DEARBORN, Mich., Feb. 8, 2010 – Ford's Special Vehicle Team (SVT) engineers are taking high performance to a new level with the 2011 Ford Shelby GT500, resulting in a car that has an all-new aluminum-block engine, even better driving dynamics and handling, improved fuel economy and more horsepower than ever.




Weight savings, new technology headline all-new aluminum engine
The 2011 Shelby GT500 is powered by an all-new aluminum-block 5.4-liter supercharged V-8 engine, which produces 550 horsepower and 510 ft.-lb. of torque, a 10 horsepower increase versus the 2010 model. The engine also is 102 pounds lighter than its predecessor, delivering a better power-to-weight ratio, improved fuel economy, acceleration, handling and steering precision.

'Cutting weight to improve performance is a tradition among hot rodders,' said Carroll Shelby, founder of Shelby American. 'It might not be as sexy as adding more horsepower or bigger brakes, but shaving pounds off of a car is the single smartest move you can make.'



This is the first Ford application of the technology, and it offers improved overall performance and durability, along with functional benefits of reduced friction between piston rings and cylinder bores, improved heat transfer due to increased surface contact area and a weight savings of 8.5 pounds compared to a typical steel-sleeved aluminum block. A mechanical roughening process provides higher material adhesion for the spray coating.

The PTWA process uses air and electricity to create a plasma jet of 35,000 degrees Fahrenheit, which melts a steel wire that is fed into a rotating spray gun. Úsing atomized air, the melted steel wire is blown into a specially machined surface of the aluminum-block engine cylinder bore. In the process of melting and applying the metal to the surface, the steel wire oxidizes, creating a composite coating consisting of both iron and iron oxide.

'Ford's Global Research and Advanced Engineering looks to all industries for advanced technologies – and this comes from aerospace. It's the same technology you would find on aircraft engines,' said Glenn Jorgensen, SVT powertrain team leader. 'We've invented a coating as a replacement for cast iron that delivers improvements in power and performance and fuel economy.'

The new engine also has its roots in the iconic Ford GT. The new 5.4-liter engine is an evolution of the GT engine, with improved block structure through the use of a unique bulkhead chilled process and six-bolt billet main bearing caps. This new advanced engine will exceed Ford GT performance with its traditional supercharger technology.

'The Ford GT has solidified itself as one of the world's most coveted supercars. To make improvements to the engine from this supercar and make it available in a Mustang is impressive,' said Kerry Baldori, SVT global performance vehicle chief functional engineer. 'The aluminum-block engine is robust and strong enough to produce the performance numbers and durability our customers demand.'

Increased power and increased fuel economy
The 2011 Shelby GT500 combines power and fuel economy into one impressive package. This 2011 Shelby GT500 will be the first modern Shelby without the gas guzzler tax, thanks to the EPA-projected 23 mpg highway and 15 mpg city it will deliver. This is up from 22 mpg highway and 14 mpg city for the 2010 model.

The 5.4-liter V-8 achieves 80 percent of its torque between 1,750 and 6,250 rpm, giving the car a higher level of performance feel. A larger two-row intercooler for the supercharger system has 40 percent more cooling capacity, helping to make power more consistent in higher ambient conditions.

Fuel economy gains come from the new 102-pound-lighter aluminum-block engine, EPAS and detailed aerodynamic changes to the underside of the vehicle.

Dramatic performance upgrades
New for 2011 is an SVT Performance Package for enthusiasts who want even more performance out of their Shelby GT500 for racetrack-ready driving dynamics. Complete with all-new Goodyear Eagle® F1 SuperCar G: 2 tires that SVT engineers worked directly with Goodyear to develop, the car is ready to race. The tires offer superb dry traction and precise handling, complete with a race-inspired high-performance tread compound.

The optional package also offers unique styling, lighter wheels, a higher rear axle ratio and stiffer springs, and it is available on both the convertible and coupe. Data show the 2011 coupe with the SVT Performance Package is 3.0 seconds faster per lap than the 2010 Shelby GT500 on a 2.3-mile test track.

Carried over from 2010, the 2011 Shelby GT500 features AdvanceTrac®, Ford's stability control system with several options for performance. Calibration of the system for the 2011 Shelby has been uniquely tailored to each vehicle configuration (base or optional) to optimize the performance.

SVT has worked very hard to make EPAS better than the outgoing hydraulic steering system. The addition of EPAS makes for a dramatic contribution to Shelby GT500 driving dynamics, with improved torque build-up and road feel that delivers quicker and more precise steering, increased effort on the racetrack or winding roads, and reduced effort in low-speed parking maneuvers.

Slotted brake dust shields were added to improve brake cooling and handling, and a new pedal box improves clutch and pedal efforts even more. A lowered ride height of 11 millimeters in front and 8 millimeters at the rear provides a sportier attitude and improved handling.

More engine sound, less road noise
For 2011, Shelby GT500 also benefits from NVH (noise, vibration and harshness) improvements. Overall road noise is reduced by 20 percent versus the 2010 Shelby. Actions undertaken to achieve this improvement include additional sound-deadening material on either side of the instrument panel, additional sound absorption behind interior trim panels, and a rear wheel arch liner to reduce noise on gravel or wet surfaces – all resulting in the driver hearing more exhaust and engine sound and less road and air noise.

The Shelby GT500 convertible model features enhanced structural rigidity, with lateral stiffness improved by 12 percent versus the 2010 model. The V-brace has been stiffened by adding gussets. The secondary crossmember also has been stiffened, while a front Z-brace has been added, connecting primary and secondary crossmembers. A-pillar stiffening foam has been added to increase rigidity.

The structural improvements to the convertible gave SVT the opportunity to be more sport-oriented in the chassis tuning, without trading comfort. Along with the chassis and structural improvements, the 2011 model also will get standard 19-inch aluminum wheels.

'One of the biggest changes for this Shelby is that the convertible acts and feels like a coupe,' said Jamal Hameedi, SVT chief nameplate engineer. 'Before, they had a very different character, and the convertible is taking a big step in the sportiness and handling precision area, without degrading the ride.'

GT500 gets a new exhaust for 2011, roaring with an even more aggressive sound than the 2010 model. The 2.75-inch exhaust with all-new tuning helped to deliver the additional 10 horsepower.

Added convenience content
New for 2011 is an optional glass roof, providing customers with a less expensive option than a convertible and without compromising the coupe's versatility, headroom or climate-controlled environment.

The specially formulated glass also protects interior fabric material from solar radiation deterioration and discoloration by reducing solar light transmittance. To help improve acoustics and interior quietness, the glass features a layer of vinyl that reduces noise, vibration and harshness.

Other new convenience technologies include:

* Standard HID (high-intensity discharge) headlamps
* MyKey™ programmable vehicle key
* Integrated spotter mirror
* Fold-down rear headrests

'Whether you're looking to take the GT500 out on the streets or have some fun at the track,' Capito says, 'this car will satisfy the most discriminating performance driving enthusiasts.'

NEW SVT PERFORMANCE PACKAGE READIES 2011 FORD SHELBY GT500 FOR THE TRACK

DEARBORN, Mich., Feb. 8, 2010 – The new 2011 Ford Shelby GT500 has a surprise in store for true performance enthusiasts – an optional SVT Performance Package. One lap around the racetrack, and drivers will feel the difference.
Data show the 2011 coupe with the SVT Performance Package is 3.0 seconds faster per lap than the 2010 Shelby GT500 on a 2.3-mile test track. Cars with the optional package will be able to pull 1.0 lateral g, with stopping distances improved by 7 percent versus the base 2011 Shelby.




Tires make the difference
The SVT Performance Package features the first application of the all-new Goodyear Eagle F1 SuperCar G: 2, a tire that offers superb dry traction and precise handling, complete with a high-performance tread compound with more grip. SVT engineers worked directly with Goodyear to develop the new compound, and it's only available on the 2011 Shelby GT500. The tire is unidirectional, corner-specific – meaning the directional tread must match its specific location.

'We wanted to couple the improved weight distribution and the improved handling of the vehicle with the new tire, and with that offer the customer one of the most advanced summer tires from a manufacturer,' said Jamal Hameedi, SVT chief nameplate engineer. 'That led us down a road to the new tire. It's instantly recognizable with an all-new tread pattern and construction.'



'These tires are as close as you can get to a race car tire,' said Eric Zinkosky, SVT technical specialist. 'We have a tire that's way more capable, with better grip, is firmer and more race-oriented. From there, we tuned the chassis around it. The tires told us what we had to do.

'We took some lessons from the Shelby KR program and applied them to these tires,' he added. 'That was our first attempt at a similar compound, and we learned a lot and rolled those lessons into the new Shelby to provide an even better tire.'

Nineteen-inch forged-aluminum wheels in the front, which are 4.7 pounds lighter than the base Shelby GT500's, complement the all-new wider 265/40R-19 front tires. New 20-inch forged-aluminum wheels at the rear are 2.8 pounds lighter than the standard 19-inch wheel, and the new 3.73 rear axle ratio takes advantage of the new larger rear wheels and tires.

Little things add up
As a result of the increased tire performance, the chassis was tuned to respond more like a race car. The front and rear shocks were also tuned, adding control to work better with the chassis and tire. The front springs are 20.5 percent stiffer than the base, and the rear springs are 9.5 percent stiffer, continuing an SVT performance tuning direction of adding more stiffness in the front and keeping the rear softer to aid acceleration traction. Roll stiffness also helps control cornering while on the track.

A lowered ride height of 11 millimeters in front and 8 millimeters at the rear improves handling and gives the car an even sportier attitude. High-temperature dry shaft center bearing bushing and shifter bushings – which are also on the base Shelby – ensure that no matter how hot the conditions get, the car will still perform at its best.

'This car is track-ready. We really took the Shelby GT500 to the next level and went through every detail,' said Kerry Baldori, SVT global performance vehicle chief functional engineer. 'It offers great cornering and racetrack performance and proven durability, and that's something we want our customers to appreciate.'

A unique rear spoiler Gurney Flap was developed for increased rear downforce and improves handling balance in high-speed corners. Introduced by racing legend Dan Gurney nearly 40 years ago, the flap is essentially a tunable element on a low-drag spoiler. Front downforce has been increased 25 percent through improved cooling pack sealing and a new front underbody closeout panel. Grippy bushing stabilizer bars provide improved roll stiffness.

Even with the stiffer springs, lower ride heights and increased damping, the ride remains very compliant, and the car can be easily driven on everyday roads due to SVT's chassis tuning philosophy.

Design cues are added to set the package apart from the base Shelby GT500. The over-the-top stripes are narrower, and the stripes on the shift knob were removed. The performance shocks also are painted red to further differentiate the package. 'This car has great handling and dramatically improved performance, and that should come out in better lap times and improved braking,' said Zinkosky.
