Ford F-150 EcoBoost in NHTSA probe for acceleration issue

According to Automotive News, the National Highway Traffic Safety Administration is launching a probe into 400,000 Ford F-150 models over possible acceleration problems. According to the article, NHTSA has received 95 reports "alleging incidents of reduced engine power during hard accelerations" on 2011 to 2013 F-150 models equipped with the company's 3.5-liter EcoBoost V6 engine.
Automotive News reports that Ford has issued three technical service bulletins "related to intermittent stumble/misfire on acceleration from highway cruise in humid or damp conditions," according to the government agency's documents. About one third of the 95 reports NHTSA has received cited humid or rainy conditions when these problems allegedly occurred.
These technical service bulletins have allowed dealers to address a "condition related to moisture accumulation in the charge air cooler during extended highway cruising at constant throttle in humid or damp conditions," AN reports, citing NHTSA documents. Furthermore, the TSB outlines details for "reprogramming the powertrain control module with the latest calibration and installing a new CAC and air deflector plate."

2015 Hennessey Ford Mustang hits 207.9 mph

After hitting over 195 miles per hour a few months ago, John Hennessey was barely out of his personal HPE700 Mustang before he said that 200 mph was achievable. Don't doubt a man who knows a ton about taking cars to insane speeds. With the new HPE750 Mustang, he and his customers can finally surpass the 200-mph mark in their cars. "If at first you don't succeed, just add more horsepower and rpm and try again," Hennessey said in the company's announcement. Rather than the 717 horsepower and 632 pound-feet of torque from the supercharged 5.0-liter V8 in the HPE700, the HPE750 ratchets the same powertrain up to an even more potent 774 hp and 648 lb-ft. In a real show of confidence, the Hennessey team brought along Jay Leno when it returned to the Continental Tire Proving Grounds in Uvalde, TX, to set a new top speed with the HPE750. The upgrades to the Mustang definitely paid off because the pony car reached a GPS-verified 207.9 miles per hour down the straight. The run will eventually appear on a segment on the upcoming Jay Leno's Garage TV show that will air CNBC. Prices for the HPE750 start at $59,500 USD, including the base 2015 Mustang GT, but building an exact replica of this one would cost $69,374, according to Hennessey. In addition to the huge top speed, the company claims that the coupe can reach 60 mph in 3.4 seconds and cover the quarter mile in 10.9 seconds. 774 HP Hennessey Mustang Tested to 207.9 mph Jay Leno visits Texas tuner for upcoming TV series on CNBC June 2, 2015 Uvalde, Texas—On Wednesday, May 27, 2015, professional driver, Brian Smith, drove the Hennessey HPE750 Supercharged Mustang to a top speed of 207.9 mph. In the process, Hennessey's potent pony car became the first 2015 Mustang to break the 200 mph mark. Jay Leno was on hand to witness the record speed while filming an upcoming episode of Jay Leno's Garage, which will air on CNBC later this year. The run was made on the 8.5 mile high speed oval at the Continental Tire Proving Grounds located in Uvalde, Texas – the same test track where John Hennessey test drove the company's HPE700 Mustang to a top speed of 195 mph back in February of this year. During both tests, speeds were validated with Racelogic's VBox 3i GPS data logging system. "If at first you don't succeed, just add more horsepower and rpm and try again," said company founder and president, John Hennessey.

Galpin Auto Sports and Fisker turn the Mustang into a Rocket in LA [w/video]

Galpin Auto Sport and Henrik Fisker made big promises about the Rocket before its debut at the Los Angeles Auto Show today, calling it the "ultimate American muscle car." Now that this 725-horsepower carbon-fiber Ford Mustang has officially been revealed, we've now got a chance to see if their vision backs up all the bluster. The Rocket is based off the latest 2015 Mustang, but the entire exterior design has been substantially reworked by Fisker. "This is a project born out of passion, it's a dream come true, to have the opportunity to 'touch' a Mustang and apply my design ideas to it," he says in the model's announcement. The biggest changes come up front, where Fisker has added a gaping hexagonal grille with a polished bar running and two nearly hidden driving lights at the top corners. Long nostrils run down each side of the hood, taking their inspiration from the 1968 Shelby GT500. The Rocket's design also emphasizes its scalloped sides, which run back to functional ducts at the rear to cool the Brembo Grand Turismo brakes. When checking out the Rocket from the rear, it's easy to spot the wider fenders that are beautifully blended into the integrated spoiler. The interior has been left mostly alone beyond some eye-grabbing red leather and carbon-fiber trim. Under the hood, Galpin spokesperson Nathan Hoyt has confirmed to Autoblog that the Rocket employs a 5.0-liter V8 with a Whipple supercharger which can be called to attention with a six-speed manual gearbox. It took only a few months for the vehicle to go from conception to reality. Fisker showed Galpin President Beau Boeckmann early sketches at this year's Pebble Beach Concours d'Elegance, and the two parties went from there. "When Henrik showed me his ideas, I got chills - it's literally the most beautiful Mustang I have ever seen," says Boeckmann in the company's release. Production is set to begin in December, with deliveries starting in early 2015. There's no set production total in mind for now, but Hoyt tells Autoblog that the price will be "just over $100,000."
