Toyota has revealed its new powertrain line-up for vehicles that are based on the TNGA (Toyota's New Global Architecture) platform. The company intends to deploy these new powertrains in its vehicles from 2017. Toyota claims that the newly developed powertrains are lighter and more compact, as compared to the ones currently being used. They have been designed to keep the center of gravity as low as possible, with an intent to improve the car's handling characteristics. According to the automaker, the new powertrains offer up to 20% better fuel efficiency, up to 15% lower emissions and around 10% more power.

New 2.5-litre petrol engine
The company's new internal-combustion power plants have been named "Dynamic Force Engines". The line-up includes a 2.5-liter direct-injection in-line four-cylinder petrol engine that uses high-speed combustion and other efficiency-based technologies. The automaker claims that this engine can extract a thermal efficiency of 40% when used in gasoline-powered vehicles and 41% in hybrid vehicle applications.

New 8-speed and 10-speed Automatic Transmissions
Toyota has further introduced two new automatic transmissions: an 8-speed Direct Shift-8AT and a 10-speed Direct shift-10AT. Toyota claims that both these gearboxes have been designed while taking various measures for minimizing energy loss and improving transmission efficiency. The clutch has also been optimized to reduce clutch torque loss by approximately 50%, as compared to a conventional 6-speed transmission. The manufacturer also claims that these new automatic transmissions are more compact and lighter than comparative conventional transmissions.

Toyota Hybrid System II (THS-II)
Toyota has also improved its hybrid system for 2.5-liter engines with the development of the new Multistage Toyota Hybrid System II (THS-II), which is now also suitable for rear-wheel-drive-cars. The company claims better performance and efficiency from the new hybrid powertrain, owing to appropriate weight reduction and high-thermal efficiency of the new 2.5-litre engine. The plug-in hybrid system now gets a large-capacity lithium-ion battery that will likely increase the EV range of Toyota vehicles.

Toyota is working on many other new powertrains. By 2021, the automaker plans to introduce 17 versions of nine new engines, including the above-mentioned 2.5-liter engine. It will also be revealing 10 versions of four transmissions and 10 versions of six hybrid systems.

Knowing Toyota, they are sure to engineer the heck out of these engines and drivetrain. But in the world of downsizing engines, isn't 2.5L huge for 2021 standards? The 10AT sounds exhaustive! The 9 speed Merc tranny is blamed for constant shifting so not so sure about a 10 speed box.

Should i postpone my decision of buying new crysta 2.4 manual. Already the vehicle is booked. Kindly share your valuable views. Thanks.

These are unlikely make into crysta at least in near feature. Crysta engine and transmission is locally manufactured in india and they have invested for a new plant for this. Also the engine and transmission is aimed towards US market. No need to worry it would not make it into india at least for next 5 years.

How come I don't see a diesel engine in their plans?

I doubt any of these engines are coming to India soon. If Toyota thinks it's worth putting in Indian cars (incentives, tax benefits etc) , they may come after a few years with a facelifted version.

There's no way we're giving up big diesel motors so easily. We need them for the Torque and FE (respectable, not good FE) for the MUV/SUV.

Not necessarily. In fact, common sense has prevailed and its now accepted that outside the lab test and 'controlled environment' fuel economy, in the real world downsizing is working out to be pretty futile for fuel economy, especially in decent sized vehicles.

Not that V8 engines and 3000cc+ engines are coming back in a big way, but apt engine for the vehicles size and intended usage.
Have to give it to Mazda for not jumping in the bandwagon and downsizing like crazy, though Toyota has introduced 1000cc and 1200cc turbo petrol engines for the European market.

Also the models that are intended for this new 2500cc engine might be Camry and above and also the Crowns and Lexus models.
In short the models above the Corolla and derivative family will get the new engines and transmissions and the smaller models will get the 1.0l, 1.2l turbo petrol engines that have been developed for the European market.

Has downsizing ever helped keep environment clean, and fuel demand low. Bigger engines at lower RPM are actually more thermal effecient, cleaner and long lived.
Recently on a long trip of 3650km with friends, a 2.2 Lit in XUV500 W10 AT with 5 people & Luggage consumed 227 Lit which is 16.08 (MID showing 17) while a 1.5 Lit Duster AWD with 4 and luggage consumed 223 Lit which is 16.37. But here the XUV had a Torque converter AT and was at least 400kg heavier than Duster.
