Fresh rumours claim the new Lexus LX will be offered with a twin-turbo V8 petrol engine, a powerplant seemingly not on the cards for the closely related new Toyota Land Cruiser 300.

According to CarsGuide (leaning heavily on an @allcarnews post), a new twin-turbo eight-cylinder unit will replace the current naturally aspirated 5,7-litre V8 engine, which offers 270 kW and 530 N.m in the outgoing LX.

In addition, the fourth-generation LX is set to be offered with the Japanese firm’s twin-turbo 3,5-litre V6 petrol powerplant, which earlier reports suggested would also be employed by the Land Cruiser 300. In the Lexus, the V6 will likely be electrified.

Toyota’s upcoming replacement for the Land Cruiser 200 is widely expected to ditch both the 243 kW/460 N.m 4,6-litre V8 petrol engine offered in some markets and the 195 kW/650 N.m 4,5-litre V8 turbodiesel sold here in South Africa, with reports pointing to an uprated version of the company’s 2,8-litre, four-cylinder oil-burner.

The latest information out of Japan suggests the new Land Cruiser 300 will launch only in 2021, with the new LX likely to follow soon thereafter.
