Lexus has trademarked the GX 550 nameplate in Costa Rica, suggesting there’s a new powertrain and likely a brand new next-generation model in the works. The trademark was registered in Costa Rica on September 7th, and discovered by Motor Trend shortly after.
And what kind of engine would power the GX 550? It’s almost certainly some variant of the twin-turbo V6 from the Toyota Land Cruiser & next-generation Lexus LX, though that model has been trademarked as the LX 600. This suggests the GX 550 will have reduced horsepower as compared to the flagship Lexus LX SUV.
(To think Lexus was planning to cancel the GX in 2016 and replace it with a Highlander variant. Glad to see it surviving for another generation.)
