This report contains Toyota Motor Corporation's development plan for internal combustion engines and the latest progress of Toyota New Global Architecture (TNGA), a new product development approach that was introduced in 2012.
Toyota will introduce 14 new engine variations with high thermal and fuel efficiency between April 2014 and 2015. The engines will be used in 30 percent of the vehicles that are sold by Toyota globally in 2016. The new 1.0- and 1.3-liter engines were used in April 2014 in the Passo and the Vitz, respectively. The Passo fitted with the 1.0-liter engine achieved the highest fuel efficiency of 27.6km per liter (in JC08 test method) among the gasoline-fueled non-mini vehicles in Japan. In July 2014, the first 2.0-liter direct-injection turbo engine developed for the Lexus brand was fitted in the Lexus NX. These reflect Toyota's initiatives to improve environmental performance of its vehicles powered by internal combustion engines as well as hybrid vehicles.
The all-new Prius to be launched in 2015 will most likely be the first model built by TNGA. TNGA will be applied initially to the B, C and K platforms of front-wheel-drive (FWD) vehicles. It is said that Toyota will apply the TNGA in phases to rear-wheel driven upper-end vehicles and commercial vehicles as well. Eventually, TNGA will be applied to all platforms.
Toyota is meeting with part suppliers to discuss the co-development of parts that may be shared across several models toward full implementation of the TNGA. Among them, Denso has already developed an air-conditioning unit that may be installed in B to D segment models regardless of the model or the automaker.
