The reason that the selinoid valvetrain and computer controled valve map,make sense is , no where that I have seen does he state that the car will accelerate, produce 400 hp etc , while delivering 110 mpg. He just says it is capable of all of the above. As far as his grandfather's 60 yr old idea, the concept of variable valve timing to take advantage of both horsepower and mileage has been conceptual for a very long time, although in Grandpa's day the mechanism would have been a mechanical one most likely.
