2026 Lexus IS 350 F Sport vs IS 500: Is the V8 Worth the Extra Cash?
The first time you plant your foot in a 2026 IS 350 F Sport, you feel the smooth surge of its V6—and you can’t help but wonder what you’re missing without that glorious V8 roar.
Here’s the short answer: the choice is largely academic for 2026, because Lexus has discontinued the V8-powered IS 500. If you’re buying new, the IS 350 is your only option—and it’s a fantastic one. But if you’re considering a used 2022–2025 model, the question of whether the V8 is “worth it” comes down to what you value more: soul-stirring power or everyday sensibility.
The 2026 Reality: The V8 Is Gone
For 2026, Lexus streamlined the IS lineup significantly. The entry-level IS 300 and the range-topping IS 500 have both been discontinued, leaving the IS 350 as the sole model. This means if you walk into a dealership today, the V8 isn’t even an option.
The remaining IS 350 is powered by a 3.5-liter naturally aspirated V6 producing 311 horsepower and 280 lb-ft of torque. It’s the same engine that’s been powering IS 350s for years—reliable, smooth, and characterful in its own right.
2026 IS 350 Performance Specs
| Specification | RWD | AWD |
|---|---|---|
| Engine | 3.5L V6 | 3.5L V6 |
| Horsepower | 311 hp | 311 hp |
| Torque | 280 lb-ft | 280 lb-ft |
| 0-60 mph | 5.6 seconds | 5.6 seconds |
| Transmission | 8-speed automatic | 6-speed automatic |
| Starting MSRP | ~$47,950 | ~$49,950 |
The V6 may not pin you to your seat like a V8, but it offers something increasingly rare: linear, predictable power delivery with no turbo lag. As one reviewer put it, the engine “emits a satisfying growl that sounds better than any turbo four” when you rev it past 4,000 rpm.
The V8 Experience: What You’d Be Missing
The IS 500, offered from 2022 to 2025, packed a 472-horsepower 5.0-liter V8 under the hood. It could sprint from 0 to 60 mph in about 4.4 seconds—over a full second quicker than the IS 350.
Lexus is one of the last automakers still offering a naturally aspirated V8 in a compact sedan, making the IS 500 a future classic.
But the IS 500 wasn’t just about numbers. It was about character. The V8’s howl at high RPM, the instant throttle response, and the sense that you were driving something special—these are intangibles that specs can’t capture. It’s the kind of car that makes you find excuses to drive.
The “Sensible Sports Sedan” Argument
The IS 350, by contrast, is what many call the “sensible” choice. It delivers:
- Better fuel economy (19/27 mpg for RWD vs. the V8’s 17/25 mpg)
- Lower purchase price (about $47,950 vs. the IS 500’s ~$56,500 starting price when new)
- Lighter front end for more balanced handling
- Proven long-term reliability (200,000+ miles with proper maintenance)
The IS 350’s V6 may need to be revved to access its power, but that’s part of its charm. It rewards an engaged driver with a linear, predictable experience that’s becoming increasingly rare.
What Reviewers Say
“With the base four-cylinder and the V-8 jettisoned, the naturally aspirated V-6 is the sole engine on offer,” writes Car and Driver about the 2026 lineup. The magazine notes that while the IS 350 isn’t the quickest in its class, it offers “a naturally aspirated engine is an increasing rarity, with linear throttle response that’s becoming novel.”
The Auto Channel describes the IS 350 as “a beautifully balanced package” that’s “more about handling finesse than bullish acceleration”. In other words, it’s a car that rewards smooth driving rather than sheer grunt.
The Verdict: Is the V8 Worth It?
If you’re buying new in 2026, this debate is settled for you. The IS 350 is your only choice, and it’s a great one—especially with the refreshed interior featuring a new 12.3-inch touchscreen and improved tech.
If you’re considering a used IS 500 (2022–2025), here’s the bottom line:
- Choose the V8 if: You crave that glorious sound, instant throttle response, and a car that feels special every time you drive it. You’re willing to pay more at the pump and accept slightly higher running costs.
- Choose the V6 if: You prioritize everyday usability, lower fuel bills, and legendary Lexus reliability. You want a car that’s quick enough for real-world driving without feeling like you’re always unleashing a beast.
As one owner on the ClubLexus forums put it when considering the choice, “I like the mindless hassle free ownership of Lexus”. Both cars deliver that—just with very different personalities.
