Chevrolet Camaro Z28 is GO!
Supercharged 556hp Camaro to take on Shelby GT500
January 01, 1900
GM design chief Ed Welburn confirmed to us at the Frankfurt Show that the Camaro Z28 program is back on track. As we reported back in April, the Z28 was basically completed, with the design signed off, but the final engineering and certification work was put on hold as GM's financial situation spun out of control.
With GM now out of bankruptcy, the Z28 program has been restarted. Why? Insiders say the Z28 business case now makes sense because the new UAW contracts have reduced the labor costs on the car to the point where GM feels it can price it competitively -- and far enough away from Corvette. That's the good news. The bad news is EPA certification and GM durability requirements mean the Z28 is unlikely to go on sale until late 2011.
Our images are very close to the final signed-off design, based on photos of a scale clay model we've seen. Key details to note are the deeper front bumper fascia, with larger front aperture under the grille and the spotlights mounted in deep vents on either side. The Z28 also gets a different grille mesh compared with that of a standard Camaro.
At the rear is a taller lip spoiler that runs the full width of the car. A new rear-bumper fascia features a deeper section with integrated exhaust outlets. The wheels are 20-inchers with an aggressive "tuning-fork" five-spoke pattern.
A new hood features a large, forward-facing scoop. Underneath is the 6.2-liter supercharged LSA V-8 that also powers the Cadillac CTS-V. As we have already confirmed, this is quite a powerplant, delivering 556 horsepower at 6100 rpm and 551 pound-feet of torque at 3800 rpm.
The near-4300-pound CTS-V thunders from 0 to 60 mph in 4.1 seconds and nails the quarter mile in 12.3 seconds (automatic) or 12.4 seconds (manual). Top speed is limited to 175 mph in the auto (to preserve the tranny), but the manual will storm to an autobahn-melting 193 mph. As the Z/28 will weigh 200 to 300 pounds less than the CTS-V, it may nail 60 mph in 3.9 seconds and run the quarter in the very low 12s. This Z28 could be the fastest Chevy ponycar since the legendary ZL-1-powered COPO 9560 Camaros built 40 years ago.
The Z28 is likely to only be available with a six speed manual transmission, unless GM can piggyback some of the car's certification on work already done for the CTS-V to get the automatic into the range at low cost.

because its the heritage. ZL1 belongs to the Vette's. Z28 belongs to the camaro... and our 2010 is getting 25mpg highway, which is great, but thats not why we bought the car... bought it to go along with the 71 Z-28 and the 02 Z-28
Find me one Camaro Z-28 that is a 6 cylinder of any form.
what about the z-24? should that be an s10?

no, the ZR1 belongs to the vette. the ZL1 was the optional "dragpack" in the first gen camaros that put a BB 427 in them. it was and is THE camaro to own.
however, i think they are fine with the current lineup. RS has always been base, when the SS and Z came out, the SS was mid trim, the Z was top dog. back to the basics

ZL-1 was an option code on the Chevy Corvette and Camaro in 1969. It was a Regular-Production Order (RPO) for the 'Vette, but for the Camaro it was a Central Office Production order (COPO).
It consisted of an L88 427c.i. engine but replaced the normal cast-iron block with an aluminum one, and saved 100lbs. in the process. This lead to 50/50 weight distrubtion for both models. To make up for the fact that aluminum is weaker than iron, the block was beefed up substantially. A dry-sump oil system was used, and the stock camshaft was replaced with a longer duration one. The ZL-1 weighed just over 500lbs. total and could produce 585hp @ 7000rpm at the crank. Fuel shutoff occured at 7100rpm. Torque output was officially rated at 460ft-lbs, but it is/was actually over 500ft-lbs.
A complete ZL-1 'Vette, of which only 2 were produced, had a dry weight of just under 3,000lbs. In addition to the 2 Corvettes produced with the ZL-1, 69 Camaro's also recieved the engine. All ZL-1-equipped cars featured the M22 "Rock-Crusher" close-ratio 4-speed transmission, although one ZL-1 test car had a "beefed-up" 3-speed automatic.
A grand total of 500 ZL-1 engines were produced in order to homologate it for racing.
Zora Arkus-Duntov drove a ZL-1 Corvette down the 1/4-mile in 12.1 seconds at 116mph. This car was equipped with an M22 4-speed tranmission, a 3.70:1 Positraction rear-end, and road race tires. In order to fit the tires, a set of fender flares had to be installed. Both ZL-1 'Vettes came with a set of fender flares in the passenger compartment. The tires had to be bought separatley. Zora managed to pull a full 1.0g on the skid pad with this 'Vette.
Zora took another ZL-1 'Vette, this one with headers and drag slicks, which, I'd like to point out, are about as good as modern street tires, through the 1/4-mile in 10.5 seconds at 133mph.
The 1st car had a top speed over over 160mph. The 2nd could make it to 140mph. However, with dealer-installed 2.76:1 gears, to ZL-1 Corvette could push 200mph with relative ease.
Craig Lewis wrote:The Z, in my opinion, should have the dry sump 6.2 out of the grand sport with light weight details and a monster brake option. Maybe evern a little extra room for tires. It should cost more than the base SS.
The LS9 should be an option on the SS with no additional nomentclature or extra bling. A sleeeper, if you will.
RS should remain an appearance package available on all models.
