What is the power of the LX 600 engine?
The LX 600’s powerplant is rated at 409 horsepower and 479 lb-ft of torque, paired with a 10-speed automatic transmission and all-wheel drive.
In this report, we examine the numbers behind that power, how the engine behaves in everyday driving and on challenging terrain, and how it stacks up against the model’s predecessor and its luxury-SUV peers.
Engine specifications
The LX 600 relies on Lexus’ modern turbocharged V6 architecture, calibrated to balance brisk acceleration with refined operation. The following figures summarize the key powertrain characteristics.
- Engine: 3.5-liter twin-turbo V6
- Power: 409 horsepower (305 kW)
- Torque: 479 lb-ft (650 Nm)
- Transmission: 10-speed automatic
- Drivetrain: Full-time four-wheel drive with selectable terrain modes
These numbers translate to strong mid-range torque and smooth, consistent power delivery across a broad rev range, aiding both highway cruising and off-road maneuvering.
Performance in the real world
This section translates the technical specs into everyday performance, highlighting what drivers can expect from the LX 600’s powertrain in typical use cases.
- 0–60 mph: roughly 6.8–7.0 seconds, depending on configuration and conditions
- Top speed: electronically limited to around 149 mph
- Throttle feel: responsive without abrupt turbo lag, thanks to the turbocharged V6’s broad torque band
- Transmission behavior: a quick, smooth 10-speed automatic with sport-minded shift logic
In daily driving, the 409-horsepower V6 provides confident acceleration for merging and passing, while the torque is evident for steady climbs and towing when equipped. Off-road, the engine’s broad torque helps maintain momentum across uneven terrain, especially when paired with the SUV’s terrain-tech features.
Context and comparisons
Compared with the LX’s predecessor, which used a V8 in the LX 570, the LX 600’s turbocharged V6 aims to deliver similar or better real-world performance with improved efficiency and smoother power delivery. In the broader luxury-SUV segment, the LX 600’s 409 hp places it in the upper tier of V6-powered large SUVs, competing with rivals that emphasize refinement, not just straight-line speed.
Summary
The LX 600’s 3.5-liter twin-turbo V6 delivers 409 horsepower and 479 lb-ft of torque, pairing robust, usable power with Lexus refinement and advanced all-wheel-drive systems. That combination yields strong on-road performance for a luxury SUV of its size, along with credible off-road capability when the terrain modes are engaged. Overall, the engine offers a balanced mix of speed, smoothness, and versatility for everyday driving and adventurous weekends.
