The Lexus LS was created in 1989 to beat the Mercedes-Benz S-Class, and it still offers a compelling alternative: exceptional build quality and reliability, beautiful Japanese craftsmanship (such as hand-pleated door trim and Kiriko glass), and a hybrid option. The S-Class offers more rear space, more advanced technology, a wider range of engines, more chauffeur-focused features and a stronger presence in professional chauffeured service.

Rear comfort

The LS offers an Executive package with a reclining rear seat, ottoman and shiatsu-style massage. The S-Class offers similar features plus more rear room overall, rear airbags and a more extensive set of rear controls.

Craftsmanship

Lexus’s interiors showcase Japanese craft: pleated fabrics, cut-glass trim, and artisan-inspired materials. The S-Class focuses on luxurious leather, wood and dramatic lighting.

Reliability and ownership

Lexus consistently ranks near the top of reliability surveys, and its dealer service is renowned. The S-Class is more complex, but professional fleets manage that complexity with rigorous maintenance.

Verdict

The LS is a wonderful, dependable luxury sedan and a smart choice for owners. For chauffeured passengers, the S-Class remains the benchmark. Read the Lexus LS 400 story and why chauffeurs choose the S-Class.

Technology compared

The S-Class offers an OLED central display, an augmented-reality head-up display, rear-axle steering and, in approved regions, Level 3 Drive Pilot. The LS offers a well-integrated infotainment system, Lexus Safety System+ driver assistance and, on some versions, advanced hands-free traffic-jam assistance in certain markets. The S-Class is the more technologically ambitious car; the LS focuses on proven, reliable technology.

Hybrid efficiency

The LS 500h is a full hybrid that can move silently at low speeds in city traffic — a pleasant trait for passengers in Manhattan’s stop-and-go. The S-Class counters with 48-volt mild hybrids across the range and the S 580e plug-in hybrid, which can cover many city trips on electricity alone. Read hybrid vs plug-in vs electric.

Who each suits

  • Choose the LS if you drive yourself most of the time, value reliability and craftsmanship, and want a calm, understated luxury car.
  • Choose the S-Class if you are regularly driven, want the most rear-seat features, or need a car that is recognized worldwide as the executive standard.
