Callaway Cars today announced power numbers and performance for the flagship model in their performance car lineup. Equipped with Callaway’s GenThree Supercharger, the Corvette Z06 now produces 757 bhp @ 6,200 rpm and 777 lb-ft @ 4,500 rpm (SAE). A launch to 60 mph is now achieved in 2.8 seconds, and a quarter-mile in 10.5 seconds at 131 mph.
“Why Go Big, When You Can Go Bigger?” – Size Matters. To reach that power (which is up from 650 bhp / 650 lb-ft) the supercharger itself needed to be bigger since the output of a positive displacement supercharger is proportionate to its size. The Callaway GenThree supercharger is 32% larger in displacement (2300cc vs 1740cc).
The year 1957 was a watershed one for Corvette. After a transformational season of racing and development that saw Corvette come into its own as a high-performance sports car on the international stage, sales climbed from 3,467 in 1956 to 6,339.

In the early-1950s, a team of GM engineers, headed up by Harley Earl, went to work trying to create a fiberglass-bodied car that had the appeal to compete with European sports cars. Harley Earl had excelled at swooping design since the 1920s and designed
This multiple award-winning 1957 Chevrolet Corvette is one of the first production Corvettes fitted with Rochester fuel injection, making it a player in one of the most interesting chapters in Corvette history. As the 1957 model year loomed, newly promoted GM vice president and Chevrolet general manager Ed Cole was not happy.
Perhaps in another dimension, this car could have existed on the original GM Motorama circuit. The thought of ‘prototype show car’ quickly comes to mind when first viewing this 1965 Corvette convertible, finished in rich Silver with Black accents. In keeping with the old-school custom ideas, it features shaved door handles, shaved head-lamp covers, and stack-style injection. However, the way-back machine accelerates right back into the 21st century when the details of this special performance car are unveiled. Created during a two-year, professional body-off restoration, it blends the past to the present.

Craftspeople and technicians at the General Motors Design Center are painstakingly restoring the historic 1 millionth Chevrolet Corvette damaged nearly 16 months ago when a sinkhole opened beneath the National Corvette Museum in Bowling Green, Ky.
The restoration crew is part of GM’s Mechanical Assembly group at the Design Center, which typically spends its time building prototype and concept vehicles.
