If you don't like the idea of the SCV-6 that is fine, but this engine mated to the 8 speed tranny will get the job done. There is no lack of power with the benefit of high altitude performance for those of us that need it. 19 mpg at 70 on the highway (flat road) doesn't hurt either. Even if the MPG only goes up by 2, this increases the range 44 miles, which is My main drawback to this otherwise spectacular vehicle.
