American automakers fall in latest Fortune 500 rankings

Not that it means anything beyond bragging rights, but if you're fixated on the positions of domestic automakers on the annual Fortune 500 list, both General Motors and Ford are still on it but they've slipped a couple of notches. The list ranks American companies and they're ordered solely by revenue. GM, fifth last year, came in seventh, while Ford fell from ninth to tenth even though both companies saw small gains in annual revenue.
GM's $152.3 billion in revenue was less than a third of that of the first company on the list: Wal-Mart, which regained the title from Exxon Mobil. Berkshire Hathaway and Apple are the firms that moved GM down. Ford, displaced by energy company Valero, had $134.3 billion in revenue.
On a side note, profitability isn't a factor, but both GM and Ford were down in this year's list compared to last year's: GM declined from $9.2 billion to $6.2 billion, Ford fell from $20.2 billion to $5.6 billion. If profits were included, Exxon Mobil would probably still be king: although the energy company made almost $20 billion less in revenue than Wal-Mart's $469.2 billion, it posted $44.9 billion in profit compared to Wal-Mart's $17 billion.

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.

2016 Ford Focus RS shows up in Geneva, still bound for America [w/video]

Representing the super-hot hatchback movement at the 2015 Geneva Motor Show, we have the 2015 Ford Focus RS, the third-generation to wear the performance-focused designation. Bound for America for the first time, it's fair to say we're darn excited for the Focus RS and its 2.3-liter, turbocharged four-cylinder. With at least 315 horsepower under the hood and the long-awaited inclusion of an all-wheel-drive system, there's little arguing that the RS will be seriously quick off the line. It should be darn good through the bends, too. The all-wheel-drive system packs a Dynamic Torque Vectoring Control system that sends up to 70 percent of the power to the rear axle. On top of the AWD's torque vectoring ability, the Focus RS adds a brake-based torque vectoring system, which transfers power laterally, as needed. Michelin Pilot Sport Cup 2 tires should only help keep the RS glued to the tarmac. A three-pedal setup is the sole transmission option, which should delight purists. According to Ford, both the clutch and the trans itself have been bolstered to handle the 2.3-liter's power. Ford also comprehensively upgraded the looks of the Focus RS relative to the lesser Focus ST. Its enormous rear wing and the back bumper's rear diffuser complement the car's menacing face. The ST's center-exit exhaust has been ditched for a meaty set of pipes, while the car on display in Geneva shows off a different set of alloys than what we saw during the car's original debut.
