STI Gearing is stupid short as well; and technically the roots of this powerplant are what, 15 years old? It gets 17-18 in Summer mixed, but winter blend is definitely no bueno.16mpg? Really. Thats horrible.
Even the RS is averaging 19.8mpg over the last 3 months on Fuelly, and 20.5mpg average lifetime. And I usually drive like a speed demon on the highway which the RS hates because of its short gearing.
