Which is more fuel efficient, driving with a pickup's tailgate up or down?

Thanks to the smoke wand in the wind tunnel, you can actually see the difference in our video.
Should you drive with your pickup truck's tailgate up or down? It's an age-old controversy that's divided drivers for decades. Traditionalists will swear you should leave the tailgate down. Makes sense, right? It would seem to let the air flow more cleanly over the body and through the bed. But there's also a school of thought that argues trucks are designed to look and operate in a specific manner, and modern design techniques can help channel the airflow properly. So don't mess with all of that: Leave the tailgate up.

2015 Hennessey VelociRaptor 600 fills an F-150 Raptor-sized void

Ford is rumored to possibly debut a new F-150 Raptor at the upcoming Detroit Auto Show in January, but whether that's the case or not, Hennessey Performance is ready to fill the muscle truck niche now with its latest VelociRaptor 600 Supercharged based on the 2015 F-150. The fantastically named VelociRaptor package has been available on the regular Raptor for the past few years, taking power up to 600 horsepower or more, depending on what the buyer desired. With the latest one, the performance truck is now based on the aluminum-bodied F-150, specifically the FX4 Super Crew model with the 5.0-liter V8. "Having Ford's world-class new truck design, with a weight savings of nearly 700 pounds, our VelociRaptor 600 Supercharged will have an even greater level of performance and driving excitement," said founder John Hennessey in the company's release. The heart of VelociRaptor is the Roots-type supercharger running at 8 psi on the V8. With help from upgraded fuel injectors, a proprietary engine management system and stainless steel exhaust, it boosts grunt from a stock 385 horsepower to over 600 hp. To make sure that power gets to the road, the package also includes 33-inch BFGoodrich mounted on 17-inch Hennessey wheels. For buyers in need of more, the company offers optional parts including an off-road coilover suspension, different front and rear bumpers, a winch, LED light bar and Brembo brakes. Speaking to Autoblog, Hennessey said he feels confident that the latest VelociRaptor could do high-four-second sprints to 60 miles per hour, compared to the outgoing model in the low-five-second range. Prices for the VelociRaptor start at $73,500, which includes the donor F-150, and orders are open now. Actual deliveries should start by March at the latest, according to Hennessey. The company also plans to offer a similar package for EcoBoost F-150s later. Scroll down to read the full announcement about this muscle truck.

Ford evaluating new Fiesta RS?

Word coming in from across the pond has it that Ford is working on developing the business case to create a new Fiesta RS. The development is encouraged by the extremely positive reception the existing Fiesta ST has garnered to date, and the emergence of the above-pictured Fiesta RS WRC rally car, but it'll take more than goodwill to make a more extreme version a reality.
According to Auto Express, a new roadgoing Fiesta RS would almost certainly be based closely on the ST version, albeit with some vital differences. Its 1.6-liter turbo four would be increased from 180 horsepower to somewhere around 230 hp, and that powertrain would be accompanied by lightweight alloys inside blistered wheel arches, a stripped-out interior and possibly lightweight bodywork.
The vehicle's approval would reportedly require a strong business case in Europe, and not just in the UK where Ford hot hatches traditionally enjoy a strong following. It's unclear whether the Fiesta RS would potentially make the transatlantic voyage to American showrooms, but between it and the larger Focus RS, hopefully the Blue Oval wouldn't leave its home market out of the action altogether.
