2014 RAM, 5.7 with 8 speed and 3.91 gearing gets avg. 17-18 in the city.
2006 300C SRT8 6.1 with 5 speed NAG1 has a lifetime avg. of 17, everything from city driving to road course track days.
Fleet vans: 3500 Savanas and Express's, all 6.0 gas with 6 speed and either 3.42 or 3.73 gears cannot be clocked due to many hours of stationary operation! Curiously the trip computers all say around 6.
Silverados: only a couple around anymore, both are 5.3 with 3.73 gears. They get 15-17 depending on who's driving.
