The 2014 Ford F-150 Tremor pickup goes on sale in the fourth quarter. It's a high-concept version of the pickup geared to “street truck enthusiasts,” per Ford. The vehicle is the 11th pickup in the F-150 lineup. Ford said the truck is geared to sporting enthusiast buyers who don’t necessarily use their pickups for work. The Tremor will be something like a new version of the Lightning, a performance street truck Ford sold from 1993 to 2004. The Lightning was once rated the world’s fastest production pickup.
