2016 Toyota Prius Engine Garners 40% Thermal Efficiency

Could the Prius be any more efficient? Well, according to Toyota, it can!

Recently announced at the Annual Spring Congress for Japan’s Society of Automotive Engineers, the 2016 Toyota Prius engine will boast 40% thermal efficiency, an increase of 1.5% over its previous model, making it the most efficient Prius to date. Early estimates speculate that the new Prius will be able to offer 60 mpg.

“The efficiency will be realized by improving the EGR (exhaust gas recirculation) limit from 21 percent (current model) to 28 percent,” reports Nikkei Technology Online. “The thermal efficiency of 40 percent would be the world’s highest for a mass-produced gasoline engine.”

So just how was Toyota able to improve its thermal efficiency? According to the Japanese automaker, the increased thermal efficiency came from adjusting the intake port, recirculating more exhaust gases, and remodeling the shape of the piston.

The 2016 Toyota Prius is expected to be unveiled to the public this fall and will hit showrooms early next year. Until then, be sure to come visit our lineup of fuel-efficient vehicles at Bill Walsh Toyota today!
