The Grand Sport represented one of the most balanced expressions of the C6-generation Corvette, combining the widebody presence of the Z06 platform with the more approachable naturally aspirated LS3 powertrain. Designed as a track capable street car, the Grand Sport delivered exceptional braking, handling, and everyday usability while maintaining the unmistakable visual stance that defined modern Corvette performance.
This example has been professionally upgraded with the HPE700 performance package from Hennessey Performance Engineering, a Texas-based builder known for transforming production sports cars into high horsepower machines through carefully engineered forced induction and calibration work.
The HPE700 package centers around a TVS2300 supercharger system working in concert with high flow cylinder heads, an HPE performance camshaft, long tube headers, and optimized engine management calibration. Additional upgrades including high flow induction components, injector and Boost-A-Pump enhancements, and a low temperature 160 degree thermostat were installed to support sustained performance under load.
Factory displacement remains the original 6.2 liter LS3 V8 architecture, now enhanced to produce approximately 700 horsepower through professionally integrated forced induction. The result is a Grand Sport that retains drivability while delivering supercar level acceleration and dramatic throttle response.
Power is transferred through a 6-speed manual transmission, preserving the mechanical engagement that enthusiasts associate with the C6 platform. The Grand Sport chassis provides widebody aerodynamics, upgraded braking hardware, and suspension tuning that allows the car to remain composed during aggressive driving.
This particular car shows only 9,570 miles, preserving the condition and character of the build. Lightweight Apex performance wheels enhance visual presence while complementing the performance intent of the package.
Hennessey performance builds from this era have become increasingly desirable among collectors who appreciate period correct tuner craftsmanship paired with American V8 power. The HPE700 represents one of the more celebrated forced induction upgrades available for the LS3 platform and remains highly regarded for its balance of power delivery and reliability when properly maintained.
For the enthusiast seeking a modern American performance car with documented Hennessey engineering, low mileage, and dramatic presence, this Grand Sport HPE700 offers a compelling blend of heritage, speed, and collector appeal.
