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.

Next SVT Mustang may axe Shelby name, go naturally aspirated

Following our first glimpse at the 2015 Ford Mustang out on the road, the fine folks at Road and Track have divulged some details on what the Blue Oval's next pony might have in store. We've already seen that the car will get some very sleek, Evos-inspired design cues, and an independent rear suspension is indeed in store. These new details, however, concern the muscle car's beating heart.
For starters, the base Ford coupe is expected to carry on with V6 power, likely from the same 3.7-liter unit found in today's car. From there, R&T says the next step up will be a four-cylinder EcoBoost engine, likely displacing 2.3 liters, putting out as much as 350 horsepower. Of course, a Mustang wouldn't be a Mustang without V8 thrust, and R&T states that the 5.0-liter Coyote V8 will continue on into the 2015 car, making something like 450 horsepower.
But it's at the high end of the Mustang range where things will, reportedly, get very, very interesting. Road & Track claims that the top-shelf 'Stang will likely lose the supercharger from its engine, producing a metric crap-ton of naturally aspirated grunt instead. Additionally, the SVT-fettled Mustang will likely be dropping its Shelby moniker, in favor of "a name you're familiar with," according to the magazine (you know, like, Cobra).

Galpin-Fisker Rocket shows up topless in Monterey

The Rocket Coupe, introduced at the Los Angeles Auto Show last year, was a collaboration in reimagination carried out by designer Henrik Fisker and Galpin Auto Sports on a Ford Mustang. The next version of that concept has come to Pebble Beach in the metallic red form of the Rocket Speedster Concept you see here. In this guise the Mustang convertible gets a speedster tonneau cover that runs all the way to the front seat headrests, covering the back seats. As with the rest of the bodywork the cover is fashioned in carbon fiber, portions of it visible in places like the stripes running along the hood from the hexagonal grill to the tonneau, and the exposed carbon fiber air ducts that are mesh-filled to improve airflow through the cabin. And yes, it still has that nose. Underhood is a supercharged 5.0-liter V8 with 725 horsepower, all that cavalry brought to a stop by 15-inch Brembo Gran Turismo brakes up front tucked behind 21-inch custom wheels. Although it is labeled a concept, it too will go into limited production like its hardtop forebear. The press release below has the info, the gallery above has the goods.

(August 15, 2015) – Galpin Auto Sports and Henrik Fisker unveiled the latest iteration of the "Ultimate American Muscle Car" today at the 2015 Pebble Beach Concours d'Elegance; the 2015 Rocket Speedster Concept. Following a short drive onto the legendary Pebble Beach Concept Lawn, Henrik Fisker and Galpin Motors President, Beau Boeckmann introduced the convertible carbon fiber-bodied super-Mustang, intended for low-volume production. The car was featured as one of only a few special designer cars in front the Lodge at Pebble Beach. Featuring a fully integrated carbon fiber speedster cover that transforms the four-seat convertible into a two-seat speedster, this new edition Rocket maintains exceptional visual drama and performance with the top up or down. As with the Rocket Coupe, the Concept carries a carbon fiber hood feeding air into the supercharged 725-hp V8 engine through two sculpted air intakes, aiding the grill and front splitter in maintaining optimal cooling and aerodynamics.
