Does a 2010 Camaro SS have Active Fuel Management?
No, the 2010 Chevrolet Camaro SS does not have Active Fuel Management (AFM). The Camaro SS of that model year was equipped with a 6.2-liter V8 engine that did not feature the fuel-saving technology of AFM.
Explaining Active Fuel Management
Active Fuel Management, also known as cylinder deactivation, is a technology used in some engines to improve fuel efficiency. It works by temporarily shutting off fuel delivery and spark to some of the engine's cylinders when full power is not needed, such as during cruising or coasting. This reduces the engine's workload and saves fuel. AFM is commonly found in V8 engines, allowing them to operate as a V4 under light load conditions.
The 2010 Camaro SS Engine
The 2010 Chevrolet Camaro SS was powered by a 6.2-liter LS3 V8 engine that produced 426 horsepower and 420 lb-ft of torque. This engine did not have Active Fuel Management capabilities. Instead, it used a traditional fuel delivery system to provide full power to all eight cylinders at all times.
The lack of AFM in the 2010 Camaro SS was likely due to the performance-oriented nature of the vehicle. The SS model was designed to prioritize power and acceleration over fuel efficiency. Chevrolet wanted to ensure the Camaro SS delivered a thrilling driving experience, which the LS3 V8 without AFM was well-suited to provide.
Fuel Economy of the 2010 Camaro SS
Without the fuel-saving benefits of Active Fuel Management, the 2010 Camaro SS had relatively modest fuel economy ratings. The manual transmission model achieved 16 mpg in the city and 24 mpg on the highway, while the automatic transmission version was rated at 15 mpg city and 24 mpg highway.
While the lack of AFM may have impacted the Camaro SS's fuel efficiency, it allowed the vehicle to deliver the powerful, responsive performance that enthusiasts expected from the iconic muscle car.
Which Camaro has an AFM?
problem solved... All 6th gen V8 cars have AFM, on the older 5th gens only the L99/ automatic transmission cars have it.
Which GM engines have active fuel management?
GM engines that have had Active Fuel Management (AFM) include many V6 and V8 engines across different families, such as the GM Small Block Gen IV engine family, first-generation EcoTec3 engine family, and second-generation High-Feature V6 DOHC engine family. Examples include the 5.3L Vortec 5300 V8, the 6.2L L99 V8, and the 4.3L LV3 V6. While AFM is being phased out in favor of Dynamic Fuel Management (DFM) in some newer models, it remains in a number of V8s.
Engine families and examples
- GM Small Block Gen IV: Includes engines like the 5.3L V8 Vortec 5300, 3.9L V6 LZ8, 5.3L V8 LS4, and 6.2L V8 L99.
- First-generation EcoTec3: This includes the 4.3L V6 LV3, 5.3L V8 L83, and 6.2L V8 L86.
- Second-generation High-Feature V6 DOHC: Features the 3.6L V6 LGX (Naturally Aspirated) and the 3.0L V6 LGW (Twin-Turbo).
- First-generation High-Feature V8 DOHC: Includes the 4.2L V8 LTA Twin-Turbo.
How to identify an AFM engine
- Check the VIN and RPO codes: You can look up the specific engine options for your vehicle using its Vehicle Identification Number (VIN) and Regular Production Option (RPO) codes, as explained on this Facebook thread.
- Look for physical indicators: For some older models, the presence of an AFM sticker or the specific design of the valley cover can indicate the system is present, says this Facebook thread.
Important considerations
- AFM vs. DFM: Dynamic Fuel Management (DFM) is GM's more advanced cylinder deactivation technology, which has largely replaced AFM in newer engines.
- Recent changes: Some engines, like the 5.3L V8 L84 and 6.2L V8 L87, have had AFM/DFM removed in favor of other technologies, such as the 2.7L I4 L3B engine, which does not use AFM at all in recent models.
- Microchip shortage impact: Due to global microchip shortages, some 2021 and 2022 models may not have AFM or DFM even if the engine would normally be equipped with it, notes GM Authority.
Does the 2010 Camaro have an AFM?
The L99 was an adapted version of the LS3. It was ONLY available in the 2010-15 Camaro SS with an automatic transmission. It used different pistons, crankshaft, camshaft, and valves. It also added Active Fuel Management (AFM) and Variable Valve Timing (VVT).
Does the LS3 have an AFM?
No, the standard LS3 engine does not have Active Fuel Management (AFM). However, the similar-looking L99 engine, which was used in automatic transmission applications, does have AFM. A key identifier is that the LS3 has a 6.2L displacement and is generally paired with a manual transmission, while the L99 has AFM and a different set of cylinder heads.
- LS3: Does not have AFM or Variable Valve Timing (VVT). It is associated with manual transmissions.
- L99: The automatic transmission version of the engine that has AFM (also known as DOD, or Displacement on Demand).
- Identification:
- LS3 has cylinder head casting number 821.
- L99 has cylinder head casting number 823.
- LS3 uses the RPO code LS3.
- L99 uses the RPO code L99.
