Saying it over and over doesn't make it true. Go spend a few weeks
researching magazine road tests (don't just use EPA figures, they're
flawed badly). In real world driving, engine in today's cars makes
*very* little difference unless the driver is a consistent lead-foot.
There are even quite a few cases where moving up to the next engine size
will yield better mileage because acceptable performance can be achieved
with a lower (numerical) rear-end ratio, plus the bigger engines often
get an extra gear in the transmission too .
