Toyota is set to introduce next-generation hybrid and regular gas engine choices by Spring 2018.

The shift, part of the automaker’s five-year plan to developer cleaner and sportier engines, will start with its new 2.0-liter Dynamic Force gasoline engine. According to Toyota, it delivers an 18-percent improvement in fuel economy and acceleration with a CVT transmission, versus 9-percent fuel economy and 17-percent speed improvement when paired on hybrids, respectively.

Tabbed as its first recipient is the redesigned Auris hatchback.

“Developing the most fuel-efficient powertrains using petrol engines and hybrid systems will be the best way to have an impact (on reducing emissions), and we remain committed to this,” said Mitsumasa Yamagata, chief engineer at Toyota’s powertrain product planning division, in a briefing. “At the same time, we will be able to use the technology developed for these powertrains in EVs and FCVs,” he added.

Toyota has also accelerated its electric vehicle powertrain efforts, promising to deliver ten EV models and half of its models to become electrified by early 2020.

Supporting these new powertrains is a new building platform called the Toyota New Global Architecture. This concept comprises of a modular platform that shares parts, processes, and components between vehicles, such as drivetrain and driver seating position. Some improvements brought on by the platform include a lower center of gravity for improved handling and improved EPA numbers.

Also, the new framework is expected to reduce production costs. Toyota is aiming to introduce TNGA in 80-percent of vehicles sold in Japan, U.S., Europa, and China by 2023.
