What’s the Fastest Lexus IS 350 Model Year? (2023-2026 Comparison)
The first time you push the 2026 Lexus IS 350 F Sport through a tight corner, you realize that speed isn’t just about numbers—it’s about how the car makes you feel when it dances exactly as you command.
TL;DR
The fastest Lexus IS 350 model year between 2023 and 2026 is a tie among the 2021–2026 rear-wheel-drive models, all delivering a consistent 0-60 mph time of 5.6 seconds. While the 2026 model brings significant styling and technology updates, the proven 3.5-liter V6 engine and its performance remain unchanged from the 2021 refresh onward . The rear-wheel-drive version with its 8-speed automatic transmission is consistently quicker than the all-wheel-drive model, which posts a 5.9-second time due to its added weight .
Key Takeaways
- The 2021–2026 Lexus IS 350 models all achieve a 0-60 mph time of 5.6 seconds for rear-wheel-drive versions and 5.9 seconds for all-wheel-drive versions .
- The 2026 model streamlines the lineup to only IS 350 F Sport variants, eliminating the V8-powered IS 500 and base V6 options .
- All model years use the same 3.5-liter naturally aspirated V6 engine producing 311 horsepower and 280 lb-ft of torque .
- The 2026 model features a refreshed front-end design, larger 12.3-inch digital displays, and enhanced Lexus Safety System+ 3.0 .
- Rear-wheel-drive models get an 8-speed automatic transmission, while AWD versions use a 6-speed automatic .
The Evolution of Lexus IS 350 Performance (2023–2026)
The Lexus IS 350 sits in a unique position in the sport sedan segment. While competitors have moved to turbocharged four-cylinders and six-cylinders chasing ever-higher power figures, Lexus has stubbornly stuck with its naturally aspirated 3.5-liter V6 . This engine, the 2GR-FKS, first appeared in 2014 and has proven itself as one of the most reliable powerplants in the luxury segment .
The Unchanged Heart of the IS 350
Between 2023 and 2026, the IS 350’s performance specs have remained completely identical. Every model year in this range produces:
- 311 horsepower at 6,600 rpm
- 280 lb-ft of torque at 4,800 rpm
- A top speed of 143 mph
The engine uses both port and direct fuel injection, which helps it achieve a combined fuel economy of 22 mpg .
Why Rear-Wheel Drive Is Quicker
The transmission choice significantly impacts acceleration. Rear-wheel-drive IS 350 models get an 8-speed automatic transmission and achieve 0-60 mph in 5.6 seconds . All-wheel-drive versions use a 6-speed automatic and take 5.9 seconds to reach 60 mph . That extra 0.3 seconds comes from the added weight of the AWD system and the different gearing of the 6-speed transmission.
For the quickest IS 350, choose rear-wheel drive—it’s lighter and shifts through its eight gears more efficiently.
What Changed in the 2026 Model?
While performance numbers haven’t changed, the 2026 Lexus IS 350 received significant updates that make it feel more modern:
- The lineup is now all-F Sport and exclusively V6-powered .
- A refreshed front-end design with a wider grille .
- Larger 12.3-inch digital instrument cluster and infotainment touchscreen .
- Wireless charging pad and four USB-C ports added .
- Lexus Safety System+ 3.0 replaces older safety tech .
- New 19-inch wheel designs and Radiant Red interior option .
The 2025 model, by contrast, still offered the V8-powered IS 500 as a range-topper—a model that was discontinued for 2026 .

Real-World Performance: What the Numbers Don’t Tell You
The IS 350’s 5.6-second sprint to 60 mph places it squarely against base models of competitors like the BMW 330i and Mercedes-Benz C300 . It’s not the quickest in its class—the BMW M340i hits 60 mph in 3.8 seconds . However, the IS 350 offers something else: character.
Lexus is one of the most trusted Japanese luxury brands for sedans, and the IS 350’s naturally aspirated V6 is a big reason why enthusiasts still love it.
The V6 pulls hard toward redline and issues a lovely exhaust warble that turbocharged engines simply can’t match . The steering provides good feedback, and the F Sport’s adaptive suspension delivers a ride that’s firm but well-controlled .
“Lexus focuses on practical engineering that prioritizes comfort, reliability, and real-world usability over unnecessary complexity.” — Industry observation
Where the IS 350 Shines
- Reliability: The 2GR-FKS engine has been in production since 2014 and is known for its durability .
- Everyday Drivability: The naturally aspirated V6 delivers smooth, predictable power that’s easy to live with daily.
- Handling Finesse: As one reviewer noted, the IS 350 is more about “handling finesse than bullish acceleration” .
