What is the difference between a Lexus RX 350 and 350L?
The RX 350L is the longer, three-row variant of the RX 350, offering seating for up to seven; the standard RX 350 is a two-row SUV for five passengers. Powertrains are largely shared, but the 350L weighs more and typically commands a higher starting price.
The main difference is seating and space. This article breaks down how the models differ in interior layout, dimensions, cargo capacity, performance, technology, and ownership considerations to help you decide which RX fits your needs.
Seating and interior layout
Below are the key differences in how people sit and how the cabin can be configured.
- Seating capacity: RX 350 is a two-row, five-seat layout; RX 350L adds a third row for up to seven passengers, depending on trim and configuration.
- Second-row options: RX 350 typically uses a second-row bench seat; RX 350L offers the option of captain’s chairs on the second row in some trims, with the bench available on others.
- Third-row usability: The RX 350L’s third row is meant for occasional use and is most comfortable for children or shorter trips; the RX 350 does not have a third row.
- Access to the third row: The longer wheelbase of the RX 350L provides easier access to the third row, though space remains limited compared to many true 3-row SUVs.
The two-row RX 350 emphasizes a roomy five-passenger cabin with a larger second-row area for luggage and gear, while the RX 350L prioritizes passenger versatility and flexibility at the cost of some rear cargo practicality when the third row is in use.
Dimensions, cargo space, and practicality
These points explain how overall size and storage differ between the models.
- Overall size: The RX 350L is longer and has a longer wheelbase to accommodate the third row; the RX 350 remains more compact in footprint.
- Cargo behind the third row vs. behind the second row: With the third row folded, the RX 350L offers expanded cargo space, but with the third row in use, cargo space is significantly reduced compared to the RX 350.
- Rear seating footprint: The third row in the RX 350L reduces available cargo space when in use, even if luggage remains possible with smaller items.
- Practicality in daily use: If you frequently carry seven passengers or need occasional third-row seating, the RX 350L provides more versatility; if you mostly carry five and cargo, the RX 350 may feel more practical.
In short, the RX 350L trades some cargo capacity and a bit of interior space behind the rear seats for the extra seating flexibility of a third row and a longer wheelbase.
Performance, efficiency, and technology
Here’s how the driving experience and tech compare between the two models.
- Powertrain: Both models share the same 3.5-liter V6 and an 8-speed automatic transmission, producing comparable horsepower and torque figures.
- Drivetrain options: All-wheel drive is available on both, with similar handling characteristics tailored to their size and weight.
- Efficiency: The RX 350L typically weighs more due to the extra seating, which can lead to a modest decrease in highway and city mpg compared with the two-row RX 350.
- Technology and trim differences: Features vary by year and trim, but both models commonly include Lexus Safety System+ as standard and offer similar infotainment and driver-assistance options across generations.
Performance feels similar on the road, with the RX 350L’s extra weight mainly affecting cargo versatility and fuel economy rather than outright acceleration. Trim-level choices influence interior tech and comfort amenities more than power output.
Pricing and ownership considerations
Consider cost and long-term ownership when choosing between the two.
- Pricing: The RX 350L typically carries a higher starting price than the RX 350 due to the added seating and extended chassis.
- Used-car value: Depending on age and condition, the three-row RX 350L can hold different resale value than the two-row RX 350; supply, demand, and mileage play major roles.
- Availability: In certain model years, the three-row RX 350L was offered as a distinct option; later generations may reorganize seating and trim levels, so availability can vary by market and year.
For buyers prioritizing passenger capacity and practicality, the RX 350L represents a higher upfront investment with the benefit of extra seating. Those who need maximum cargo space with five passengers may prefer the RX 350.
Summary
In essence, the RX 350 and RX 350L share a common powertrain and many features, but they serve different needs: the RX 350 is the standard two-row, five-seat model with more cargo room behind the second row, while the RX 350L stretches the wheelbase to add a third row for up to seven passengers, trading some rear cargo space for versatility. Your choice should hinge on how often you need third-row seating versus how much cargo you typically carry, along with your budget and preferred trim level.
