What is the height of a Lexus 450h?

The Lexus 450h stands roughly 66 to 67 inches tall, with slight variations by model year, trim, and roof equipment.

Context and height expectations

The 450h designation refers to the hybrid version of Lexus's RX SUV. Exterior height is one of several dimensions that shift slightly across generations and markets. Below is a compact guide to typical heights by generation and configuration.

Note: The following figures are exterior overall heights and do not account for aftermarket modifications. Roof rails and certain aero packages can add a small amount to the total height.

• First-generation RX 450h (2009–2015): typical height around 66.0–66.7 inches (168–169 cm).


• Second-generation RX 450h (2016–2023): typical height around 66.1–66.9 inches (168–170 cm).


• Current or latest-generation RX 450h variants (2023–present in some markets): typical height around 66.0–66.9 inches (168–170 cm).

In practice, most RX 450h models sit within a narrow band, with only small deviations caused by roof rails, trim packages, or regional variants.

Height by generation

First-generation RX 450h (2009–2015)

Exterior height generally falls within the mid‑66-inch range, typically about 66.0–66.7 inches (168–169 cm).

Second-generation RX 450h (2016–2023)

Height remained similar to earlier versions, typically about 66.1–66.9 inches (168–170 cm) depending on equipment.

Current generation (2023–present in some markets)

Height stays within the same general band, around 66.0–66.9 inches (168–170 cm), with minor regional differences.

Summary: Across its generations, the Lexus 450h maintains a consistent exterior height of roughly 66 to 67 inches. For exact measurements, verify the specific model year and trim in the official specifications.

Worn CV joints. Damaged motor or transmission mounts. Wheel alignment issues.

Is the Lexus 450h bigger than 350?

No, a Lexus 450h is not inherently bigger than a 350; they are typically the same size, as the number usually refers to the powertrain, not the physical dimensions of the vehicle. For example, the RX 350 and RX 450h are the same size, but the 450h is the hybrid version of the 350. However, Lexus does offer a longer version of some models, like the RX 350L or the standard RX, which is larger than the smaller NX series, regardless of their engine/hybrid designation. 
Similar size

• Same model, different powertrain: The 450h is a hybrid version of the 350 model, sharing the same body and chassis dimensions. 
• Size difference is a model-to-model comparison: Any size difference you find is between different car lines, such as the larger RX series compared to the smaller NX series. 

Potential size differences

• Lexus RX 350L: Some models, like the RX 350L, are a "long" version of the standard RX, with a longer body and a third row of seats. 
• Different model series: The RX 450h and RX 350 are both mid-size SUVs, while the NX 450h+ is a compact SUV. The RX models are larger than the NX models. 
• Hybrid weight: The hybrid system of the 450h makes it heavier than the 350, but this does not translate to a larger exterior or interior volume. 

What is the life expectancy of a Lexus RX 450h?

A well-maintained Lexus RX 450h can last for 300,000 to 500,000 miles or more, though some owners have reported even higher mileage. Longevity depends heavily on consistent maintenance, including oil changes, fluid flushes, and other scheduled service. 
Factors that influence lifespan

• Maintenance is key: Regularly performing maintenance like oil changes, fluid flushes, and part replacements is the most crucial factor for a long lifespan. 
• Hybrid battery life: While the hybrid battery is durable, its life can be affected by factors like extreme heat or heavy usage, like regular mountain climbs. 
• Other parts: After reaching a certain mileage, other components like the suspension, water pump, or timing belt may need replacement. 

What owners report

• Many owners report easily getting over 200,000 miles with routine care, with some seeing 300,000 to 440,000+ miles on their vehicles. 
• Some owners have reported their original hybrid batteries lasting for hundreds of thousands of miles. 
• One owner on Reddit reported a 2017 model with 440,000 miles. 

How to maximize your RX 450h's life

• Follow the maintenance schedule: Adhere to the factory-recommended maintenance schedule for your vehicle. 
• Address issues promptly: Don't ignore dashboard warning lights or strange sounds. Early fixes prevent more extensive damage. 
• Drive smoothly: Avoid excessive hard braking and aggressive acceleration.
• Use high-quality parts: Opt for genuine or high-quality aftermarket parts for repairs to ensure they last.
