How much longer is the RX 350L than the RX350?
In most model years, the RX 350L is about four inches longer than the RX 350, largely to accommodate the third-row seating and a longer wheelbase.
That extra length translates to more interior space and a different footprint on the road. The difference is generally consistent, though it can vary slightly by year, trim level, and market specifications.
Why the length difference exists
The RX 350L was designed to expand interior capacity without a complete redesign of the RX platform. By extending the wheelbase and overall length, Lexus created a usable third-row seat and more rear interior space while preserving the familiar exterior styling of the RX line.
How the length gap typically breaks down
Before examining the specifics, note that the exact inches can vary by model year and configuration. The following points capture the common pattern shoppers should expect when comparing models.
- The additional length comes primarily from a longer wheelbase and rear overhang to fit a third-row seat.
- The overall length difference is generally around 4 inches (roughly 10 cm).
- In some years or trims, the gap may be reported slightly differently (roughly 3.5–4.3 inches) due to minor design tweaks or measurement conventions.
Across typical model years, the RX 350L remains about four inches longer than the RX 350, with small year-to-year variations depending on trim and options.
Practical implications
The longer RX 350L offers more interior space and easier access to the third row, which can be a decisive factor for families or frequent passengers. However, the increased length can slightly affect maneuverability in tight spaces and reduce cargo space behind the third row when it is in use. Prospective buyers should weigh interior flexibility against parking and city driving considerations.
Model-year notes
Early generations (2016–2019)
The RX 350L established the approximately four-inch length increase to accommodate the third row and a longer wheelbase, setting the baseline for this model variant.
Recent generations (2020–2024)
The core geometry remains, with minor trim- and option-related variations. The four-inch gap persists as the general guideline, with small fluctuations by year and market.
Summary
Overall, the RX 350L is roughly four inches longer than the RX 350 across most model years, driven by a longer wheelbase and the addition of a usable third-row seat. For buyers, the key takeaway is that the RX 350L provides more interior space at the cost of a slightly larger exterior footprint.

What year to stay away from Lexus RX 350?
Years to avoid for the Lexus RX 350 include 2007, 2008, 2010, 2016, and 2017 due to common problems like oil leaks, engine issues, brake failures, and faulty sensors. The 2010-2012 models are particularly prone to a ruptured oil cooler line that can cause engine failure, while the 2007-2009 models had issues with cracking dashboards and a faulty brake master cylinder. The 2016 and 2017 models saw recalls related to airbags and issues with rain sensors, notes CoPilot.

Years to avoid and why
- 2007–2009: These models are known for cracking dashboards and a faulty brake master cylinder that can lead to brake failure.
- 2010–2012: A common and severe problem with these years is the oil cooler line, which can rupture and lead to engine failure.
- 2016–2017: The 2016 model year had airbag recalls and was the first year of a new generation, which can lead to early bugs. The 2017 model had issues with the rain sensor and wipers, in addition to having its own airbag recalls.
What to look for instead
- 2011–2015: These models generally have fewer issues, with the 2013–2015 models in particular being noted as more reliable.
- 2018–2022: Models from these years are considered more reliable, especially those with the redesigned exterior.
- 2020–2022: These are considered among the most reliable years, with the 2020 model year being a good choice.

What is the difference between the Lexus RX 350 and RX 350L?
The main difference is that the RX 350L has a longer body to accommodate a third-row seat and can seat up to seven passengers, while the standard RX 350 has two rows and seats five. Other differences include slightly different cargo space, with the RX 350L having less room behind the third row but more total volume with the seats folded, and a slight trade-off in fuel efficiency for the L model. The RX 350L also includes some features as standard that might be optional on the regular RX, such as heated front seats and three-zone climate control.
