What is the difference between the Lexus RX 300, 330, and 350?
The RX 300, RX 330, and RX 350 are successive trims in Lexus’ mid‑size SUV lineup, with each step up introducing a larger V6, more power, and updated styling/tech. In short, engine displacement and performance increase from 3.0L to 3.3L to 3.5L, accompanied by shifts in transmission and features that track the era in which each model was produced.
Overview and model timeline
These badges reflect engine displacement and generation rather than a single, continuous model year. The RX 300 is the earlier iteration, the RX 330 followed as a mid‑cycle update, and the RX 350 arrived as the newer, more powerful successor with additional refinements. Each step represents a move toward greater power, smoother drivetrains, and enhanced interior technology while maintaining the core Lexus SUV character: comfort, reliability, and everyday practicality.
Powertrain and performance differences
Below is a concise comparison of engine size, approximate power, and transmission characteristics for each model. The list is focused on the core mechanical differences that most buyers use to distinguish them.
- RX 300 — 3.0-liter V6, roughly 220 hp; traditional 4‑speed automatic transmission; available all‑wheel drive (AWD) as an option.
- RX 330 — 3.3-liter V6, roughly 235–245 hp; 5‑speed automatic transmission; AWD available; improved mid‑range acceleration and newer electronics compared with the RX 300.
- RX 350 — 3.5-liter V6, roughly 270 hp; 5‑speed automatic transmission; AWD available; the most refined suspension and higher‑end features of the trio, with stronger acceleration and upgraded interior options.
Concluding the performance comparison: each step up in model name brings a larger engine and more power, along with an updated transmission and refinements in ride and technology. The RX 350 sits at the top of this trio in power and modern feel, followed by the RX 330, with the RX 300 representing the earlier baseline.
Practical differences and features
These notes summarize typical distinctions in equipment, technology, and interior amenities you’d expect across the RX 300, RX 330, and RX 350. Features could vary by year and trim level, but the general progression is clear.
- RX 300 — Entry‑level trim with simpler interior materials and fewer standard tech options; earlier design cues and wheel choices; still offers Lexus reliability and practical cargo space.
- RX 330 — Mid‑cycle upgrade with improved cabin materials, more standard equipment (such as enhanced audio or navigation in higher trims), and larger wheels/options for a more modern feel than the RX 300.
- RX 350 — Top tier of the trio with more premium interior appointments, updated infotainment/driver aids, and a more composed ride; often included more advanced safety and convenience features for that era.
Concluding the features comparison: the RX 350 represents the most refined and capable package among these three, while the RX 300 provides the earliest, more basic configuration, and the RX 330 sits in between with a balance of updated tech and still‑strong performance.
Summary
In essence, the differences boil down to engine size and output, transmission updates, and evolving features. The RX 300 uses a 3.0L V6 with a 4‑speed auto, the RX 330 switches up to a 3.3L V6 with a 5‑speed auto and more modern tech, and the RX 350 moves to a 3.5L V6 with a 5‑speed auto, delivering the strongest performance and a more premium interior. Buyers choosing among them should weigh the value of power and newer features against price and rarity of the older models in today’s market.
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.
