New Report Investigates Myths About EV Particulate Pollutants

A new report by the motoring company RAC disputes the claims that electric vehicle tires and brakes create more particulates than those of gas cars. The company commissioned battery electrochemist Dr. Euan McTurk to address the negative myths of electric vehicles specifically on emissions generated from tire and brake wear. According to Simon Williams, the company’s EV spokesperson, RAC hopes that positive real-life experiences will clear up the confusion surrounding EVs.

The report, released on Friday, investigates the levels of toxic particulate matter known as PM 2.5s, which are said to be worse in comparison to emissions from ICE vehicles. This is because during driving it is believed that the additional weight of the battery increases wear and tear of the tires and brakes. Last year while being quizzed by MPs on pollution, George Eustice, the environment secretary, said that “EVs may not be as green,” and it remains uncertain the tear and wear effect these vehicles will have on the roads.

Findings from the report reveal that EV brakes wear at a slower rate in comparison to internal-combustion engine vehicles. This is because electric cars use regenerative braking. This is where the motor operates in reverse to charge the battery, and in turn, the car slows down without the brakes being used.

McTurk found that brake pads from 11 Nissan Leaf taxis operating under Dundee Taxi Rentals had a lifespan of more than 100,000 miles.  This is four times longer in comparison to the conventional cars. The reason is because discs are usually changed from warping and do not wear. As a result, they last twice as long as gas taxis.

One of the best-known electric car mechanics in the United Kingdom supports the claim. According to Cleevely EV, it is regular for EVs that have brakes which have covered more than 100,000 miles. The Cheltenham-based company states that brake replacements normally happen as a result of seizing up from lack of use.

The report also revealed that the wearing off of tires was considered to be less of an issue. Additionally, the weight of an electric vehicle is not the contributing factor to tire replacements. According to Dundee Taxi Rentals, the lifespan of the front tires on the Nissan Leaf is between 5,000 and 10,000 miles less than ICE vehicles. Meanwhile, the rear tires have a lifespan of between 30,000 and 36,000 miles.

According to Turk, tire companies are creating tires for electric vehicles that provide efficiency and less wear with the same grip. Companies such as Enso have been established to take on tire pollution.

Now that research is backing the belief that electric vehicles are indeed good for the environment, it is likely that many who were still sitting on the fence will consider purchasing an EV from companies such as Lordstown Motors Corp. (NASDAQ: RIDE) in order to contribute to fighting climate change.
