The slow drip feed of 2021 Toyota LandCruiser 300 Series information continues, even as its manufacturer remains tight-lipped.
The latest leaks come courtesy of Kurdistan Automotive Blog, which has shared technical drawings of the flagship four-wheel drive’s interior and exterior plus a photo of the body shell.
As expected for a new generation of LandCruiser, the 300 Series doesn’t reinvent the wheel. Instead, it’s an evolution of the current model’s design.
The most notable changes are a slightly more pronounced up-kick to the belt line and slimmer tail lights.
Inside the changes are rather more pronounced, including the addition of a larger, tablet-style touchscreen infotainment system measuring 12.3 inches and featuring Android Auto and Apple CarPlay.
The current car uses a 9.0-inch touchscreen except in the GX and GXL, which make do with a 6.1-inch unit.
Leaks earlier this year gave us a close look of the centre stack in what appears to be range-topping Sahara guise, with heated and ventilated seat controls located just below the touchscreen and a row of hard buttons below those for the sound system.
There are also new features like a heated steering wheel and a Qi wireless charging pad on the centre console, as well as a larger screen within the instrument cluster flanked by analogue gauges.
Technical drawings of the switchgear reveal automatic stop/start as a new feature for the LandCruiser, while there’ll continue to be the option of a power tailgate.
Perhaps most interestingly, there’s a GR-branded start/stop button that’ll likely feature in the GR Sport model.
There are 17-inch steel wheels in the base 300 Series, with alloy wheels measuring 18 to 20 inches available.
The Kurdistan Automotive Blog has also shared the engine codes of the upcoming 300 Series range.
Some markets will continue to offer the 1GR-FE, a naturally-aspirated 4.0-litre petrol V6 engine that’s previously seen duty in Australian-market Prado, HiLux and FJ Cruiser models and continues to be offered in models like the 4Runner and Fortuner overseas.
The new diesel engine uses the designation F33A-FTV and displaces 3.3 litres, though there have been conflicting reports as to whether it’s an inline four or inline-six-cylinder engine.
Like the diesel V8, the petrol V8 available in some markets is getting axed in favour of a downsized mill.
According to the leaked pages, the LandCruiser 300 Series will use a 3.5-litre twin-turbo V6 referred to as V35A-FTS, which does duty in the Lexus LS500.
In the LS, it produces 310kW of power and 600Nm of torque and is mated to a 10-speed automatic transmission.
The 300 Series is also expected to use a hybrid version of the 3.5-litre V6.
The Lexus LS500h uses a hybrid, non-turbocharged 3.5-litre V6 with a total system output of 264kW of power.
As Toyota has been so secretive about the upcoming model, some overseas reports have contradicted each other.
One last year indicated the GR Sport would offer a twin-turbocharged 4.0-litre V8 petrol engine, while another suggested the GR Sport would offer only cosmetic and handling tweaks and no extra power.
We expect to see a debut of the 300 Series this year, though local launch timings have yet to be confirmed.
Overseas reports have indicated the new SUV has been delayed slightly.
In January, a dealer source told BestCarWeb the product outline would be released in March, reservations would open in April, and it would be officially released in May.
The recent shortage of semiconductors has pushed out those timeframes, with Japanese reservations now reportedly set to open in May and deliveries beginning in August.
