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.

VW going turbo-only in 3 to 4 years

This really was a matter of when, rather than if. Volkswagen will apparently be the first manufacturer to phase out naturally aspirated engines in favor of turbocharging its full slate. VW is kind of responsible for ushering in this push towards small-displacement, turbocharged engines that's taken the industry by storm. When it dropped its direct-injection, 2.0-liter turbo in the 2005 GTI it demonstrated that strapping an iron long to an engine can enhance the powertrain as a whole. VW made fuel economy gains, while also giving a linear, non-laggy turbo experience that it has replicated, model-after-model, to this day.
Speaking with The Detroit News, Volkswagen's executive Vice President of Group Quality, Marc Trahan, told the paper that, "We only have one normally aspirated gas engine, and when we go to the next generation vehicle that it's in, it will be replaced. So three, four years maximum."
Really, it's hard to get teary-eyed about either of these engines going away. VW has access to smaller powerplants that could easily match the performance of the 2.5 five-cylinder and the 3.6 V6, while gobbling up less fuel and providing a better driving experience. What we are sad about is that a similar statement about the extinction of NA engines came from the Vice President of Powertrain Engineering at Ford, Joe Bakaj. We'd certainly get teary-eyed over a world without Ford's excellent 5.0-liter V8.

Now you can 3D print your favorite new Ford

Ford is letting people build their own cars, offering digital files so people can print 3D versions of their favorite models. This is way cooler than any old Matchbox or Hot Wheels toy. Ford this week started offering printable files for the F-150 Raptor, Shelby GT350R, Focus ST and Fiesta ST. Folks can order the 3D models in 1:32 scale in plastic (that'd make the mighty large pickup truck about eight inches long) but the digital files let users tweak the scale to the their liking. Once people have the digital files, they can print out their own miniature versions of the cars, made out of soft plastics, sandstone, and even some metals. Ford says it expects demand for such files to grow as sales numbers for desktop 3D printers surges to 1 million units in 2018. That's up from about 44,000 last year. Ford already offers digital files for its company logo, the 1.0-liter engine block, and two older Mustang models. But these new models take this to a totally different scale. Check out Ford's press release below. PRINT YOUR FAVORITE FORD VEHICLE AT HOME: FORD FIRST AUTOMAKER TO OPEN ONE-STOP 3D SHOP ONLINE - Consumers can now download digital images and 3D-printable files of Ford vehicles at the first-ever automaker-licensed, one-stop 3D shop online - The Ford 3D Store offers printable files of F-150 Raptor, Shelby GT350R, Focus ST and Fiesta ST; more models will become available later - Online store is powered by TurboSquid.com, the leader in providing automotive digital imaging and 3D-printable files Want to 3D-print a Shelby GT350R at home? Or would you prefer to simply purchase an F-150 Raptor 3D digital image for a presentation? How about both? Ford fans can now download digital images for Ford vehicles at the first-ever, automaker-authorized one-stop online store for 3D-printable vehicle files.
