2026 Lexus IS: 4 Key Updates, IS350 Review & Specs

The 2026 Lexus IS continues its legacy as a driver-focused luxury sedan, now streamlined to focus exclusively on the potent IS350 models in F Sport and F Sport Design configurations. This update brings sharper exterior styling, a modernized cabin with expansive digital displays, and the latest Lexus Safety System 3.0, all powered by a reliable 3.5-liter V6 engine. While rivals chase electrification, the IS doubles down on traditional performance and luxury, appealing to enthusiasts who prioritize engaging dynamics over plug-in tech.

Key Updates for 2026: What Changed?

Lexus has refreshed the IS for 2026 by discontinuing the base IS300 and high-performance IS500, leaving the IS350 as the sole powertrain option. This V6-equipped model now comes standard across F Sport trims, paired with retuned steering and suspension for better handling. The front end features a bolder grille and new lighting, while inside, dual 12.3-inch screens replace older displays for a contemporary feel. Standard features expanded to include wireless Apple CarPlay/Android Auto, a wireless charger, heated seats/steering wheel, and a moonroof.

• Exterior Refresh: New spindle grille, LED headlights, and wheel designs up to 19 inches.
• Interior Upgrades: Larger infotainment and gauge cluster, 64-color ambient lighting, Nuluxe synthetic leather.
• Safety Enhancements: Lexus Safety System 3.0 with eye-tracking driver monitoring.
• Trim Simplification: IS350 F Sport and F Sport Design only, emphasizing sporty appeal.

Powertrain and Performance Breakdown

At the heart of the 2026 IS350 is a naturally aspirated 3.5-liter V6 producing 311 horsepower and 280 lb-ft of torque. Rear-wheel-drive versions pair it with an eight-speed automatic transmission, while all-wheel-drive models use a six-speed unit. This setup delivers linear power with a refined engine note, accelerating from 0-60 mph in about 5.5-5.6 seconds according to independent tests—quick for the segment, though not the quickest against turbocharged rivals like the Cadillac CT4-V.

Handling benefits from updated suspension tuning, offering nimble everyday agility and high grip levels in emergency maneuvers. Braking is strong, with 70-0 mph stops in 155 feet and 100-0 mph in 326 feet. The IS pulls 0.89 g on the skidpad, showcasing tenacious roadholding. Top speed is electronically limited to 143 mph.

Fuel economy lags behind competitors: expect 20 mpg city/28 mpg highway for RWD (23 combined) and 19/26 for AWD, with real-world tests around 22 mpg overall. Range tops out at 400 miles on RWD models.

Interior Comfort and Technology

The cabin blends luxury with functionality, featuring soft-touch materials, physical buttons alongside the new 12.3-inch touchscreen, and a 12.3-inch digital instrument cluster. Standard amenities include dual-zone climate control, 10-speaker audio, power-adjustable seats, and a panoramic moonroof. The F Sport Design adds unique styling cues like carbon-fiber accents.

Ride quality balances sportiness and comfort, though the low-slung profile makes entry/exit tricky. Front seats are supportive, but rear space remains tight—best for shorter trips. Noise isolation is good but not class-leading, and some testers note AWD models’ center tunnel intrudes on driver legroom.

Safety and Driver Assistance

The 2026 IS earns top marks, building on the prior model’s five-star NHTSA rating. Lexus Safety System 3.0 includes pre-collision braking, lane tracing assist, adaptive cruise control, and road sign assist. A new eye-tracking camera monitors driver attention, though it can be finicky.

• Automatic emergency braking with pedestrian detection
• Dynamic radar cruise control
• Lane departure alert with steering assist
• Blind-spot monitoring and rear cross-traffic alert

Pricing and Trim Options

Starting around $46,000 for the IS350 F Sport, prices climb to over $50,000 with options and AWD. This positions it competitively against BMW 3 Series or Audi A4, offering strong value through Lexus’ renowned reliability.

Pros and Cons: Is the 2026 IS Right for You?

Strengths: Proven V6 reliability, smooth power delivery, updated tech, strong safety suite, comfortable daily driver.

Weaknesses: Dated platform, cramped rear, average fuel economy, less engaging steering than German rivals.

Ideal for buyers seeking low-maintenance luxury with sporty flair, but growing families or efficiency seekers may look elsewhere.
