The FJA300 will introduce a new engine into the Toyota range: the 3.3-litre turbo diesel six-cylinder called the 'F33A-FTV'.
While some rumours claim it will employ a V6 configuration, Japanese publication BestCarWeb has suggested it could even be presented to the world as a four-cylinder engine.
However, one plausible rumour is that the engine will be an inline-six – a common engine in previous LandCruiser generations – shared with the upcoming rear-wheel-drive Mazda 6 and CX-5.
Toyota has a minority stake in Mazda, and the two car makers have made announcements in recent years pointing to shared technical developments.
Giving credence to these reports is the power output, with claims Mazda's 3.3-litre diesel will produce 210kW and 600Nm – very similar figures to the 200kW/650Nm offered in the current LandCruiser.
We do know this engine will replace the venerable turbo diesel V8 found in the 200 Series and will be the workhorse of the LandCruiser range.
As previously reported, the 300 Series will get a 3.5-litre twin-turbo petrol V6 hybrid engine, to be named 'V35A-FTS'.
Though relatively new, a non-hybrid iteration of the twin-turbo engine has been fitted to the most-recent Lexus LS500 limousine where it delivers 310kW and 600Nm, while the LS500h offers hybridisation without the benefit of turbochargers.
With the LS500h weighing in at around 2300kg, fuel economy is claimed at 6.6 litres per 100 kilometres – though that figure is expected to jump to 10.1L/100km in the heavier, less aerodynamic, twin-turbocharged and four-wheel-drive LandCruiser.
