But when a 2.2L I4 in a sub 3000 lb car gets nearly about the same fuel economy of a 6.2L Corvette, there is something seriously wrong.

To be fair...the Corvette is the slipperiest car they build short of the Volt, and it's geared REAL low thanks to the available torque in such a light car. 2.73, iirc...
