2026 Lexus IS Review: IS350 V6, New Tech, And Safety

The 2026 Lexus IS stands out in the compact luxury sedan segment with its latest updates, focusing on enhanced aesthetics, interior technology, and driving comfort. This model year brings a streamlined lineup centered on the IS350, powered by a robust V6 engine, paired with rear-wheel or all-wheel drive options. While it prioritizes a balanced ride over outright speed, the IS offers premium materials and user-friendly features that appeal to those seeking everyday luxury with a sporty edge.

Key Updates for the 2026 Model Year

Significant changes define the 2026 Lexus IS, making it feel contemporary despite its mature platform. The lineup simplifies by dropping the base IS300 and high-performance IS500, leaving the IS350 as the sole offering in F Sport and F Sport Design trims. Exterior revisions include a bolder front grille, new wheel designs, and optional carbon-fiber accents, giving it a more aggressive stance. Inside, dual 12.3-inch screens dominate the dashboard—one for gauges and one for infotainment—supported by wireless Apple CarPlay, Android Auto, and a 10-speaker audio system.

• Exterior Refresh: Updated grille and headlights for a sharper look.
• Interior Tech: Larger displays with modern interfaces and ambient lighting options.
• Safety Enhancements: Lexus Safety System+ 3.0 now standard across the board.
• Trim Focus: F Sport variants emphasize handling with retuned suspension.

These modifications address previous criticisms about dated styling and tech, positioning the IS competitively against electrified rivals.

Powertrain and Performance Breakdown

At the heart of the 2026 IS350 is a 3.5-liter V6 engine producing 311 horsepower, delivering linear acceleration praised for its smoothness. Rear-wheel-drive models pair it with an eight-speed automatic transmission, while all-wheel-drive versions use a six-speed unit. Independent testing shows 0-60 mph times of 5.5-5.6 seconds, respectable for the class though not class-leading.

Handling benefits from retuned steering and suspension in F Sport trims, achieving 0.89 g on the skidpad. Braking performance is strong, with 70-0 mph stops in 155 feet. The ride quality leans comfortable, absorbing bumps better than sportier competitors like the Cadillac CT4-V.

Fuel Efficiency and Real-World Range

EPA estimates for the 2026 IS350 hover around 20 mpg city and 28 mpg highway for rear-wheel drive, dropping slightly to 19/26 mpg with all-wheel drive. Real-world testing yields about 22 mpg overall, trailing efficiency leaders like the BMW 3 Series. A full tank provides up to 400 miles of range in RWD form, suitable for long trips.

• RWD EPA: 20 city / 28 highway / 23 combined.
• AWD EPA: 19 city / 26 highway / 22 combined.
• Tested MPG: 22 mpg overall in mixed driving.

While not the most frugal, the V6’s responsive nature compensates for moderate consumption.

Interior Quality and Space Considerations

The cabin impresses with high-end materials like Nuluxe synthetic leather, soft-touch surfaces, and 64-color ambient lighting. Standard amenities include heated seats, a heated steering wheel, dual-zone climate control, and a power moonroof. The redesigned dashboard retains physical buttons for intuitive use alongside the expansive screens.

However, practicality is limited. Front seating is supportive and adjustable, but the rear is tight for adults due to the car’s compact dimensions and low roofline. Trunk capacity fares better at around 10.8 cubic feet, accommodating luggage effectively. Access to the back seats is hindered by narrow door openings and a low stance.

Safety and Driver Assistance Technologies

The 2026 IS earns top marks with a five-star NHTSA overall rating from prior testing, bolstered by Lexus Safety System+ 3.0. This suite includes adaptive cruise control, lane-keeping assist, automatic emergency braking, and a new eye-tracking driver monitor. Pre-collision systems and traffic jam assist enhance highway usability, though the eye tracker can be overly cautious.

• Automatic high beams and road sign assist.
• Pedestrian and cyclist detection.
• Dynamic radar cruise control with curve speed management.

These features make the IS a safe choice for families, despite its sporty profile.

Design and Styling Evolution

Exterior updates give the 2026 IS a more muscular appearance, with a larger spindle grille, slim LED headlights, and 19-inch wheels on higher trims. F Sport Design adds unique spoilers and badging for distinction. Critics note the front resembles some mainstream models, but the overall proportions remain sleek and athletic.

Inside, the modernized layout feels upscale, with a driver-focused cockpit. Mark Levinson audio is optional for audiophiles, complementing the standard setup.

Pricing and Trim Comparisons

Starting around $46,000, the IS350 F Sport offers strong value with its equipment list. F Sport Design adds aesthetic flair without major performance hikes. Compared to rivals:

The IS excels in ride comfort and reliability reputation over sharper-handling alternatives.

Driving Experience and Everyday Usability

For daily duties, it’s refined and reliable, with Lexus’s renowned durability. Consumer feedback praises build quality, though some note evolving standards.
