C6 Corvette

Popular Mechanics Tests Corvette’s Fuel Efficiency

by Keith Cornett on June 15, 2009

 Popular Mechanics Tests Corvette's Fuel Efficiency

Those who look at the Corvette and see a gas guzzling V8 sports car are usually unaware that the sport car’s EPA highway mileage rating is 26. Corvette owners who regularly drive their cars know this number to be on the low side. So Popular Mechanics recently got behind the wheel of a new C6 to test what they call Corvettes “most amazing talent…its astonishing fuel economy”.

Popular Mechanics chose a route from a gas station in Santa Barbara, California north along US Route 101 to Santa Maria and then back, a round trip of about 140 miles. The Corvette was a C6 model equipped with a standard six-speed manual transmission. PM drove the Corvette on the freeway at 55 mph, 10 mph below the posted speed limit, using cruise control with the windows up, air conditioning off and vents open. The 18-gallon tank was filled with 91 octane gas.

At 55 mph, the Corvette’s tach showed a steady 1300 rpms, barely off-idle, but producing enough torque to maintain a constant speed on even some of the longer grades. According to the on-board computer, PM averaged 30.5 mpg with and average speed of 52.8 mph over the 142.8 miles. But it only took 4.358 gallons to refill the Corvette’s gas tank. That works out to 32.8 mpg!

So how does a sports car with a 6.2 liter 436 horsepower V8 get this kind of fuel economy? Popular Mechanics says the secret is the sixth gear in the transmission, which is an aggressive 0.50:1 overdrive that when combined with the 3.42:1 final drive ratio allows the engine to turn slowly at modest cruising speeds.

The availability of the low-end torque provided by the LS3 engine means that it doesn’t have to spin to high revs to make sure there is enough ft-lbs of torque on tap. Popular Mechanics compares this feat to the Ferrari F430 (EPA highway rating is 16 mpg) which believes the Italian sports car could not make the same trip without at least one downshift.

The thought of driving the Corvette at 10 mph under the posted speed limit sounds pretty boring though and the writers from Popular Mechanics said the same. Any vehicle driven conservatively will get better fuel economy than one driven hard and fast. That being said, Popular Mechanics sums up its fuel efficiency test by saying the Corvette’s “parsimonious performance likely can’t be duplicated by any other car with anywhere near the performance.”

Lastly, for you detractors out there that only see Corvette owners as out of touch with the environmental movement or being less green than say a hybrid owner, I urge you to visit the story at Popular Mechanics and read the comments coming from Corvette owners who share their real life stories of the Corvette’s most amazing talent – it’s astonishing fuel economy.

2009 Competition Sport Corvette

Thirty years from now Corvette collectors are going to talking about the two special edition Corvettes that rolled out of Bowling Green in 2009. That’s because the two qualities collectors covet – high performance and limited production – have all but guaranteed the GT1 Championship Edition and the Competition Sport Edition a special place in Corvette history.

According to Chevrolet literature, the Competition Sport package was built for the owner who attends driving schools and track events. The edition was available in both Z06 and Z51 coupe configurations and featured performance options like the differential cooler, NPP exhaust and heads-up display.

The Z51-equipped 1LT coupe version was priced at $55,655 while the Z06 1LZ model was listed for $77,500 including charges. Only 72 CSC Corvettes were built and here is the production breakdown:

Competition Sport Quantity
   
Coupe – Arctic White 13
Coupe – Blade Silver 39
Z06 – Black 10
Z06 – Blade Silver 10
   
Total: 72


2009 GT1 Championship Edition Corvette

The GT1 Championship Edition was built to commemorate the 10 years of Corvette Racing’s successful run in the American Le Mans series. That run included over 70 victories, eight GT1 Manufacturer Championships and five GT1 class victories at the 24 hours of Le Mans.

Essentially there were six versions of the GT1 Championship Corvettes built. The GT1 Championship Edition was available in Coupe, Convertible or Z06 models with your choice of Velocity Yellow or Black. And because it was a commemorative model, the GT1′s race inspired graphics feature Corvette Racing’s Jake mascot ghost-painted on the hood bulge as well as years of the championships and driver’s National flags.

Pricing for the GT1 Championship Edition started at $65,310 for the 4LT Coupe, $71,815 for the 4LT Convertible and $86,385 for the 3LZ Corvette Z06. Although 600 were planned for production, only 125 were built. Here is the production breakdown:

GT1 Championship Edt Quantity
   
Coupe – Black 24
Coupe – Yellow 29
Convertible – Black 7
Convertible – Yellow 10
Z06 – Black 17
Z06 – Yellow 38
   
Total: 125

Chevrolet Celebrates Production of the 1,500,000th Corvette

Another milestone was reached in the 56 year history of the Chevrolet Corvette. On May 28th, this Arctic White Corvette Convertible became the 1.5 millionth Corvette ever made.

Chevrolet Product Marketing Manager Karen Rafferty made the announcement of the milestone at a recent meeting of the Greater Atlanta Automotive Media Association. “The 1.5 millionth Corvette is a great example of how Chevy is America’s Brand,” Rafferty said. “For nearly 60 years we have built America’s Sports Car and this milestone is a solid proof point.”

Like its predecessors, the 1.5 millionth Corvette features a white exterior with red interior and a black top. The Corvette has a 3LT options package.

This C6 Corvette joins the other milestone Corvettes built previously. The first Corvette rolled off the assembly line on June 30, 1953 in Flint, Michigan. Twenty four years later, the 500,000 Corvette was built in 1977. The one millionth Corvette was built in 1992.

GM CEO Fritz Henderson Discusses Corvette's Future

GM CEO Fritz Henderson spoke out again on Corvette through another live chat on GM’s Fastlane blog. The comments on Corvette were the first from GM’s leader since the company entered bankruptcy proceedings earlier this week.

A participant named John asked if the “Corvette will survive as the V8 engined rear wheel drive icon we all love”.

Fritz Henderson’s response:

Yes. My wonderful baby is my 2005 Corvette coupe. We have more in store for the future and this iconic brand will retain its powerful place within the new GM.

May 2009 Corvette Sales

by Keith Cornett on June 3, 2009

The news about Corvette sales just keeps getting better. For the fifth straight month, Corvette sales were stronger than the month prior. Chevrolet dealers sold 1,643 Corvettes in May, a 14% increase over April’s 1,407 deliveries. The May 2009 sales figure was also the highest since 2,318 Corvettes were sold in September of 2008.

2010 Corvette Grand Sport Launch Control Tested in Dealer's Lot

We showed you how the 2010 Corvette’s Launch Control works from the GM video shown at the National Corvette Museum’s C5/C6 Bash back in April. On Thursday, one of GM’s preproduction 2010 Corvette Grand Sports was at Les Stanford Chevrolet in Dearborn, Michigan and demonstrated the new feature – in their parking lot!

The new Launch Control system is very easy to engage. Just put your manual Corvette’s traction control into competitive mode and push the throttle to the floor. The system will hold a predetermined RPM and when the driver dumps the clutch, the launch control system modulates engine torque 100 times per second to get the best traction.

Les Stanford was quick to point out that this was a GM car and not a customers car or a car that would be for sale. The best news is that had this been an actual customer’s Corvette, using the launch control system will not void the warranty.

Official 2010 Corvette Grand Sport Pricing Released

by Keith Cornett on May 29, 2009

Offical 2010 Corvette Grand Sport Pricing Released

We got word today from Dave Salvatore of Kerbeck Corvette that pricing for the 2010 Corvette Grand Sport has been released. When the Grand Sport was introduced at the National Corvette Museum in April, Team Corvette members Harlan Charles and Tadge Juechter both said that people will be pleased when the final price is announced. Having seen the numbers, we see again why Corvette beats all sports cars in the performance per dollar category.

2010 Corvette Grand Sport Pricing:

  • 2010 Grand Sport Coupe starts at $55,720 including DFC
  • 2010 Grand Sport Convertible starts at $59,530 including DFC

Going off the current year pricing, that’s $6,205 more than the base Coupe and $5,360 for the base Convertible. Taking into account that we are expecting to see a pricing increase on the base coupe and convertibles, as well as the fact that the Grand Sport takes the place of the Z51 option which costs $1,695 and you are essentially looking at $3,665-4510 upgrade for the new wide-body design, complete with Z06 brakes, tuned suspension and a better 0-60 mph performance of 4.0 vs 4.2.

A quick check on some of the forums show that people are generally pleased with the pricing of the new model. Considering that most garage wide body conversions cost around $10,000, this new model should sell well.

Pricing on the Corvette models for 2010 should be forthcoming shortly which will also include pricing for the Z15 GS Heritage Package which will be available sometime in the fall.

Thanks again goes out to Dave Salvatore for supplying us with the pricing. If you are interested in ordering a 2010 Corvette Grand Sport, give him a call at 877-537-2325 or visit Kerbeck Corvette.

Karvajal's Corvette ZX-1 Corvette Widebody Conversion

New York-based Karvajal Design has just recently launched a new Corvette conversion package called the ZX-1. The page comes in two stages with the first being a complete body conversion while the second stage addresses performance. After reading the specs and checking out some of the photos, our exuberance for the ZX-1 is about on par with the facial expression on the model pictured above.

The ZX-1 starts with widening the Corvette C6′s body from 72″ to 80″. A copious amount of LEDs are added both front and rear and a custom exhuast, rear diffuser and 19/20″ HRE Aluminum wheels complete the look. Underneath the widebody, Karvajal added a Magnuson supercharger to produce over 600 horsepower and Brembo disc brakes, a Pfaft coil-over suspension and a full under-body aero design complete the package.

Inside the Corvette ZX-1, buyers can choose to go with a leather interior trim or do a premium upgrade that includes alcantara race seats and door panels, aluminum sill plates, floor mats and a leather-wrapped flat bottom steering wheel.

Karvajal Designs plans to build 300 ZX-1s with packages starting at $69,900. Customers supply the donor Corvette. The very first Corvette ZX-1 was built using a 2007 Corvette C6 and that car was recently listed on ebay with a buy-it-now price of $185,000.

GM Delivers Corvette ZR1 to German Prince

by Keith Cornett on May 27, 2009

GM Delivers Corvette ZR1 to German Prince

Prince Albert von Thurn und Taxis recently took delivery of a new Corvette ZR1 in Bonstetten, Switzerland. The Prince is a descendant of one of Germany’s old and wealthy noble families and is an avid race car driver who currently drives a Lamborghini in the FIA GT European Championship and the GT3 Class with Reiter Engineering. Owning a Corvette ZR1 was reportedly a “must-have” for the Prince.

Prince Albert’s racing pedigree includes the current European Lamborghini Cup title, vice champion of the German ADAC GT Masters 2008 and a stint in the FIA GT European Championship behind the wheel of a Lamborghini. He also currently races with Reiter Engineering, using the German firm’s GT3-class Lamborghini Gallardo race car. Despite his racing success, we understand the car will be used for personal driving as no plans have been announced to race the American super car.

Prince Albert joins the list of race car drivers who have purchased a 2009 Corvette ZR1. Other notable race car drivers include Mario Andretti, Jimmy Johnson and Jeff Gordon.
