went to detroit for this a mont or so ago but didn't get to drive one. we got one in yesterday and no sooner did it get off the truck and we took it for a test drive.
Sticker $54,290 loaded. 4WD, NAV, leather ect.
after the engine reaches operating temp. then it will go into Auto Stop mode, the transmission has 2 electric motors in it that run off 300v 3-phase electric. under 23mph the truck will opperate in hybrid mode depending on throttle input. if your light on the go pedal then the engine will remain off, read big golf cart. between 23-60 it will work in hybrid assist mode, engine and electric and at 70 its in full gas mode but does have DOD. fuel mileage is 20/20 average. they did add alot of weight to it so they tried to cut as much as they could. the hood and rear hatch is aluminum and there is no electric hatch lift. the seats are only 6 way power not 8 way. the A/C compressor is 300v electric and 42v power steering.
Braking is different than anything you will drive. its called regenerative braking, the hybrid control module determins if it should just apply more to the electric motors to use the truck speed to recharge the batterys in turn slows the truck down because of the drag of making electricity or apply hydraulic brakes. when you push the brake pedal you are not moving any fluid, just an input into a module which turns on the ABS motor that applys the brakes. if the system fails then you have to push farther on the pedal and it will then apply hydraulic brakes manualy to the front wheels only.
i would rock it, in stop and go traffic you could see even better fuel mileage than 20mpg. its a nice truck and rides nice. it also has a different front end thats more aerodynamic to help some. plus you get a huge tax brake for buying one.
