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 Roush Stage 3 Mustang has 670 hp

My last speeding ticket was nearly two years ago while behind the wheel of a 2014 Roush Stage 3 Mustang. Considering the supercharged 5.0-liter V8 produced 575 horsepower – the lowest of the Stage 3's tunes – an encounter with the friendly folks at the Michigan State Police seemed inevitable. With the 2015 Stage 3 producing 95 more horsepower, if and when I drive the new supercharged 'Stang, another meeting with Michigan's finest seems likely. The combination of the Ford 5.0-liter V8 and a 2.3-liter TVS supercharger turns out 670 horsepower, which should have owners of the weightier Dodge Challenger Hellcat at least a bit nervous. All that power is complemented by 545 pound-feet of torque and what is almost certainly an ear-shattering exhaust note from the quad-tip pipes. On top of the RS3's trademark sound and speed, Roush has fitted the sixth-generation Mustang's body with a new "R7" aero kit that actually looks toned down from last year's car. 20-inch "Quicksilver" wheels are standard, although Roush is offering a pair of optional designs. Either way, Cooper RS3 tires are the rubber of choice. Prices for the Roush Stage 3 Mustang start at $21,995, not including the $32,300 starting price of a Mustang GT donor car.

The RS3 is cranking out a heart-racing 670 horsepower and 545 lb-ft of torque to deliver the ultimate driving experience. All 670 horsepower are created as a direct result of the powerful combination of Ford's 5.0L V8 engine with ROUSH Performance's dynamic new 2015 2.3L TVS supercharger. The new ROUSH Mustang's generous power ratings impeccably compliment the RS3's list of standard and optional features, including the ROUSH Quad-Tip exhaust (with optional ROUSH Active Exhaust System), standard single-adjustable coilover suspension system (or optional competition-tuned 3-way adjustable system), and the fierce new "R7" aerobody. The 2015 ROUSH Stage 3 Mustang is not just a car – it's an experience. The RS3 truly bridges the gap between road car and race car, putting drivers behind the wheel of the ultimate uninhibited muscle car.

Here are the best-selling cars and trucks from January 2015

Every month, Autoblog slogs through all the sales figures reported by automakers that do business in the United States, and, after a little bit of sorting, we put it into an easy-to-read chart in an attempt to make it as easy as possible to follow the ins and outs of sales and shipments. But that only covers the brands themselves, not the individual models they sell. And we think you'd all be interested in knowing which vehicles beat their rivals in sales from month to month, so we've put together this handy gallery to keep you in the know. While the leader of the pack may not come as much of a surprise, the order that the top ten finishes in changes frequently – due to automaker deals, the price of gas, etc. – and we've included some statistics to help you see how their current performance stacks up to month's past.
