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.

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 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 – 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.
