UPDATE!!!
We have learned more about the upcoming F-150-based sport truck since the news about the Tremor broke this morning. While this isn’t a truck that was engineered by SVT like the Lightning was, the Tremor is a Ford sport truck said to be lighter than an F-150 SuperCab. In fact, according to sources at Ford, the rear-drive Tremor should weigh about 5080 pounds, making it about 130 pounds lighter than a SuperCab. Considering its EcoBoost engine puts out 365 hp and 420 lb-ft, the weight to power ratio in the Tremor should be fantastic, while not being too thirsty at the pump. (And the Tremor is the first short-wheelbase F-150 available with the EcoBoost.) While the Tremor uses the stock FX2/FX4 suspension, and isn’t an SVT truck, we certainly hope that if response is strong enough to this pickup, maybe Ford would consider creating a new EcoBoost-powered Lightning.

For those of you who never recovered when Ford discontinued the F-150-based Lightning performance truck, Ford has come up with an interesting alternative. It isn't called the Lightning, and it isn't officially a Lightning replacement, but this is as close as you will be able to get to a Lightning these days. It's called the Tremor, and it will go on sale in the fall as a 2014 model.

The Tremor is a regular-cab, short-bed F-150 (on the 126-inch wheelbase), powered by the 365-hp, 420-lb-ft, 3.5-liter twin-turbo EcoBoost, backed by a six-speed automatic. This is the first time Ford has offered this combination, and we expect it's going to be a popular option. The Tremor will be offered as a rear- or four-wheel-drive truck, with the same suspension setup as the FX, and a 4.10:1 rearend and electric locking rear differential will be standard. The Tremor will be treated to the FX appearance package, and its seats are from the FX trucks as well -- as in the FX, the Tremor's sport bucket seats have Alcantara inserts. This will be the only regular-cab F-150 Ford offers with a flow-through center console and floor-mounted shifter.

The Tremor will enter the marketplace as the Harley-Davidson Edition exits. That the company is moving to a special-edition truck powered by the EcoBoost instead of the 6.2-liter V-8 does mean that fuel economy will be higher; it also means the Tremor should cost significantly less at the dealership than the Harley did.

As of this writing, the fastest current-generation F-150 we have tested was the rear-drive EcoBoost-powered SuperCrew, which hit 60 mph in 6.2 seconds. For perspective, the last Harley-Davidson F-150 we tested went 0-60 in 6.4 seconds. Considering the Tremor will be offered as a rear-drive truck, on a shorter wheelbase, and will weigh less than that SuperCrew, we anticipate the new model could easily hit 60 in under 6 seconds. That's not quite as fast as the Lightning was, but it's in the same neighborhood. As soon as we can take one to the track, we'll let you know how fast the Tremor is.
