Does the Camaro LT1 have cylinder deactivation?
Yes, the Chevrolet Camaro LT1 model does feature cylinder deactivation technology. This fuel-saving feature allows the engine to temporarily shut off some of its cylinders under certain driving conditions to improve fuel efficiency.
What is Cylinder Deactivation?
Cylinder deactivation, also known as displacement on demand or variable displacement, is a technology used in some internal combustion engines to improve fuel economy. It works by temporarily disabling some of the engine's cylinders when they are not needed, such as during light-load driving conditions. This reduces the engine's overall displacement and power output, leading to better fuel efficiency.
Camaro LT1 Cylinder Deactivation
The Chevrolet Camaro LT1 is equipped with a 6.2-liter V8 engine that utilizes cylinder deactivation technology. Under certain driving conditions, such as steady-state cruising, the engine can seamlessly shut off four of its eight cylinders to operate in a more fuel-efficient V4 mode.
When the driver demands more power, such as during acceleration or hill climbing, the engine automatically reactivates all eight cylinders to provide the full power output. This transition between four and eight cylinders is virtually imperceptible to the driver, providing the benefits of improved fuel economy without compromising performance.
Benefits of Cylinder Deactivation
- Improved Fuel Efficiency: By reducing the engine's displacement and power output during light-load driving, cylinder deactivation can improve fuel economy by up to 5-7% in some applications.
- Reduced Emissions: With fewer cylinders firing, the engine produces fewer emissions during cylinder deactivation mode, contributing to lower overall vehicle emissions.
- Seamless Performance: The transition between four and eight cylinders is designed to be imperceptible to the driver, maintaining a smooth and responsive driving experience.
Overall, the inclusion of cylinder deactivation technology in the Chevrolet Camaro LT1 engine is a key feature that helps improve the vehicle's fuel efficiency without compromising its performance capabilities.
How do I know if my Camaro has an AFM?
Engine Cover Markings — Many GM engines equipped with AFM will have a label or badge on the engine cover indicating “AFM” or “Active Fuel Management.”
Is LT1 better than SS?
Even though both the LT1 and SS trims have V8 power, the SS version generally has a lot more tuning geared toward handling, suspension, and performance. There're also notable differences in styling on the exterior, whereby the SS has a rear spoiler and darkened tail lights.
Is the LT1 a bad engine?
The LT1 is a solid engine, with horsepower and torque to spare, and a large aftermarket for performance upgrades. By fixing this one issue, it should be set for many more years of trouble-free driving.
Does LT1 have an AFM?
The LT1 engines are all-aluminum and use Active Fuel Management (AFM) and Variable Valve Timing (VVT). The engines also use direct fuel injection technology, which shoots fuel directly into the combustion chamber instead of the intake runner.

Is LT1 better than LS?
Despite its additional power advantages, at 5.7L (350 cubic inches) in the LT1, it actually has a bigger engine capacity than the 5.665L (345.7 cubic inch) LS1. LS1's feature a 6-bolt main, with LT1 featuring either 2 or 4-bolt. This refers to the total number of bolts that attach the main bearing caps to the block.
Can you turn off cylinder deactivation?
Unfortunately, optimizing the system requires that we adjust the triggers that make us step from all cylinders to shut-off mode and back again. Looking at popular aftermarket tuning software options, there are several ways to disable the system, based on rpm, VSS, gear, voltage, run time, and more.
Does LT1 have cylinder deactivation?
Active Fuel Management: Active Fuel Management temporarily deactivates four of the cylinders and seamlessly reactivates them when the driver demands full power.
