Ford's new Focus RS hatches hot and heads for America

The hot hatch market is heating up, and heating up fast. What you see here is Ford's new challenger for pocket-rocket supremacy, the third iteration of the breed and the 30th model to wear the Rallye Sport designation. But perhaps best of all, it will be the first time Ford will offer a new Focus RS in America. Following yesterday's leak, the latest Ford Focus RS is now ready to step out into the light and light up its tires. Answering the call is the same 2.3-liter EcoBoost turbo four as you'd find in the new Mustang, but upgraded with a new low-inertia twin-scroll turbocharger, larger compressor and intercooler, freer-flowing intake, large-bore dual-pipe exhaust with electronically controlled valve and upgraded internal components. The result is a 6,500-rpm redline (closer to that of Ford's atmospheric performance engines) and an output quoted as "well in excess of 315 horsepower" – which is already 5 more than the EcoBoost Mustang and a good 63 more than the existing Focus ST. Power is transmitted to the tarmac through a new performance-focused all-wheel drive system with torque vectoring that can send as much as 70 percent of available twist to the rear wheels (and as much as 100 percent between them). The system works in tandem with the brake-based torque vectoring system and stability control, and will even divert torque to the outside rear wheel under cornering to keep it flat and under control while reducing understeer. Those still suspicious of dual-clutch gearboxes will also be pleased to read that Ford has stuck with a conventional six-speed manual. We'll reserve judgement on the inclusion of the electric power steering until we get a chance to drive it, though. Of course the small team of global Ford Performance engineers who developed the new Focus RS – and the Gymkhana legend Ken Block who consulted on the project – didn't just tinker with the powertrain and leave it at that. The suspension features stiffer spring rates, bushings and anti-roll bars than the Focus ST, augmented by two-mode switchable dampers. 19-inch alloys wear Michelin Pilot Super Sport rubber, with optional Pilot Sport Cup 2 semi-slicks for track-day enthusiasts. Ford has yet to detail the brakes on its new hot hatch, but you can bet they've been upgraded as well.

Ford finds flex-fuel engine design plays big role in emissions output

How bad is ethanol for your engine? There's been a lot of debate on this issue as the US considers upping the biofuel content in the national gasoline supply from 10 percent (E10) to 15 percent (E15). The ethanol industry and some scientists say higher ethanol blends show no "meaningful differences" in new engines while the oil industry says ethanol creates health risks. Researchers working at the Ford Research and Innovation Center decided to take a closer look at how a wide range of gas-ethanol blends - E0, E10, E20, E30, E40, E55 and E80 - affected the emissions coming out of a flex-fuel 2006 Mercury Grand Marquis. To see the full report, printed in the journal Environmental Science & Technology, requires payment, but there is an abstract and Green Car Congress has some more details. The gist is that, "with increasing ethanol content in the fuel, the tailpipe emissions of ethanol, acetaldehyde, formaldehyde, methane, and ammonia increased." At least NOx and NMHC emissions decreased. The researchers say that the effects are due to the fuel and "are expected for all FFVs," but that the way that a manufacturer calibrates the engine will affect NOx, THC, and NMOG emissions. It's this last bit that's important, since the researchers found, "Higher ethanol content in gasoline affects several fundamental fuel properties that can impact emissions. ... These changes can have positive or negative effects that can depend on engine design, hardware, and control strategy. In addition to direct emissions impacts, higher ethanol content fuel can also provide more efficient combustion and overall engine operation under part-load conditions and under knock-limited higher-load conditions." So, as we head towards more ethanol in our fuel supply (maybe), manufacturers are going to need to learn how to burn it most efficiently.

Jay Leno drives postcard-perfect '32 Ford Highboy Roadster

At the turn of the century, it was arguably the Honda Civic that best defined inexpensive performance tuning, and in the '50s it was the Tri-5 Chevys. One of the earliest platforms to gain a huge following among young people looking for a cheap way to go fast was the classic '32 Ford Highboy Roadster. This week, Jay Leno's Garage looks at one of the very first vehicles that defined the look of the hot rod heyday.
This '32 Ford was built in the '40s and graced the cover of the fourth issue of Hot Rod Magazine back in 1948. All of the hot rods that you see shining at car shows today owe a serious debt of gratitude to this roadster. It bears all of the cues that define the look, including a notched frame and hidden door hinges. Under the three-piece hood is a flathead V8 boasting all sorts of period modifications, including copper cylinder heads. It was seriously fast in its era too, and proved it by reaching 112.21 miles per hour on a dry lakebed in 1947.
These days, this hot rod is on display at the Petersen Automotive Museum. Although, if you can't make it to California to see it, the United States Postal Service is celebrating this Ford with one of its two hot rod Forever stamps. Like Jay says in the video, in terms of hot rodding, "it all comes back to this." Check out the video to learn more about this rolling piece of tuning history.
