It looks like the LX570 might not be the most powerful of Lexus's largest SUV.
For the old school lover of big engines, lots of room inside, and a massive gas-guzzling engine, it doesn't get much better than the Lexus LX570 right now. It's built on the Toyota Land Cruiser's body-on-frame platform, complete with a 5.7-liter naturally aspirated V8 engine producing 383 horsepower and 402 lb-ft of torque. The current generation has been around since 2008 and has been facelifted three times yet Toyota doesn't seem in a hurry to redesign either the Land Cruiser and by extension, the LX. What has turned up though is a trademark filing from Lexus in order to secure the LX600 name.
If the rumor mill is to be believed, a new Land Cruiser is slated for 2021. That seems highly unlikely, but if it was the case then the LX600 name could designate the next generation. What's most interesting is that the LX570 designation denotes the use of a 5.7-liter engine, and if Lexus was to hold true to that then it could signify that the LX is close to getting a larger displacement engine. A 6.0-liter V8 would be a bold move, though using a turbo or two to increase power would be the more financially advisable route for both company and customer.
More likely, the new designation will be for the new twin-turbo V8 Lexus is reputed to be working on, which we can only hope is an unholy and unnaturally aspirated beast of a V8. What truly gives us hope here is the lack of a lower-case h" at the end of the name that would denote a hybrid powertrain.
Given that Lexus has only just secured the LX600 name, it's going to be a while before it turns into a badge on the back of a vehicle. We'll probably have to wait until later in 2021 to find out if it's for a naturally aspirated V8 version with a larger displacement, a whole new twin-turbo engine, or a completely new generation of the Japanese giant luxury SUV.
