Pretty sweet. Hopefully they go through with it. Shame its likely going to be super overpriced.

Chevrolet Wants to Make the Camaro SS a 10-Second Car with Factory Parts

The Chevrolet Camaro is no stranger to sub-10-second times on the drag strip. In fact, it's no stranger to sub-nine or even sub-eight, if you count some of the maniacal creations that have been built out of every generation of the muscle car. But now, for the first time, Chevrolet has created a factory-based Drag Race Development Program specifically for testing and building out production sixth-generation Camaro SS models with its sights set on the 10-second mark. And this camouflaged racer is Chevy's test car.

Although you soon will be able to buy a massively powerful Camaro ZL1 from a dealer or, if you're lucky, one of the 69 just-announced 2017 COPO Camaros, Chevrolet knows that many of the cars that line up at the tarmac start out as regular production models like the SS. They are crafted into tire-shredding monsters by owners who love the do-it-yourself spirit of the sport. It's one thing to buy a car that's fast; it's another to buy a car and make it fast. Members of the latter group are the people Chevy is aiming at with its Drag Race Development Program.

With this SS, which starts with a 455-hp LT1 V-8, Chevy tried to follow the same progression line a normal racing enthusiast would take. Some of the initial modifications included swapping out the rear differential for one with a higher ratio and adding a cam-and-heads package. The team also added Chevrolet Performance air induction and exhaust systems and fitted smaller brakes, which allowed for smaller, 16-inch wheels, which allowed for bigger slicks.

After more testing, Chevrolet switched to a higher-stall torque converter, stating that this upped the stall speed to 4200 rpm, 30 percent faster than stock. With power up to about 530 horsepower, or 600 with what Chevy vaguely calls a "power adder," the next modifications were half-shafts and the prop shaft from the sixth-gen ZL1, plus a 250-millimeter, 3.73-geared rear axle from the fifth-gen ZL1.

To date, Chevrolet said it has done more than 100 quarter-mile passes with the test car. The claimed fastest time for the SS-based dragster is 10.685 seconds at 125.73 mph. That is definitely improved from the 12.3-second time we recorded for a stock SS, but Chevrolet is going to have to do better if it really wants to raise some eyebrows.

"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, the division's director of 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."

Damn you. Was just coming in here to post.

The press release has more info. It's a cam/head package car..

PAHRUMP, Nev. – For 50 years, the Camaro and the quarter-mile have stuck together like a drag slick on a well-prepped starting line, and Chevrolet is pushing that winning legacy forward with the new Camaro SS Drag Race Development Program and the 2017 COPO Camaro.

The Camaro SS Drag Race Development Program explores the quarter-mile capability of the Gen Six Camaro with concept parts designed to support 10-second elapsed times in a production-based model. The COPO Camaro offers the first look at the factory-built race car program for 2017.

“From sportsman classes to the pro ranks, Camaro has been one of the most popular cars ever to launch down the drag strip,” said Jim Campbell, GM U.S. vice president of Performance Vehicles and Motorsports. “For 50 years Chevrolet has supported Camaro drag racers and these new SEMA vehicles demonstrate our commitment to the sport, with parts development and the advancement of the historic COPO Camaro program.”

That commitment has helped put Camaro drivers in the winner’s circle, including seven class wins out of eight NHRA Stock classes and a Super Stock class win at the 2016 Chevrolet Performance U.S. Nationals in Indianapolis. COPO Camaro racer Jeff Lopez was the Stock Eliminator champion.

Drag Race Development
The Camaro SS Drag Race Development Program was created to develop performance parts for 2016+ Camaro models. A test vehicle was built to mimic the typical stair-step enhancements many amateur racers make with their production Camaro SS models, including swapping the differential for a numerically higher ratio and adding horsepower-building components such as a cam-and-heads package to push the SS’s LT1 engine to more than 530 horsepower — and about 600 horsepower with a power adder.

“More than simply achieving quick ETs in the Camaro, we are exploring the supporting components that help the car to go quicker with great durability,” said Mark Dickens, director, Performance Variants, Parts and Motorsports Engineering. “We’ve tested stronger axles and chassis components aimed at improving launch and traction attributes.”

Engineers have made more than 100 passes down the quarter-mile with the development car, including the evaluation of DOT-approved racing and slick tires and a variety of drivetrain combinations.

The engineering team also tested a higher-stall torque converter for greater launch capability, increasing the stall speed to 4,200 rpm with the LT1 engine. That’s approximately 30 percent higher than the stock converter. Along with a custom transmission calibration, the prototype converter allowed the car to launch harder, which improved the 60-foot time significantly and thereby improved the quarter-mile elapsed time.

The best performance to date includes:

60-foot time of 1.425 seconds
Eighth-mile time of 6.764 seconds at 100.85 mph
Quarter-mile time of 10.685 seconds at 125.73 mph

Consistency in the performance tests came in large part from the Camaro SS’ production eight-speed paddle-shift automatic transmission, which fired off quick, immediate upshifts.

“We worked this car just as hard as any serious racer would,” said Dickens. “We made pass after pass, pushing it harder, and were amazed at the capability and durability that came straight off the assembly line.”

To support the greater horsepower and channel it to the ground durably, the engineers borrowed some heavy-duty, proven parts from the Gen 6 Camaro ZL1 including the half-shafts and prop shaft and the beefier Gen 5 ZL1 and Chevrolet Performance driveline upgrade with a 250mm, 3.73-geared rear-axle center section. They nicknamed it “Gravedigger,” because they haven’t been able to break it. The parts might be included in a range of Gen Six Camaro drag-racing parts Chevrolet is evaluating.

Additionally, the test car was fitted with Chevrolet Performance air induction and exhaust systems, as well as a “small” brake system that features small-diameter brake rotors that fit inside the test car’s 16-inch rear racing wheels and slicks.

While the production Camaro SS features 20-inch wheels, optimal traction on the drag strip is achieved with racing slicks that feature taller sidewalls. They wrinkle slightly at launch as the slicks bite the starting line, reducing the chance for traction-killing tire spin. Smaller-diameter racing wheels typically don’t fit over large-diameter production brake rotors.

“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 Dickens. “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.”

Like other Chevrolet development vehicles, the Drag Race Development concept wears a camouflaged exterior. There is, however, no disguising its performance capability when it’s lined up at the Christmas tree.
