Interesting thought on Ford's Eco Boost engines

Is this supposed to be some giant mystery or something? It's really pretty simple. The Eco boost has Hp when you need it, and economy when you don't. If you use your truck as a daily driver (like I do) you can have the economy 80% of the time, and only pay extra the 20% of the time you need the Hp for towing. Coupled with the 10 sp transmission that's a combination hard not to like.
Same basic principal as that diesel with the turbo on it.
