After months of speculation, the new uber-Camaro was revealed today at the Chicago Auto Show. To the surprise of many, the car didn’t carry the expected Z/28 nameplate; instead, Chevy opted to label the car the Camaro ZL1. Don’t feel bad if you don’t know the significance of that name, since it was used only once, as an internal order code for an aluminum-block racing engine option on the 1969 Camaro. Only 69 were ever built with the ZL1 order code, and their performance and value is the stuff of legend. What better way to honor the name than by building the most powerful and most capable Camaro in Chevrolet’s history?

As rumored, the ZL1 gets powered by the LSA, 6.2 liter supercharged V8 from the Cadillac CTS-V. The ZL1 loses a few ponies in the translation, since the CTS-V is a Cadillac and the Camaro is a Chevy. If you want specifics, the ZL1 gets rated at 550 horsepower versus the Caddy’s 556, while torque drops to 550 ft lb from the CTS-V’s 551. It’s academic, really, and I suspect that both cars would put out nearly identical numbers on a dyno. I wouldn’t be a bit surprised to find that the ZL1 has a similar zero to sixty time (3.9 seconds for the Caddy), but Chevy isn’t publishing those numbers just yet.

Unlike Camaros of old, the ZL1 is designed to excel at racetracks other than drag strips. The engineers raided the GM performance parts bin, and pulled the good stuff for use on the ZL1. It gets the Magnetic Ride Control suspension from the Corvette ZR-1 and the Cadillac CTS-V, it borrows the dual stage exhaust system from the Corvette and it swipes the amazing Brembo brakes from the CTS-V, although these are tuned specifically for the Camaro. GM engineers spent a considerable amount of time lapping the Nürburgring, so it’s safe to assume the ZL1 is the best-balanced Camaro in history, not just the most powerful.

Inside, Chevy freshened up the interior for ZL1 duty. Gone is the deep dish steering wheel from last year’s Camaro, which fit my oddly-shaped hands perfectly. Seats are black leather with microfiber suede inserts and ZL1 logos embroidered on the headrests. A four pack of gauges sits atop the center console, and ZL1 cars get unique badging, door sills and alloy pedals. Just in case you want to hear something other than the satisfying rumble of a 6.2 liter V8, Chevy also includes a Boston Acoustics audio system.

It’s too early to speculate on cost, availability or delivery dates, but I’ll do it anyway. Expect the ZL1 to cost more than a $49,000 Mustang Shelby GT500, but not all that much more. Expect Chevy to build as many as customers want to buy (at least for a year or two), but expect to pay a premium if you want to be the first on your block with a ZL1 in the garage. As for the “when” part, I’d expect deliveries to start in the first quarter of 2012. It’s no secret that the end of the second muscle car era is fast approaching, so here’s some free advice: if you’re a Chevy guy, do whatever you have to do to scrape together the cash for a ZL1. Chevy’s not going to build them forever, and I seriously doubt we’ll see many more cars like the ZL1.

ZL1: Chevrolet Camaro Enters The Realm Of Advanced Performance Technology

2011-02-09

* LSA 6.2L supercharged engine will produce an estimated 550 horsepower (410 kW) and is matched with a six-speed manual transmission with a dual-disc clutch system
* Packed with performance technologies, highlighted by Magnetic Ride Control, and advanced materials – including a vented carbon fiber hood insert. Extensive aerodynamic development designed for high-performance driving
* Development ongoing, targeting launch at the beginning of 2012

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 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.

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.
