CHICAGO – The 2012 Chevrolet Camaro ZL1 debuted today at the Chicago Auto Show. It is
the highest-performing Camaro and the most technically advanced car ever developed in its
class. The new ZL1 continues the momentum of Camaro, propelling it into an entirely new realm
of leading-edge performance technology. It is planned to launch at the beginning of 2012.
Motivated by a supercharged V-8 engine producing an estimated 550 horsepower (410 kW), the
Camaro ZL1 will be the fastest Camaro ever offered by Chevrolet. And more than just power,
the ZL1 features technologically advanced and highly developed chassis and suspension
systems that help it deliver balanced, track-ready handling and braking power to complement its
high engine output. Rigorous development of the ZL1 is ongoing, and official estimates of the
car’s capabilities will be released later in 2011, as testing nears completion.
“Camaro ZL1 is about high-tech performance and design, and is a type of car no one has ever
brought to this segment previously,” said Rick Scheidt, vice president of Chevrolet marketing.
“It’s the most technically advanced Camaro ever, so we’ve chosen a name from the most elite
and exclusive Camaro in history.”
The ZL1 name is derived from the all-aluminum racing engine of the same name, which was
developed in the late 1960s and installed into a handful of regular-production 1969 Camaros.
Only 69 were built with the engine, but they’ve achieved mythical status among enthusiasts, as
they represented the pinnacle in Camaro performance – until now. The 2012 ZL1 model is
designed to be a major leap forward for the Camaro, bringing a new level of performance
capability to the segment.
The central goal of the car’s development was creating something new – a Camaro intended to
reach optimal lap times on top road-racing circuits and excellent driving dynamics on the street.
To achieve that goal, engineers evolved many of the existing Camaro’s systems, as well as
incorporated new technologies such as electric power steering and Magnetic Ride Control, the
world’s fastest-reacting suspension system.
Camaro ZL1’s design communicates and supports its performance mission. Rather than using
decorative elements, ZL1 is visually differentiated from other current Camaro models with
elements vital to the car’s elevated capabilities.
“Everything about the ZL1’s design is directly related to its technology and serious performance,
especially aerodynamics,” said Ed Welburn, vice president, Global Design. “Our designers’ goal
was to execute that function-oriented design with beautifully sculpted forms, creating an
imposing, powerful persona. Function becomes the aesthetic. The intent is a car that delivers on
the attitude it projects.”
Major elements of the ZL1’s design are a new front fascia and hood with air extractors,
designed in tandem to create aerodynamic downforce to aid handling. The car’s hood includes a
signature center section constructed of carbon fiber and rendered in satin black finish. New
rocker panels, wide tires, 20-inch wheels and exhaust tips portray the car’s handling and power.
The ZL1 badge appears on the grille, hood and the brake calipers, all key areas portraying the
technology within.
Tech overview
Supporting the dynamic track and street performance of the ZL1 is the LSA 6.2L supercharged
engine, which will produce an estimated 550 horsepower (410kW) and 550 lb.-ft. of torque (677
Nm), with specific features for the Camaro. Built on GM’s legendary all-aluminum, small-block
V-8 architecture, the LSA features an intercooled supercharger system, premium heat-resistant
aluminum-alloy cylinder heads and other details designed to ensure its exceptional performance
is delivered with smoothness and refinement. Components and design elements that contribute
to the LSA’s performance include:
�� Balanced, lightweight reciprocating assembly
�� High-strength hypereutectic pistons
�� Sixth-generation Eaton supercharger with four-lobe rotors
�� Piston oil squirters.
Because the Camaro ZL1 uses electric power steering, the engine does not incorporate a
conventional hydraulic power steering pump on its accessory drive system. This enhances
performance, because no engine power is used to turn a steering pump pulley.
Camaro ZL1 is a complete high-performance car, not just a Camaro with more power. Key
technical highlights include:
Transmission – The high-performance Tremec TR-6060 six-speed manual is matched with the
LSA engine. It is the “MG9” version of the transmission, with a higher torque capacity. It is used
with a dual-mass flywheel and twin-disc clutch for easy operation and shift smoothness. A new,
shorter-throw shifter actuates the gear changes.
Exhaust – ZL1 is equipped with a dual-mode exhaust system, which alters the sound level and
character in response to engine rpm. First used on the legendary Corvette, and specifically
tuned for Camaro ZL1, the dual-mode exhaust will give the car a signature sound.
Drivetrain – It is revised with a stronger driveshaft and rear axle system, featuring a larger and
stronger cast iron differential housing, stronger axles and heavy-duty limited-slip differential.
This patent-pending system is designed to ensure that ZL1’s tremendous power is delivered
smoothly to the ground.
Suspension – The suspension features completely revised tuning and the inclusion of
segment-exclusive Magnetic Ride Control. ZL1’s Magnetic Ride system will include driver
selectable modes (Tour and Sport) tailored for the preferred style of driving. It uses advanced
magneto-rheological science to produce shock damping with the highest level of precision,
enabling body control optimized for excellent performance in everyday driving as well as track
situations. This technology appears on only a small roster of some of the world’s finest
performance cars. Other chassis elements are redesigned to support the car’s highperformance
limits. Rear stabilizer bars have drop links repositioned outboard of the control
arms. This makes the bars more effective in controlling body roll in turns, with crisp response to
driver commands.
Brakes and Steering – Camaro ZL1 features an advanced track-capable braking system,
developed in conjunction with experts from Brembo. The large 14.6-inch (370 mm) two-piece
front rotors have six-piston calipers; the 14.4-inch (365 mm) rear rotors have four-piston
calipers. ZL1 marks the entry of a new electric power steering system to Camaro. It is being
developed to ensure precise control and feedback to the driver, with greater variability of effort
for high-performance driving.
Exterior – ZL1’s signature from the front is the redesigned fascia and aluminum hood with a
raised, carbon fiber insert. The fascia includes a front splitter and new vertical fog lamps. The
fog lamp area includes air intakes designed for brake cooling. The hood features front-mounted
air extractors that direct air precisely over the car. Visually, this center section, in satin black
carbon fiber, communicates the car’s high-performance intent as a visual contrast to the car’s
exterior color. Functionally, the air extractor is a key in connecting airflow closely to the
bodywork, creating aerodynamic downforce. The carbon fiber center section reduces the mass
of the hood. High-intensity discharge (HID) headlamps and fog lamps are standard. The rear of
the car includes a diffuser and spoiler, also functional elements that enhance the car’s
aerodynamics.
Wheels and Tires – New-design, 20-inch forged aluminum wheels, which are lighter than the
20-inch wheels used on the Camaro SS, are used with new Goodyear Supercar F2 ties
developed specifically for the ZL1.
Interior – ZL1 is tailored for high-performance driving. The front seats feature microfiber suede
inserts. Other enhancements include a redesigned steering wheel, alloy pedals, Head-Up
Display with unique performance readouts and the “four-pack” auxiliary gauge system featuring
a boost readout.
Production details
All of the Camaro exterior colors will be offered with the ZL1, but black is the only interior color.
The unique exterior features are complemented with a black center section on the hood. Inside,
the Camaro ZL1 has heated leather seats with microfiber inserts and ZL1 logos embroidered on
the front headrests. Microfiber suede is repeated as an accent on the instrument panel, adding
a richer look to the interior. The ZL1 will include the same content as the current 2SS package
and include the following new or unique features:
�� Six-way power driver and passenger seats
�� Unique instrument panel and door panel inserts; and ZL1-logo sill plates
�� Steering wheel audio controls with Bluetooth capability
�� Wireless PDIM and USB-port
�� Boston Acoustics premium audio system
�� Rear parking assist
�� Rear camera system (displayed in the inside rearview mirror).
Engineers have already driven Camaro ZL1 prototypes extensively at demanding road courses
in the U.S. and Germany, with final testing being completed through the balance of 2011.

2013 Ford Shelby GT500 Debuts as Most Powerful Production V8 in the World with 650 Horsepower, Top Speed of 200+ MPH

• New Ford Shelby GT500 is powered by an aluminum 5.8-liter supercharged V8 producing 650 horsepower and 600 lb.-ft. of torque, making it the most powerful production V8 engine in the world

• Nearly every vehicle system has been optimized including powertrain, brakes, gearing and suspension

• New Shelby GT500 sets a performance-driven design standard with new downforce- generating front grilles, aggressive splitter, new quad exhaust system and two new forged-aluminum wheels

• Also new for 2013 is an optional Performance Package with SVT-designed Bilstein electronic adjustable dampers and a Torsen limited-slip differential. The offering can be coupled with a Track Package for all-out racetrack performance

LOS ANGELES, Nov. 15, 2011 – 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.
