It has an 8 speed automatic transmission.

What a difference compared to the Kia's 5 speed automatic tranny.

Given my personal experience w/ upsizing to lower rpm and the joy of driving an 8 speed, I can't understand why the industry has been so slow in increasing the gearing in their eco-models.

I remember the 1984 corvette had the first 6 speed and got 27mpg on the hwy all day long.

I really thing 6-8 speed auto trannies are the secret to improving mpg.
I'm so much thinking the same way about gearing!! upsized tires on my car 1.5 inchs higher than stock enjoying the lower rpms on my drives.
