Rare Ford Mustang ASC McLaren is a piece of '80s history

You can't blame the dealer for advertising this oddball convertible as a "Ford Mustang McLaren." The name certainly rolls off the tongue better than "Ford Mustang ASC McLaren," and it makes the car sound a whole lot more appealing. However, without the 'ASC' in there, you don't get the full picture. And when it comes to the world of strange automotive collaborations—particularly those of the 80s—you most definitely want the full picture. ASC McLaren Mustangs were the result of fortuitous timing, and a project that was already underway between the American Sunroof Company and McLaren (no, not that McLaren). Detroit custom car builder Peter Muscat brought the idea of a Mustang with a tonneau cover to ASC after chopping the top off a Fox body on his own, and in turn ASC founder Heinz Pretcher brought the concept to Ford. Big blue was already in the midst of relaunching a Mustang convertible, which had been absent from the lineup for 10 years, so initially it was the Mercury Capri that got the ASC/McLaren treatment. The result was a car that was more expensive than a Mustang GT, and coupled with declining sales of the Capri overall, the car was discontinued in 1986, paving the way for the ASC McLaren Mustang you see here on eBay. With the change over to the Mustang as their platform for modification in 1987, ASC McLaren were given the opportunity to create something notable. Customizing the Capri was one thing, but the Mustang name carries with it iconic status. So what did ASC McLaren do with their chance to leave their mark on automotive history? They gave the car some visual modifications, both inside and out, but like the Capri, left the powertrain untouched. Also like the Capri, the cars still ended up costing more than $20,000. Between the high price, the economic woes of the late 80s, and disputes between Muscat and Pretcher, the ASC McLaren Mustangs were no more by 1990. During the three year run, 1,806 ASC McLaren conversions were completed, making them quite rare, especially low mileage examples like this one. The 5.0 V8s are known for being stout engines, capable of handling serious modification, and logging lots of miles, so there are no concerns there. The 5-speed Borg-Warner transmission that came in all Mustang GTs is also known for being a durable unit, the '87-'90 versions especially so. The main concern here would be the life the car has lived, and more importantly where it has lived.

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.

Are you a new Ford Mustang SVO? [w/video]

When Ford announced that its 2015 Mustang would arrive with a 2.3-liter EcoBoost four-cylinder engine, three letters came to mind: SVO. While Ford hasn't said a word regarding the rebirth of a Mustang SVO model, this latest set of spy shots shows us something very, very interesting. Allow us to explain.
The Mustang prototype in these photos looks very similar to the GT500 test cars we've spotted before - same bulging hood, aggressive front fascia and air vents aft of the front wheels. What's different, however, is around back. Have a look at the exhaust, and note that instead of the GT500's usual quad pipes, two of the exhaust outlets have been capped off.
Our spies point out that these exhaust outlets could be closed for some sort of emissions testing or another engineering reason, but it's also important to note that the engine and exhaust notes of this car sound completely different from earlier GT500 prototypes. We've got a video below that compares the two.
