I took a trip to Detroit last week to tour the Pratt & Miller Corvette Racing facility and see the new C6.R being built for the GT2 class at this year's Le Mans--but that's another story. This story starts at the end of the race shop tour, where I got a special treat: the 2011 Chevrolet Corvette Z06 "Carbon" edition was making its debut.
The Z06 Carbon is the next logical step in Corvette Z06 evolution, pulling in the non-engine elements of the super-duper ZR1 edition.
For track use, the Z06 Carbon is the best balanced Corvette yet. It combines the lightweight and naturally-aspirated Z06 engine with the road-holding and braking of the ZR1, said Tadge Juechter, Corvette chief engineer.
The Carbon Z06 uses the Brembo carbon ceramic brakes of the ZR1 with model-specific dark gray metallic calipers. The Carbon also uses the same 20-spoke 19-inch front/20-inch rear wheels as the ZR1, but coated in black to set the car apart visually. Other mechanical features include Magnetic Selective Ride Control for the first time on the Z06 and enhanced cooling. The car also features a special carbon-fiber pattern engine cover.
The Corvette Z06 Carbon will be available in two colors: Inferno Orange and the all-new Supersonic Blue. Having seen this car in person, I can tell you that the blue is absolutely gorgeous--understated, dignified, and all business.
The Carbon edition also comes with black headlamps and mirrors, a ZR1-style body color spoiler, body color door handles, a carbon-fiber raised hood, and black carbon-fiber rockers and splitter. They took all the tricks from the ZR1 to reduce mass and aerodynamic lift. For track events, customers can also install the Euro-styled racing number stickers that come with each car. Thankfully, Chevy's delivering those in the trunk instead of on the car.
Corvettes get a bad rap for having cheap interiors, but that's not a fair gripe for this car. The Z06 Carbon’s ebony leather and suede interior is complemented by blue or orange seat stitching to match the exterior color chosen. Other features include a unique steering wheel emblem, sill plate and logoed headrest. The suede used on the steering wheel, shifter, seat inserts, armrests and doors add to the performance luxury feel. Seeing it up close and personal, it's a really nice interior.
But if you're not lucky enough to get your hands on a Carbon edition, there will be an optional Z07 performance package that includes the same mechanical upgrades as the Carbon, and you can add that option to a regular 2011 Z06. This package also includes 20-spoke wheels and all the chassis and cooling upgrades.
For the rest of the Carbon goodies, you will be able to order a CFZ Z06 carbon-fiber package that includes the black carbon-fiber rockers, splitter and roof panel with the full-width body color spoiler. You can get the carbon-fiber goodies with or without the Z07 package on regular Z06 models.
The 2011 Corvette Z06 Carbon Limited Edition, as well as the new Z07 and CFZ Z06 option packages will be available in late summer of 2010.

History of the Buick " Grand National "
Grand National, T-Type and GNX
In 1982, the Regal Grand National debuted, which was named for the NASCAR Grand National racing series. Buick had won the Manufacturers Cup in 1981 & 1982, and wanted to capitalize on its success - "What wins on Sunday, sells on Monday". These 1982 cars were not painted black, which may confuse those not familiar with them. All started out as charcoal gray Regals that were shipped off to a subcontractor for finishing.
Originally intended for a run of 100 units, Cars and Concepts of Auburn Hills, Michigan, retrofitted 215 Regals with the GN package. Most obvious was the light silver gray firemist paint added to each side. Red pinstripes and billboard shadow lettering proclaiming "BUICK" were applied. The wheel opening moldings and rocker panel moldings were blacked out using black vinyl tape. Finally, a front air dam and rear spoiler were installed. On the inside, special "Lear-Seigler" seats were installed. These seats are fully adjustable and were covered with silver brandon cloth with black vinyl inserts. The front seat had Buick's "6" emblem embroidered onto them. To finish it off, a special clock delete plate was added to the instrument panel which contained the yellow and orange "6" logo and the words "GRAND NATIONAL BUICK MOTOR DIVISION."
The '82 GN came with a naturally aspirated 4.1 L V6 engine with 125 hp (93 kW) at 4000 rpm and 205 lb·ft (278 N·m) of torque at 2000 rpm. Of the 215 Regal Grand Nationals produced in 1982, a handful were based on the Buick Regal Sport Coupe package with the turbocharged 3.8 V6 engine with 175 hp (130 kW) at 4000 rpm and 275 lb·ft (373 N·m) of torque at 2600 rpm. There were only 2022 Sport Coupes produced in 1982, and the number of cars with both the GN and Sport Coupe packages is estimated to be less than 50.
For 1983, there was no Grand National. The Sport Coupe model was renamed the T-Type; 3732 were produced (190 hp (140 kW) at 1600 rpm and 280 lb·ft (380 N·m) of torque at 2400 rpm). The T-Type had been used on other Buicks, starting with the Riviera in 1981 (in 1979 and 1980, it was the S Type). The 1983 Regal T-Type featured tube headers, Hydro-Boost II brakes, 200-4R 4-speed overdrive trans and 3.42 rear axle (7.5").[3]
In 1984 the Grand National returned in all black paint. The turbocharged 3.8 L became standard and was refined with sequential fuel injection, and boosted 200 hp (150 kW) at 4400 rpm and 300 lb·ft (407 N·m) of torque at 2400 rpm. Only 5,204 Turbo Regals were produced that year, only 2000 of which were Grand Nationals.
In 1986, a modified engine design with intercooling boosted the performance even further; in 1987 it reached 245 hp (183 kW) and 355 lb·ft (481 N·m) of torque. Buick dropped the T-Type package for Regal in 1987. There were only 7,896 Turbo Regals produced in 1986. In 1987, when Turbo Regals reached their peak in popularity, a total of 27,590 Turbo Regals were produced through December.
In 1987, a lightweight WE4 (Turbo T) option was offered. Only 1,547 of this variant were produced. They were painted black and treated to the same blackout package as the Grand National, including bumpers, grille, headlight and taillight trim. The differences between a WE4 and the Grand National were the interior trim package, wheels, exterior badging, aluminum bumper supports, and aluminum rear brake drums as opposed to the Grand National's cast iron. The rear spoiler was only available as a dealer installed option. 1987 was the only year that the LC2 Turbo option was available on any Regal, making it possible to even see a Limited with a vinyl landau roof and a power bulge turbo hood. The 1987 model would be the end of the manufacture of the RWD "G-Body" Regal, but GM had to extend the build of the Grand National to meet customer demand.
For the final year, 1987, Buick introduced the GNX at $29,000. Produced by McLaren/ASC, Buick underrated the GNX at 276 hp (206 kW) and a very substantial 360 lb·ft (488 N·m) of torque.[4] This was created to be the "Grand National to end all Grand Nationals." Changes made included a special Garrett turbocharger with a ceramic-impeller blowing through a more efficient intercooler and a "CERMATEL (Ceramic/Aluminum) coated" pipe connecting the intercooler to the engine. A GNX specific EEPROM, low-restriction exhaust with dual mufflers, reprogrammed Turbo Hydramatic 200-4R transmission with a custom torque converter and transmission cooler, and unique differential cover/panhard bar included more of the performance modifications. Exterior styling changes include vents located on each front fender, 16 inch black mesh style wheels with VR-speed rated tires, and deletion of the hood and fender emblems. The interior changes of the GNX included a serial number on the dash plaque and a revised instrument cluster providing analog Stewart-Warner gauges, including an analog turbo boost gauge. GNX #001 is the 1986 prototype currently owned by Buick and sometimes makes appearances at car shows around the US. The GNX had a ladder bar that ran from the mid-section of the car to the rear axle, so as to increase traction. This is also the reason why a GNX will actually lift the rear end up when the car is about to launch heavily.

The stealthy appearance of the all-black GNX and Grand National, coupled with the fact that the Grand National was initially released during the height of Star Wars fever, earned it the title Darth Vader's Car (Car and Driver covered the GNX model's introduction with the headline "Lord Vader, your car is ready," a phrase more recently attributed to the Maybach Exelero). The line was also used with the 1994 Chevrolet Impala SS years after the GNX was discontinued.
