I'm all for the hybrid. And the turbo if done right. My core reason I don't want the hybrid as it is now is because battery is too small to be useful. It's only good for about 45 seconds of power. So, it's great for city driving. But it isn't enough energy to help with towing or hauling up mountain passes. And that's where it really needs the extra power. It needs more battery capacity to offset the extra 600lbs of weight and loss of storage. For my use, the slightly faster 0-60 just isn't worth the tradeoff. 27mpg sounds fantastic though if that's real. I'm skeptical because it's the same hybrid as the Tundra that only adds 1mpg and the GX550 supposedly only gets 17mpg. And according to Toyota the two engines should have roughly the same thermal efficiency - they should get about the same mpg at steady cruising speeds.
If it were a PHEV version with a 10 or 20kwh battery - I'd be really excited about it. Not because I need more than the 325hp, but if I'm giving up the space and weight, I really want useful power - 325hp for the 5 or 8 minute duration up a mountain pass. And I'd like to have regen braking on the way down. I'd also like to have the ability to run EV only for water crossings. No snorkel would ever really be needed in that case. Just plug the intake and switch to EV drive. Lots of cool stuff could be done.
