CHICAGO %u2013 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%u2019s capabilities will be released later in 2011, as testing nears completion.
%u201CCamaro ZL1 is about high-tech performance and design, and is a type of car no one has ever brought to this segment previously,%u201D said Rick Scheidt, vice president of Chevrolet marketing. %u201CIt%u2019s the most technically advanced Camaro ever, so we%u2019ve chosen a name from the most elite and exclusive Camaro in history.%u201D
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%u2019ve achieved mythical status among enthusiasts, as they represented the pinnacle in Camaro performance %u2013 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%u2019s development was creating something new %u2013 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%u2019s systems, as well as incorporated new technologies such as electric power steering and Magnetic Ride Control, the world%u2019s fastest-reacting suspension system.
Camaro ZL1%u2019s 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%u2019s elevated capabilities.
%u201CEverything about the ZL1%u2019s design is directly related to its technology and serious performance, especially aerodynamics,%u201D said Ed Welburn, vice president, Global Design. %u201COur designers%u2019 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.%u201D
Major elements of the ZL1%u2019s design are a new front fascia and hood with air extractors, designed in tandem to create aerodynamic downforce to aid handling. The car%u2019s 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%u2019s handling and power.
The ZL1 badge appears on the grille, hood and the brake calipers, all key areas portraying the technology within.
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%u2019s 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%u2019s performance include:
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 %u2013 The high-performance Tremec TR-6060 six-speed manual is matched with the LSA engine. It is the %u201CMG9%u201D 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 %u2013 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 %u2013 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%u2019s tremendous power is delivered smoothly to the ground.
Suspension %u2013 The suspension features completely revised tuning and the inclusion of segment-exclusive Magnetic Ride Control. ZL1%u2019s 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%u2019s finest performance cars. Other chassis elements are redesigned to support the car%u2019s high-performance 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 %u2013 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 %u2013 ZL1%u2019s 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%u2019s high-performance intent as a visual contrast to the car%u2019s 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%u2019s aerodynamics.
Wheels and Tires %u2013 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 %u2013 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 %u201Cfour-pack%u201D auxiliary gauge system featuring a boost readout.
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.

2012 Chevrolet Camaro ZL1 - Click above for high-res image gallery
The 1969 Chevrolet Camaro ZL1 was a performance monster, featuring an all-aluminum engine displacing 427 cubic inches that was originally intended for racing. Just 69 units were built, and they are highly coveted by collectors today. Perhaps it shouldn't come as a surprise, then, that Chevrolet chose to resurrect this classic moniker for what it is calling the fastest and most technologically advanced Camaro ever built.
At this point, specifications are still preliminary, but Chevrolet is estimating that its supercharged and intercooled 6.2-liter LSA V8 engine will put out around 550 horsepower and 550 pound-feet of torque. Those ponies will be sent to the rear wheels via a six-speed manual transmission using a dual-disc clutch that's necessary to properly harness all those horses. There's also a dual-mode exhaust system that alters the sound level and character in response to engine rpm.
Chevrolet tells us that its goal was to built "a Camaro intended to reach optimal lap times on top road-racing circuits and excellent driving dynamics on the street." To that end, the 2012 Camaro ZL1 will be fitted with a new electric power steering system and Magnetic Ride Control that will offer both Tour and Sport modes. Brembo brakes measuring 14.6-inch (370 mm) in the front (with six-piston calipers) and 14.4-inch (365 mm) at the rear (with four-piston calipers) bring it all back down from speed.
Naturally, there's an updated body kit to differentiate the ZL1 from lesser machines. Most notable are the redesigned fascia that features a front splitter, vertical fog lamps and air intakes designed for brake cooling. There's also a new aluminum hood with a raised, satin black-finish carbon fiber insert that uses a unique air extractor that is said to increase downforce by directing oncoming air over the car. There's also a spoiler at the rear of the car and new 20-inch aluminum wheels fitted with specially developed Goodyear Supercar F2 tires.
Chevrolet promises to have the Camaro ZL1 on dealer lots in the beginning of 2012, and it will be available in any color offered on the Camaro. We can hardly wait. In the meantime, check out all the details in the video and press release after the break, and feel free to drool over the high-res image gallery below.
