This Lexus Magazine interview with Toshio Asahi, chief engineer of the sixth-generation ES, is full of insight into the redesign of Lexus’ top-selling sedan.

(I also talked with Asahi-san about the new ES — look for my interview next week.)

    Electric motor have different torque band , when the engine producing it's peak power , the electric motor might already passed it's peak power range .

     I'm not so sure how the electric motor work on Lexus GS's hybrid system , if the electric motor is work as same rev as the engine , then it would be just like what I said , the different output range made them have 350hp , instead of 400hp . If the engine & motor is work parallel , even 1000 gear also wouldn't made it have combination of 400hp .

    In sport mode, electric motor does get a boost. It gets an additional 150 volts of electricity going from 500 volts to 650 volts.

    Both @LF_EH:disqus & @facebook-607752636:disqus are correct -- there is an immediate power boost with sport mode in the new GS, and calculating overall horsepower is not as simple as adding the engine outputs together. Personally, I find it a bit confusing as well! :-)
