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 Review

"It's just a V6 Mustang." That phrase, so often spoken with derision and disdain, has haunted owners of Ford's more affordable and economical pony car since roughly April of 1964. Even after Dearborn finally paid some attention to its entry-level muscle car by eliminating telltale V6 features – the company fit dual exhausts in place of the single-exit pipe in 2011, negating the budget offering's biggest visual giveaway – the car was still hard pressed to shake its reputation as a hairdresser's car and rental fleet queen. For the Mustang's 50th year in service, Ford went back to the drawing board, we think with the distinct goal of eliminating the stigma of the non-V8 Mustang. While the V6 is still being offered (your local Avis and Enterprise lots wouldn't be the same without them), it's best to think of the new, four-cylinder, turbocharged Mustang EcoBoost as the entry-level model. But will the addition of forced induction – from an engine that will see action in the upcoming, enthusiast-centric Focus RS, no less – be enough to appease those pony car fans that believe that only Mustangs with eight cylinders are worthy of the galloping stallion badge? After a week at the helm, we certainly think it is. The new Mustang's looks have been covered ad nauseam. Chances are good that you either love the fastback styling, or you think the original pony car now looks a lot like a Fusion Coupe. We'll ignore the bigger styling remarks for the 2015 Mustang, and instead, focus on what's done right with the EcoBoost model. Like the V6 before it, certain boxes are correctly ticked. Dual exhausts? Check. 18-inch alloys? Check. (Our EcoBoost Premium model even shares its wheels with the base GT). HID headlamps? Check. Up front, there's a surprisingly meaty chin spoiler while the muscular lines of the 'Stang's long hood tie in nicely with the fastback shape, which terminates in a neat rear spoiler. There's even a body-colored diffuser at the back, between the chromed exhaust tips. The bottom line is, unless you're a true Mustang aficionado, you'll be hard pressed to tell the difference between the turbocharged car and its 435-horsepower brother. Simply sitting in the redesigned cabin isn't enough to give the EcoBoost away, either. The leather-trimmed seats (standard on the Premium trim) are cozy and supportive, with plenty of bolstering to help keep both driver and passenger in place while the 'Stang exhibits its newly enhanced cornering abilities.

Jay Leno sees how the other half lives with CHP cop cars new and old

Comedian Jay Leno is changing gears from driving fast cars to checking out some of the police cruisers that regularly chase down and dish out punishment to those fast cars. In this episode of Jay Leno's Garage, we get the lowdown on the modifications made to the Ford Explorer for the Interceptor package (which looks pretty tough in its California Highway Patrol livery).
The new Ford is cool, but cooler still are the pack of classic CHP cars that Jay has along for the episode. A 1982 Mustang, 1966 Dodge Polara, 1970 Mercury Monterey and 2000 Crown Victoria are all in the shop. Better still, Jay lays out an argument for ones of the classic cruisers as the best cop car of all time. Get your guesses in now, and then scroll down to watch and learn.
