On top of that Yamaha developed unique aluminum cylinder heads, as well as titanium intake valves, a water-cooled oil cooler, and a head scavenge oil pump, all devised for better high-speed and high-load driving.
So, ya, exactly like the Tundra engine.
2. No it's not. The Crown runs a 6 speed auto. The IS F has the new 8 speed that it shares with the LS.
3. Again...no it doesn't. The Mark X and Crown share their platforms with the GS. The IS is based off of the GS platform, but is a shortened version.
Okay, the AA80E transmission is actually used on the Crown Majesta
I really dont understand the point you are trying to make with the others. You said your IS-F did not share anything
with Toyota but are now admitting that the engine and chassis were developed from existing products.
