Its a good thing you'll have all those horses when you turn it over to quickly make you forget what it cost to fill the gas tank

...and don't you have a 5.3L V8 in your Impala?

Does it not get better gas mileage? Especially on the highway?

Not by much. Actually I'd be surprised if it gets better in city driving. I think SS Impala's get like.. 16MPG city? A whopping 1MPG better then my mom's truck.
Actually I lie. I was thinking about traditional F-150's. The Lightning probably tops out at like 15 highway. Nonetheless, I'd bet a 4.6L equipped F-150 or the ne w'09 SFE could probably out-MPG an Impala.
