Revealed at the Detroit auto show earlier this month, Ford's Shelby Mustang GT350R takes the all-new Ford Mustang, adds a 5.2 litre V8 engine with over 373kW, lightweight carbon-fibre wheels, a stripped out interior and race-spec suspension, brakes and aero gear.
According to a report by enthusiast website Horsepower Kings, the Shelby GT350R was been clocked around the Nurburgring Nordschliefe in just 7 minutes and 32.19 seconds back in September last year during testing (below).
That's a whole five seconds quicker than the Z/28, and a second faster than the Porsche. And who says muscle cars don't handle?
A great portion of that handling prowess is attributable to the GT350R's sophisticated suspension, brake and wheel package, which incorporates magnetorheologically adjustable dampers, carbon-ceramic brake rotors and super-lightweight carbon-fibre wheels.
The light wheels and brakes make a profound difference to performance.
The carbon wheels alone weigh 5.9kg less per corner than conventional alloy wheels, and the reduction in rotational inertia results in a car that accelerates, turns and stops faster.
All up the GT350R is said to be just under 59kg lighter than a standard GT350, with much of that reduction coming from the deletion of rear seats, air conditioning and the audio system.
It's important to note that Ford has yet to confirm this report, though with the car only having just made its first public appearance it's likely that Ford was saving that info for when the GT350R actually goes on sale.
The cat's out of the bag now, it seems.
