Comfort and Ride Quality

Comfort in luxury sedans like the LS encompasses ride quality, noise levels, seating, and overall refinement. Reviews and comparisons provide insights:

  • Ride Comfort: The gas versions are noted for feeling “more sedate when not accelerating, better isolated from suspension impacts, closer to a sport sedan, but brake pedal can feel vague” (MotorTrend). This suggests better isolation from road imperfections, enhancing ride smoothness, especially on highways. The hybrid version, while not directly compared in ride isolation, shares general comfort notes like well-padded seating, but its AWD setup and additional weight (due to batteries) might affect ride dynamics.
  • Cabin Isolation: The gas versions are explicitly praised for being “better isolated from suspension impacts,” which is crucial for passenger comfort over long distances (MotorTrend). The hybrid, while likely quiet due to electric motor operation at low speeds, may not match this level of isolation, as noted in older reviews where the hybrid powertrain was described as “unrefined” (Car and Driver).
  • Seating Comfort: Both versions offer well-padded seating, with the hybrid featuring 28-way power front seats and 18-way power rear seats, compared to the gas version, which likely has similar but unspecified adjustments (MotorTrend). This suggests comparable interior comfort, with no significant difference.
  • Noise Levels: General comparisons suggest hybrids are quieter, especially at low speeds, due to electric motor operation (Progressive). For example, “Many drivers prefer the quieter, smoother driving experience of a hybrid car compared to a louder gas engine” (Progressive). This could make the hybrid LS more comfortable in urban settings, but the gas LS’s twin-turbo V-6 is also noted for being quiet and refined at cruising speeds (U.S. News).

User Feedback and Comparisons

Reviews from sources like Car and Driver and MotorTrend provide mixed insights. For instance, the 2020 Lexus LS500h review noted that the hybrid was “slower, costlier, and only slightly more efficient than the LS500,” with an implication of less refinement (Car and Driver). However, by 2025, improvements might have been made, as U.S. News states the LS delivers a “quiet, comfy and refined driving experience” without specifying versions (U.S. News). Forum discussions, such as on [ClubLexus]([invalid url, do not cite]), often praise the LS for its smooth ride, but direct comparisons are scarce.
