>directly countered by the existence of the Toyota Prius,
The transmission design in the Prius is a lot more simple than a conventional automatic transmission. The engine is also so overbuilt that I've seen Prius engine swaps (sans hybrid system) into other Toyotas the basis of race engines. The 1.5L had forged crank and titanium conrod (very rare, even in sports cars), which could be pushed to 10,000RPMs with some valve springs.
