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.

Ford Focus Electric gets $6,000 price drop, now starts at $29,995

In early 2013, the Nissan Leaf shed a massive $6,500 from its $35,200 base price to offer a new starting price of $28,800. Since then, we have seen numerous other plug-in vehicles get smaller price tags, from the Honda Fit EV (lower lease price) to the Chevrolet Volt (around $5,000 lower) to the Mitsubishi i (a $6,130 drop). Last year, Ford lowered the $39,200 price of the Focus Electric by around $4,000, but that hasn't been enough to get the Ford EV to really compete, saleswise, with other plug-in vehicles on the market. But wait, as they say, there's more. This past weekend, Ford lopped another $6,000 from the price of both the 2014 model year Focus EVs currently on dealer lots as well as the redesigned 2015 models that are now rolling out (they're basically the same car, minus some appearance changes). Ford spokesman Aaron Miller confirmed to AutoblogGreen that the Focus EV will now start at $29,995 and said that reducing the price should make the Blue Oval's only pure EV competitive. "We hope by reducing the price we're giving consumers another reason to consider it," he said. Through the end of September 2014, Ford has sold just 1,534 Focus EVs in the US (the model sold 1,335 in the first nine months of 2013). For comparison's sake, the Nissan Leaf starts at $29,010 and sells around 3,000 units a month in the US. Miller notes that the Focus EV has been selling the best on the West Coast, and is also doing well on the East Coast. After that, he said Atlanta and the Great Lakes area also see decent sales of model's admittedly small pie. We can only assume that offering the EV for under $30,000 will make that pie somewhat bigger.

Saleen previews new 302 Mustang

The introduction of a new generation of a model like the Ford Mustang may be exciting enough in its own right for enthusiasts, but that's just the tip of the proverbial iceberg, because you know that Ford itself as well as numerous aftermarket tuners will soon follow up with even more desirable versions. And few Mustang tuners carry quite the same clout of Saleen.
Recently reunited after its previous split, Saleen is back on the map and hard at work on new aftermarket modifications for a wide array of muscle cars. We knew it would only be a matter of time before it would release a new 302 Mustang, and now it's sent out the first image to show us what to expect.
Details are scarce, but House that Steve Built says the 2015 Saleen 302 Mustang "is perfectly positioned as the next American exotic." And it should know, considering that it's the same outfit that produced the Saleen S7 that really was a true American exotic. From the teaser image above we can see that Saleen has given its Mustang a new front air dam, a very wide air scoop on the hood and of course Saleen's trademark slat grille.
