The New BMW M5: A Heavyweight Contender in the World of Super Sedans

Leaked specifications reveal a powerful plug-in hybrid setup, but concerns arise over its weight

When it comes to new car releases, it seems that each generation is bigger and heavier than its predecessor. The recently leaked specifications of the upcoming BMW M5, codenamed G90, confirm this trend. However, the addition of a plug-in hybrid V8 setup raises questions about the car’s weight and performance. With a reported 718 horsepower and a hefty curb weight of 2,435 kilograms (5,368 pounds), the new BMW M5 aims to strike a balance between power and environmental responsibility.

The Powertrain: A Hybrid V8 with Electrified Boost

According to a reputable BMW insider, the new M5 will inherit the plug-in hybrid V8 setup from the controversial XM. Engineers from Bavaria are allegedly fine-tuning the electrified powertrain to deliver an impressive 718 horsepower. The twin-turbo 4.4-liter gasoline engine is expected to contribute 577 horsepower and 750 Nm (553 lb-ft) of torque, while the electric motor will provide an additional 194 horsepower and 280 Nm (207 lb-ft) of torque. This combination promises exhilarating performance on the road.

Weight Concerns and Emissions Regulations

The reported weight of the new BMW M5 has raised eyebrows among enthusiasts. At 2,435 kilograms (5,368 pounds), it is a staggering 453 kg (998 lbs) heavier than its predecessor, the F90. The decision to incorporate a plug-in hybrid setup instead of using the V8 alone is likely due to stricter emissions regulations, particularly in the European Union. By including hybrid technology, BMW can meet these regulations while still offering a powerful and thrilling driving experience.

The Benefits and Drawbacks of Plug-In Hybrid Technology

While the plug-in hybrid setup in the new BMW M5 offers impressive power, it comes with some trade-offs. The effectiveness of the hybrid system relies on regular charging of the battery. Without regular charging, the additional weight of the hybrid components can increase fuel consumption compared to a pure internal combustion engine (ICE) setup. However, for owners who utilize the battery charging capabilities, the hybrid system can provide improved fuel efficiency and reduced emissions.

Battery Specifications and Weight Comparison

The next-generation M5 is rumored to feature a lithium-ion battery pack with a usable energy content of 18.6 kWh, which is less than the 25.7 kWh found in the XM. Despite concerns about weight, the new M5 is still 606 lbs (275 kg) lighter than the XM. However, it is 287 lbs (130 kg) heavier than the i5 M60, a dual-motor electric vehicle (EV). It is important to note that these weight comparisons are for the sedan version, and the upcoming M5 Touring wagon is expected to be slightly heavier.

Size and Design Enhancements

The seventh-generation M5 is set to be a larger car compared to its predecessor. It is reported to be 1.4 inches (36 mm) longer and 2.7 inches (70 mm) wider than the regular 5 Series Sedan. With an estimated length of 200.6 inches (5096 mm) and width of 77.5 inches (1970 mm), the M5 will have a commanding presence on the road. Additionally, BMW plans to extend the wheelbase for improved suspension geometry, resulting in a distance between the axles exceeding 117.9 inches (2995 mm).

Technological Advancements and Production Timeline

The new BMW M5 is expected to come equipped with 20-inch wheels at the front axle and 21-inch wheels at the rear, paired with high-performance tires. An update scheduled for early 2027 will introduce the Panoramic Vision, a wide head-up display that spans the width of the dashboard. This feature will debut in the first Neue Klasse-based EV next year. Production of the M5 Sedan is set to begin in July 2021, followed by the wagon in November. The sedan version will continue production until February 2031.

Conclusion:

The upcoming BMW M5 showcases the automaker’s commitment to combining power and sustainability. While concerns about its weight persist, the plug-in hybrid V8 setup allows BMW to meet emissions regulations while delivering exhilarating performance. As the automotive industry continues to evolve, the new M5 demonstrates the brand’s dedication to pushing boundaries and finding innovative ways to marry power, efficiency, and cutting-edge technology.
