Kai lists the flaws that make each new TNGA-F product less appealing for technical offroading:
Tundra: too on-road focused, sacrificed off-road capabilities. Questionable engine reliability.
Tacoma: wheelbase is too long on most trims other than the most basic ones.
GX: front overhang too long due to E-KDSS packaging.
J250 LCP: too much weight reduction by using thinner parts. Questionable durability under heavy stress.
It really makes me wonder how well the new light-duty platform could achieve its intended durability target. The J250 is the same size as J200 but almost 500kg lighter and also 300kg lighter than the J300. Their chief engineer did say they try to save weight wherever possible without sacrificing durability, but we don't know how true it is.
