Drove my gf 2011 Lexus RX 350 for several days this week.
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.
