For a high-performance sports car whose main competitors are the Porsche 911 and the Nissan GT-R, the Chevrolet Corvette has been in need of a few package enhancements. Specifically, Chevrolet has finally upgraded the interior with a new steering wheel and seat design. The seats now offer more supportive bolstering along the sides with optional microfiber inserts. The new steering wheel now has high-wrapped spokes and "streamlined" switch trim, according to GM.

There's also a new padded center console and armrests. In the past, the lack of supportive seats and a plain-looking steering wheel were two major areas of customer complaints, and Chevrolet has rightly fixed those wrongs. A new Bose nine-speaker premium audio system, Bluetooth, and a head-up display round out the upgrades. Additionally, the Z06 and ZR1 now offer optional Michelin Pilot Sport Cup Zero Pressure tires that are supposedly good for an eight-percent gain in lateral acceleration.

The Z06 also receives options such as traction control, a full-width rear spoiler, and a carbon fiber hood. Meanwhile, the top-of-the-line ZR1 receives transmission adjustments in fifth and sixth gear that improves fuel economy. Finally, there are new brake caliper colors (red, yellow, silver, or grey) for all models for further customer personalization.
