Toyota New Global Architecture Reveals New Engines and Transmissions

Posted Saturday, Dec 31, 2016 by nhtwpprod

The Toyota New Global Architecture (TNGA) recently revealed information about new engines and transmissions the car manufacturer will start incorporating into its models as soon as 2017. TNGA is Toyota’s initiative to design, develop, and build more efficient vehicles to help improve fuel efficiency, reduce thermal heat levels, and, overall, make efficiency improvements to its vehicles.

The new engines will include a total of nine engine designs offered in seventeen different versions. The TNGA engine designs will feature both gasoline, hybrid, and electric options. These engines will be installed in up to sixty percent of its vehicles, starting in 2017 and continuing through 2021 in models found at Toyota dealers in Southern California and globally. The engines will also be incorporated along with new drive systems and transmissions Toyota is creating to work together with the new engine designs.

Engines and Transmissions

Furthermore, Toyota is developing a total of six hybrid-electric drive systems with ten different versions, and four different transmission designs, also in ten different versions, for specific vehicle models. The overall goal is essentially redesigning the automobile from the ground up. The new designs will feature changes to vehicle weights, height, and angling of exterior components, like the hood, to reduce wind resistance.

The short-term goal is to develop vehicles to provide improved fuel efficiencies by as much as twenty percent over current models, while at the same time providing up to a ten percent increase in power during acceleration. The new transmissions, hybrid drive systems, and engines will include a variety of new electronic technologies to achieve the company’s desired objectives.

Toyota has already built and is testing the first of the new engines, which is a 2.5-liter, four-cylinder design. This engine is projected to provide a forty-one percent thermal efficiency in hybrid models and a forty percent thermal efficiency in gasoline-only models. The new electronic components used in the engine’s design allow for better combustion of fuel and increased fuel efficiency. In addition, the new design will help Toyota achieve a sixty percent reduction in emissions through the exhaust system.

In regards to the new transmissions, Toyota has not released much information about the designs currently. However, they will be compact and lighter than current transmissions and offer both 8-speed and 10-speed options. By increasing the number of speeds within the transmission, it helps reduce torque loss compared to current 6-speed designs. As a result, not only are fuel efficiencies increased and power loss reduced, but it also helps provide a lower center of gravity for better vehicle handling around corners and overall stability.

Toyota Hybrid System

TNGA also has plans to roll out a new THS-II (Toyota Hybrid System II) for its hybrid vehicle line. The THS-II will be the next generation in electric and hybrid engine and transmission designs to reduce power loss, improve acceleration, and provide longer traveling distances.
