The 2017 Chevrolet Corvette is a two-seat sport coupe or convertible that is available in base Stingray, Stingray Z51 or Z06 trim, with the Grand Sport joining the lineup this year as essentially a mashup of the Stingray Z51 and the Z06. The coupe features a removable roof panel that stows in the trunk, while the convertible has a power soft top that can be operated while the car is moving at up to 30 mph. The Stingray, Z51 and Grand Sport are split into 1LT, 2LT and 3LT sub-trims; the Z06 comes in 1LZ, 2LZ and 3LZ sub-trims.
Standard features for the Stingray 1LT include 18-inch front and 19-inch rear wheels with summer tires, Brembo brakes, xenon headlights, LED running lights, heated mirrors, keyless ignition and entry, dual-zone automatic climate control, cruise control, leather upholstery, eight-way power front seats and a power-adjustable steering wheel. You also get OnStar (with a 4G LTE data connection and Wi-Fi hot spot capability), Bluetooth, a color driver information display, an 8-inch central touchscreen with Chevy's MyLink infotainment interface, a rearview camera, Apple CarPlay/Android Auto and a nine-speaker Bose sound system with two USB ports, an auxiliary audio jack, an SD card reader and satellite radio.
The Stingray Z51 1LT adds 19-inch front and 20-inch rear wheels, exterior aero trim, larger front brakes, slotted brake rotors, sportier suspension tuning, revised transmission gear ratios for snappier responses (manual only), an electronic limited-slip differential, a differential cooler, dry-sump oiling for the V8 engine and a dual-mode performance exhaust (optional on non-Z51 Stingrays).
All Stingray 2LT models come with front-view parking cameras, auto-dimming driver side and rearview mirrors, a head-up display, a cargo shade (coupe only), interior-color console and armrest trim, heated and ventilated seats with power lumbar and side-bolster adjustments, driver memory settings and a 10-speaker Bose sound system with enhanced bass response.
The Stingray 3LT models add premium leather upholstery with extended surface coverage, synthetic-suede upper interior trim, an interior-color instrument panel and a navigation system (optional on 1LT and 2LT) that includes the Corvette's unique performance data recorder.
Both the standard and Z51 trims can optionally be equipped with adaptive suspension dampers that are bundled with an upgraded traction management system for Z51 duty.
The Z06 1LZ starts with the Stingray Z51 1LT's standard equipment and adds the supercharged engine, a Z06-specific sport-tuned suspension, larger brakes all around, wider tires, a carbon-fiber hood, a more aggressive aero package (including wider front and rear fenders, expanded cooling vents, and a unique front grille and rear fascia) and the head-up display.
The Z06 2LZ gets the 2LT's upgrades minus the head-up display (already standard), while the Z06 3LZ gets the 3LT's upgrades.
Z06 options include the Carbon-Flash Painted Ground Effects package and the Visible Carbon-Fiber Ground Effects package, both of which add an enhanced front splitter and rocker panels along with a larger rear spoiler with a fixed "wickerbill" vertical extension at the back. The upgraded front splitter and rocker panels are also included in the Z07 Performance package (albeit with larger end plates for the splitter), which adds an adjustable, see-through center section to the rear spoiler (for fine-tuned track performance), special tires, carbon-ceramic brake rotors and the adaptive dampers.
The new Grand Sport largely mirrors the Stingray Z51 in terms of feature content, but it adds a slew of performance hand-me-downs from the Z06, including the upgraded cooling system, wider fenders and tires, adaptive dampers, upgraded suspension components and bigger brakes (though not as big as the Z06's). There are also subtle differences between the graphics, trim and rear wing of the Grand Sport and Z06. Note that the Grand Sport is eligible for a Z07 package of its own with similar content.
