Hennessey unleashes 2015 HPE700 supercharged Ford Mustang

Thanks to the 2015 Dodge Challenger SRT Hellcat there is a new magic number in the muscle car world - 707. To raise eyebrows these days in the power war, a vehicle needs to match or preferably exceed that palindromic figure. The tuners over at Hennessey took a look at it for their 2015 HPE700 Mustang and decided to go one better. Well, ten actually, because they bestowed their latest creation with 717 horsepower and 632 pound-feet of torque.
The HPE 700 Mustang takes the standard Mustang GT with its 5.0-liter V8 and turns up the power a few hundred notches with a Roots-type supercharger running at 7.25 psi. Hennessey claims that this boosted 'Stang can rocket to 60 miles per hour in about 3.6 seconds and cover the quarter-mile in 11.2 seconds at 131 mph. For those keeping score at home, those figures are very similar to Challenger Hellcat.
To cope with all of the added boost, the engine gets a high-flow throttle body, upgraded injectors, new fuel pump, stainless steel exhaust and Hennessey's calibration for the engine management. Pricing for the package is $59,500, including the base 2015 Mustang GT, but the company is limiting production to 500 units for the 2015 model year. Founder John Hennessey told Autoblog that he has already received about a dozen orders for them.

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.

Winnebago re-introduces classic Brave RV [w/video]

Winnebago is saying 'Let's do the time warp again,' using its new Brave RV to do it – have a look at the first Winnebago RV from 1966 and you'll know exactly where this one comes from. The modern version of this swinging sixties motorhome is accurate from its size, either 26- or 27-foot version, to its trademark eyebrow above the front windshield. The foldaway bunk above the front seats that necessitated the eyebrow design has been updated, and is now a power bed that descends from the ceiling. It is among a set of standard features that also includes a 19-foot motorized awning, leveling jacks at all four corners, heated mirrors, LED ceiling lights, two available floorplans and detailing like a workstation for the front passenger, a sliding dash cluster and and a waterfall countertop in the kitchen with built-in extensions. The Brave sits on a Ford F53 chassis complete with its Triton V10 engine and five-speed automatic transmission. No word yet on any potential diesel alternatives. Naturally, that 1966 price of $4,000 will also come in for an update, but the company hasn't yet revealed it. The good folks from Winnebago will be happy to take you on a thorough personal tour of the Brave in the video below. This content is hosted by a third party.
