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.

2016 Ford Focus RS may yet be AWD, US sales likely

When it comes to forbidden fruit, few vehicles are spoken of in as hushed a tone as the Ford Focus RS. The turbocharged, five-cylinder hot hatch could only be seen from afar by American customers as it tore up the roads of Europe. And while it's safe to say that Ford's Yankee fans are quite happy to now be on equal footing with drivers in the old country thanks to the Focus ST, we doubt there'd be much protestation over a successor to the RS arriving stateside.
Of course, we've seen images of the new RS undergoing testing, but a new story by Road and Track aims to fill in some very large blanks in our knowledge of that car, thanks to a pair of mysterious insiders at the Ford. Chief among those is this - the RS will almost certainly make its way to the US, albeit in limited quantities. It gets better, though.
Under hood, the new RS is unsurprisingly expected to borrow the 2.3-liter, turbocharged four-cylinder from the 2015 Ford Mustang and 2015 Lincoln MKC. While that twin-scroll turbo produces 310 horsepower in the Mustang and 285 ponies in the MKC, R&T expects the RS to deliver quite a bit more firepower - 325 to 350 hp, with preference going to the higher output due to the limited-edition nature of the RS. This roughly fits with previous reports.

Project Ugly Horse: Part VI

Solid axle? What solid axle?
I was fully prepared to embark on a seven-day journey down a rabbit hole of broken bolts, internet hearsay and consternation.
This should not have gone this easily. Having a long and checkered history of simple projects punctuated by much wailing and gnashing of knuckles, I was fully prepared to embark on a seven-day journey down a rabbit hole of broken bolts, internet hearsay and consternation when I finally decided to lay hands on the '89 Mustang with the goal of relieving the car of its stock rear axle. Instead, it took less than a full morning's worth of work to carve the old 7.5-inch solid axle from its moorings and mock up something, well, different.
