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.

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.

Radical RXC is a Mustang-hearted racecar for the road

Radical has been building fantastic open-cockpit racers and roadcars for years, for the track day enthusiast who wants a vehicle that looks like it could show up for a start at the 24 Hours of Le Mans. The company's latest creation is the RXC, and while this coupe looks like a prototype racer, it's road legal in the UK and in some parts of the US. When testing a car this, um, radical, the first thought is likely to get it to the track for some big slides and wide open acceleration, but XCar Films takes the opposite approach in its latest video to learn how this racer fares on public roads. The version tested here is the standard RXC with the 3.7-liter V6 out of the Ford Mustang tuned to 350 horsepower with a seven-speed sequential gearbox; but Radical also offers the same engine with 380-hp, a 454-hp Ford EcoBoost 3.5-liter twin-turbo V6, or even a 500-hp V8. Even in the most basic guise, it's a handful to control in the wet, if this video is any indication. The cliche of a road-legal racecar is bandied around a lot in the motoring world, but it truly applies to the RXC. The only problem with seeing the RXC exclusively on the road is that it can never really open up and show its full potential. This racer is indeed chomping at the bit to rocket off into the horizon, but all those pesky road safety laws hold it back. Still, the video is a chance to get a better impression about this thoroughbred sports car. Scroll down to check it out. This content is hosted by a third party.
