[QUOTE="codeman, post: 1568432, member: 45090"] I understand, and you're correct that they are used in completely different applications. However, my main point is still valid. Even considering the same or very similar application, there's a noticeable difference between ACTUAL mpg, and EPA rated or manufacturer claimed MPG. We all know, those MPG figures on turbo boost engines are performed with an "expert" driver who knows to stay out of the boost range as much as humanly possible. You sound like you know engines, and vehicle dynamics well so that point should still ring valid and true with you. I mentioned the V8 with ~560 lb-ft of torque would also presumably anyhow, be mated to a noticeably lighter vehicle overall which given solid engine design (something like the 5.2 Predator) would also be smaller displacement, plus using a 10 speed transmission should overall give a noticeable increase and not 'within the same' fuel economy as a much heavier TRX with a clunkier 8 speed transmission & driveline. I'm pretty confident Ford would also be very clearly targeting a fuel economy that's still good-enough to not be outrageous for everyday driving; something I think the RAM missed the boat on a bit with the TRX despite the obviously awesome sound and acceleration :) [/QUOTE]
