Shelby GT500 laps N"urburgring in under 7:40?

A couple of weeks ago we brought you footage and official times of the new Chevy Camaro Z/28 lapping the Nürburgring. With a 7:37.47 lap time, the Z/28 emerged as the fastest muscle car ever to lap the circuit. But what was missing from that picture was how fast the king of all Mustangs, the Shelby GT500, could manage to lap the Nordschleife.
Ford never released any information or footage of the GT500 on the Nürburgring that we were aware of - that is, until the guys at SVTPerformance.com put in a request for Mustang videos. Among the clips they received was never-seen, in-car footage of the Shelby GT500 lapping the circuit. And boy did it hustle.
Although not quite official, the video seems to show the GT500 lapped the venerated German track in a touch under 7:40. That would make it a tick or two faster than the Camaro ZL1 - but what of the Z/28? By Chevy's quoted time, the Z/28 is still faster than the GT500, but SVTPerformance suggests GM may have fudged the numbers a bit and scrubbed half a second or so off their lap time.

Ford, Petty's Garage to build limited-edition Mustang GT from SEMA Show

The customized vehicles on display at the annual SEMA Show are often just there to exhibit a company's wares. They are more an illustration of what's possible by picking the right bits out of a catalog, rather than a model available in complete form. Ford and Petty's Garage are doing something a little different, though, by putting a very limited run of the tuner's supercharged Mustang GTs up for order through Blue Oval dealers. The Petty's Garage Mustang GT made its debut with a host of other modded 'Stangs at the 2014 SEMA Show. It featured a blue-and-black two-tone paint job and a supercharged version of the pony car's V8 under the hood. Just 143 of them are now being offered to customers – 100 in Stage 1 trim and 43 in Stage 2 form. At a starting price of $62,210, Stage 1 buyers get the aggressive body kit from the show car, including a center-exit exhaust at the rear, trunk lip spoiler and a set of 20-inch wheels. Although the real meat of the setup is a supercharger, cold air intake and retuned engine calibration also help take the output up to 627 horsepower. Inside, customers get "The King" Richard Petty's signature on the dashboard. Shelling out $92,210 for the Stage 2 version adds bigger brakes from Wilwood, HRE three-piece wheels and the two-tone paint job from the SEMA show car. The boosted Mustangs can be ordered from Ford dealers, but at least one of the Stage 2 versions is already sold. Rocker and car enthusiast Brian Johnson of AC/DC bought the first one.

"We received a tremendous amount of positive feedback about our Petty's Garage Mustang GT displayed at the SEMA show," said Jeff Whaley, Petty's Garage COO.

2015 Ford Mustang EcoBoost loses big power on 87 octane

The 2015 Ford Mustang with the 2.3-liter EcoBoost four-cylinder is a pretty potent package on paper. With 310 horsepower and 320 pound-feet of torque, it boasts better performance numbers than the 3.7-liter V6, but with better fuel economy as an added benefit. However, if you're in the market for one of these boosted 'Stangs, you should probably keep in mind that it really prefers to gulp premium, 93-octane fuel. It can drink 87-octane swill in a pinch, but you're going to find significantly less power underfoot when pulling away. While it's not shocking that the ponies are dialed back with a lower grade of gasoline, an alleged page from a Ford training manual obtained by Mustang 6G purports to show just how much power is lost, though. According to this document, the 2.3-liter EcoBoost makes 275 horsepower and 300 pound-feet of torque when running on lower octane fuel. That's a substantial reduction of about 11.3 percent compared to when the engine drinks 93 octane. Interestingly, according to Mustang 6G, that finding was a bit better than expected, because a Ford engineer reportedly said power would be down about 13 percent without altering peak torque. In speaking with Autoblog, Paul Seredynski of Ford powertrain communications, objected to part of this document. While he couldn't confirm the specific losses listed for the Mustang EcoBoost, "torque remains unchanged" with lower octane gasoline, Seredynski said. He speculated this training manual page was "possibly from before the engine was certified" and therefore showed incorrect figures. Serendynski did confirm that the automaker recommends using 93 octane, and like all modern engines, the software adapts if it's lower. "Peak power would be reduced" by using a lesser grade, he confirmed.
