The Chevrolet SS 6.2 V8 Automatic, produced for the 2014 to 2016 model years, represented Chevrolet’s final rear-wheel-drive performance sedan in the American market for a considerable period. Positioned as a direct descendant of the Pontiac G8 GXP, the SS aimed to deliver a blend of American muscle and Australian engineering – a result of its production at Holden’s Elizabeth plant in South Australia. This variant, equipped with the 6.2-liter LS3 V8 and a six-speed automatic transmission, served as the flagship model within the SS lineup, offering a significant performance upgrade over potential future, smaller-engined options that were never realized. It was Chevrolet’s answer to performance sedans like the Dodge Charger SRT and the Ford Taurus SHO, though it distinguished itself with a more focused driving experience.

Powertrain & Engine Architecture
At the heart of the SS was the 6.2-liter LS3 V8 engine. This naturally aspirated powerplant, a member of General Motors’ Small-Block family, featured aluminum cylinder heads, a cast iron block, and direct fuel injection. The LS3 produced 415 horsepower at 5900 rpm and 415 lb-ft of torque at 4600 rpm. The engine’s architecture was relatively simple, prioritizing reliability and readily available parts. The six-speed 6L80 automatic transmission was chosen for its durability and ability to handle the engine’s output. While a manual transmission was available in other Holden-produced models, it was not offered in the US-market Chevrolet SS. The transmission featured paddle shifters for manual control, but was primarily geared towards smooth, comfortable shifts.
Driving Characteristics
The SS 6.2L Automatic delivered brisk acceleration, achieving 0-60 mph times in the low-to-mid 5-second range. The automatic transmission, while not as engaging as a manual, provided quick and seamless gear changes. The torque converter allowed for smooth launches, and the transmission’s programming was tuned for a balance between performance and fuel efficiency. Compared to a hypothetical manual version, the automatic offered slightly slower acceleration but greater ease of use in everyday driving. The rear-wheel-drive layout contributed to a balanced feel, although traction could be a concern under hard acceleration, particularly with the generous torque output. The suspension was tuned for a comfortable ride, but also provided good body control during cornering.
Equipment & Trim Levels
The Chevrolet SS came standard with a relatively comprehensive list of features. Interior appointments included leather upholstery, heated and ventilated front seats, a dual-zone automatic climate control system, and an 8-inch touchscreen infotainment system with Chevrolet’s MyLink interface. Standard safety features included a rearview camera, parking sensors, and a suite of airbags. Optional extras included a Bose premium sound system, a sunroof, and a head-up display. The SS trim represented the highest level of equipment available, with no further upgrade paths offered by Chevrolet.
Chassis & Braking
The SS utilized a robust chassis derived from the Holden Commodore platform. The suspension consisted of an independent multi-link setup at both the front and rear, providing a comfortable ride and good handling characteristics. The braking system featured four-wheel disc brakes with Brembo calipers at the front, providing ample stopping power. ABS (Anti-lock Braking System) was standard. The SS’s weight distribution was nearly 50/50, contributing to its balanced handling. The rear suspension geometry was optimized for performance, minimizing body roll during cornering.
Market Reception & Comparison
The Chevrolet SS was generally well-received by automotive critics. Praise was given for its powerful engine, comfortable ride, and spacious interior. However, some reviewers noted that the automatic transmission lacked the engagement of a manual gearbox. Fuel economy, at 17 mpg combined, was considered reasonable for a V8-powered performance sedan, but not exceptional. Compared to the Dodge Charger SRT, the SS offered a more refined driving experience and a more upscale interior. Against the Ford Taurus SHO, the SS provided a more engaging driving experience and a more powerful engine. The SS’s relatively high price point, however, limited its appeal to a niche market.
Legacy
The Chevrolet SS represents a unique chapter in Chevrolet’s history. As the last rear-wheel-drive performance sedan offered by the brand for a significant period, it has gained a following among enthusiasts. The LS3 engine is known for its reliability and tunability, making the SS a popular platform for modifications. On the used car market, well-maintained examples of the SS 6.2L Automatic command a premium price. The powertrain, while not without its quirks, has proven to be durable and long-lasting, ensuring that the SS will remain a desirable performance car for years to come. The discontinuation of the SS marked the end of an era for American rear-wheel-drive sedans, leaving a void that has yet to be fully filled.
