Hybrid 911, no green license, no vegetarian
The "longest-lived" sports car series on Earth, aside from the Ford Mustang, is the Porsche 911. Why does every driving enthusiast want to make the 911 their ultimate ride? I believe it is the historical accumulation of nearly a century in the automotive industry that has shaped the 911's current status.
When the people of Stuttgart unveiled the 911 hybrid—the 911 Carrera GTS—I knew that Porsche not only understood what drivers want but also refused to follow the new energy trend for "political correctness"—by not offering a plug-in hybrid (PHEV) or conventional hybrid (HEV) 911 to appease car enthusiasts around the world.
After all, the 911 is just too important for the company.
01
Why the 911 Hybrid T-Hybrid Doesn't Have a Green License PlateFor some Chinese consumers, it may be puzzling why the 911 hybrid is not a plug-in hybrid structure like the Panamera or Cayenne E-Hybrid (EA888 + battery + drive motor), but rather a hybrid principle without any drive motor.
Why does it adopt a HEV hybrid structure but cannot drive purely on electricity?
Firstly, the motor is integrated into the exhaust turbocharging, presented in the form of an electric turbocharger eTurbo. With the motor located between the same axis as the turbine, the pulse inverter allows the single turbine to quickly build pressure. The turbine motor, under the high-temperature and high-pressure conditions of 130,000 rpm, additionally outputs a maximum horsepower of 65PS and a peak torque of 150Nm. This achieves zero-delay turbo power output, and the "hybrid turbine" makes the engine speed climb even more aggressively.

Not only that, but the eTurbo can also convert the kinetic energy of the exhaust turbine into electrical energy, similar to the turbo generator in Porsche's 919 Hybrid race car, without the need for a wastegate valve.
Secondly, the PDK gearbox also integrates a P2 permanent magnet synchronous motor at the flywheel - a technology derived from the 911 GT3R Hybrid race car, which was validated in the 24-hour endurance race at the Nürburgring. It recovers energy during braking, charging the lightweight high-voltage 400V liquid-cooled lithium-ion battery pack located at the front of the vehicle.So, even though it can't travel purely on electricity, the additional 56 horsepower and 150 N·m of torque output provide a silky smooth hybrid experience during takeoff and gear shifts, which is the biggest difference in how the 911 hybrid drives compared to previous models.
The 27 kg lithium-ion battery pack at the front of the car weighs about the same as the starter battery in a traditional fuel vehicle. In this design, it shares a similar structural principle with Lamborghini's Sian, which uses capacitor energy storage and discharge technology. However, the supercapacitor technology in the multi-million-dollar Sian is much more expensive. The 911's use of lightweight high-voltage batteries within an appropriate cost range is also a solution.
The horizontally opposed 3.6L turbocharged engine specially developed by Porsche for the hybrid system can output 485 PS and 541 Nm. Although the maximum engine speed is only 7500 rpm, the maximum power output has increased compared to the previous 3.0T's 450 PS. Ultimately, with the assistance of the eTurbo electric motor, the 911 hybrid has a combined output of 541 PS and a combined torque of 610 Nm. The 0-100 km/h acceleration time is 3.0 seconds, which is 0.7 seconds faster than the 991.2 GTS and only 0.3 seconds slower than the current 992 Turbo S.
The battery and dual electric motors add 50 kg to the weight, making the car 100 kg heavier than the 992 standard version and 179 kg heavier than the 991.2 GTS. Porsche has leveraged the advantages of new energy batteries and electric motors - significantly enhancing the performance and power response of the 911, while perfectly preserving the traditional sensory experience of the 911. This is the power of the T-Hybrid system.
The standard GTS version weighs 1649 kg, which is an acceptable range for a 911. After all, the 911 hybrid is still 25 kg lighter than the current all-wheel-drive twin-turbo Turbo S.As for the future all-electric 911, I'm afraid that if you want to drive a 911 weighing over 2 tons on the track, you can turn right and choose the Taycan Turbo GT.

The 911 hybrid is the revised 992.2 GTS
There are no major changes in the overall appearance, just some detail optimizations—after all, the 911 that doesn't change much is the authentic 911. The GTS model's drag coefficient has been reduced from 0.32Cd to 0.27Cd, thanks to the front grille changing from a traditional fixed design to five vertical active air guides, which optimize cooling and aerodynamic performance.The 992.2 GTS is also equipped with an adaptive front diffuser on the underside of the car, which is linked and controlled with the cooling air ducts.
The changes inside the car are naturally not many, adopting the same all-digital instrument panel as the Taycan, with the central mechanical pointer tachometer becoming a thing of the past, but the 12.6-inch curved screen display interface remains the classic 5-gauge layout, with the tachometer in the center. The 992.2 also follows up with a fully digital cockpit in the facelift, with a 10.9-inch central control screen that can use domestic third-party applications such as QQ Music and Bilibili. The most important change is that the Le Mans-style left-hand start knob has been changed to a one-touch ignition button. However, even so, the tradition of starting with the left hand and shifting gears with the right hand cannot be lost.
On the 992.2, the soul of the 911 after full digitalization is still there!

Nurburgring lap time of 7 minutes and 16 seconds, 8.7 seconds faster than the 991.2 GTS.In addition to a power increase of 91Ps, the new 3.6T engine is 110mm lower than the existing 3.0-liter engine, which allows for a lower center of gravity and better handling in a rear-mid-engine, rear-wheel-drive layout. The newly developed 3.6L single-electric turbocharged engine actually increases in displacement in the era of electrification, while the overall size of the engine is reduced.
Eliminate the belt and chain mechanisms. The drive components for air conditioning and water pumps are changed to electronic wheel pumps controlled by a 400V high-voltage platform. The only concern is whether the perfect quality control and stability of the 911 will be compromised by these electronic pumps.
0-200km/h acceleration in 10.5 seconds, with a top speed of 312km/h. The actual data changes are not significant, but I believe that after reaching a speed of 200km/h, the 3.6L engine has a stronger power output than the previous generation's 3.0T. The final 2km long straight uphill section in the Nürburgring is a great test of the vehicle's power output in the latter stages. The speed through the Pflanzgarten bridge will be at least 10km/h faster than the previous model, which can save a lot of time on the straight.
The 992.2 GTS comes standard with 245/35 R20 front and 315/30 R21 rear tires. The rear wheels are one size wider than the 305 width of the 991.2. The rear axle steering system has become standard on the 992.2 GTS, which improves the stability of the rear of the car at high speeds, especially in the Schwedenkreuz left turn where the speed exceeds 200km/h. The difference in confidence for the driver and the noticeable difference in cornering speed between cars with and without rear axle steering is significant.Jia Shi Summary
When the GT3 RS has squeezed the naturally aspirated engine to its limits and the Turbo S power has not seen substantial improvement—going electric is currently the best solution for the 911.
However, Porsche's T-Hybrid hybrid system is not about asceticism for the sake of the environment, but still serves only sportiness and performance.
Of course, in my opinion, it's a good thing that the 911 hybrid has not catered to the Chinese market by becoming a pure electric vehicle.
I believe that every car enthusiast in the world has a 911 as their ultimate dream car, but few would have a pure electric 911 as their totem.Please provide the text you would like me to translate into English.
