Contrary to popular belief, mass reduction does not automatically equal fuel savings, especially when it comes to urban driving. There are other factors that determine the fuel efficiency of a vehicle such as driving cycle, vehicle size and its powertrain. Until recently, there was a  lack of variety in engine types and powertrains, so even though automakers reduced the weight of car frames, they could not apply a complementary engine or powertrain to the lighter parts.

So, have automakers been lightweighting for nothing?

Of course not, in the past decade alone, engines and powertrains have also become extremely efficient through advancements in start-stop-systems and downsizing, and newer options including hybrids, electric batteries and range extenders that now allow automakers to capitalize on their lightweight materials.

Although there are several lightweight materials, below are 5 reasons why AHSS continues to be the lightweight material of choice for automakers:

1. Decision Makers Care About the Environment

Well, not everyone, but many countries around the world have started the process to phase out gasoline and diesel-fueled cars, including India and China, the two largest automotive markets in the world. Governments are taking serious action against climate change and it will reflect in their policies. Automakers are choosing to lightweight their vehicles for lower emission rates with AHSS, because not only is AHSS lightweight, there are no trade-offs with other vital features such as safety and cost-effectiveness.

2. Everyone’s Going Electric

Globally, automakers are investing in electric vehicles (EVs) in line with national and international environmental policies. However, EVs still have a ways to go before they become the norm. EVs will face the same safety requirements as regular cars, but with the added responsibility of protecting the battery and its flammable components during a crash.

In 2016 there were several car accidents involving the Tesla Model S, where leaked battery fluids caused fires. Automakers need to find a solution to make EVs as safe, and eventually, safer than traditional cars. As an innovative automotive material, AHSS was built for safety.

3. Safety is Always First

Safety is and should always be the number one priority for automakers, material providers and policymakers alike. Even with all the hype about autonomous driving and sensors, there is very little chance that policymakers will reverse the stringent safety regulations in place today. People want to feel safe, no matter what type of car they are getting into.

One possible material solution is Complex Phase (CP) steel, a type of POSCO GIGA STEEL for the vehicle’s side panels, bumper rails and door impact bars- the parts that determine the safety ratings of the vehicle. It has superior strength and shock-absorbing qualities, without the added weight of traditional high-strength materials, and that’s why carmakers such as GM Korea, Ssangyong Motors and Renault Samsung Motors all use POSCO GIGA STEEL.

4. Cost is Always Second

This goes for automakers as well as drivers on the consuming end. Drivers want lower costs without compromising safety and performance ratings, and desire fuel efficiency- a major reason why automakers are lightweighting.

Some automakers choose alternative materials such as aluminum and carbon fiber to meet lightweight requirements to find that not only are the materials more costly over steel, factories need an equipment overhaul to work with them. Moreover, there are additional costs related to training employees to work with new materials, whereas all auto manufacturers are familiar with welding and forming steel.  

Take a look at this infographic and see how AHSS stacks up against other lightweight materials in terms of cost and performance.  

5. It’s Not Over Till It’s Over

No two lightweight materials are the same when observed under the life-cycle approach, a comprehensive life cycle assessment of a material’s automotive carbon emissions from production to disposal. Often times, the process of manufacturing lightweight materials and improved powertrains result in more carbon emissions than they are saving.

At the end of the day, steel has the lowest production-related emissions and can be recycled at the end of its lifecycle. Steel remains the most recycled material because it can be reapplied in different forms almost infinitely.

Automakers are increasingly incorporating lightweight materials to their new models. Although competition for the greatest market share of lightweight materials is fierce, AHSS is by far the leading material when it comes to lightweight solutions. According to McKinsey & Company’s Lightweight, Heavy Impact report, the percentage of high-strength materials used for cars will increase to 38 percent by 2030, compared to 15 percent in 2010. Steel continues to evolve according to the changing demands of the auto market, and for now, there is no other multi-solution material that can compete.

What is an Electric Vehicle?

An electric car is basically an automobile that is powered by electricity. It is powered by an electric motor that runs on a rechargeable battery as opposed to a gasoline engine. Electric vehicles has gained widespread recognition predominantly because it is the environmentally-friendly alternative to gas guzzling automobiles.

Why should you care about Electric Vehicles?

 You might have heard the word ‘electric car’ lately, but might not understand what the direct benefits are. The major reasons that electric cars is top-of-mind for the auto industry and society as whole are for the following reasons:

1)      Less pollution: Electric cars are an eco-friendly alternative to gasoline powered cars as they create less pollution

2)      Cost effective in the long-run: Electric cars run on electricity so you can save up on annual car fuel costs and expensive maintenance related to oil changes, fuel filters, etc.

3)      Reduces fuel dependency: Electric vehicles can be powered by electricity produced from multiple energy sources including wind, solar, hydro, nuclear, biofuel, and fossil fuel sources. Therefore, electric vehicles have the potential to support economies while also reducing dependence on imported oil.

4)      Better Sound Quality: Electric cars may be difficult to differentiate from regular cars from the outside, but electric motors provide quiet and very smooth operation.

Challenges for Electric Vehicles

That is not to say that electric vehicles face no challenges. Driving range is a concern for consumers as gasoline vehicles can go longer distances. Recharge time and overall bulk are concerns also. Companies, including POSCO, are continuously investing time and energy to improve technologies and materials for electric vehicles.
