Toyota Prioritizes 4Runner Heritage, Keeps Roll-Down Rear Window Despite Weight Challenges

Roll-down rear window is a signature 4Runner feature, but adds weight which is challenging when reducing emissions/fuel consumption
Engineers felt roll-down window was "soul of the 4Runner" for uses like dogs sticking heads out and hauling surfboards
Decided early on to keep roll-down window despite weight challenges
Tried to reduce weight in other areas to compensate and meet mass reduction goals
Toyota values 4Runner's 40-year heritage and understands owners use cases like surfing and pets
