Chevy is showing off a new drag racing concept and the 2017 COPO Camaro.

Chevrolet is heading to the SEMA Show in Las Vegas with two new Camaro models that are ready to tackle to the drag strip.

The first of the two new models is the Camaro SS Drag Race Development concept. In a nutshell, the concept is a rolling test bed for drag-racing specific parts that Chevrolet might eventually offer for its sixth-generation Camaro.

Starting with a stock Camaro SS, engineers have swapped out a number of components on the show car in order to squeeze out every ounce of performance on the drag strip. Improvements currently include a new rear differential, engine improvements that boost output to as much as 600 horsepower, a higher-stall torque converter and a small brake package that allows the use of drag radials mounted on 16-inch wheels.

So far the prototype's best run has been 10.685 seconds at 125.73mph. Moreover, the concept has earned the name "Gravedigger" because nothing has broken in the 100+ passes conducted to date.

"The Camaro SS Drag Race Development concept is a work in progress, but Chevrolet is serious about developing parts and packages tailored for drag racers," said Mark Dickens, director, Performance Variants, Parts and Motorsports Engineering. "As we continue to develop the car, we'll be listening intently to customers' reactions to it and what they believe would help them the most on the drag strip. This is only the beginning."

Chevy didn't mention when parts from the Camaro SS Drag Race Development program might be available to the general public.

Continuing its line of COPO cars that was revived in 2012, Chevy is also showing off its latest track-ready COPO Camaro at the 2016 SEMA Show. Designed for the NHRA's Stock Eliminator classes, each COPO Camaro comes with a lightweight suspension, upgraded rear axle, light-weight, unassisted disc brakes, a manual steering rack, fuel cell and unique wiring harness.

Buyers will be able to select from a number of LS- and LT-based engines, including a supercharged 350, a naturally aspirated 427 and a direct-inject 376. All engines are mated to a TH400 three-speed automatic.

Chevrolet will produce just 69 units of the 2017 COPO Camaro. Serial No. 1 will be auctioned off at the Barrett-Jackson Scottsdale in January 2017, with proceeds to benefit United Way.
