I was impressed too, but AutoWeek probably got it wrong. 
The official news from the Honda site is that the 2006 engine is 20% more powerful and 5% more efficient. The regen mode is 10% more efficient. The CD factor is better too. The rated fuel efficiency of the new Civic will certainly be better than a 5% improvement (as the factors add)but probably less than a 20% improvement.
