When it comes to hybrid vehicles, the first thing we think of are the economical and fuel-efficient Toyota THS and Honda i-MMD. In fact, hybrid systems are also very popular in products that emphasize high performance such as formula racing cars and super sports cars. A kind of power design idea. The assistance of high-power motors just makes up for the shortcomings of the piston engine's speed-up lag, which can further improve the performance limit of the vehicle.
The "Three Great Cars" in the supercar world
Looking at the global supercar market, products that can break 100km/h in less than 3 seconds are basically blessed with hybrid technology. For example, we are familiar with it. The McLaren P1, Porsche 918 and Ferrari Lafa are the "three great cars".
Mainly rear-engined and rear-wheel drive
Recently, foreign media exposed the power information of McLaren’s new hybrid supercar, the Speedtail. The new car will be equipped with a new hybrid system. Its comprehensive maximum power will reach 1055 horsepower (775 kilowatts), and it will become the brand's flagship powertrain in the future.

Retro long-tail GT sports car
It is reported that this new powertrain will be powered by a 4.0T V8 twin-turbocharger. It is composed of a compression engine, a drive motor and a lithium battery. The engine code is M840TQ, which is an improved version of McLaren's current V8 engine and will be better "compatible" with various electrification transformations of the hybrid system. The maximum power of the body itself is 747 horsepower (549 kilowatts) and the peak torque is 802 Nm. In order to fully emphasize performance control, the high probability of matching the engine is still a dual-clutch gearbox.
McLaren M840TQ 3.8T V8 twin-turbocharged
The M838TQ engine has appeared in the previous hybrid sports car-P1 (3.8T V8 twin-turbocharged engine) , but the new machine head (M840TQ) may have adjusted the piston stroke, so the displacement increased to 4.0L. In addition, referring to previous information, compared to the regular version of M838T, although the design ideas of the "special edition" of the M838TQ are not much different, more than 75% of the parts are specially manufactured and cannot be compared with the 570, 720S, etc. The models are common, and the upcoming M840TQ will most likely be the same.
McLaren P1’s IPAS hybrid system
As a hybrid sports car, the new car will also have a high-power drive motor with a maximum power of 308 horsepower (226 kilowatts) and be equipped with a total Battery pack with a capacity of 1.647kWh. It is reported that its battery pack adopts advanced technology from the Formula E project, and its energy density is four times that of the battery pack used in P1, which is undoubtedly beneficial to reducing the weight of the vehicle.
In order to solve the problem of battery overheating caused by high-intensity charging and discharging, McLaren Speedtail will also be equipped with an insulating cooling system, which uses circulating cooling oil to dissipate heat from the battery pack, and its working efficiency is leading Compared with traditional water cooling and air cooling, it ensures that the battery pack can maintain high-load charging and discharging work for a long time.
Lamborghini’s first attempt at V12+hybrid combination
Electrification transformation has now become an important development direction for high-end products of major sports car brands. Even self-priming diehards like Lamborghini are The newly launched Sián is the first to "try" advanced technologies related to hybrid power. McLaren, Porsche, Ferrari, etc. have spared no effort to carry out more thorough electrification transformation of their products to further enhance the performance of their products. After all, for consumers Generally speaking, the acceleration time of 0-100km/h and 0-200km/h is the most important business card of a car, not one of them.
