This made me chuckle:

So, the 2,900-pound tech-laden 2009 Honda Civic EX is about 32-percent heavier than the scrappy and eager 2,200-pound 1992 Civic EX. But at 34 highway mpg and 41 highway mpg, respectively, there's only a 17-percent deficit in fuel economy. Pound for pound, I'd say the 2009 engine is more efficient.

Using his figures:
'92 Civic: 41 mpg / 2200 lbs = 0.019 mpg per lb
'09 Civic: 34 mpg / 2900 lbs = 0.012 mpg per lb
"Pound for pound, I'd say the 2009 engine is more efficient."
Nuh uh!
