The Ultimate MPG thread.
Sorry, but the theory and practice agree. You may be working the engine harder, but you do it for a shorter period of time. It takes the same amount of energy to accelerate 5500 lb to 60 mph in 10 seconds as it does to do it in 60 seconds. The main difference is that brisk acceleration can afford you more opportunity to coast if you're paying attention and planning ahead.
The point he was making is that a higher level of energy spent over a short period of time is comparable to a lower amount spent over a longer span of time.
