How fast is the Lexus LS?
Across today’s Lexus LS lineup, acceleration is brisk but the car’s strength lies in refined, smooth power rather than outright sports-car speed. The quickest configuration is the rear‑wheel‑drive LS 500, with the all‑wheel‑drive variant a touch slower; hybrids sit between these in their own way. Top speeds for most trims are electronically limited to about 130 mph.
Speed in numbers: current LS lineup
The following figures reflect common factory estimates for the latest LS models sold in the United States. Real-world times can vary based on tires, weather, testing method, and vehicle condition.
- LS 500 (rear‑wheel drive): 0–60 mph in about 4.6 seconds; top speed limited to 130 mph.
- LS 500 (all‑wheel drive): 0–60 mph in about 4.9 seconds; top speed limited to 130 mph.
- LS 500 F Sport: 0–60 mph in roughly 4.7 seconds; top speed limited to 130 mph.
- LS 500h (hybrid): 0–60 mph in roughly 5.0–5.5 seconds, depending on configuration; top speed limited to 130 mph.
In practice, the LS emphasizes a serene, controlled surge rather than a raw, track‑ready push. Even the sportier variants aim for a balanced blend of comfort and confident acceleration suitable for daily driving and long cruising.
What influences acceleration and top speed
Several factors shape how fast a Lexus LS goes from standstill to highway speed, and how quickly it reaches its top speed. The following elements play a major role across the lineup.
- Powertrain: A 3.5-liter twin‑turbo V6 in the LS 500 delivers about 416 horsepower and 442 lb‑ft of torque, paired with a 10‑speed automatic transmission.
- Drivetrain: Rear‑wheel drive tends to yield the quickest 0–60 times, while all‑wheel drive adds weight and typically slows acceleration slightly.
- Tires and ride settings: Low‑profile performance tires and sportier suspension tuning can shave tenths of a second but may affect ride comfort and grip.
- Weight: The LS remains a large, luxury sedan; curb weight generally sits well above 4,000 pounds, which moderates peak speed but supports a smooth, stable ride.
Ultimately, the LS’s speed figures are framed by refinement, quietness, and a luxurious driving experience rather than blunt acceleration numbers.
Variant details and performance technology
Understanding the powertrain and configuration helps explain the numbers above. Here are the key specs that commonly define performance across the current LS lineup.
- Engine: 3.5-liter twin‑turbo V6 delivering around 416 hp and 442 lb‑ft of torque in the LS 500.
- Transmission: 10‑speed automatic with adaptive shift logic and drive mode customization.
- Top speed limiter: Electronically controlled, typically set at 130 mph across LS variants.
- F Sport tuning (where applicable): Enhanced steering and suspension calibration aimed at sharper handling while maintaining luxury comfort.
With these elements, the LS achieves solid performance without compromising the refined, quiet character that defines the model line.
Summary
The Lexus LS combines comfortable, confident acceleration with a focus on luxury and smoothness. Expect 0–60 mph times in the mid‑4‑second range for the RWD LS 500, slightly slower for AWD, and a broader 5.0–5.5 second window for hybrids. Top speeds are generally limited to 130 mph, reflecting the model’s emphasis on refinement over raw speed.
