Just what is a clean diesel? Land Cruiser 300 Series' monstrous twin-turbo V6 diesel engine explored

At a time when the organisation is shifting to eco-friendliness with models like the Toyota RAV4 Hybrid and Yaris Cross and Corolla Cross, the incoming LandCruiser 300 Series will be something entirely different, packing the brand's most powerful diesel engine in the shape of a new 3.3-litre V6 that will almost certainly also find its way into models like the GR HiLux.

So how does a big and thumping V6 diesel fit into the brand's eco-friendly future? The answer, it seems, is what we will soon know as a "Clean Diesel", at least according to reports out of Japan.

But before we get to that, let's take a closer look at what we know so far about Toyota's new diesel engine.

First reported in CarsGuide, and now seemingly confirmed by publications in Japan, the auto giant's iconic LandCruiser will play host to a 3.3-litre, twin-turbocharged V6 engine, replacing the much-loved V8 donk from the LC200.

That much we knew, thanks first to our sources, and then to internet sleuths in Europe who uncovered a new engine code for the LandCruiser, reportedly from Toyota’s own technical information site used by mechanics, repairers and accessory installers.

Users have reported stumbling across a new series of engine codes for the LC300, with the most pertinent entitled “F33A-FTV”.

FTV, we know, is the model code attached to Toyota's diesel engines - the HiLux, for example, is powered by Toyota’s 1GD-FTV engine - and the “33” bit seemingly pointed to a 3.3-litre engine.

But the story moved further along this week, when Japanese outlet Creative 311 - which was quoting dealer sources - reported that the incoming LC300 will be packing a new 3.3-litre diesel V6 engine that produce a whopping 230kW and 687Nm, paired with a 10-speed automatic transmission, a GR Fortuner will be a super SUV indeed.

Those are big outputs, but the continuation of a diesel engine in a vehicle like the LandCruiser is no surprise. Toyota in Australia understand the important of the fuel type, recently telling CarsGuide that some people were "particularly wedded to diesel", with the torque-rich tech.

"We know that some people are particularly wedded to diesel," said Toyota Australia's General Manager of Product Planning and Development, Rod Ferguson. "Some farmers, for example, store diesel on their property, or it’s more accessible, or you’re in a region where you can’t have petrol."

The big question, though, was how a diesel powerplant would fit with the brand's eco-friendly future. And for the answer, we turn to Japan's Best Car Web, which is reporting that the new engine will be billed a "Clean Diesel", and one that will no doubt be marketed in countries like our own, where the fuel type is still incredibly popular.

Mazda, too, is investing in new diesel engines - and specifically a new 3.3-litre inline-six diesel - with Mazda in Europe promising: "we have a new approach to diesel engines. We will show you how clean and very efficient diesel engines can be.”

For that brand, the answer - it seems - will be an adoption of Mazda's clever SkyActiv-X spark-controlled compression ignition technology, but how will Toyota manage a clean diesel future?

We know the brand is "actively considering" diesel hybrid technology, with the brand's executives telling CarsGuide that "it's technically feasible, and there are open discussions, definitely. It all comes back to our desire to driver down our C02 emissions."

But that is not expected to appear ahead of 2022 - according to international reports - and is yet to be mentioned alongside the LC300, so it's unlikely electrification, at least as far as diesel is concerned, will play a role.

All will be revealed shortly, including exactly how Toyota will balance the needs of its diesel-loving fan base and the image of its eco-friendly future, with the LC300 expected to be officially revealed in the coming weeks, ahead of a reported August on-sale date.
