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.

Here's how much the new Ford Mustang will cost in Germany

While you can find Ford Mustangs across Europe, they were brought over there courtesy of importers, rather than Ford itself. That's changing with the 2015 pony car, as Ford will be selling it directly through its overseas dealers. Now, we know how much German customers will be shelling out for the muscle car, courtesy of the maniacs at Mustang6G. Not surprisingly, there's a fairly hefty premium compared to US prices. The base Mustang, with its 2.3-liter, turbocharged four-cylinder and six-speed manual transmission will start at 34,000 euros ($40,214, at today's rates), while the 5.0-liter V8/six-speed-manual model starts at 39,000 euros ($46,127). The Mustang Convertible demands an extra 4,000 euros ($4,731) while the optional six-speed automatic elevates the price by 2,000 euros ($2,365), regardless, in both cases, of whether there are four or eight cylinders under that long hood. While those prices are certainly pretty dear compared to what we pay in the US, the Mustang is a genuine bargain compared to some of Europe's other sports coupes. The German market BMW 4 Series starts at 36,050 euros ($42,638), while a base 435i calls for 48,100 euros ($56,891). It's a similar story with the Audi A5/S5. As for the Mustang's arch-nemesis, the Chevrolet Camaro, which is only available with the SS model's 6.2-liter V8, starts at 39,990 euros ($47,298), comparing quite evenly with the 5.0-liter GT.

MotorWeek remembers pre-EcoBoost Ford with the Thunderbird TurboCoupe

Sometimes it feels great to embrace nostalgia for a trip down memory lane, and MotorWeek indulges that occasional desire with its regular Retro Review series. This time, the long-lived show goes back to the '80s to check out two of the top performance vehicles in the Ford lineup at the time – the 1987 Thunderbird TurboCoupe and Mustang GT. Both models had just received thorough refreshes after several years on the market. Long before an EcoBoost badge ever met its models, Ford made early forays into experimenting with turbocharging on vehicles like the T-Bird TurboCoupe. Based on MotorWeek's assessment, the company was on the right track. The boosted 2.3-liter four-cylinder was apparently a bit coarse but offered 190 horsepower with little turbo lag, compared to 155 hp the year before. The Mustang GT is likely the more-fondly remembered of these performance Fords today and provides an interesting point of comparison against the TurboCoupe. MotorWeek found some faults with the 'Stang, though. While it was quick for the time with a sprint to 60 mph in 6.5 seconds, the 'car was described as "a nose-heavy beast" for its handling. And for a look at Ford's future in turbocharging – the GT will have an EcoBoost powerplant – check out our Related Video:
