Powertrain & Engine Architecture

At the heart of the M5 Touring (G99) lies the S68B44T0 4.4-liter twin-turbocharged V8 engine, paired with a powerful electric motor integrated into the eight-speed M Steptronic automatic transmission. The combustion engine produces 585 horsepower and 553 lb-ft of torque, while the electric motor adds another 197 horsepower and 206 lb-ft of torque, resulting in a combined system output of 727 horsepower and 737 lb-ft of torque. The engine utilizes direct fuel injection and BMW’s VALVETRONIC and Double-VANOS technologies for optimized efficiency and responsiveness. The 18.6 kWh usable battery capacity allows for an all-electric range of 37.9 to 41.63 miles (WLTP). The M Steptronic transmission is specifically tuned for the hybrid powertrain, offering smooth and rapid gear changes. The electric motor is strategically positioned between the engine and transmission, contributing to a balanced weight distribution.

Driving Characteristics

The 727 hp plug-in hybrid powertrain delivers breathtaking acceleration, achieving 0-60 mph in just 3.4 seconds. The instant torque from the electric motor fills in any potential turbo lag, providing a remarkably linear power delivery. While the added weight of the battery pack and electric motor (resulting in a curb weight of 5456.44 lbs) is noticeable, the M5 Touring maintains exceptional handling characteristics thanks to its sophisticated suspension and xDrive all-wheel-drive system. The eight-speed automatic transmission is well-matched to the engine’s powerband, offering both responsive downshifts and comfortable cruising. Compared to the standard M5, the hybrid variant offers a quieter and more refined driving experience in electric mode, while still delivering the exhilarating performance expected of an M car when both power sources are engaged.

Equipment & Trim Levels

The M5 Touring (G99) 4.4 V8 comes standard with a comprehensive suite of luxury and performance features. Interior appointments include Merino leather upholstery, M Sport seats, and carbon fiber trim. Standard technology includes BMW’s iDrive 8.5 infotainment system with a 14.9-inch touchscreen display, a digital instrument cluster, and a premium sound system. Available options include ventilated and massaging seats, a head-up display, and advanced driver-assistance systems such as adaptive cruise control and lane-keeping assist. Exterior features include M-specific aerodynamic enhancements, quad exhaust outlets, and M light alloy wheels.

Chassis & Braking

The M5 Touring features a robust chassis with a coil spring, double wishbone front suspension and an independent multi-link rear suspension, both incorporating transverse stabilizers. The braking system consists of ventilated discs at all four corners, providing ample stopping power. The xDrive all-wheel-drive system intelligently distributes torque between the front and rear axles for optimal traction and stability. Active rear steering is also standard, enhancing agility and maneuverability, particularly at lower speeds.

Market Reception & Comparison

The M5 Touring (G99) has been widely praised by automotive critics for its exceptional performance, luxurious interior, and practicality. The plug-in hybrid powertrain is seen as a significant step forward, offering improved fuel efficiency and reduced emissions without sacrificing driving enjoyment. Compared to the standard M5 sedan, the Touring variant offers increased cargo space and versatility. While the hybrid system adds weight, the overall driving experience remains remarkably engaging. Fuel economy is rated at 2.0 l/100 km (117.6 US mpg), a substantial improvement over the non-hybrid M5.

Legacy

The BMW M5 Touring (G99) 4.4 V8 represents a new chapter in the M5’s storied history. As the first M5 Touring offered in the US market, it is poised to become a highly sought-after vehicle among enthusiasts. The combination of a powerful plug-in hybrid powertrain, luxurious appointments, and practical wagon body style makes it a unique and compelling offering in the high-performance segment. The long-term reliability of the S68 engine and the hybrid system remains to be seen, but BMW’s reputation for engineering excellence suggests that this powertrain will prove to be durable and dependable. The G99 M5 Touring is expected to hold its value well in the used car market, appealing to buyers who appreciate both performance and practicality.
