The new BMW M5 unveiled! There’s 1 big change, 1 good news and 1 bad news

Not long ago, BMW returned to the 24 Hours of Le Mans with the BMW M Hybrid V8 racing car. This was the first time in 25 years that BMW stood on the starting line of the highest category of Le Mans.

This hybrid racing car is not only a "chariot" that re-creates track legends for BMW, but also a representative of "M" high-performance electrification. It not only uses a 4.0-liter V8 twin-turbocharged engine, but also combines an electric motor and an inverter. Inverter and high-voltage battery pack, with 640 horsepower and 650 Nm, and a top speed of 345km/h.

Today, BMW put a power system with the same origin as the Le Mans racing car into a four-door executive sedan, making it the fastest-accelerating mass-produced model currently in service in the country.

That is the seventh-generation BMW M5 (G90).

Adding a motor is the most direct way to obtain power

That's right, the new generation of BMW M5 has become a plug-in hybrid car. Its hybrid power system consists of a 4.4-liter V8 twin-turbocharged engine and a high-performance electric motor.

Among them, the high-performance motor is integrated into the 8-speed M Steptronic transmission. The M TwinPower Turbo technology used in the V8 engine significantly improves the maximum output power of the new M5 compared with the previous model, reaching It has an astonishing 727 horsepower, and the peak torque has been increased by 250 Nm to 1,000 Nm. The acceleration time from zero to 100 kilometers is 3.5 seconds.

A careful inspection of the configuration table shows that this S68 (S68B44T0) engine has a power of 577 horsepower, a speed limit of 7200rpm, and a peak torque of 750 Nm between 1800-5400rpm.

Sure enough, if you want to go faster, just add a motor.

The increase in output power brings stronger rear-end acceleration performance. The new M5 accelerates from 0-200km/h faster than the previous model, taking only 10.9 seconds. The top speed is limited to 250km/h with the optional M driving package. The speed limit can then be relaxed to 305km/h.

BMW also said that in fifth gear, the G90 M5 accelerates from 80km/h to 120km/h in just 2.9 seconds. If it is in fourth gear, this figure will drop to 2.2 seconds.

The power system of the new M5 has a total of five driving modes, including pure electric, hybrid (default), and eControl power-saving mode. The two modes of dynamic and dynamic enhancement can only be turned on after the M driving package is optionally installed.

It should be noted that the acceleration capability of the new car in pure electric mode is much slower than normal, with a top speed of only 140km/h, and it usually requires a more "grocery shopping" speed to reach the 60km WLTP pure electric range claimed by BMW. In terms of cruising range, under more stringent EPA test conditions, its pure electric cruising range is only 40km.

This 40 kilometers of pure electric range comes from a lithium-ion battery with a capacity of 18.6kWh. It is placed under the car body to lower the center of gravity of the vehicle. It supports AC slow charging. It takes 3 hours and 15 minutes to fully charge with a power of 7.4kW. It is not supported at the moment. DC fast charging.

The good news is that the new M5's driving mode is very customizable. The throttle, gearbox, chassis, steering and brakes can all be customized. The four-wheel drive system can also achieve customized power distribution between the front and rear axles.

There is also a new Boost Control function. In the speed range of 32km/h to 144km/h, the driver can activate this function through the paddle on the left side of the steering wheel to uniformly set the power, transmission and chassis systems to The sportiest gear to propel this nearly two-and-a-half-ton beast.

Yes, combining a large-displacement engine, electric motor, and battery inevitably creates weight issues. BMW said that the G90 M5 weighs 2445kg in the United States (US battery is 14.8kWh) and 2425kg in Europe.

For the size of the new M5, which is 5 meters long and nearly 2 meters wide, this is still a less than ideal figure. It is almost as big as a Land Cruiser. It is more than half a ton heavier than the previous generation model, and even It's heavier than the all-electric 2024 i5 M60 xDrive.

But BMW claims that in the face of their tuning skills, this weight is not a problem.

No matter how heavy it is, it must be easy to drive.

At the front end of the new BMW M5, there is a piece of reinforcement spanning the shock absorbers and firewall, in the middle of the tower roof and in the middle and rear of the cabin. BMW has used a series of reinforcements to strengthen the structure. The rear of the vehicle is equipped with a unique chassis cross member and additional reinforcements for the trunk.

In addition, the body structure of the new M5 is also stronger. The connection between the chassis and the body and the connection between the steering system and the front axle subframe have excellent torsional rigidity. The variable steering system works together with the Servotronic power steering system to ensure road feel feedback and precise directionality.

In terms of chassis, the new M5 uses an adaptive M sports suspension equipped with electronically controlled dampers. The solenoid control valve will adjust the suspension damping in real time. During dynamic driving, the integrated active steering system can make the rear wheels rotate synchronously or reversely with the front wheels according to the vehicle speed. The maximum steering angle of the rear wheels is 1.5°, which can improve handling stability at high speeds and reduce turning to a certain extent. radius.

The M xDrive all-wheel drive system adopted by the new M5 this time has been specially tuned for the engine and motor, which can quickly and accurately distribute huge power to the four wheels. The rear axle differential can also significantly improve the vehicle's handling.

Due to the substantial increase in vehicle weight, the new M5's braking system has also been upgraded. The front axle is equipped with 6-piston fixed calipers and a 410mm brake disc, and the rear axle is a set of single-piston floating calipers.

You can also choose a set of 420mm carbon ceramic brake discs for an additional fee to improve the durability of the braking system in intense working conditions. Its weight is also 25kg lighter than the standard steel brake pads, and the calipers have also been replaced with logos. The golden color of sex.

The wheels used on the new M5 have also changed. The front wheels remain at 20 inches, but the rear wheels are increased to 21 inches, equipped with 285/40 R20 and 295/35 R21 tires respectively.

The new M5 looks very “M”

As expected, the new M5 looks more aggressive than the regular 5 Series, with the front wheels wider by 7.62cm and the rear wheels 4.83cm wider. With its unique M grille, split rear diffuser and quad exhaust, it doesn't look like an ordinary 5 Series.

While some wish BMW could return to a time of simpler, cleaner lines, for now you just have to live with it.

On the interior, the new M5 looks similar to the regular 5 Series, but the amount of carbon fiber is significantly increased. The steering wheel is a new three-spoke M leather steering wheel with a flat bottom and a red mark at 12 o'clock. The programmable M buttons on both sides of the thumb and the rear shift paddles have been redesigned, and the small shift lever at hand has also replaced the "bulky" shift lever on the F90.

Above is the standard panoramic sunroof with sunshades. Of course, you can also choose a carbon fiber roof, which reduces the weight by 30.45kg and also has a higher keyboard value.

As for the sense of luxury, the seats wrapped in merino leather and the 18-speaker Bowers & Wilkinson audio will give you that.

M5 is the beginning of an era

In 1985, BMW M boldly implanted the mid-mounted engine on the BMW M1, the 3.5-liter inline six-cylinder engine, into the 5 Series, creating the first-generation M5 (E28).

This is an epoch-making product that breaks the boundaries between luxury and sports with performance and elegance, perfectly combines high performance with medium and large business sedans, and creates the "high-performance sedan" market segment.

With the change of technology, the third-generation M5 (E39) uses the same power system as the BMW Z8, becoming the first M5 model to use a V8 engine. The fourth-generation M5 (E60) is the first to adopt BMW's traditional F1 engine. The high-revving V10 engine has become the M5 with the largest number of cylinders in history.

It can be found that almost every generation of M5 represents BMW's most cutting-edge technology of that era, and now, using electric motors to assist internal combustion engines is the best choice for performance cars.

BMW said that BMW M will expand its product lineup around "electrification" in the future. It is expected that by 2027, half of BMW M's models will be new energy vehicles.

The M5 launched today is just the beginning.
