Times are around Spring Mountain.

Stage 1 – Stock Camaro SS
Best Lap Time: 2:05.10

Serving as the control group for the concept cars, these cars demonstrated the performance of factory-stock Camaro SS models, which include fully independent front and rear suspensions – with the rear suspension featuring a 4.5-link system that includes a unique, L-shaped upper control arm that attaches to the knuckle at one end and incorporates a ride bushing in the rear. The front suspension has a dual-ball strut system, with a direct-acting stabilizer bar.

Four-wheel disc brakes with Brembo four-piston calipers are standard, while an electric power steering system originally developed for the ZL1 has been standard on the SS since 2013. All Stage 1 cars ran the course on stock wheels and tires:

20 x 8-inch aluminum wheels and P245/45ZR20 tires in the front
20 x 9-inch aluminum wheels and P275/40ZR20 tires in the rear.

Stage 2 – Ultimate Street Camaro SS
Best Lap Time: 1:59.30

The 1LE package is offered on regular-production SS coupe models and features an exclusive package of transmission, chassis and suspension components tuned for enhanced performance. Many of the parts – as well as key parts from the supercharged Camaro ZL1 – are available as direct bolt-on enhancements to shave about 6 seconds off the stock Camaro SS’s lap time.

The components used to build the Camaro SS Ultimate Street Car include:

1LE sport suspension package (#23123397) – includes a larger, 27mm solid front stabilizer bar and 28mm solid rear stabilizer bar for improved body control; and revised toe links and rear shock mounts for improved on-track performance
1LE strut tower brace (#23120485)
1LE tires: Goodyear Eagle F1 Supercar G:2 – P285/35ZR20 (#9598378 left / #9598379 right)
1LE wheels: 20 x 10-inch front and 20 x 11-inch rear (#22798741 front / #22798742 rear)
1LE PCV system (#12653073)
ZL1 low-restriction air filter (#92229651)
ZL1 wheel hubs (#25954415)
ZL1 front brake kit (#22959672)
ZL1 rear brake kit (#23104466)
Chevrolet Performance short-throw shifter (#19299460 – suede / #23157703 – leather)
Chevrolet Performance exhaust system (#23206771).

Stage 3 –Ultimate Track Camaro SS
Best Lap Time: 1:56.43

Leveraging key components of the Camaro Z/28 – recipient of Motor Trend’s 2014 Best Driver’s Car award – the Ultimate Track Camaro SS concepts demonstrated the ultimate in track capability for SS models.

Along with the additional power supplied by its enhanced LS3 6.2L engine – featuring a camshaft kit and CNC-ported cylinder heads available from Chevrolet Performance – the Ultimate Track Camaro SS was 2.9 seconds faster than the Ultimate Street Camaro SS, and 8.7 seconds faster than the stock Camaro SS.

“With the Z/28 parts, the Camaro SS is transformed into an entirely track-focused machine,” said ****ens. “The steering is responsive and precise, allowing you to carve down to the apex with ease – and it confidently gets the power to the ground while exiting turns. Perhaps even more amazing is that the on-track transformation is accessible with parts that literally bolt on to any 2010-and-newer Camaro SS.”

The parts roster for the Ultimate Track Camaro SS includes:

LS3 Power Upgrade Kit (#19301990) – includes camshaft and cylinder heads, enabling 30-horsepower gain over the engine’s stock output
Z/28 suspension kit with DSSV® Dampers (#23464729)– a comprehensive suspension package that includes racing-derived spool-valve dampers, higher-rate coil springs, smaller-diameter solid stabilizer bars, and higher-rate suspension bushings
1LE strut tower brace (#23120485)
Z/28 helical differential (#23172755) – a racing-proven, zero-preload limited-slip designed for optimal corning capability and cornering exit traction. It includes the 1LE 3.91-ratio gear set
Z/28 differential cooler (#23216684 – kit with lines) – incorporates an integral heat exchanger, which eliminates the need for an external pump and related hardware
Z/28 aero components kit (#23489551) – includes a front splitter, Gurney lip moldings and a rear spoiler (2014-15 models only)
Z/28 brake ducts kit (#23252398) –channels cool, outside air to the front brakes
Z/28 rear spoiler wicker bill (#23200130) – enhances downforce capability when added to the rear spoiler that’s part of the Z/28 aero components kit
Z/28 air intake (#23454578) – features a conical air filter sealed to the bottom of the hood
Z/28 cat-back exhaust system (#22906768) – offers 26-percent reduced backpressure compared to the SS exhaust and a muscular sound
Z/28 exhaust adapters (#23454579) – to match the exhaust manifolds with the cat-back exhaust system
ZL1 wheel hubs (#25954415)
ZL1 front brake kit (#22959672)
1LE tires: Goodyear Eagle F1 Supercar G:2 – P285/35ZR20 (#9598378 left / #9598379 right)
1LE wheels: 20 x 10-inch front and 20 x 11-inch rear (#22798741 front / #22798742 rear)
1LE PCV system (#12653073)
Chevrolet Performance short-throw shifter (#19299460 – suede / #23157703 – leather).

What would you actually call the things that the Avalanche had, roll bars? Something else?

It would be a lot easier to stick it in the bed of a Silverado or Sierra like done on the SEMA vehicle than an SUV.
Sierra Denali should get a hardwood bed floor option. I said it.

And for the record, the trucks should have been the slightest bit more innovative, like the (first) Cheyenne concept.

2016 is on the way, and still no real variants worth writing home about...

Will we see the Ace Frehley Sonic at next year's SEMA?
arg arg arg

Speaking of Sonics, I would really like to see a production Rally Sonic and a real Z-Spec to compete with the Fiesta ST.

If the Cruze is relegated to mature buyers, Chevrolet's got to have something for the less mature. Sonic has spent almost an entire lifecycle grossly underutilized and unexploited.

That would be cool with the Emerald Green color.
The trim on the High Desert vaguely looks like a faux wood veneer in the med res photos, it's what reminded me of it.

I think it looks great. Way better than High Country.

So why not a lowered, "special handling package" truck? Either Silverado or Colorado sized?
My ZQ8 Sonoma was one of the most fun vehicles I've owned.
How about a smashed Silverado drift truck? Or just a slammed Silverado? Call it the Dumped Truck.

That's what people want to see at SEMA, not tape packages. People eat that kind of stuff up.

Why do people like the Silverado High Desert Concept??? Terrible color, terrible wheels, and hideous left over parts from the Avalanche parts bin. I don't get that truck at all.

The best looking trucks by a mile are the Silverado Toughnology Concept and the Colorado Sport Concept.

GM has such a huge after market catalog of engines, transmission, etc., to make some really bad ass concepts, just by swapping in engines and transmissions into current models. Sure it takes time, effort, and money, but I'm certain that a company the size of GM can do this in lieu of a fraction of a percentage of mediocre advertising that is costing them millions.
