The engine

V35A

3.4L Twin-Turbo V6

The twin-turbo V6 trades a V8's character for a thick wave of low-end torque, deliberately tuned in the GX 550 for muscular off-road pulling power rather than peak horsepower.

This is Toyota's V35A-FTS, the 3.4-liter twin-turbo V6 introduced to replace the long-serving 5.7-liter V8, and it's shared across the Land Cruiser 300, Tundra, Sequoia and Lexus LX 600.

Lexus deliberately fits the GX 550 with smaller turbochargers than other applications, giving it less peak power but more torque, better suited to low-speed off-roading.
The engine made more torque than the V8 it replaced, the whole point of Toyota's switch away from the 5.7-liter.
It was the centerpiece of Toyota's move to retire its big naturally aspirated V8s across its flagship trucks and SUVs.
