Toyota eyes turbos, direct injection


Toyota Motor Corp. plans to introduce 11 new or redesigned hybrid vehicles by 2012, but the carmaker is hardly neglecting the humble internal combustion engine.

Takeshi Uchiyamada, executive vice president in charge of r&d, also wants to increase the fleet's fuel efficiency by putting turbochargers and direct fuel injection in smaller vehicles. "In the next five years, the general trend is downsizing of engines and the use of turbochargers," Uchiyamada said in an interview. "Another development will be direct fuel injection."

Turbos and direct fuel injection will be added throughout Toyota's lineup--even in four-cylinder engines and models such as the Corolla and Camry, he said.

"Eventually, we will see significant numbers of vehicles carrying engines with turbochargers," said Uchiyamada, 64, who was chief engineer of the first-generation Prius.

Other changes will include expanded use of idle-stop technology, which saves fuel by turning off the engine when the car comes to a standstill, and advances in variable valve systems.

Toyota will need the new technologies to stay ahead of sharper competition from rivals such as South Korea's Hyundai Motor Co., which is trying to become a green car leader.

Of the 11 upcoming hybrids, four will be model changes of existing hybrids. The other seven will be new models, either stand-alone hybrids or hybrid versions of vehicles that previously didn't have a gasoline-electric option, Uchiyamada said.

He expects Toyota's annual hybrid sales to hit 1 million units by 2015. In 2009, Toyota sold approximately 530,000 hybrids worldwide.

But in the United States, he predicted, hybrids will still only account for between 10 percent and 20 percent of Toyota's sales by 2020.

Report: Toyota plans to add turbo, direct-injection to most of lineup

Toyota has big plans for its model lineup, as the automaker intends to introduce 11 new or redesigned vehicles by 2012. This will be accomplished by offering hybrid versions of existing models, as well as introducing all-new hybrid vehicles. However, Toyota's focus isn't going to be entirely on improving the electric half of the hybrid equation. The automaker is looking at ways to produce more efficient gasoline engines, and turbochargers and direct fuel injection are both in the cards.

There's no word yet on which models will benefit from either technology first, but the initial round of products should also come equipped with start-stop technology in addition to the DI and turbo. It was hard to believe at the time, but maybe a turbocharged, hybrid MR2 really is right around the corner.

Toyota’s green technology has long relied on the use of hybrid systems, but the Japanese automaker will begin to employ turbo charging and direct injection in the coming years as it looks to increase its overall fuel economy.

Following in the footsteps of several other automakers, Toyota is now developing turbocharged and direct injected gasoline engines for its small and mid-size vehicle offerings. The use of turbos and direct injection is intended to boost Toyota’s overall fleet fuel economy.

“In the next five years, the general trend is downsizing of engines and the use of turbochargers,” Takeshi Uchiyamada, head of Toyota’s R&D, said in a recent interview. “Another development will be direct fuel injection.”

Uchiyamada added: “Eventually, we will see significant numbers of vehicles carrying engines with turbochargers.”

Uchiyamada failed to give a timeline for Toyota’s upcoming turbocharged engines, but did indicate the new engines would likely surface in the Corolla and Camry.

Toyota expects that just 10-20% of its new car sales in 2020 will be comprised of hybrid vehicles, so the company’s new turbo and direct injection technology should become a fairly large part of its green initiative.
