Discover When GM First Utilized AFM Technology in Vehicles.

Published by Dustin Babich on

Gm started using active fuel management (afm) in 2005 for select v8 engines. It allows engines to switch between 8 and 4 cylinders to improve fuel efficiency and reduce emissions.

General motors (gm), one of the largest automobile manufacturers in the world, has always been at the forefront of technology and innovation. In 2005, the company introduced active fuel management (afm) in select v8 engines, which allowed the engines to switch between 8 and 4 cylinders.

The technology was aimed at improving fuel efficiency and reducing emissions. Since then, afm has become a standard feature on many of gm’s vehicles. In this article, we will discuss what afm is, how it works, and its benefits and drawbacks. So, if you’re curious about gm’s active fuel management technology and its impact on the automotive industry, keep reading.

The Evolution Of Gm’S Engine Technology

Gm has a long and illustrious history of engine technology advancements. The company has always been at the forefront of innovation in this area. Their engines have evolved considerably over the years, with new features and technologies being introduced with each new model.

The use of afm is one such technology that has become an integral part of gm’s engine technology. It started as early as 2005 in their larger displacement v8 models. Afm (active fuel management) helps optimize fuel efficiency by deactivating cylinders when not needed.

In addition, gm has also introduced other engine technologies such as direct injection, variable valve timing, and cylinder deactivation, among others. All these advancements have made gm engines more efficient, powerful, and durable over the years.

Introduction To Active Fuel Management (Afm)

General motors (gm) started using active fuel management (afm) in 2005 to improve fuel efficiency in their vehicles. The technology deactivates half of the engine cylinders during low-load driving conditions to save fuel. Afm provides many benefits, including increased fuel economy, reduced emissions, and improved engine performance.

Today, afm is a standard feature in many gm vehicles, including the chevrolet silverado and tahoe, gmc sierra and yukon, and cadillac escalade. The market demand for afm has increased due to environmental concerns and rising fuel costs. By implementing afm, gm has established itself as a leader in fuel-efficient vehicle technology, allowing it to meet market demands while adhering to strict environmental regulations.

When Did Gm Start Using Afm In Vehicles?

General motors (gm) began utilizing active fuel management (afm) in vehicles in the mid-2000s. The early development stages of afm can be traced back to 1981, when gm produced a research vehicle that implemented the technology. It wasn’t until 2005, however, that the first gm vehicles with afm were released.

This technology allowed vehicles to achieve improved fuel efficiency, which was necessary for gm to remain competitive with other automotive manufacturers. Among the competitors ‘ technology, ford was using ecoboost engines, where turbochargers and direct injection provide the performance of a larger engine but with better fuel efficiency and lower co2 emissions.

Nevertheless, afm has proven to be a reliable technology that remains popular among many gm vehicle owners today.

Afm In Various Gm Vehicle Models

General motors has been using active fuel management (afm) technology in various vehicle models for several years. Some of the gm models that use afm include the chevrolet silverado, gmc sierra, and cadillac escalade. Afm technology is designed to improve fuel efficiency and reduce emissions by shutting down half of the engine’s cylinders during light-load driving conditions.

With the introduction of afm technology, gm took a big step forward in fuel efficiency and eco-friendliness. Despite its many benefits, afm technology can have its issues in vehicles that are not equipped for it, such as excessive oil consumption and lifter failure.

Before purchasing a gm model with afm, consumers should be aware of the pros and cons of this innovative technology.
