These cars have completely different body types, but they cater to the same set of buyers who want an optimal chauffeur-driven experience. So, should you choose the 2026 S-Class over the LM? Let us find out.  

Explore full specs, features and a price breakdown in our S-Class vs LM comparison.

The Mercedes-Benz S-Class combines a 3.0-litre six-cylinder petrol engine with a plug-in hybrid system that has a significant advantage of 185hp and 441Nm over the Lexus LM's 2.5-litre strong-hybrid powertrain. This is reflected in the performance figures, with the S-Class completing the 0-100kph sprint three seconds quicker than the LM. The two also differ in their drivetrain layouts: the Lexus LM's AWD system uses a rear electric motor to power the back wheels when needed, while the S-Class sends all of its power to the rear wheels, making it a rear-wheel-drive model.

On paper, the S-Class also delivers significantly higher fuel-efficiency figures. However, this is largely because its plug-in hybrid system can run on electric power alone for up to 115km, allowing it to use little to no fuel during parts of the official test cycle. By contrast, the Lexus LM's strong-hybrid system cannot be plugged in and relies more heavily on its petrol engine, making its fuel-efficiency figure less directly comparable to the Mercedes' WLTP-rated claim.

While the sizes of the driver’s display and infotainment system on both luxury cars are similar, the S-Class gets a dedicated screen for the co-driver. The Mercedes offering also has more speakers, wireless phone chargers for the rear seat passengers, and a powered sunshade for the rear windshield, over the Lexus LM. The Lexus MPV, on the other hand, offers a TV-like 48-inch rear screen with the 4-seater option, while the 7-seater version’s rear screens are the same size as those on the S-Class. The LM also offers seat ventilation on the first and second rows, but both cars offer a feature-rich chauffeur-driven experience.

Common features include powered window sunshades, a tailgate, and doors, as well as 4-zone climate control and a head-up display.

2026 Mercedes S-Class vs Lexus LM: What should you consider?

The LM's 4- and 7-seat layouts give it an edge in rear-seat practicality

Both the 2026 Mercedes-Benz S-Class and the Lexus LM are filled to the brim with features, especially for rear-seat passengers, something that is expected at their price point. However, what works in the S-Class’s favour is its powertrain, which not only offers more performance but also claims much higher fuel economy. That said, the Lexus LM’s 4-seater version is equipped with Ottoman function on rear seats, which would make it more comfortable than the S-Class, even though there may not be much difference between the two on paper. The 7-seater version gives added flexibility for buyers looking for a luxury car to move more people.
