@nay, I agree the new Sequoia is a home run, assuming a long-wheelbase version is coming in a year or two. I think all the engineering tradeoffs point to that likely happening.
They sacrificed storage capacity for the hybrid battery under the third row of seats, and not having to engineer and manufacture an independent rear suspension saved a bundle that helped make the standard hybrid possible.
Mike Sweers, the chief engineer for Toyota's body on frame trucks in North America, has given several interviews where he discusses the engineering and market tradeoffs in deciding what content is in the trucks. Like it or not, it's all about making money, and Toyota tends to make very smart business decisions.
A unique rear suspension for the Sequoia doesn't make economic sense any longer given the global platform. A solid axle and rear locker for off-road functionality is just a happy side effect for the few who will use the Sequoia off-road.
I think Toyota knew they would get panned for the new Sequoia's rear storage, and they are probably readying the solution: charging another five grand for the long-wheelbase Sequoia. Thinking of the profits from engineering and manufacturing an XL version vs. the pure expense for an independent rear suspension to allow more rear space seems like a great business decision.
I looked at the Tundra specs, and the 6.5-foot bed truck is precisely one foot longer in both wheelbase and overall length. The shelf system in the new Sequoia currently seems like it's making up for a deficit, but when they add another foot of space underneath becomes a super desirable feature in my view.
