Toyota presents new powertrains for TNGA platform (video)
Toyota introduces new motor variants for its Toyota New Global Architecture (TNGA) platform. Variations include a 2-litre hybrid motor and new all-wheel drives. The latter feature an AWD set-up for hybrid systems as well.
Among the new developments by Toyota are the 2.0-liter hybrid system, and 4WD systems that join a new continuously variable transmission (CVT) and 6-speed manual transmission aimed at making more efficient cars.
The new hybrid system for 2.0-liter engines applies the same size-reducing, weight-reducing, and loss-reducing technologies used in the fourth-generation Prius, according to press release straight out of the news room in Japan. When accelerating, the hybrid system reduces engine rotations while drawing increased electric power from the battery, thereby delivering a linear and lengthened sense of acceleration.
The hybrid AWD system is called E-Four. Toyota says the system increases total torque to the rear wheels―which are electrically driven―by 30 percent compared to existing versions. Moreover, both the Dynamic Torque Vectoring AWD system and the new E-Four system feature AWD Integrated Management (AIM), which harmonizes engine, transmission, braking, and 4WD systems to improve handling and stability regardless of road surface conditions.
Toyota wants to increase the number of models equipped with the new powertrain units worldwide from this spring onward. TNGA enables the Japanese carmaker to position the battery pack underneath the rear passenger seat rather than under the trunk, thus increasing the available space inside their (plug-in) hybrid vehicles.
