2020 Lexus LM I Dimensions, Size & Specs

The Lexus LM I has a curb weight of 2185 kg (approximately 4818 pounds) and a maximum weight of 2485 kg (about 5478 pounds). The curb weight refers to the vehicle's weight without passengers or cargo, while the maximum weight includes the total allowable load. This substantial weight reflects the LM's luxury features and robust construction, impacting fuel efficiency and handling dynamics. Despite its heft, Lexus engineers have optimized the LM's suspension and engine performance to maintain a smooth, stable, and comfortable ride typical of the Lexus brand.

The Lexus LM I features a ride height or ground clearance of 160 mm (approximately 6.3 inches). This height is a balanced figure for a luxury minivan, offering enough clearance for typical urban and suburban road conditions without compromising stability and aerodynamic efficiency. The 160 mm clearance helps in managing minor obstacles, speed bumps, or rough road patches comfortably, ensuring a smooth ride while maintaining the luxury feel. It is designed more for comfort and luxury than off-road capability.

The Lexus LM I, with a length of 5040 mm (198.4 inches), width of 1850 mm (72.8 inches), and height of 1895 mm (74.6 inches), generally fits into most standard residential garages. However, because it is a larger luxury minivan, some compact or smaller garages may be tight on length or width. It's important to measure your garage space, especially the door opening height and width, as the LM's height approaches or slightly exceeds typical clearance thresholds in some older garages. Overall, it fits comfortably into contemporary standard garages designed for family vehicles, though care is advised for tighter spaces.

The Lexus LM I is equipped with tires sized 235/50 R18. This tire size represents a balance between comfort, performance, and stability. The 235 mm width aids in providing good road grip and stability, important for a heavy luxury minivan. The 50 aspect ratio indicates the sidewall height is 50% of the tire width, offering a comfortable cushioning effect over road irregularities, enhancing the smooth ride expected from Lexus. The 18-inch rim diameter supports luxury styling and contributes to a balanced compromise between ride softness and handling responsiveness.

The Lexus LM I was first introduced in 2020 and replaced no direct predecessor in the Lexus lineup, as it marked Lexus's entry into the luxury minivan segment. Its closest comparator, the Toyota Alphard (which shares the platform), helped establish a benchmark for size and luxury. Thus, the LM I stands alone in Lexus's lineup with its distinct large dimensions—5040 mm long, 1850 mm wide, and 1895 mm high—designed to compete within the luxury MPV/minivan category, bridging luxury SUV comfort and minivan utility without a direct Lexus predecessor for size comparison.

Compared to other luxury minivans such as the Mercedes-Benz V-Class or the Chrysler Pacifica, the Lexus LM I measures 5040 mm in length and weighs in at 2185 kg (curb weight). It is generally longer and taller than many counterparts, offering ample interior space. For example, the Mercedes-Benz V-Class is around 5,140 mm in length but tends to be lighter, prioritizing a balance between luxury and maneuverability. The LM I’s weight and size emphasize a more plush, limousine-like luxury experience with a focus on passenger comfort, higher ground clearance, and durability, positioning it as a premium choice for buyers seeking exclusivity in the luxury minivan market.

The Lexus LM I, designed as a high-end luxury minivan, benefits from its large exterior dimensions (5040 mm length, 1850 mm width, 1895 mm height) to offer a spacious cabin that typically seats seven to eight passengers comfortably, depending on configuration. The tall height enhances headroom, while the wide body allows generous shoulder space across all rows. The vehicle is often equipped with executive seating options like reclining seats, ottomans, and enhanced legroom for rear passengers, making it ideal for VIP transport or families seeking luxury and comfort on the move.

The Lexus LM I represents Lexus’s foray into the luxury minivan segment between 2020 and 2023. Positioned as a premium MPV, it features an opulent interior, advanced technology, and smooth ride quality tailored to affluent customers seeking comfort, space, and exclusivity. The LM's design emphasizes refined luxury with high-quality materials, extensive passenger amenities, and cutting-edge safety features. Its size and weight support a stable and calm driving experience. It appeals particularly to markets valuing luxury people movers, such as Asia and the Middle East, where spaciousness and comfort are paramount.

The Lexus LM I, being a large luxury minivan with a curb weight of 2185 kg and a maximum laden weight of 2485 kg, naturally consumes more fuel than smaller vehicles. The vehicle’s size (5040 mm long and 1850 mm wide) and weight mean that engineers must balance power delivery with fuel economy. While Lexus typically offers hybrid variants and efficient engine technology, the LM’s primary focus is on luxury and comfort rather than fuel savings. Thus, fuel efficiency may be moderate compared to smaller SUVs or sedans. Buyers affected by fuel economy concerns should weigh the benefits of luxury and space against potentially higher operating costs.
