Ford recalling select Taurus, Explorer and Lincoln MKS models over fuel tanks

Ford is recalling certain 2012 Taurus, 2013 Explorer and 2012 Lincoln MKS models over fuel tank concerns. According to the National Highway Traffic Safety Administration, vehicles built between July 19, 2011 and March 15, 2012 may have been built with fuel tanks that have a "marginally sealed seam" on the side. Those seams may not provide the strength necessary to protect the tank from rupture during a collision. They may also leak. The recall covers a total of 3,037 vehicles. NHTSA says that leaked fuel, in the presence of an ignition source, could easily cause a fire.
Dealers will inspect the tanks and replace them as need be free of charge. Owners can expect to be notified once the campaign begins on or around April 22, 2013. You can read the full NHTSA recall notice below for more information.

Hennessey completes first VelociRaptor SUV conversion [w/video]

Start with a Ford F-150 SVT Raptor as your base vehicle for modification, and chances are high that you'll end up with something pretty cool. Now, have those modifications done by professional lunatics Hennessey Performance, make the project turning the pickup into an ultra-long SUV, and the result stands a real chance of being a total kick in the ass. Let us present the Hennessey VelociRaptor then, in all of its awesomeness.
Hennessey has taken care in grafting a "Expedition style" rear cabin onto the Raptor, complete with an optional third row. The pictures we have show a cabin that's up to the fit and finish standards of the original Ford truck, too. The cab added over the bed also makes room for a massive load space out back, accessible via split out-folding doors and long enough for a person to lay down in (see video).
Mechanically, the truck-turned-SUV sticks with Ford's stock 6.2-liter V8, rated at 411 horsepower, or can be had with a supercharger and some 600 hp. Hennessey says the stock-motor VelociRaptor will run from 0-60 miles per hour in 7.5 seconds, while the hi-po version takes just 5.9 seconds. The SUV does take some of the off-road ability away from the Raptor, with the company saying it hasn't yet had the opportunity to test its capabilities. On-roading and "moderate off-road duties" are the current prescription.

A cool boost to turbocharger performance

Since the advent of the forced-induction engine, we have been looking for ways to get every drop of performance we can. There are many approaches to getting additional power using better intercooling, water injection, or even adding nitrous oxide. One take on a short instant burst of power is being researched by Mahle and involves providing supercooled air to an engine, which allows it to burn a leaner fuel mixture and produce more power. The supercooling idea is not new and was examined by Ford in 1993 on the Mustang Mach III concept car, then brought up again in 2003 with the SVT F-150 Lightning concept. Ford called its system the SuperCooler; it was designed to work with any turbocharged or supercharged engine equipped with a water-to-air intercooler. The system on the Lightning concept used a small tank of antifreeze that was hooked up to the truck air conditioning compressor. The air conditioning compressor cooled the antifreeze down to about 30 degrees. The other side of the tank was hooked up to the air-to-water intercooler, which usually had a temperature over 100 degrees. Once the antifreeze was circulated from the tank into the intercooler, it would lower the intercooler temperature and provide for a cooler, denser air charge into the engine; the result was around 50 extra horsepower for a burst of about 30 seconds to a minute, depending on the size of the tank. The system for the Lightning was to be offered as a $750 option and would have been targeted towards drag racers and the like, as it could be used for a run down the drag strip and then re-cooled by the time the truck was back in line. The system was fairly non-intrusive – it only weighed about 25 pounds and did not require a new compressor or intercooler. But as with many concepts, it was ultimately scrapped. The technology was always stuck in the back of my mind, but with larger and more powerful engines being produced it could not find its place. With the advent of new fuel economy standards, we have seen small-displacement turbocharged engines pop up and they seem like the perfect candidate for this type of technology. Ford's EcoBoost 1.0-liter three-cylinder turbocharged engine, as used in the Fiesta and Focus, is one such candidate for this technology. It would add a negligent amount of weight but could provide a boost of 10 to 20 horsepower when needed, like merging onto the highway or catching up to traffic.
