The Chevrolet SS is unique in the GM lineup. A rear-wheel-drive sports sedan isn't found elsewhere without upgrading to something in the more up-market Cadillacs. But unlike the Cadillac CTS, the SS gets a powerful V8 engine, standard leather seating, 19-inch wheels, HID headlamps and an integrated navigation with an 8-inch touchscreen display. Standard features on the Chevrolet SS include a 6.2L V8 engine. It makes 415 horsepower and 415 pound-feet of torque. The standard transmission is a 6-speed automatic with TAPshift manual override, while a 6-speed manual is available. Push-button start, a limited-slip differential, sport suspension with Magnetic Ride Control and 4-wheel Brembo disc brakes are standard. The headlamps are HID with automatic dimming, and the wipers are rain-sensing. Navigation comes included with the audio system and is operated through a large 8-inch touchscreen display. SiriusXM satellite radio, a USB port, Bluetooth and nine Bose speakers also come with the audio system. Included with the new OnStar 4G LTE system is Wi-Fi hotspot capability. Leather-trimmed seats are standard. Those seats are heated and ventilated and power-adjustable. An easy-to read heads-up display projects vehicle speed, audio system information, compass and navigation prompts onto the inside of the windshield. Dual-zone climate control and keyless access are also standard. Safety features include park assist, Blind Zone Alert, Cross-Traffic Alert, Forward Collision Alert and Lane Departure Warning. Air bags include dual-stage front, side-impact, knee and curtain side-impact.
