2015 Ford Focus ST zooming toward Goodwood reveal [w/video]

Ford has quite a party ready for the Goodwood Festival of Speed starting on June 27. Not only is the 2015 Mustang going to be driving in front of the European public for the first time, the Blue Oval is also unveiling its 2015 refresh for the Focus ST.
Official details about the latest Focus hot hatch are practically nonexistent at this point. Ford's teaser image shows narrower headlights, and the company says that the ST also benefits from the technical and quality improvements from the refreshed standard model, which likely means an even more Aston-Martin-like grille. However, any improvements for the power or handling are a mystery for now.
Ford will even give visitors to the festival the chance to drive the new ST - at least virtually. Gran Turismo 6 kiosks will be on hand with the hot hatch loaded up to race the Goodwood Hill Climb. There will also be real-time races between former Stig Ben Collins in the real ST challenging a player up the hill in the game.

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.

2015 Ford Mustang EcoBoost flogged and analyzed by Ignition

Aside from the way it looks and perhaps its independent rear suspension, the biggest bit of news on the 2015 Mustang may be the inclusion of its 2.3-liter, turbocharged four-cylinder engine. That blown mill marks the first time since the Mustang SVO of the '80s that a turbo has been fitted under the engine of Ford's pony car.
The Mustang EcoBoost is the subject of the latest episode of Ignition from Motor Trend, giving us a great look at the technical, nitty-gritty side of the turbocharged coupe. Covering it from bow to stern, host Carlos Lago walks us through the boosted Ford before taking to the track for some driving impressions, with particular praise given to the low-end grunt of the 2.3-liter mill.
Check out the full video and then let us know which 2015 Mustang has your interest piqued the most - the EcoBoost four, the 5.0L V8 or the entry-level V6.
