Toyota Land Cruiser 300 Series V6 diesel outputs confirmed! Leaked documents confirm even MORE grunt for off-road icon - reports

The Toyota LandCruiser 300 Series' new diesel engine will be even more powerful than we expected, with reportedly leaked documents out of South Africa confirming LC200 Series-shaming power and torque for the new V6.

Instagram account Land.Cruiser.300 has been on a run of form with the leaked documents, having already confirmed - for the South African market at least - new specification and trim level detail regarding the GR Sport variant of the new LC300.

But today's leak is even more exciting, with the account seemingly getting its hands on specification documents for the LC300 that reveal the exact power and torque figures for the both the diesel and petrol engine.

New Toyota Land Cruiser 300 Series GR Sport details and launch date leak: Time's up for 200 Series as countdown to unveiling begins Just what is a clean diesel? Land Cruiser 300 Series' monstrous twin-turbo V6 diesel engine explored LandCruiser news and reviews

Let's start with the one most pertinent to Australia - the twin-turbo-diesel 3.3-litre V6. According to the documents, that powertrain will produce a whopping 225kW at 4000rpm, and 700Nm from as low as 1600rpm.

Japanese sites had the torque figure at 697Nm, so while the gain isn't massive, 700 is still a nice, round figure. Perhaps more important, the smaller (in its number of cylinders, that is) engine comprehensively shades the outgoing 4.6-litre V8 unit, which makes 200kW and 650Nm.

The site also lists the outputs for the new turbocharged V6 petrol unit, and it too is a beast, reportedly producing 305kW at 5200rpm, and 650Nm at 2000rpm.

The leaked documents also confirm diesel and petrol engine options, and point to the GR Sport trim being offered with a choice of either fuel.

No matter which one you aim for, the GR Sport trim will be equipped with five driving modes, paired with adaptive suspension, and both are equipped with a 3D Terrain Monitor.

Also revealed in the documents are two accompanying trim levels that will bookend the GR Sport, an entry-level GX-R and top-spec ZS - at least for the South African market.

The new LC300 will reportedly be bigger in almost every key dimension than the vehicle it replaces, stretching some 4970mm in length, 1985mm in width and 1870mm in height, and it will ride on a 2900mm wheelbase.

The news matches information CarsGuide has received, and adds weight to comments made by Toyota Australia's VP of sales and marketing, Sean Hanley, that the new model would further the LC story.

"The powertrain of any future LandCruiser will be built to deliver. It will deliver on power, torque, towing and off- and on-road capabilities. And I am supremely confident that with whatever we do, it will continue to remain a very capable vehicle all round," Mr Hanley says.

"The LandCruiser needs to be capable. It needs to be able to perform, drive, tow, as expected of a LandCruiser.

"It has a huge heritage. It's a legend, actually, of capability in the Australian landscape. It’s clear that the number of cylinders are cubic capacity are not the only things that determine the powertrain performance."
