no idea. Makes no sense to be for them to keep the old 3.3 litre. Shouldn't be that hard to convert since the GS450h uses the 3.5 litre engine. Don't know if it'll be the RX450h. They might keep it as 400h and increase efficiency with that 3.5 litre engine since they can lower the hp of that engine and make the output similar to the old 3.3 litre setup while increasing efficiency. So far, the Prius has the most powerful electric motor at 295lb-ft of torque (even the new Camry's one is only 199lb-ft). They might just drop in a more powerful electric motor. That way, they can keep the power image yet increase the efficiency to satisfy some of the complaints of negligible mileage increase over the RX330.

how much torque does the GS450h Synergy drive produce, since Toyota is claiming it to be the strongest twin motor system that they have built?

The 2GR-FSE, as used in RWD models, is different from the 2GR-FE, as used in the RX350 and other FWD models. The 3MZ and 2GR-FE (FWD) share similar dimensions, but the 2GR heads are a bit bigger because of the dual VVT-i. It shouldn't be hard for Toyota to adapt HSD to the FWD version of the 3.5L and also offer a Hybrid V6 Camry or even an Avalon.

net torque? no idea. Toyota doesn't publish it saying it varies with battery level and stuff (kinda weird since hp also depends on battery state of charge etc yet they publish net hp

).

Only way is to have someone dyno it.

The second motor, the 197-hp MG2 (in real-world operation, the engine and the electric motors together peak at 339 horsepower and 362 pound-feet of torque)

taken from Car and Driver... net torque
