Press Release
The ultimate Ford Mustang – Shelby GT500 – raises the bar high on
performance with the introduction of the new 2013 model that goes on
sale next year delivering 650 horsepower and a top speed of more than
200 mph.
“SVT keeps the Shelby GT500 on the cutting edge of technology and
takes muscle car performance to new heights,” said Jost Capito, director
of Global Performance Vehicles and Motorsport Business Development. “We
encapsulated every aspect of performance in this car – whether it’s
0-60, top speed, racetrack or quarter-mile times. Beyond that, the daily
driver also will find this car perfectly fits his or her needs.”
The 5.8-liter V8 aluminum-block engine produces 650 horsepower and
600 lb.-ft. of torque, making it the most powerful production V8 in the
world. The 3,850-pound car also stays exempt from the gas-guzzler tax.
Nearly every part of the powertrain has been optimized for producing
the additional horsepower, including a new supercharger, new
cross-drilled block and heads, updated camshaft profiles, a new carbon
fiber driveshaft and upgraded clutch, transmission and axle.
A larger, more-efficient supercharger flowing more air through the
engine is key to helping produce the massive 650 horsepower. The new TVS
series 2300 creates 2.3 liters of displacement and is a unique design
to the 5.8-liter engine.
The entire cooling system has been significantly updated on the new
5.8-liter engine. It now includes a larger cooling fan, fan shroud with
high-speed pressure-relief doors, a more efficient charge air cooler, a
higher-flow intercooler pump and an intercooler heat exchanger with
volume increased 36 percent.
Revised gearing
Nearly every gear on the 2013 Ford Shelby GT500 was revised to manage
the torque and use more of the power in a way that makes it more
driver-friendly. Engineers considered more than 35 gearing combinations,
finally deciding on one that delivers less torque all the way through
the wheels to the ground and still enables the car to achieve fuel
economy targets.
A key piece of the driveline, the six-speed manual transmission,
offers upgraded gears, bearings and housing so it can properly manage
the torque. The final drive ratio is now 3.31:1 for optimized overall
vehicle gearing to complement the massive torque. Every gear besides
fourth was optimized for competing performance metrics. The clutch has
increased torque and rpm capacity and uses a dual-disc design.
“It might just seem like we’re putting a bigger engine into the car.
But it’s been a balanced approach through and through,” said Jamal
Hameedi, SVT chief engineer. “We’ve completely redone the car to be even
more sophisticated in terms of handling and control than the prior
model.”
Other keys for improved traction management include:
- Torsen limited-slip differential:When customers order the optional Performance Package, they will get a Torsen limited-slip differential that helps the rear suspension deliver maximum torque and traction better and longer under track conditions
- Launch control: A new launch control system lets drivers set the desired launch rpm depending on tire temperature, street surface or other conditions. Unique to SVT’s launch control is that it is integrated with both the engine control and traction control
- Brembo braking system: A new Brembo brake system offers drivers enhanced stopping power to help keep their car under control, both on the road and the track. New six-piston calipers in front along with larger front and rear rotors help improve brake fade. New brake pads that are more aggressive also help the car achieve high deceleration and further robustness for more driver confidence
Aero advancements
Significant aerodynamic work was done on the new Shelby GT500 to
ensure the car has proper downforce for optimum performance at all
speeds. Engineers were able to determine how to harness the air that was
moving around and through the car to improve the cooling system,
maximize downforce and minimize drag.
The front fascia and splitters were modified to handle the extreme
loads at 200 mph, resulting in a car that tracks more securely and feels
more planted to the road at higher speeds. It offers 33 percent more
effective aero loading at 160 mph compared to the 2011 model.
Superior ride
The new Shelby GT500’s driving dynamics have been improved, now working in concert with all the new content on the car.
Handling, all AdvanceTrac settings and steering assist levels within
selectable steering have been tuned to account for the updated content.
The previously available unique traction control system and electronic
stability control settings help drivers achieve maximum performance on
both the street and the track.
Both systems can be completely disabled in controlled track
situations where maximum driver skill is utilized, or fully engaged for
maximum safety during normal driving or in less-than-ideal traction
conditions. Intermediate sport mode allows drivers to push their cars
hard at the track without completely disabling the safety systems,
permitting more aggressive driving before the traction control and
electronic stability control intervene.
“We took a completely different approach with this car so drivers can
choose their settings instead of a computer making the selection,”
Hameedi said. “Nearly every system the driver interacts with can be
tailored to his or her situation including the Bilstein electronic
adjustable suspension, launch control, AdvanceTrac and steering assist
levels.”
The 2013 Shelby GT500 offers two new sets of forged-aluminum wheels
including a unique wheel for cars with the optional packages. The
19-inch front and 20-inch rear wheels are coupled with Goodyear Eagle®
F1 SuperCar G: 2 tires on all vehicle configurations.
Taking it one step further
Sometimes Ford Shelby GT500 customers want to enjoy their car on
surface streets. Other times they just want to let loose on the track.
Two new optional packages on the 2013 model give them the choice.
Available as part of the optional Performance Package, SVT-designed
Bilstein electronic adjustable dampers are accessed on the dash with a
simple push of a button. Normal mode gives customers a more comfortable
ride over road irregularities. Sport mode is all about performance,
delivering improved response time on the track and less body roll while
cornering and pitch under braking. The Torsen limited-slip differential
also comes with the Performance Package.
“The adjustable shocks let us develop our car on the track without
any compromise,” said Kerry Baldori, Ford SVT Global Performance
Vehicles chief engineer. “Before, we had to tune the car with street
implications in mind. Now we can go as extreme as we want on the track
setting and still offer the customer a comfortable ride on the road.”
Enthusiasts can upgrade their Performance Package with an additional
Track Package for all-out performance. The option comes with an external
engine oil cooler, rear differential cooler and transmission cooler for
further durability. The coolers play an essential role in preventing
crucial components from overheating under high-speed conditions.
The 2013 Ford Shelby GT500 will be built at AutoAlliance International Plant in Flat Rock, Mich.
