This is on my 2012 I ordered and bought this truck to be my winter driver. I picked it up in May and only drove it a couple hundred miles during the warm weather and the hybrid tech seemed to work just fine . As I put my other vehicles in storage and the weather got cold, the hybrid tech only kicks in after driving for 15 minutes or more, which is an issue since I only live 5 minutes from work. So the main reason on buying this truck and giving up on several options because of the hybrid, doesn't even work during conditions for which I bought it for. Because of the hybrid, I couldn't order a rear sliding window, storage under the rear seats, heated seats, bigger wheels, interior choices were limited just to name some. And i ordered every option and highest package possible except for a sunroof. Advertised mpg is 21, but only getting 17. After knowing all of this I would have ordered a different truck or even a different make of truck. This rating is so low just because the sole reason of purchasing this truck in a hybrid is completely useless for my driving needs. The truck does perform well in snow as far as traction so at least that is good. Hybrid also causes you to give up towing capacity, but 99% of the time for me I'm not towing large loads.
This is a 1500 series truck that comes with a 6.0 and an electric motor built into the transmission. It is smooth and powerful. It is very quiet and well balanced. I find that I can drive through the neighborhood in pure electric mode. When I am driving 50mph or less at a constant speed, it is in v4 / electric mode. I have noticed great gas milage for daily driving. Once you are pulling trailers or going 70+, it is the same as any gas engine, but it also takes much more power to move at that speed. The interior is convenient and adding things like trailer brake controllers and aftermarket dvd is very easy as long as you buy the kind designed for that car! I enjoy this truck and my carmax experience is always great.
