Re: GM two mode hybrid actual hp and torque?
Two-Mode Hybrid vehicles utilize a specific aerodynamics package, a hybrid electric transmission, a higher efficiency engine and electrically powered accessories to achieve a fuel economy improvement of 30% combined and 50% city over the base models. Combined engine and transmission output is 369 bhp and 380 lb ft of torque, with 332 hp/367 lb ft coming from the 6.0L V8 Gen IV gasoline engine. The Two-mode Hybrid transmission adds the equivalent of the balance of the output, and in addition it increases the time the engine can remain at peak power during acceleration. The fixed gear ratios are designed to let the most power be used over the most useful vehicle speeds

Re: GM two mode hybrid actual hp and torque?
Each of the two motors in the transmission is rated at 80 hp/325 lb-ft peak torque, but unfortunately you can't add engine plus 2 motors peak torque to get 1000+ lb ft of instantaneous torque. In EV only mode, the rearmost motor is driving the wheels, the front motor is providing reaction torque on the engine and also has to be ready to start the engine. Both motors can provide peak torque up to about 2000 rpm, and then their output starts to fall off, like all electric motors. More and more current is required just to keep the rotor spinning the faster you go, so less is available to provide torque to the wheels.
