1.0-liter EcoBoost achieves 45 mpg on the highway

Ford has officially announced that the 2014 Fiesta using the new and very small three-cylinder 1.0-liter EcoBoost engine is officially the most fuel-efficient non-hybrid vehicle in America. The little 1.0-liter engine is able to achieve 32 mpg in the city, 45 mpg on the highway, and 37 mpg combined.

Those official fuel efficiency ratings are dead on with Ford's promise of achieving mid-40 mpg efficiency when it first announced the tiny three-cylinder engine in November 2012. Ford says that the Fiesta is the only subcompact in its class able to deliver 45 mpg on the highway while producing over 120 hp.

Ford says that its 1.0-liter Fiesta achieves fuel efficiency of 12 mpg higher than the Honda Fit and 8 mpg higher than the Toyota Yaris on the Highway. The 1.0-liter EcoBoost Fiesta gets better fuel efficiency than some competitors’ diesel and hybrid vehicles. Ford specifically calls out the 2014 Honda Insight, which achieves 44 mpg on the highway and the 2014 VW Golf diesel with a manual transmission that achieves 42 mpg on the highway.

Despite being incredibly fuel-efficient, the 1.0-liter EcoBoost engine reduces 123 hp and 125 pound-foot of torque. The vehicle also features an overboost setting allowing the car to make 145 pound-foot of torque for up to 15 seconds.

The 2014 Ford Fiesta with the 1.0-liter EcoBoost is set to hit dealer showrooms later this year.

Power per unit of displacement is not a useful measure of engine efficiency. It's like measuring CPU performance by performance per clock tick. "Who cares? What matters is performance per watt or total performance."

Power per unit of weight or or per unit of useable engine volume is much better.
For example, Corvette push-rod engines get much less power "per liter" than comparable DOHC engines, but push-rod engines are shorter and can be lighter, so Chevrolet is able to fit a more powerful engine in the same engine compartment than a comparable DOHC.
Thus, when

Wow, straight from GM's mouth. I bet that tastes nasty.

If OHV designs were great, everyone manufacturer would use them in their cars. The fact that GM and Chrysler are the only two in the world hanging onto them (and as I recall went bankrupt)...that should tell you something.

It sounds like you think that you've disputed what he said but in reality you only supported his argument. Do you realize this?
