The Z51 performance package is also a must-have as it brings all the best performance-oriented gear to the table. Performance-tuned suspension with threaded spring seats to adjust dampers, bigger brakes, additional cooling, a unique axle ratio, and a performance exhaust.

Airflow-enhancing model-specific front and rear fascias, a center-mounted quad-tipped exhaust system, a 3.6-inch wider body to accommodate larger tires and side air intakes, standard reconfigurable rear spoiler, front 20-inch and rear 21-inch wheels in a Z06-specific design, available carbon-fiber trim for the interior, steering wheel, and paddle shifters.
The E-Ray hybrid electric model adds an electric motor to the front wheels which increases the power to 655 horsepower. Chevrolet claims the E-Ray can reach 0-60 in 2.5 seconds and can achieve a quarter mile in 10.5 seconds. The Stealth Mode allows the driver to make a quiet entrance using only electric power for 3-4 miles at speeds of up to 45 mph.
