2026 Lexus IS 350
for Riverside, CA
For over 25 years, the Lexus IS has defined the compact luxury sports sedan segment. For the 2026 model year, Lexus has dramatically streamlined the IS lineup to focus entirely on what drivers want most: uncompromised V6 performance.
The 2026 Lexus IS 350 is now the exclusive core of the IS family, eliminating the previous four-cylinder and V8 options to guarantee that every new IS delivers the thrilling "Lexus Driving Signature." Lexus of Riverside is proud to introduce this restyled, hyper-focused sports sedan to Inland Empire drivers who demand luxury, reliability, and exhilarating power in a single package.
A Riverside Driver's Perspective
Navigating Southern California requires a vehicle that can effortlessly transition from gridlocked commutes to wide-open mountain passes. The 2026 Lexus IS 350 is engineered for exactly this duality.
When you are merging onto the 91 freeway during rush hour, the standard 3.5-liter V6 engine provides instant, confident acceleration to match the flow of traffic. The redesigned cabin and updated 12.3-inch multimedia system turn a stressful commute into a refined, connected experience.
When the weekend arrives, the IS 350 transforms. Taking the twisting, elevated roads up to Mount Rubidoux or carving through the canyons toward the San Bernardino National Forest reveals the true nature of the Lexus Driving Signature.
The rigid chassis and sport-tuned suspension keep the sedan planted, while the available All-Wheel Drive system ensures you maintain total traction on unpredictable mountain roads, even when properly equipped for sudden elevation weather changes.
Pure V6 Performance and Capability
Lexus has removed the guesswork from the 2026 IS powertrain lineup. Every model leaving the factory floor is now an IS 350 equipped with a naturally aspirated V6. This means you no longer have to upgrade to experience premium power.

Frequently Asked Questions
Is the Lexus IS 300 or IS 500 available for 2026?
No. For the 2026 model year, Lexus has discontinued the 4-cylinder IS 300 and the V8 IS 500. The lineup has been streamlined to exclusively feature the V6-powered IS 350. This ensures every IS driver in Riverside receives the 311-horsepower performance standard.
Do I need All-Wheel Drive for driving in Southern California?
Rear-Wheel Drive is ideal for the dry climate and paved roads of Riverside. However, All-Wheel Drive is highly recommended if you frequently travel to Big Bear or Lake Arrowhead where road conditions can change rapidly.
What is the benefit of the F SPORT Handling Package?
This package is for drivers who want a more "active" feel. The Adaptive Variable Suspension (AVS) adjusts damping in real-time to prioritize either comfort or sportiness, while the Torsen Limited-Slip Differential on RWD models provides significantly better traction when exiting corners.
How fast is the 2026 Lexus IS 350?
The 2026 IS 350 RWD reaches 0-60 mph in 5.9 seconds. The AWD version is slightly quicker at 5.7 seconds due to its off-the-line traction, providing plenty of power for the freeway on-ramps around Riverside.
