New Lexus LM variant, the LM400h, expected with 300hp hybrid system

Lexus is preparing to expand its flagship LM luxury MPV lineup with a new member, the LM400h, which has been registered with the World Intellectual Property Organization (WIPO). This new variant is expected to slot between the current LM350h and LM500h models, suggesting a performance upgrade.

Japanese media reports indicate that the LM400h will adopt the hybrid system from the new generation RAV4. This system, likely the sixth-generation THS (Toyota Hybrid System), is anticipated to combine a 2.5-liter engine with an enhanced electric motor. The projected combined output is around 300 horsepower, a notable increase from the LM350h's 247 horsepower, while remaining below the top-tier LM500h's 371 horsepower.

While the performance boost is significant, the overall architecture is expected to remain similar to the LM350h, potentially blurring the market distinction between the two. Consequently, the LM400h is anticipated to be offered exclusively with an E-Four all-wheel-drive configuration. Furthermore, reports suggest that this new powertrain could also find its way into updated versions of the Lexus NX and RX models, potentially leading to NX400h and RX400h variants in the future.
