Toyota’s hybrid system has not been implemented in a Toyota truck. It is new technology being implemented for the first time, using a new engine, in a new car. That is three concentric risk factors overlapping. I will wait at least 2-3 years, skip the intermediate, short term, stop gap hybrid tech to see how this all shakes out because the real prize here is full EV in our trucks with Toyota coming soon. That is an absolutely exciting prospect worth the wait. Keep your powder dry.
Toyota had never made a V8 engine for mass production, and had never made a luxury car before, but the Lexus LS400 is legendary for reliability.
Toyota had never put a V8 into an SUV before the 1998 Land Cruiser 100.
Toyota had never made a full sized truck before, but the T100 is legendary for reliability.
Toyota had never put a V8 into a full sized truck before the Tundra, and we all know about the 'million mile' Tundras ad nauseam.
Toyota is a conservative company, and they aren't going to put iffy tech into their flagship vehicles unless they are extremely confident in the tech.
As an aside, for the way I use my truck, a 500 mile range is what I will need, and thats going to have me sweating bullets (I figured offroading is going to be a 30% reduction in battery, more if I am running heat or air conditioning, and I do trips where it's common 310 miles between fuel stops).
Then there is the issue of the industry not being able to decide on a rapid charge standard. 6 months ago, the automotive rags were saying Supercharger(NACS) is dead and every manufacturer was going to CCS. Well, now everyone is going to NACS. But, I can wait for 'the market to decide'.
I don't think EV's are going to be able to replace the Tacoma I own any time within the next 10 years, and even then, EV rapid charge will need to be as commonly available as gasoline stations for me to even remotely consider adopting one as a replacement to my Tacoma.
I feel that for now and for me, a hybrid truck is the best compromise between ICE and BEV
A BEV commuter vehicle that is used purely for commuting, or for road trips on Interstate Highways is a different story.
