The 2013 Chevrolet Camaro ZL1 produces a factory-rated 580 horsepower at 6,000 rpm and 556 lb-ft of torque at 4,200 rpm. This power is generated by a 6.2-liter supercharged LSA V8 engine, making it the most powerful production Camaro available at the time of its release in the United States.
Engineering the LSA: The Source of 580 Horsepower
To understand the 580 horsepower output of the 2013 Chevrolet Camaro ZL1, one must look at the specific engineering of the LSA engine. The LSA is a 6.2-liter (376 cubic inch) V8 engine based on the GM small-block architecture. While it shares DNA with the LS9 found in the Corvette ZR1, the LSA was specifically tuned to provide a balance of brute force and refinement suitable for a heavy pony car.
The primary driver of this horsepower is the 1.9-liter Eaton TVS (Twin Vortices Series) supercharger. Unlike older Roots-style blowers, the TVS uses a four-lobe rotor design with a 160-degree twist. This design improves airflow efficiency, reduces noise, and significantly minimizes heat soak—a common enemy of sustained horsepower. The supercharger generates approximately 9 psi of boost, forcing dense, pressurized air into the cylinders to facilitate a massive combustion event.
To ensure the engine could withstand the stresses of nearly 600 horsepower, Chevrolet utilized several high-strength components:
- Cast Aluminum Block: Features six-bolt, cross-bolted main bearing caps for maximum bottom-end rigidity.
- Hypereutectic Pistons: Designed with an oil-spray cooling system that directs a stream of engine oil to the underside of each piston, reducing operating temperatures.
- Rotocast A356T6 Aluminum Cylinder Heads: This specialized casting process ensures high strength and excellent thermal conductivity, vital for managing the heat generated by a supercharged V8.
- Forged Steel Crankshaft: Provides a robust foundation for the rotating assembly, ensuring durability under high torque loads.
Drivetrain Efficiency and Power Delivery
Horsepower at the crankshaft is only one part of the equation; how that power reaches the pavement in the United States' varied driving conditions is equally critical. For the 2013 model year, Chevrolet offered two distinct transmission options, both designed to handle the 556 lb-ft of torque.
Tremec MG9 6-Speed Manual
The manual transmission in the ZL1 is a heavy-duty version of the Tremec TR-6060. Designated as the MG9, it features a strengthened output shaft, a high-capacity dual-mass flywheel, and a twin-disc clutch. This setup allows for smoother engagement while handling the massive torque loads. The gear ratios were specifically chosen to take advantage of the LSA’s broad power band, ensuring the car remains in the "sweet spot" of its 580 horsepower curve during aggressive driving.
Hydra-Matic 6L90 6-Speed Automatic
For those preferring an automatic, the 6L90 transmission was employed. This was not a standard Camaro automatic; it was reinforced with additional clutch plates and a strengthened input gearset. One of the most significant features of this transmission is its Performance Algorithm Shifting (PAS), which detects aggressive driving and holds gears longer to prevent unnecessary upshifts. This ensures that the full 580 horsepower is always available on tap.
Power to the Ground
The ZL1 features a high-performance 8.9-inch rear differential housed in a cast-iron case to dissipate heat. To prevent "wheel hop"—a common issue in high-horsepower rear-wheel-drive cars—the ZL1 utilizes asymmetrical half-shafts (a 60mm solid shaft on the right and a 33mm hollow shaft on the left). This unequal stiffness cancels out the oscillations that lead to traction loss, allowing the car to put its horsepower down efficiently.
Performance Metrics and Real-World Testing
In the context of the 2013 automotive landscape, the ZL1's 580 horsepower translated into world-class performance figures. In independent testing conducted in the United States, the ZL1 consistently demonstrated its capability as a "track-capable" car rather than just a straight-line drag racer.
- 0-60 MPH: The ZL1 can sprint to 60 mph in approximately 3.9 seconds with the automatic transmission and 4.0 seconds with the manual.
- Quarter-Mile: It completes the quarter-mile in roughly 12.0 to 12.1 seconds at a trap speed of 119 mph.
- Top Speed: The coupe version is aerodynamically limited to 184 mph, while the convertible reaches a still-impressive 155 mph.
- Nürburgring Lap Time: Proving its handling prowess, the ZL1 clocked a 7:41.27 lap time at the Nürburgring Nordschleife, outperforming many European exotics of the era.
A critical component in managing this power is the Magnetic Ride Control (MRC) 3.0. This suspension system uses magneto-rheological fluid to adjust damping rates up to 1,000 times per second. It allows the ZL1 to remain composed during high-speed cornering where 580 horsepower might otherwise overwhelm a standard chassis.

Comparative Analysis: ZL1 vs. The Competition in 2013
When the 2013 ZL1 was released, its primary rival in the United States was the Ford Shelby GT500. On paper, the 2013 GT500 boasted a higher horsepower figure of 662 hp. However, horsepower is only one metric of performance.
The ZL1 was often praised by automotive journalists for being the more "complete" driver's car. While the GT500 struggled to put its 662 horsepower to the ground due to its live rear axle, the ZL1’s independent rear suspension (IRS) and Magnetic Ride Control provided superior stability and confidence. The ZL1’s Power Traction Management (PTM) system—borrowed from the Corvette ZR1—offered five different modes to help drivers of all skill levels manage the 580 horsepower effectively, ranging from "Wet" mode to "Race" mode.
Furthermore, the ZL1 included significant cooling upgrades that were often optional or less robust on competitors. It featured a dedicated liquid-to-air intercooler, a high-capacity engine oil cooler, and a rear differential cooler as standard equipment, ensuring the 580 horsepower didn't fade during extended track sessions.
Ownership and Maintenance in 2026
As of 2026, the 2013 Chevrolet Camaro ZL1 has entered the "modern classic" phase. For owners or prospective buyers in the United States, maintaining that 580 horsepower requires adherence to specific service intervals.
Engine Health and Supercharger Maintenance
The LSA engine is remarkably durable, but the supercharger isolator is a known wear item. In early models, the isolator could develop a "clatter" at idle. Many owners have replaced this with a solid isolator to ensure long-term reliability. Additionally, the intercooler system should be checked for leaks or pump failure to prevent "heat soak," which can drastically reduce horsepower during spirited driving.
Fuel and Fluids
To maintain the factory-rated 580 horsepower, the LSA requires high-quality 91 or 93 octane fuel. Lower octane fuel will trigger the Knock Sensors, causing the ECU to retard timing and significantly reduce power output to protect the engine. Regular oil changes using a high-quality synthetic oil (meeting dexos2™ standards) are mandatory to protect the supercharger bearings and high-stress internal components.
Modern Tuning Potential
In the 2026 enthusiast market, the 580 horsepower figure is often seen as a starting point. Due to the robust nature of the LSA, "bolt-on" modifications such as a smaller supercharger pulley, upgraded intake, and a custom tune can easily push the ZL1 to 650-700 horsepower without internal engine modifications. However, buyers should be cautious of excessively modified examples that may have been subjected to improper tuning or extreme track use.
