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 lowers MPG ratings on six vehicles

Ford has announced that it will be lowering the fuel economy ratings on a number of its 2013 and 2014 model year vehicles after an error was discovered in the company's internal testing data. The EPA has been notified.
Worryingly for Ford, the vast majority of the vehicles affected are hybrids, including the C-Max, Fusion and MKZ in both hybrid and plug-in varieties (where applicable). Also covered as part of the rerating is the entire lineup of 2014 Fiesta engines, with the exception of the ST, including the turbocharged, three-cylinder EcoBoost.
The C-Max was originally rated at 47/47/47 mpg, but dropped to 43/45/40 last year and now to 40/42/37.

Ford spotted testing new Fiesta RS hot hatch

There's a lot to love about Focus ST and Fiesta ST, but if neither of those is enough for you, we've got good news: Ford has even more potent RS versions of both in the works. The Focus RS we already saw last month, but here we have our first spy shots of the smaller Fiesta RS undergoing testing. Spotted alongside still-camouflaged prototypes of its big brother, the new Ford Fiesta RS is wearing a modified front end, flared fenders packing a wider track and a revised rear-end. The beefed-up bodywork is all well and fine, but we're looking forward to finding out what's underneath it all. Sources point towards a 250-horsepower version of Dearborn's 1.6-liter EcoBoost turbo four, along with upgraded brakes and suspension. The big question, though, is whether the production Fiesta RS will pack the new performance all-wheel-drive system from its larger counterpart, or stick with front-drive and some sort of clever diff. It may be too early to tell, as this pocket rocket is likely a good year away from its debut, but in the meantime you can scope out the spy shots in the slideshow above for a taste of what's to come.
