Toyota has revealed a whole host of new technologies that will be featured with the Toyota New Global Architecture (TNGA), which include new transmissions and engines. This is another step in a massive expansion of TNGA-based powertrain units, which will make their way into approximately 80% of Toyota and Lexus vehicles within the next five years.
Starting with the engines, a new 2.0 litre Dynamic Force Engine has been added to the mix, joining the existing 2.5 litre unit already found in the latest Camry. As a conventional engine, the 2.0 litre boasts a maximum thermal efficiency of 40%, and 41% when hybridised – identical to the 2.5 litre unit.
Among the features present include electric VVT-iE on the intake cam for better response and a D-4S port- and direct-injection system. The piston’s skirt sliding surface have also been subjected to mirror finishing in order to reduce friction, while narrow crosshatch grooves are created on the skirt surface by lasers to improve scuff resistance.
Laser-clad intake valve seats meanwhile, make the intake port compatible with a higher intake flow rate (better output) and tumble flow (better fuel consumption). There’s also a variable cooling system with an electronic thermostat and water pump to ensure appropriate heat management.
On its own, the engine has a maximum output of 169 hp at 6,600 rpm and 205 Nm of torque at 4,800, following a 13:1 compression ratio. In hybrid applications, the compression ratio goes up to 14:1, with output being rated at 143 hp at 6,000 rpm and 180 Nm at 4,400 Nm.
Speaking of hybrid systems, the new 2.0 litre Dynamic Force Engine will benefit from the Toyota Hybrid System (THS II), and will be used in the next-generation Corolla hatchback/Auris. The carmaker says the new 2.0 litre hybrid system is an improvement over the current 1.8 litre system being used, but has not provided output figures for now.
Instead, it says the 2.0 litre hybrid system has a new power control unit (PCU) that is 20% smaller, and 10% lighter than the 1.8 litre system. This allows the PCU to be placed directly above a new motor-generator transaxle, where the synchronous AC motor features a new rolling-coil structure with fewer wires and newly developed magnetic steel.
A new parallel reduction gear format helps to reduce the loss in the transaxle by up to 25%. The motor itself has a maximum output of 80 kW (107 hp) and 202 Nm of torque. Power is supplied to the motor from a new nickel-metal hydride battery, which is smaller and lighter thanks to a revised battery pack structure and more compact cooling system.
The capacity remains identical to that found on the 1.8 litre system – 6.5 Ah – but the battery has a higher number of cells (180 vs 168) and operates on a higher voltage as well (216 V vs 201.6 V).
Moving on to transmissions, the big news here is Toyota’s Direct Shift-CVT, which it claims is the first to employ a launch gear in a CVT. The launch gear helps improve transmission efficiency in lower gear ratios where belt efficiency is poor, for instance, starting from a full stop.
When setting off, the transmission system utilises gear drive, resulting in better acceleration while at the same time resolving the momentary sluggish feeling that was previously present. Once on the move, a highly-responsive vane pump switches the system from gear drive to belt drive.
The new setup enables the adoption of wider gear ranges of up to 7.5 for the 2.0 litre class, which Toyota claims will be a class-leading figure. Using a launch gear also results in reduced input load, allowing for smaller belt and pulley components to be used. This, along with a narrower belt angle (9 degrees from 11 degrees), result in shifting speeds that are 20% faster.
According to Toyota, the Direct Shift-CVT offers shift performance equal or greater than DCTs produced by other companies, and better fuel efficiency by as much as 6%.
For markets that demand a manual option like Europe, a new six-speed unit has been introduced. The new unit is 7 kg lighter than the existing one, and is 24 mm shorter as well thanks to thinner hubs, a revised gear stopper, a thinner case and omission of needle bearings.
Aside from improved packaging, the transmission also features the iMT (Intelligent Manual Transmission) system that provides automatic rev matching on upshifts and downshifts. The 40 kg six-speed unit is capable of handling torque figures of up 280 Nm.
Toyota has already announced plans to introduce nine engines (17 variations), four transmissions (10 variations) and six hybrid systems (10 variations) by the end of 2021. The new 2.0 litre Dynamic Force Engine, 2.0 litre THS II system, Direct Shift-CVT and new six-speed manual transmission are four of the planned components joining previously-introduced ones.
But wait, there’s more as two new all-wheel drive systems have also been introduced. The first – Dynamic Torque Vectoring AWD – is for use with petrol engines, and allows torque to be distributed to the left and right rear wheels according to driving conditions. If needed, ratchet-type dog clutches on both the front and rear wheel shafts can be used to stop the drive system rotations, which transmit driving force to rear wheels when in 2WD mode.
For hybrid vehicles, there’s the new E-Four system, which continues to use an electric motor to drive the rear wheels. The new system increases total torque to the rear wheels by 30% compared to existing versions, while a new control system optimally distributes torque to the rear wheels based on the driving conditions. These systems are part of three new AWD systems (eight variations) that Toyota has planned for use in passenger vehicles, commercial vehicles, and hybrid electric vehicles.
Looking to sell your car? Sell it with Carro.
The best just got better. Now all these new tech will trickle to Perodua.
Perodua will have a new sedan with this new 2.0 engine one day
Go Perodua!!!! Rakyat want Perodua with Toyota engines, Toyota engines that are sold in over 200 countries worldwide
Geely cars and Geely engines, only sold in China. Not allowed to be sold in first world countries.
In case if u didn know, Geely sells their cars in australia and dubai too… And that is only the 2 countries i know they have presence there
Some claim Campro enjin hv better FC
Myvi claimed FC 20.1km/l , lagi best what?
Volvo belongs to Geely, I happen to see Volvo’s all over the world
Australia not 1st world? Okayysss…
I believe John believes Australia is 4 th World country. That’s why the down under Malaysia. We more maju than Australia hoh. Mr john
Well since u said Geely not allowed to be sold in first world countries and its sold on Aussie, ergo to ur logic, Aussie is not 1st world. Which goes against reality, ergo ur logic tarak ngam with reality.
when Geely sells one or two cars in a year, this is not considered sales.
Just like Proton, sold a grand total of 1 Proton car in Singapore in 2016. You cannot call this presence or sales.
Yup. Just like Mivi presence in Maldives and Indomee. Rare like unicorn.
Hahaha. Best comment ever
Why must geely being discussed here. Mr merican jealous geely no buy Toyota stock? Instead beli stock Mercedes? Kesian.
He still dreaming Toyota will supply their new engine to P2. He forgot what engine Innova, Vios, Corrollo engine sold here use. Their own model still did’t upgrade, keep dreaming they will supply it to P2. Ya.. P2 will got the new engine, 50 years later.
Why so butthurt??? And this article is about toyota. Why so butthurt???
He trembles in fear of the potential from P1Geely. So on behalf of his ToyotaP2, he doing negative impression b4 Boyue arrives and blows away his overpriced CHR and late coming P2 SUV.
Toyota killer brakes also sold in first world country hahahaha
Takatabags oso sold in 1st world countries… oh wai
Wah. Memang berteknologi tinggi the best in the world…..
Bashers claim auto gearbox better than CVT
china engines best technology soon, very soon!
for those who were wondering why BMW and Mazda willing to collaborate or JV with Toyota and looked up on Japan No. 1 – this is one reason. the technology.
we see this today, but Toyota began this project several years ago. maybe 10 years back, who knows? i remember john and some others said BMW diesel, audi diesel and peugoet diesel hybrid is better than toyota petrol diesel until europe plans to stop using diesel soon (involving new car sales)
Nah. BMW and Mazda just needs the deep pockets of Toyota. BMW just wants to break into the JDM market. While Toyota is doing community service by helping a tiny but visionary Mazda, in return for their Skyactiv.
Toyota Skyactiv
And how a relatively tiny company was able to incrementally perfect the combustion engine way faster and better than a giant like Toyota.
I just wonder why Toyota not moving towards turbo technology engine?
According to their Executive Manager for their Technical Program in Powertrain and what-not (name too long, I can’t remember), Toyota already has Lexus for that.
still no turbo???
Again, no.
They already have Lexus for that, which Ben Schlimme, Toyota Technical Center’s Executive Program Manager for Powertrain & Regulation and Advanced Planning & Research for powertrains (see, long name, and I had to copy paste it) basically said. Toyota’s turbo deployment depend on demand, and most regions, especially the US one of their largest market, doesn’t quite demand turbos for their sensible Toyotas. Right now their turbo program is focused on Lexus, where price isn’t as much of a concern since it’s a more premium brand.
Besides, this new engine already shows considerable performance and economy boost without the complexity and cost of adding a turbo.
Toyota still offering obsolete and dinosaur technology to Malaysian.
Furthermore , Toyota Fan boys still says Toyota is good and blah blah..
So in summary Toyota is not premium car just a bread and butter brand .
No wonder the vios, corolla and Avanza ride like SAMPAN …
Kenot blem mah, most Malaysians just want their cars to be comfortable and reliable. Which I think is a reasonable mentality….
Old engine please pass to perodua, so we can buy affordable vehicle from them.
ala komen2 bkn toyota bg komisen pon….
Thats what you get when you buy into subaru. Its 4wd technoligy. Unfortunately, toyota not sharing its hybrid with subaru.
Pipu going for electric car oledi but they are still designing internal combustion engines. Haiyoh.
other competitor already using lithium ion battery, and soon solid state battery. Yet toyota in year 2020 will still be using “nickel-metal hydride” battery, fundamentally same as its first generation prius.
There are still purist petrolheads out there to suck money from.
Best bet is still a kimchi
If the gasoline engine is still on demand, I do not understand why Toyota still insist of using naturally aspirated engine while other automakers are slowly moving to turbo. This is just a direct injection with variable valve timing, why come with new term of dynamic force engine.
In current new trend more and more automakers go for smaller displacement engine with forced induction, turbo technology. A car with 1.5 turbo engine is equivalent to 2.5 engine, meanwhile the fuel consumption is about the same or lower. In many countries small displacement can save more on roadtax or insurance kind of charges. Force induction engine is proven is greater in city driving.
Differences in idealogy. Downsizing is predominantly an European trend. Majority Japan still believes there’s room to perfect the NA blocks. Take Mazda as a prime example with their Skyactiv suit of brilliant engineering. Also, turbo engines aren’t exactly the most simplest of forms out there. And most buyers aren’t ready to dwell into the force induction route, all thanks to the undying perception of turbos being performance oriented and difficultly unreliable.
That’s a piece of great news. I’m a fan of N/A engines since I sold my turbocharged car. Ones cannot defy that turbocharged engines operates at more stressful parameters. I had been dealing with blown head gaskets, cracked valves, pre-ignition and so on.. AND, you’ll never get enough with turbos.. The urge to go quicker is really addictive.. Then I decided to settle down with an N/A, what a relief.. A relief from minding about possible upgrades and headache-induced consequences.. Yep, I did almost all works on my cars myself if time permits.. So, finding out a reputable marque is upgaming their N/A offerings is mostly welcome by me..
Does CVT in toyota Malaysia market comes with this direct shift-CVT tech?
