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.

New Forza 6 car pack will let you race the Pontiac Aztek

Just in time for this weekend's Rolex 24 Hours of Daytona, the new Alpinestars Car Pack for Forza Motorsport 6 on the Xbox One lets you slip into the driver's seat of last year's winner. If you want to take something much weirder for a spin, the collection also includes a 2005 Pontiac Aztek. The download is available now for $6.99. The Ford #02 Chip Ganassi Racing Riley Mk XXVI Daytona was in a four-car battle early in last year's race, but it eventually was victorious. Forza Motorsport 6 also challenges drivers who download the car to a new Rivals event around Daytona, and the fastest people could win Alpinestars prizes. If you're nostalgic for a classic Daytona racecar, this pack includes Mercury #15 Whistler Radar Cougar XR-7. The V8-powered beast won the IMSA GTO class in the 24-hour event in 1990. It should be fun around the game's longer road courses like Road Atlanta. This collection also has an eclectic mix of vehicles that aren't racecars. The controversial Aztek and the equally-controversial 1996 Subaru SVX take their places beside a lineup that offers drivers three eras of performance cars – a 1967 Sunbeam Tiger, 1974 Toyota Corolla SR5, and 1992 Alfa Romeo Milano Quadrifoglio Verde. The video below shows all of them in action. Race to the Finish Line with the Alpinestars Car Pack for Forza Motorsport 6 By Xbox Wire Staff posted on January 27, 2016 at 8:00 am With the racing season set to kick into full gear during this weekend's Rolex 24 Hours of Daytona race, Forza fans now have a chance to get their own taste of endurance racing glory with the Alpinestars Car Pack for Forza Motorsport 6, available on Thursday, Jan. 28. Leading off the pack of seven cars is last year's 24 Hours of Daytona winner, the 2015 Ford #02 Chip Ganassi Racing Riley Mk XXVI Daytona Prototype. The prototype will be fielded in this weekend's race, which begins at 2 p.m. EST on Saturday, Jan. 30 and can be viewed live on Fox Sports 1 in the U.S. The Alpinestars Car Pack features six additional cars, each with a unique pedigree all its own. From the 1990 Mercury #15 Whistler Radar Cougar XR-7 – also a competitor in Daytona 24 Hour events of years past – to the inimitable 2005 Pontiac Aztek (famous more for its fictional owner than its performance), this pack has something for every kind of car fan. Forza Motorsport 6 is the only game where players can drive last year's Rolex 24 Hours of Daytona winner on the recently remodeled Daytona International Speedway.

Junkyard Gem: 1955 Mercury Montclair Coupe

I find plenty of 1950s Detroit vehicles in the big self-service car graveyards I frequent, but most of them are fairly ordinary sedans that never stood much chance of getting fixed up and put back on the road. Such is not the case with today's Junkyard Gem, which is a top-trim-level, heavily optioned hardtop coupe from one of the most desirable model years of the tailfins-and-chrome postwar era. Nearly every Mercury model ever made was a Ford model with some cosmetic changes applied, and the '55s looked very similar to their mechanically identical Ford brethren. In 1955, the new Mercury came in three trim levels: the entry-level Custom, the medium-zoot Monterey, and the glitzy Montclair. Each was available as a hardtop coupe and four-door sedan, with wagon versions of the Custom and Monterey. The Montclair could be purchased as a convertible or with the wild "Sun Valley" glass roof. The Montclair got its own line of hallucinogenic two-tone interiors, in order to make the daily lives of Europeans feel even more gray and penurious (the UK only dropped food rationing in 1954, and the two Germanies were still clearing the rubble of their blown-up cities). This car's upholstery has been bleached by decades of sitting outside in the harsh High Plains climate, but it started out as vivid red and white "Chromatex" fabric. The list price on this car was $2,631, or about $29,200 in 2022 dollars. The Sun Valley and convertible Montclair each cost $2,712 ($30,100 today). Ford didn't offer a corresponding hardtop coupe in 1955, though the Fairlane Crown Victoria two-door did look extremely snazzy (and cost a mere $2,302— $25,545 now— with the same V8 engine as the Monterey). Meanwhile, Oldsmobile offered the handsome 88 Super Holiday Coupe for $2,714, though the Montclair had the more powerful engine. Oldsmobile had been selling new cars with overhead-valve V8s since the 1949 model year, while Ford didn't ditch the Model A-era flathead V8 for new U.S.-market cars until the 1954 model year (you could buy a new Simca Esplanada in Brazil with an Ardun-headed Ford V8-60 all the way until 1969). GM's Chevrolet Division got all the press in 1955 with the introduction of the brand-new small-block V8 engine, but Ford's 292-cubic-inch (4.8-liter) Y-Block V8 made more power than the 265-cube (4.3-liter) Chevy and the 324ci Olds Rocket 88.
