Toyota Land Cruiser 300 Series GR Sport detailed! Icon to get bigger and badder flagship ahead of August launch - reports

The Toyota Land Cruiser 300 Series story is only just beginning, with fresh news out of Japan reporting that a GR Sport model will act as a flagship model that's both bigger and more advanced than the rest of the LC300.

The reports also point to an early-August on-sale date for the all-new icon, which marries neatly with what we were expecting, but the big news is that a GR Sport model won't just change the look, but also the physical dimensions of the LC300.

According the sleuths at Japan's Best Car Web, the LC300 GR Sport - trimmed to GR-S in the model name - will go into production on July 19, roughly three weeks later than the rest of the range, which is slated for July 1.

And while the rest of the range will stretch some 4950mm in length, 1980mm in width and 1870mm in height, the GR-S model will ben 35mm longer, 15mm wider and 10mm taller, thanks to a redesigned grille, bumper, wheel arch and tyre package.

Like the rest of the range, it will be powered by a choice of turbocharged V6 petrol or 3.3-litre V6 diesel, the latter of most interest in Australia. According to Creative 311 - quoting dealer sources - the new 3.3-litre diesel engine will produce a whopping 230kW and 687Nm, paired with a 10-speed automatic transmission.

Dealer specification documents in Japan show the GR-S LandCruiser packing a new-generation Kinetic Dynamic Suspension System, which adjusts the front and rear suspension based on road conditions, as well as front and read diff locks.

You'll also get 18-inch alloys finished in a matt grey, LED headlights, GR-S bespoke front and rear design, and an on-board fingerprint reader.
