Toyota innovations

I was reading this article earlier this evening trying to think why GM would can such a great idea that Toyota obviously picked up and ran with on the 2nd Gen. Tacoma.

GM has had some humdingers in the past which got me wondering about what awesome ingenuity Toyota may have dropped over the years. Post if you have some obscure knowledge of something that Toyota used to do that was extra innovative.

i.e. Buick GNX, GMC Syclone, special order codes to get a track ready SS Camaro, Pro-Tec box, Quadrasteer, etc.

 

What the hell is "cab rattle"? Don't recall ever seeing that complaint in the past year or so on TW.

 

X2 no rattle here
