How much HP does the LX 570 Super Sport have?
The LX 570 Super Sport is not an official Lexus trim, and there is no factory specification for a “Super Sport” version in Lexus’ lineup. In stock form, the LX 570 delivers 383 horsepower from a 5.7-liter V8. Any higher horsepower figure branded as “Super Sport” generally comes from aftermarket tuning, not from Lexus.
To understand what this question entails, it helps to separate the official specifications from aftermarket claims. Lexus sold the LX 570 with a 5.7L V8 producing 383 hp and 403 lb-ft of torque, while the “Super Sport” designation has appeared only in aftermarket contexts or marketing from tuners rather than as a Lexus-approved trim.
Official horsepower and torque of the LX 570
Key figures for the LX 570’s engine and drivetrain, as delivered from the factory, are listed below:
- Engine: 5.7-liter V8 producing 383 horsepower at 5,600 rpm
- Torque: 403 lb-ft of torque at 3,600 rpm
- Drivetrain: Full-time four-wheel drive with an 8-speed automatic transmission
In summary, the stock LX 570 checks in at 383 hp and 403 lb-ft of torque, and there is no Lexus-issued “Super Sport” variant with a different horsepower rating.
The “Super Sport” label in the market
No official Lexus documentation shows a model called “LX 570 Super Sport.” In the field, some shops or aftermarket brands attach the “Super Sport” badge to modified LX 570s or promote performance packages that promise higher horsepower, but these are not factory Lexus offerings and the horsepower can vary widely depending on the specific kit.
Common aftermarket approaches and what to expect
Before considering any aftermarket package, it helps to know the typical categories that tuners promote for high-performance upgrades.
- ECU remapping or engine calibration to optimize air-fuel mix and timing
- Exhaust system upgrades to reduce backpressure and potentially improve power delivery
- Forced-induction options such as supercharger or turbocharger kits (if available for the platform)
Note: Gains from aftermarket work vary by kit and installation quality, and they can affect reliability, warranty, and legality. Always verify claims with independent testing and ensure compatibility with your vehicle’s generation and drivetrain.
Summary
The official LX 570, powered by a 5.7-liter V8, produces 383 horsepower and 403 lb-ft of torque. There is no Lexus-issued “LX 570 Super Sport” model; any such designation found in the market comes from aftermarket tuners with variable results. For those seeking more horsepower, options exist in the aftermarket space, but they come with trade-offs to consider.
