Chevrolet announced official performance results and pricing information on Tuesday for the 2009 Corvette ZR1, the fastest Corvette ever built. Pricing will start at $105,000 for the ZR1, including an $850 destination charge and a $1,700 gas-guzzler tax, the automaker said. The price tag for the ZR1 is nearly $33,000 more than that of the 2008 Chevrolet Corvette Z06. In comparison, a base 2008 Chevrolet Corvette coupe starts at $46,950, including destination. A fully loaded ZR1, equipped with a $10,000 optional interior package and $2,000 chrome wheels, is priced at $117,000. The options package includes power-adjustable, heated and leather-trimmed sport seats with the ZR1 logo, side airbags, Bose premium audio system, navigation system, Bluetooth, power telescoping steering column and a custom leather-wrapped interior. Chevrolet said the 638-hp ZR1 with the 6.2-liter supercharged V8 sprints from zero to 60 mph in 3.4 seconds and confirmed the supercar has a top speed of 205 mph, “making it the fastest Corvette ever produced.” The 205 mph top speed was no secret, since Chevrolet had been touting that particular number for weeks. It noted that the ZR1’s 0-60-mph performance is 0.3 second quicker than the Corvette Z06. Chevrolet’s statement about the ZR1, entitled “Corvette ZR1 by the Numbers,” also contained EPA-estimated fuel economy numbers on the vehicle. Chevrolet said the ZR1 has an EPA-estimated fuel economy of 14 mpg in the city and 20 mpg on the highway. “They’re competitive with the Dodge Viper [13 city/22 highway] and the Porsche 911 GT3 [15/22],” said Chevrolet. However, the EPA has yet to post any official numbers about the ZR1 on its Web site. In early May, Corvette ZR1 chief engineer Tadge Juechter said on GMnext.com that the fuel economy of the ZR1 “will be somewhat less than a Z06.” The 2008 Corvette Z06 gets 15 mpg in the city and 24 mpg on the highway.
