What is the difference between RX270 and RX350?

The RX350 is the more powerful, larger-engine variant, while the RX270 uses a smaller engine and typically emphasizes efficiency. Availability and exact specs vary by market and model year.

Across regions, the RX270 name appeared in some markets as a 2.7-liter variant of Lexus' RX crossover, whereas the RX350 denotes the 3.5-liter V6 version. While both belong to the same RX family, they differ in power, features, and regional availability. This article breaks down the key distinctions, market context, and buying tips for prospective owners or researchers.

Engine and Performance

Powerplant overview

The RX350 is built around a larger 3.5-liter V6, delivering stronger acceleration and higher on-road pace. The RX270 uses a smaller 2.7-liter engine, which typically offers better fuel economy but less power and a slower initial punch. Exact horsepower and torque figures vary by year and market.

Here are the core differences you’re likely to notice when comparing the two models:

• Engine displacement: 3.5 L V6 for RX350 vs around 2.7 L for RX270


• Power and acceleration: RX350 generally faster off the line and more capable at highway speeds


• Fuel economy: RX270 usually more efficient due to the smaller engine


• Drivetrain options: both can be found with front- or all-wheel drive depending on market and year


• Transmission pairing: automatic transmissions in both, with RX350 variants often receiving newer tuning in later years

In practice, buyers often note that the RX350 provides a more confident highway experience and potential for heavier loads, while the RX270 suits daily commuting with lower running costs.

Equipment, Comfort, and Technology

Trims and in-cabin features

Beyond powertrains, the RX350 variants typically offered more premium materials and tech options, especially in later years. The RX270 variants commonly focused on affordability, though equipment levels can vary by market and year. The exact feature set depends on the specific trim and regional packaging.

Representative differences you might encounter across markets and model years include:

• Interior materials and seating: higher-grade trims more common on RX350


• Infotainment and navigation: newer tech more frequently bundled with RX350 in later years


• Comfort amenities: features such as multi-way power seats, memory settings, and premium audio more common on RX350


• Safety and driver-assistance: depends on year; newer RX350 builds often incorporate more advanced safety tech

As with powertrains, regional equipment packages vary widely. Always verify the exact spec sheet for the individual vehicle you’re considering.

Market Availability and Model-Year Context

Regional rollout and naming

The RX line has evolved differently by region. In the United States, the line progressed from RX300 to RX330 and RX350, with the RX270 badge not widely used in the US market. In some other markets, particularly in the early 2000s, there were regional variants of the RX family that used the RX270 designation. The RX350 has been the more globally common variant in many regions, especially from the mid-to-late 2000s onward.

Because model-year updates and regional naming conventions vary, it’s important to verify the exact engine, transmission, and equipment on any used vehicle via the VIN and documentation. The general rule is that RX350 carries the larger engine and often more premium equipment, while RX270 represents a smaller-engine option with differing equipment levels depending on year and market.

What to Look For When Buying

Practical buying pointers

When evaluating used RX270 and RX350 models, consider these practical checks to avoid pitfalls and identify the best value:

• Verify engine and transmission condition with a trusted mechanic; the RX350’s 3.5L V6 is robust but older examples can show wear or cooling-system issues


• Review service records for timing belt/chain maintenance, fluid changes, and any past recalls


• Check for common wear items on the RX platform, such as suspension components, brake wear, and axle seals


• Inspect interior electronics and infotainment units, which can be costly to repair in older trims


• Compare market-specific trim levels to understand what features are included and what may need after-market additions

Because regional variants and model years differ, a careful VIN-based history and a thorough pre-purchase inspection are essential to ensure you know exactly what you’re buying.

Summary

In essence, the RX350 offers more power, more premium equipment in many markets, and stronger highway performance, while the RX270 emphasizes a smaller engine and potentially better fuel economy with varying equipment by market. Availability and exact specs depend on year and region, so always verify the specific vehicle’s documentation and conduct a thorough inspection before buying.

How long will a Lexus RX 270 last?

around 200,000-250,000 miles
You can expect a typical Lexus RX to last around 200,000-250,000 miles, with the high mileage point resting around 200,000 miles and good mileage sitting at 150,000 or more.

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 RX 270 and RX 350?

What the RX270 lacks, though, is the added muscle and better traction of the RX350, which is equipped with a 3.5-litre V6 as well as all-wheel drive. The RX270's 2.7-litre inline-4 musters a decent 187bhp and 252Nm, but these figures are 90bhp and 94Nm lower than what the RX350 produces.

What does RX mean in Lexus RX 350?

The RX model name stands for Radiant Crossover. The word Radiant represents the bright new future Lexus envisioned at the car's launch at the start of the Millennium. The model was the first sports utility vehicle that marked a Crossover point between a luxury saloon and an off-roader.
