Chevrolet Introduces New ‘COPO’ Camaro

Concept evokes the spirit of special-order models for Stock Eliminator competition

LAS VEGAS – The COPO Camaro is back at Chevrolet, as a concept designed to the specifications for NHRA Stock Eliminator drag racing competition.

“The COPO Camaro is a proof of concept for what a Chevrolet Stock Eliminator entry could look like,” said Jim Campbell, GM U.S. vice president of Performance Vehicles and Motorsports. “And it is a clear indication that Chevrolet intends to homologate the Camaro for sportsman drag racing.”

The COPO concept vehicle is designed to accommodate more than one engine option, including a naturally aspirated 427 engine (7.0L) – the same displacement as the original COPO Camaros from 1969 – and a supercharged 327 (5.3L) engine. Among the many racing-specific features and equipment is a conversion from the Camaro’s standard independent rear axle to a solid axle, as well as a full chrome moly roll cage.

The basic content for the COPO Camaro Concept includes:

  • Provisions for two engine configurations (see below for details)
  • Provisions for a Powerglide two-speed automatic transmission, a three-speed automatic or a five-speed manual
  • High-rise cowl-induction hood
  • Custom Aeromotive fuel system, with a fuel cell and integral high-pressure fuel pump
  • Full, chrome moly roll cage
  • Coil-over front suspension with Strange Engineering adjustable struts
  • Custom rear suspension, based on NHRA requirements, with Strange Engineering shocks, Panhard bar and stabilizer bar
  • Strange Engineering S-9 solid rear axle with aluminum third member, 35-spline spool, 35-spline axles and 4.10 gear set
  • Lightweight, COPO-specific racing wheels
  • 29×9-inch rear radial racing slicks and 4.5x28x15-inch front tires
  • Manual steering system

Strange Engineering lightweight racing brakes system with standard line lock. The interior is all business, with most sound deadening and power accessories deleted. Instead, there is pair of racing bucket seats (and no rear seat), a safety harness for the driver, a competition floor shifter and Chevrolet Performance gauges by Auto Meter.

The engines

Intended for NHRA’s various Stock Eliminator classes, the COPO Camaro concept has provisions for two distinct engine packages – each built to conform to class guidelines. The details below outline the core specifications of each engine and their intended classes.

The concept vehicle is powered by a prototype version of the supercharged 327 engine, featuring an LSX cylinder block.

The COPO legacy

Since 1955, NHRA Stock Eliminator has been a straight-line proving ground for the quickest cars to come out of Detroit. Within Stock Eliminator, there are many classes, all defined by the ratio of vehicle shipping weight and the assigned horsepower factor. Because of this tightly monitored set of rules and historically brutal competition, Stock Eliminator is the ultimate test for factory muscle cars.

From the “Fuelie” ’57 Bel Air to the ’62 409 Impala and countless muscle cars that came later, Chevrolet has enjoyed a long, dominant position in this sportsman drag racing category. None of the cars, however, have dominated both the track and muscle car folklore like the legendary COPO Camaros produced in 1969.

In the Sixties, COPO was the acronym for Central Office Production Order, within Chevrolet’s vehicle special-order program. Although normally used for fleet orders of trucks and company-owned cars, it was manipulated by a few performance-minded dealers to order vehicles with larger engines than were available in regular-production models – mostly with the intent of getting them to Stock Eliminator racers.

By pushing Chevrolet’s Central Office Production Order special-order program to its limit, a number of dealers were able to get 427-cubic-inch big-block engines installed in a handful of Camaros, when the largest official engine available was a 396. Two versions of the 427 engine were wrangled out of the factory: COPO 9561 was the Corvette-based L-72 edition with an iron cylinder block and COPO 9560 was the racing-designed ZL1 engine with a lighter aluminum cylinder block.

The COPO Camaros opened up the NHRA rulebook to some exciting combinations for Camaro, helping keep Chevrolet at the top of the ultra-competitive form of motorsports. In fact, they were not only competitive in NHRA Stock Eliminator when new, but still hold the national ET and MPH records in several classes.

Camaro is SEMA’s Hottest Car for Second Consecutive Year

LAS VEGAS – For the second year in a row, the Chevrolet Camaro is the “hottest car” at the SEMA Show in Las Vegas. The SEMA Award recognizes the most accessory-friendly vehicle, based on the volume of aftermarket parts exhibited at the annual showcase of automotive performance and personalization.

The SEMA Award was first handed out in 2010, which not only makes Camaro a two-time winner, but the only car to receive the award. Its selection reflects the aftermarket industry’s enthusiasm and continued investment in America’s most popular sports car.

Camaro posted 6,119 sales in October, again leading the segment and topping the next-closest competitor nine of 10 months so far in 2011 – with sales up nearly 7 percent in the first 10 months of this year.

“After more than two years on the market, the Camaro continues to inspire creativity and Chevrolet is thrilled to see that expressed in all the wonderfully personalized examples here at the SEMA Show,” said Chris Perry, vice president, Global Chevrolet Marketing and Strategy. “Camaro has always been a car customers love to personalize and we are doing all we can to support them and the aftermarket industry with parts and accessories that help turn their dreams into reality.”

Along with the examples displayed by aftermarket manufacturers and customizers at the SEMA Show, Chevrolet brought its own contingent of customized Camaro concepts to Las Vegas, demonstrating the diverse range of personalization and performance possibilities. They include:

COPO Camaro – A conceptual exploration of a factory-built Stock Eliminator race car and the spiritual successor to the legendary special-order models from 1969.

Camaro Hot Wheels® – This full-scale interpretation of a Hot Wheels toy is inspired by the “Custom Camaro” model, which was part of the original release of 16 Hot Wheels toys in 1968 – including a modern take on the chrome-style “Spectraflame” exterior finish.

Camaro Red Zone – A design statement in the new-for-2012 Crystal Claret exterior color and achieved with current and future accessories – and it debuts a new, heritage-inspired stripe graphic that will be available soon.

Camaro Synergy Series Concept – Using the best of the best Camaro accessories matched with a distinctive silver exterior with red accents, it’s the latest in the Synergy concepts that have debuted at SEMA. Chevrolet will be listening to the reaction it receives at SEMA, as it could be brought to production.

Camaro 1LE Concept – The legendary 1LE designation returns to the Camaro as a concept intended to carve up road courses. While only a concept, it borrows production components from both the Camaro SS and forthcoming Camaro ZL1 to deliver a competition-ready package.

Camaro ZL1 Carbon Concept – This concept incorporates all the technology and performance of the Camaro ZL1 – which goes on sale in 2012 – with an added layer of carbon fiber to add a decidedly sinister-looking element of form to a car that’s all about function.
