Ford spotted testing new Focus RS at the Nurburgring

Ford is expected to be launching a revised version of the Focus ST soon, but the latest snapshots from our spy photographers at the Nürburgring suggest that the Blue Oval is already working on an even more potent example: the new Focus RS.
Though the partially disguised test mule is wearing an ST badge (along with a Dewey sticker that makes us wonder what adventures Huey and Louie are up to and what manner of duck-tail rear spoiler they may be wearing), there are several tell-tale signs that something else is afoot here. There's a larger front air dam, bigger brake calipers, dual exhaust tips (instead of the central exhaust on the ST) and a reshaped wing protruding from the trailing edge of the roof.
That may all be well and fine, but what's under the hood? We don't know yet for sure, but word has it that Ford is preparing to port over the 2.3-liter turbo four offered in the new Mustang, where it packs 305 horsepower and almost as much torque - potentially retuned to produce even more for the top-of-the-line Focus, which could channel it all to the front wheels like the last model or pack an all-wheel drive system. The Global C platform on which the Focus is based does, after all, also underpin AWD models like the Ford Escape and Lincoln MKC.

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.

How the Ford F-150 SVT Raptor became a reality

The camouflaged Ford F-150 SVT Raptor prototype captured above blazing its way across the desert during a test run left company engineers giggling in amazement, reveals Jamal Hameedi in a new Autoweek video. Ford's global performance vehicle chief engineer, accompanied by senior exterior designer Bruce Williams, sat down with the publication to discuss the concept and development of the automaker's super off-road F-150.
Designing a high-performance pickup in 2008, right when the cost of gasoline was going through the roof, seemed insane at the time, but the team pushed forward with the innovative vehicle regardless. The interview includes plenty of Ford B-roll footage as visual candy, and the conversations include discussions about exterior design, ride comfort, anti-lock brake tuning, suspension engineering, weight reduction and why it was necessary to make the Raptor visually different than Ford's standard F-150. The model's origin story is very interesting, and you can learn more about it by watching the video below.
