How much horsepower does the Chevy SS Holden have?
The Chevy SS Holden has 415 horsepower.
In more detail, the U.S.-market Chevrolet SS is based on Holden's VF Commodore SS and is powered by a 6.2-liter LT1 V8 tuned to deliver 415 horsepower and 415 lb-ft of torque, paired with a six-speed automatic transmission and rear-wheel drive. This model represents GM's efforts to bring a performance sedan with Holden roots to the North American market.
Power output and drivetrain basics
The following figures summarize the engine output and driving configuration of the Chevy SS:
- Engine: 6.2-liter LT1 V8
- Horsepower: 415 hp (309 kW) at approximately 5900 rpm
- Torque: 415 lb-ft (563 Nm) at approximately 4600 rpm
- Transmission: 6-speed automatic (6L80) with manual shift mode
- Drive: Rear-wheel drive
These numbers reflect the official specifications for the U.S.-market Chevy SS during its 2014–2017 production run. For context, the related Camaro SS variant (sharing the same engine family) targets around 455 hp, while the Chevy SS is tuned to a different balance suitable for a sedan platform.
Background and Holden heritage
The Chevy SS is built on Holden's VF Commodore platform and was sold in the United States as a performance sedan from 2014 to 2017, before GM discontinued the model. The vehicle stands as a notable example of GM's global engineering collaboration, rebranding an Australian-built sedan for the North American market.
Engineering lineage
Powering the Chevy SS is a member of GM's long-running small-block V8 family, adapted for the SS configuration and mated to a 6L80 automatic transmission to deliver a balanced, rear-drive driving experience tied to Holden’s chassis philosophy.
Summary
In brief, the Chevy SS Holden is rated at 415 horsepower from a 6.2-liter LT1 V8. This setup provides solid performance in a sedan package and reflects GM’s international engineering approach during the model’s brief 2014–2017 run.
How much horsepower does a Chevy SS holden have?
The Chevy SS (Holden-based) sedan came standard with a 6.2-liter V8 engine that produced 415 horsepower and 415 lb-ft of torque. While 415 hp is the factory output, some owners have significantly increased the horsepower through modifications like superchargers or turbochargers.

How much HP does a 454 SS make?
The "454 SS" refers to the 1990-1993 Chevrolet 454 SS pickup truck, which had a 7.4-liter (454 cubic inch) V8 engine that produced 230 horsepower and 385 lb-ft of torque in its initial 1990 model year. Horsepower was sometimes listed slightly higher in later years, with some sources citing a range of 230-255 hp for the production run.
- Engine: 7.4-liter (454 cubic inch) V8
- 1990 Model: 230 hp and 385 lb-ft of torque
- Later Models (1991-1993): Some sources list the horsepower in a range of 230–255 hp, while torque remained around 385 lb-ft.
- Reason for lower horsepower: The horsepower was modest for its size due to emissions regulations and tuning of the era.
- Torque: The truck's strength was its significant torque, which provided a powerful "feel" even with the lower horsepower rating.
What is the Holden version of the Chevy SS?
Holden Commodore /
The Holden Commodore / Chevy SS was built on the GM Zeta platform and came in a front-engine, RWD layout. Body styles offered for the Holden Commodore included a two-door coupe, a four-door sedan, and a five-door station wagon.
Why are Chevy SS so rare?
Chevy SS sedans are rare because they were only produced for a short four-year run (2014–2017) with low production numbers, partly due to a lack of marketing and poor sales figures that were only about 3,000 per year. The car was imported from Australia as a Holden Commodore and its production was ultimately limited by the closure of the Holden plant, according to Quora.

- Limited production: The car was only produced for four model years, ending after 2017, which inherently limits the total number of vehicles available.
- Low sales and poor marketing: Despite being a high-performance sedan with a V8 engine, sales were lackluster, partly because Chevrolet did not heavily market the car.
- Imported from Australia: The Chevy SS was an imported Holden Commodore, and its production run was tied to the Australian Holden plant, which GM later shuttered.
- Short lifespan: The vehicle was essentially a stop-gap model to honor a prior deal to import sedans from Holden after the Pontiac G8 was canceled, and there was no plan for a long-term replacement.
