Hybrid powertrains have long been Toyota’s primary solution to boost fuel economy across their product range, but even that may not be enough to meet stricter CAFE regulations. In order to meet the mandated 39 MPG average fuel economy required of automobiles by 2016, Toyota has announced their intention to incorporate smaller, turbocharged engines and direct fuel injection into their product lines over the next five years.
Left Lane News quotes Takeshi Uchiyamada, Toyota’s head of R&D, as saying:
“In the next five years, the general trend is downsizing of engines and the use of turbochargers. Another development will be direct fuel injection… eventually, we will see significant numbers of vehicles carrying engines with turbochargers.”
Uchiyamada indicated that the Camry and the Corolla would be the two likeliest platforms to receive turbocharged engines, as both sell in significant quantities to have a major impact on the brand’s CAFE. Long term, Toyota expects no more than 20% of vehicles sold to be hybrids, even as late as 2020. Offering more fuel efficient internal combustion engines ensures that Toyota will have product suitable for those not willing to embrace hybrid drive systems.
