Turbocharged Engines Dominate in 2025 – EPA
The future of automotive engineering is being driven by turbocharged engines, according to an EPA official. By 2025, when the new CAFE standards take full effect, it's predicted that 90% of vehicles on the road will be equipped with this technology. The question arises: **Could every new Toyota model soon come with a turbocharged engine?**
*If the EPA is correct, all these Toyota models could eventually feature turbocharged engines. Is this a realistic future or just a bold prediction?*
At the SAE World Congress, WardsAuto spoke with Edward Nam, director of the EPA’s Light Duty Vehicles & Small Engines Center in Ann Arbor, MI. He explained that current turbochargers are typically limited to around 261 psi (18 bar) of brake mean effective pressure. However, he expects 348-psi (24-bar) units to hit the market by 2016 and become widespread by 2025.
Nam emphasized that turbochargers will continue to evolve, making engines more efficient and capable of meeting stricter fuel economy and emissions standards. Alongside improved transmissions, low-rolling-resistance tires, and better aerodynamics, turbocharging will play a key role in helping vehicles achieve the 54.5 MPG target.
“We believe most automakers can meet the standards through advancements in internal combustion engines and emission controls,†Nam said. “There are many technologies available to help reach those goals.â€
He also noted that turbocharged engines will allow for fewer cylinders without sacrificing performance. For example, trucks like the Ford F-150 or Chevrolet Silverado might soon run on four-cylinder engines, thanks to turbocharging.
While many manufacturers, including Toyota, have invested heavily in various technologies—such as electric vehicles, plug-in hybrids, and diesel engines—Nam estimates that only about 3% of the market will consist of fully electric or plug-in hybrid vehicles by 2025. Diesels and other hybrid options will have smaller shares but won’t dominate.
However, not everyone is convinced. Critics, including Consumer Reports, argue that real-world performance doesn’t always match EPA estimates. Some carmakers, like Toyota, use real-world fuel economy data rather than relying solely on EPA numbers.
Despite the skepticism, the EPA claims that widespread adoption of turbocharged engines could save 4 billion barrels of oil and reduce greenhouse gas emissions by 2.2 billion tons between 2017 and 2025. This could translate into lifetime fuel savings of $5,700 to $7,400 for the average driver, assuming a gas price of $3.87 per gallon.
Of course, these benefits come at a cost. Vehicles sold in 2025 are expected to be $1,800 more expensive than those from 2016. With higher upfront costs and longer payback periods, consumers may need to keep their cars longer to see real savings.
So, the big question remains: **Do you think turbocharged engines are truly the future of automotive technology?** Share your thoughts below.
