How fast can a Lexus 570 go?
In stock form, the LX 570 tops out around 137 mph (about 221 km/h), with a 0–60 mph sprint of roughly seven seconds. Real-world speeds vary by year, trim, and condition.
Performance snapshot
The LX 570 is a full-size luxury SUV powered by a robust V8 and built for highway cruising as well as off-road capability. It sits on an advanced 4WD system and shifting through an 8-speed automatic transmission, delivering power to all four wheels. It’s important to note that the LX 570 nameplate was used on models through the 2021 model year in the U.S.; Lexus subsequently introduced the LX 600 with a different powertrain for newer buyers. The top-speed figure cited here is representative of typical LX 570 configurations from its production years.
Key performance specifications for the LX 570 include engine output, drivetrain, acceleration, and top speed.
- Engine: 5.7-liter V8 producing about 383 horsepower and 403 lb-ft of torque (roughly 546 Nm).
- Transmission: 8-speed automatic transmission.
- Drivetrain: Full-time four-wheel drive with off-road assist features; optional crawl control on some trims.
- Top speed: Electronically limited to about 137 mph (approximately 221 km/h).
- 0–60 mph: Typically around 7.0 seconds, depending on year, weight, and configuration.
- Curb weight: Roughly 5,900–6,000 pounds (2,700–2,720 kg), depending on options.
In practice, these specs reflect the LX 570’s role as a luxury, shuttling-family SUV with strong highway performance and notable off-road capability rather than a sports SUV.
Reality check: top speed limits and driving behavior
Automakers apply electronic limits to protect engines, tires, and occupants, especially on heavy, luxury SUVs. Real-world top speeds are also influenced by cargo load, passenger weight, roof racks, and road conditions. For safety and efficiency, most drivers will not approach the official top speed in everyday driving.
What factors influence top speed in practice
Before listing the factors, it’s worth noting that the published top speed is a best-case figure under controlled conditions. Several real-world elements can raise or lower the speed you can achieve:
- Vehicle weight and cargo: Extra weight reduces acceleration and top-end performance.
- Tire choice and speed rating: Tires must support the vehicle’s intended speeds; incorrect tires can limit top speed.
- Aerodynamics and roof equipment: Roof racks, spoilers, and sunroofs can affect drag and efficiency.
- Engine and transmission health: Proper maintenance ensures consistent power delivery.
- Environmental conditions: Altitude, temperature, humidity, and road surface all influence power and grip.
- Electronic limiter settings: The factory top speed limiter caps the maximum velocity for safety and reliability.
Taken together, these factors mean that the official top speed represents a controlled scenario, not an everyday guarantee for every LX 570 driver.
Summary
The Lexus LX 570’s official top speed sits around 137 mph (about 221 km/h), with a 0–60 mph time near seven seconds. Its 5.7-liter V8, 8-speed automatic, and full-time four-wheel-drive system define a fast, capable luxury SUV geared for highway cruising and off-road readiness rather than high-performance sports driving. Real-world speeds depend on model year, trim, load, tires, and road conditions. For buyers, the LX 570 prioritizes comfort, capability, and refinement over outright acceleration.
