While the team at Jaguar Land Rover JLR were still in the designing stages of the new Defender they were already in the planning stages of what the ultimate Defender would look like.
And while the Defender is extremely capable in its own right as we discovered again in the muddy forests outside Goodwood while attending the Goodwood Festival of Speed in England, the OCTA takes it up more than just a few notches.
At the heart of it are two vital ingredients that sets it apart from the rest of its siblings.
While almost every manufacturer, including JLR, is heading towards electrification of some sorts and in the case of Jaguar, only electric, the OCTA is having none of that except for a bit of mild hybrid.
Its beating heart is a 4.4-litre mild-hybrid twin turbo V8 petrol engine producing 467kW and 750Nm 800Nm with Dynamic Launch Mode selected connected to an eight-speed automatic transmission with high and low range gears sending power to all four corners.
