It takes some skill and balls to drive that car like that with a wet track. I have had my back end swing out at 10 MPH don't even want to know what it feels like at 80+ like it happened on the Z/28.

Too bad after all this wait we get a "controversial" video to chew on....If the video for the Z/28 was "officially" released, I would think there would be some supporting information/details along with it, at the very least an explanation of weather, track, safety factors that affect the time...dunno, just sayin'....

It is an Official Video release from Chevrolet.

In developing the 2014 Chevrolet Camaro Z/28, engineers were almost entirely focused on track capability, and it appears their endevors have paid off as the car has now lapped Germany’s Nürburgring, one of the toughest tracks on the planet, in a time of 7:37.47.
That might not sound very impressive when the production car lap record stands at just 6:57, but remember that the Camaro Z/28 achieved this feat without the added traction of all-wheel drive or the quick shifts of a dual-clutch gearbox, but with a good ol’ pushrod V-8 mated to a six-speed manual and spinning the rear wheels only.

Making the result even more impressive is the fact that there even was some rain falling on the ‘Ring during the attempt. Based on previous testing, Chevy is confident the Z/28 could shave a further 6.0 seconds from the lap time.

"One of the challenges of testing at the 'Ring is that the track is so long that conditions can change radically in a single lap," said Al Oppenheiser, Camaro chief engineer. "Adam Dean, the development driver for Z/28, did a heroic job driving in deteriorating conditions.”

Some of the cars it beats include the Type 991 Porsche 911 Carrera S and Audi R8 V10. It also beats the more powerful Camaro ZL1 by about 4.0 seconds.

If you've forgotten, the key stats of the new Z/28 are a 500-horsepower 7.0-liter LS7 V-8, a Tremec six-speed manual transmission, a limited-slip differential, carbon ceramic brakes, Pirelli P Zero Trofeo R tires, Recaro seats and a 300-pound weight advantage over the 4,120-pound ZL1. Oh, and there’s no air conditioning as standard.

Testing at the Nürburgring is a key step in the development of numerous Chevy performance cars. A total of 10 hours and nearly 1,000 miles were covered on the track for the Z/28. These hours were part of the grueling ‘24-Hour Test’ that simulates a full year's worth of track use at the hands of an owner. The 24-Hour Test is broken into a number of segments over the course of several days, and at different tracks. Crucially, each valid test lap must be run within 2 percent of a target lap speed to count toward the 24-hour total.

Pricing is yet to be announced for the Z/28 but Chevy has said it will be priced north of the ZL1's $56k sticker.

Interesting.

Track-capable Camaro Z/28 Validated at Nürburgring


2013-10-15

◾Z/28 undergoes 10 hours or 1,000 miles of testing at Nordschleife
◾Fastest lap completed in 7:37.40 in rainy conditions

DETROIT – Chevrolet today revealed a video of the all-new, 2014 Camaro Z/28 lapping Germany’s challenging Nürburgring road course in 7:37.40, a time comparable with some of the world’s most prestigious sports cars.

The Z/28’s lap is four seconds faster than the Camaro ZL1, and beats published times for the Porsche 911 Carrera S and the Lamborghini Murcielago LP640. The Z/28’s lap was completed on less-than-ideal conditions, with damp pavement and pouring rain near the end of the run.

"One of the challenges of testing at the 'Ring is that the track is so long that conditions can change radically in a single lap," said Al Oppenheiser, Camaro chief engineer. "Adam Dean, the development driver for Z/28, did a heroic job driving in deteriorating conditions. Based on telemetry data from our test sessions, we know the Z/28 can be as much as six seconds faster on a dry track."

In terms of lap times, the Z/28’s improved speed came from three areas:
◾Increased grip: The Z/28 is capable of 1.08 g in cornering acceleration, due to comprehensive chassis revisions
◾Increased stopping power: The Z/28 features Brembo carbon-ceramic brakes capable of 1.5 g in deceleration, and consistent brake feel lap after lap
◾Reduced curb weight: The naturally aspirated Z/28 weighs 300 pounds less than the supercharged Camaro ZL1, with changes ranging from lightweight wheels to thinner rear-window glass.

The heart of the Z/28 is the 7.0L LS7 engine. The LS7 uses lightweight, racing-proven, high-performance components, such as titanium intake valves and connecting rods, CNC-ported aluminum cylinder heads and a forged-steel crankshaft to help produce an SAE-certified 505 horsepower (376 kW) and 481 lb-ft of torque (652 Nm). Air-conditioning is available, but only as an option.

A close-ratio six-speed manual transmission is the only transmission offered and power is distributed to the rear wheels via a limited-slip differential featuring a helical gear set, rather than traditional clutch packs. The new design enables the driver to apply more power and get through corners faster, by making the most of the capability of individual-wheel antilock brake function during corner entry braking, mid-corner speed and corner-exit traction.

The team spent a week at the Nürburgring as part of the Z/28's performance-validation regimen, accumulating a total of 10 hours and nearly 1,000 miles on the track. Each lap took less than eight minutes to complete, despite having to overtake slower traffic at times. These hours are part of the grueling 24-Hour Test, which simulates a full year's worth of track use of track days or amateur-level competition at the hands of an owner.

“Passing the 24-Hour Test is a requirement for all cars we call 'track capable,’” said Wayne McConnell, director of global vehicle performance. "The test pushes the car at 10/10ths on the track for a total of 24 hours. During the test the only mechanical changes allowed are replacing the brakes and tires.”

The 24-Hour Test is broken into a number of segments over the course of several days – and even at different tracks – to evaluate performance in precisely measured and carefully monitored increments. Crucially, each valid test lap must be run within 2 percent of a target lap speed to count toward the 24-hour total.

The 24-Hour Test was first used in the early 1990s for the fourth-generation Corvette. Back then, the 300-horsepower Corvette was Chevrolet’s most powerful vehicle, and the 24-Hour Test measured 15 channels of data. Today, the 2014 Camaro LS offers a 323-horsepower V-6, while the Camaro Z/28’s racing-proven LS7 7.0L small-block V-8 delivers 505 horsepower, and the 24-Hour Test measures 130 channels of data.

“Our cars' performance and capability have advanced tremendously in the past 20 years, which required us to continually improve the parameters of the 24-Hour Test," said McConnell.

"Today’s test pushes the car harder than the vast majority of customers ever will. As a result, when we call a car ‘track capable’ we are confident that it will perform reliably and consistently for our customers.”

Nice info...but it sounds like their window of opportunity and all the 24hr test business has closed their chance to get the 6 second better time....??

[Mikamaro]

It amaze me to look at the pictures and see that the car has no Roll cage nor harness.
his only strapped with the 3 point belt...wow!

Absolutely!
Can't win them all...To much to do in little time.
Quote -''Crucially, each valid test lap must be run within 2 percent of a target lap speed to count toward the 24-hour total.'' (which equals to less then 10 sec per lap.)

The perfect run will be for next time...if they come back with the Z/28.
I doubt it now.

Sounds like they are pretty confident that without the unfortunate wet conditions the car would have done 7:31.5...Would have moved it way farther up that list...

Damn rain!!!!!.....lol....

[shaffe]

Wish they had better conditions, but still look at the time they produced. That's a camaro in the same class as Porche's Ferraris and Audis. That's damn impressive

It also meant that posting the hypothetical dry Lap at 7:31:47, all other 50-75 laps would have had to be under 7:40.00 to count for the 24 hours test... That would of been a very hard & drooling job, not counting the risk of a crash.

[L99CAMA2011]

On a track that takes lives GM showed us that this car has very capable handling and that driver has a lot of talent and skill. As long as the ring run is I am sure the Z28 can break into the high 7:20 range.

...That would make the Z/28 number "28" on the list...what a coincidence...lol

[Mikamaro]

QUOTED: -''Based on telemetry data from our test sessions, we know the Z/28 can be as much as six seconds faster on a dry track."

So they did do it but can't use it since most of the track times were done under wet conditions and they needed to accumulate more than 50 laps for the 24 hours test.
