the steering-wheel M buttons. Road, Sport, Track, Dynamic, and Dynamic Plus drive modes are equipped as standard in Canada.
All this makes the M5 as complicated as it is heavy at a base curb weight for the sedan of 2,445 kilograms (5,390 pounds), but BMW’s engineers made it work. The chassis tech feels natural, the amount of power on tap counteracts the weight, and the grippy tires and AWD system inspire confidence. It’s definitely not the purest driving experience but rather one defined by breadth of capability. The steering is wonderfully precise but lacks feel, and with peak torque arriving at just 1,800 rpm, drivers are approaching illegal speeds before they can really enjoy that V8.
The M5 will make a meal of a favourite driving road while preserving the driver’s back on the more sedate ride home. Even when the dampers are in the Sport Plus setting, ride quality is tolerable on less-than-perfect pavement. Dial everything back to Comfort mode and the M5 is a serene highway cruiser that maintains its quick reflexes. That BMW lets drivers choose degrees of sportiness or comfort rather than making it an all-or-nothing thing is what makes the M5 stand out, even among other luxury performance sedans and SUVs.
