I took my first road trip this weekend with our new 2013 SR5 and to be quite honest I think it is a dog, I had my wife and two of my kids with me with just bags for a weekend stay. I had a 2007 sport edition before this and I think that it would run circles around the 2013, I have searched and read about what others think and some are happy and some are not, sure it will run if you get on it and I understand Toyota's strategy for mileage but I think they just killed it when they wrote that flash file for the throttle, not enough torque, its just a mid to high rpm motor and on our way back we had bought some Christmas stuff and it downshifted to fourth on an uphill and then it downshifted into third and I thought it was going to float the valves. I really like some things about it but the powertrain I think is a step back. Your thoughts?
