The Lexus IS has long been a symbol of refined performance and luxury in the compact sedan segment. As we move from the 2023 model year to 2024, Lexus has introduced subtle yet notable updates to the IS lineup. In this article, we’ll describe the key differences and similarities between the 2023 and 2024 Lexus IS models, examining specifications, features, performance, and safety to help you make an informed decision.
Specifications and Performance
Both the 2023 and 2024 Lexus IS models are powered by an Intercooled Turbo Premium Unleaded I-4 2.0L/122 engine, paired with an automatic transmission and rear-wheel drive in the base setup. They also share identical dimensions, measuring 185.4 inches in length, 72.4 inches in width, and 56.5 inches in height, with a wheelbase of 110.2 inches. Both models weigh in at 3,715 pounds, and their fuel economy remains consistent at 21 mpg in the city and 31 mpg on the highway.
If you step up to the higher trims, you can get a V-6 engine under the hood of the IS 350 or an even more powerful V-8 to power the high-performance IS 500. Fuel economy numbers suffer slightly due to the higher horsepower ratings, but you may not mind that too much if you’re looking for better performance.
Exterior and Trim Levels
The 2024 Lexus IS introduces several exciting updates, especially for the IS 500 models. One of the most noticeable changes is the addition of black outside mirrors with dark chrome trim, now standard on all IS 500 models. Additionally, a new exterior paint color option called Incognito is available, adding a fresh and sophisticated look to the lineup.
The 2024 IS 500 F SPORT Performance Premium also offers the Special Appearance Package. This includes Blue Vector exterior paint and 19-inch matte black BBS forged alloy wheels, giving the car a more aggressive and unique appearance.
Interior and Comfort
The interior of both the 2023 and 2024 Lexus IS models exudes luxury and comfort, but the 2024 IS introduces several enhancements. Both models feature standard NuLuxe-trimmed seating with 10-way driver and 8-way passenger power-adjustable front seats. F SPORT models in both years include bolstered seating with distinctive stitching. But the Special Appearance Package for 2024 IS 500 F SPORT Performance Premium adds subtle blue stitching throughout the cabin and a SmartAccess card key.
Technologically, both models come with an 8-inch touchscreen as standard, with an available 10.3-inch touchscreen for models equipped with navigation or the Mark Levinson Premium Audio Package. The multimedia system in both years includes Apple CarPlay and Android Auto compatibility.
In terms of upholstery options, both the 2023 and 2024 models provide choices such as Black, Glazed Caramel, and Rioja Red for standard models. F SPORT models offer additional colors, such as Black, Circuit Red, and two-tone White/Black trim. The 2024 model introduces new decorative ornamentation options, including Satin interior trim for the IS 500 F SPORT Performance models.
Audio enthusiasts will appreciate the Mark Levinson Premium Surround Sound audio system, available in both models, featuring 17 speakers and an amplifier delivering 1,800 watts for a 7.1 surround sound experience.
Rankings and Scores
The rankings and scores of the 2023 and 2024 Lexus IS models are remarkably similar, reflecting the continuity in design and performance. The 2024 model has an overall score of 7.4 out of 10, with category scores of 6.9 for performance, 6.6 for the critics’ rating, and an impressive 9.6 for safety, according to US News & World Report. The 2023 model scores slightly higher overall at 7.5, with 6.7 for the critics’ rating, 7.1 for performance, and the same high safety score of 9.6, based on figures from US News & World Report.
These scores indicate that both models deliver a high level of quality and safety, with only minor variations in performance and interior ratings. The slight differences can be attributed to the new features and refinements introduced in the 2024 model year.
Safety and Technology
Safety is a paramount concern for Lexus, and both the 2023 and 2024 IS models reflect this commitment. The 2024 Lexus IS benefits from the Lexus Safety System+ 2.5, which includes an array of advanced safety features. The Pre-Collision System helps detect potential frontal collisions and assists with braking, while the Dynamic Radar Cruise Control maintains a safe distance from the vehicle ahead, adjusting speed as necessary.
Additional features include Lane Departure Alert with Steering Assist, which helps keep the vehicle within its lane by providing corrective steering, and Road Sign Assist, which detects and displays road signs to keep the driver informed.
The 2023 Lexus IS, while equipped with the slightly older Lexus Safety System+ 2.0, still offers a comprehensive suite of safety features. These include the Pre-Collision System, Dynamic Radar Cruise Control, Lane Departure Alert with Steering Assist, and Road Sign Assist. Though the technology is a small step behind the 2024 model, it still provides a high level of safety and peace of mind as you drive.
2023 vs. 2024 Lexus IS Pricing and Trims
The transition from the 2023 to the 2024 Lexus IS introduces minor yet significant updates, particularly in the IS 500 models. Both models share the same engine, transmission, and dimensions, ensuring a consistent driving experience. However, the 2024 model stands out with its new exterior paint options, Special Appearance Package, and the advanced Lexus Safety System+ 2.5.
When you’re ready to buy, the decision between the 2023 and 2024 Lexus IS may come down to personal preference regarding the new features and enhancements. If you’re looking for the latest in safety technology and unique styling options, you may find the 2024 model more appealing.
However, the 2023 model remains an excellent choice, offering a similar level of luxury and performance with a lower price tag. The price of the 2024 model ranges from $41,235 MSRP for the base IS 300 trim to $64,520 for the IS 500 F Sport Performance Premium. You’ll be able to pick up a 2023 IS at a lower price.
