Toyota has announced initial details of its new powertrain lineup that will be deployed in its Toyota New Global Architecture (TNGA) modular platform programme. The plan will see the introduction of 17 versions of nine engines, 10 versions of four transmissions – including multi-geared automatic transmissions and a new continuously variable transmission – as well as 10 versions of six hybrid systems over the next five years.
Developed along TNGA lines, the “Dynamic Force Engines” will be introduced starting from 2017, and the automaker says the new units are expected to feature in more than 60% of its vehicles sold annually in Japan, United States, Europe and China by 2021.
The new engines employ high-speed combustion technology and a variable control system. They also achieve greater thermal efficiency, resulting in high output, due to a reduction in energy losses associated with exhaust/cooling systems and the movement of mechanical parts, among other things. They will be around 10% more powerful and have around 20% better fuel economy.
The lineup will include a new 2.5 litre direct-injection four-cylinder engine, claimed to have one of the world’s best thermal efficiencies at 40% when used in gasoline-powered vehicles and 41% in hybrid vehicle applications.
Also announced at this initial stage were two new automatic transmissions, an eight-speed Direct Shift-8AT and a 10-speed Direct shift-10AT. The units feature widened gears and a newly-developed high-performance compact torque convertor, which offer a broader gear lockup range.
To minimise energy loss and heighten transmission efficiency, gear tooth surfaces were processed using a new technique for a lower coefficient of friction during gear engagement, and the configuration of the friction material used inside the clutch has been optimised to reduce clutch torque loss by approximately 50% during rotation when compared to a conventional six-speed transmission).
The automaker also revealed developments on its Hybrid Synergy Drive front with the introduction of a new, high-performance Multistage THS II system for rear-wheel-drive vehicles. Enhanced for 2.5 litre engine applications, the Multistage THS II will offer improved start-from-stop acceleration performance and a more direct feel.
The system for plug-in hybrid vehicles (PHEV) has also been enhanced. A new dual-mode drive system allows the electric motor – previously used only as a generator – to provide direct driving power, resulting in improved driving performance, even when in EV mode. A large-capacity lithium-ion battery that increases the EV-mode cruising range to 60 km or more is also part of the improvements.
Alongside the new TNGA power and drivetrain units, Toyota also anounced that it will be placing more emphasis on the development of hybrid technologies – it’s set to reorganise its development structure starting from next year and increase the number of hybrid technology development personnel by around 30% over the next five years.

Wow that a lot of engines. They should into new engine. Their current engines are old
“…over the next 5 years…starting from 2017…”.
So the new norm for thermal efficiency for an ICE is 40%. In other words, most of our current engine are running at less than 40% or theoretically speaking, its running at only 25%. 60 to 75% of energy is wasted when we use an Internal Combustion Engine(ICE).
Maybe PT can run an article on Thermodynamics/thermal efficiency for our commentators to know more about ICE.
Toyota TNGA platform engines & transmissions are good on papers but Toyota should concentrate on PHEV or Full Hybrid as its more efficient & environment friendly.
they can use those for the next decade n still be relevant, economies of scale redefined… such smart busimess sence, bt u need bucket load of capital to spend on this…
This sounds all fine and dandy but ASEAN is gonna be left out from the good stuff..we are just only getting Dual VVti engine families here..a full 6-7 years after europe etc…expect this tech to probably exist in the flagship cars for now..your next vios avanza..innova(launched) will all still run on third world internals…
Will they also be making use of advanced high strength steels? Right now they’re just adding more material and structures on regular <600MPa UTS high strength steels in order to meet crash safety standards. Toyota is still widely using 300+MPa regular steels and 500+MPa high strength steels, with no AHSS in sight.
Good for them to deploy these new powertrains in 2017. No doubt, these engines and gearboxes will be used up till at least 2030 with minimal (or no) changes, considering Toyota's track record.
Bashers says HPF is syok sendri woh. So means toyota oso syok sendri, according to their logic.
Are you talking about yourself since you’re in here everyday BASHING away. Get a hobby dude. It’s so unhealthy doing the cyber warrior keyboard hero thing. It’s not good for your fragile mental health. May you find peace bro.
If it was p1 the bashing reaches 9000 comments
Nope, Toyota not syiok sendiri. Proton is. Toyota has cash to spend on R&D, unlike some company, duit tarak tapi guna duit Rakyat for some superb handling and syiok sendiri turbo.
Honda turbo also smoke your Proton kau kau la. Got any Honda NSX level proton or not? Perdana pun ambik dari Honda. Haihzzz
Meanwhile Malaysia will be the dumping ground to clear off all those older generation engines.
For the hybrid segment, there is no use improving the internal combustion engine and the electric motor without putting more effort to improve the batteries as well. If you could make batteries smaller , it does not need to eat up so much boot space for a hybrid car. If you can make batteries lighter, it will improve handling and braking ability due to lower mass of the vehicle.
Buy parallel import from Jipun if you want first hand, Authorised dealer channel will take you ages, and you may be fitted made in Tai Lend version…see…our money is not money…ang moh money is real money although technically we are paying similar USD in import price :p
Still no turbo? No thanks.
