The Lexus LM is equipped with a full hybrid powertrain similar to the one found in the NX and RX models. It combines a 2.5-litre four-cylinder Atkinson-cycle petrol engine with two electric motors, resulting in a combined power output of 247bhp and 176lb ft. Although not particularly fast, the LM still offers a decent straight-line performance that resembles a car rather than a van. It can accelerate from 0-62mph in 8.7 seconds (or 9.1 seconds for the FWD version), which is more than adequate for a vehicle of its size.
Despite its substantial size, the LM is surprisingly maneuverable. It features a large glasshouse and HGV-like mirrors that provide excellent visibility from all angles. Additionally, it comes with a range of parking aids and a tight 11.6-meter turning circle, which makes navigating tight spaces like airport VIP drop-off ramps or the Savoy Hotel circle less challenging.
One drawback of the LM is its CVT (Continuously Variable Transmission). While the CVT helps minimize body roll and provides a smooth acceleration experience, it produces an unimpressive sound during uphill acceleration or overtaking maneuvers, which detracts from the luxurious feel of the vehicle. The LM is a heavy vehicle, weighing almost three tonnes, and the engine’s strain is evident in the cabin when under load.
However, at lower speeds in urban areas, the LM switches seamlessly between its electric motor and petrol engine to maximize efficiency and comfort. It also features an impressive low-speed EV mode, allowing it to achieve nearly 40mpg on the WLTP combined test cycle. This is a remarkable feat considering its imposing size and suboptimal aerodynamics.
In conclusion, the Lexus LM offers an appealing combination of features, even though it may seem unconventional for a luxury car. While some may associate luxury motoring with large saloons and SUVs, the LM stands out as a credible and innovative alternative. It can rival models like the Mercedes-Benz S-Class and the Bentley Bentayga, especially when it comes to rear-passenger comfort and enjoyment.
