New 2.0 Liter Engine & Hybrid System Coming Soon to Lexus Vehicles

“Lexus

Toyota has announced a new 2.0L four-cylinder Dynamic Force engine today that will find its way into the Lexus lineup in both conventional and hybrid form. Let’s break down the tech.

2.0-liter Dynamic Force Engine, a New 2.0-liter Direct-injection, Inline 4-cylinder Gasoline Engine

The new Dynamic Force engine will use high-speed combustion technologies and a variable control system to achieve world-leading thermal efficiency — 40% for gasoline and 41 percent gas-electric hybrid. This efficiency reduces energy loss and increases the power output.

Toyota also points out that the new engines “achieve increased torque at all engine speeds―from low to high rotations―and will comply with expected future exhaust regulations in each country in advance”.

The detail released today is extensive, but here we have a chart that outlines the key engine technologies:

The maximum power for the 2.0L Dynamic Force engine will be 169 horsepower at 6,600rpm and 151 lb.ft of torque at 4,800rpm.

2.0-liter Toyota Hybrid System (THS II)

There will be a new hybrid system for 2.0-liter engines that applies the same size and weight reductions first introduced in the the fourth-generation Toyota Prius. The new system improves driving performance while retaining fuel efficiency — as an example, it will reduce engine rotations while accelerating by drawing increased electric power from the battery.

The new Power Control Unit is 20% smaller and 10% lighter than the conventional 1.8-liter model, allowing it to be placed directly above the transaxle:

The new Nickel-metal Hydride Battery has also been reduced in size:

The 2.0L Dynamic Force engine will generate 143 horsepower in its hybrid configuration, with the electric motor rated at 107 horsepower. There has been no mention of the combined horsepower of the two engines.

Not so sure if that was ever the case really.
What I am telling you is that it was the case - they had diesel options for Tundra, Tacoma/4Runner as well as passenger cars with running prototypes in North America. Just not sure if that whole program was scrapped when the VW scandal broke because I haven't heard anything about it in 8 months or so.

I assume that no diesels in EU makes sense, and if they're going that route, they may have pulled the program for diesels here as well.

Just not sure if that whole program was scrapped when the VW scandal broke (+ major push for electrification) because I haven't heard anything about it in 8 months or so.

Yes, but keep in mind that their sales of diesels in Europe at one point were likely close or more than 400,000 per year! So their main development for diesel would be EU (Russia and Middle-East barely sells any diesels, this is what they call EMEA region and how Toyota works - Europe, Russia and Middle East), and if they scrapped it in EU in 2010 or so, when they decided to go full hybrid and BMW diesels for some small diesel sales, then it likely scrapped the program for passenger diesels in USA too?

But maybe the case was that they would do their new 4cly truck diesels in Tacoma, which certainly made sense, since it is world engine, designed to pass all emissions everywhere (and will pass most stringent EU emissions that are coming in 2020) and that they simply decided to not do it due to VW fallout? These engines were introduced in 2016 so they are not on the chart, but are definitely considered as next-gen by Toyota. For Tundra, they could have turned to Isuzu, since Isuzu has a long history of doing GM truck diesels.

In Russia Land Cruiser and LX sell in Diesel mostly, and TMC sells a lot of them.

I was not aware that LC and LX sold that well in diesel from in Russia, since diesel and hybrid sales there are usually not big... Found this article where #1 and #2 diesel sellers in RU are Prado and 200 :). In Western Europe it is like Golf and Focus, or something like that.

Keep in mind thats still only 13k vehicles per year. Small number to produce brand new engine for.
