2026 Mazda CX-90 3.3 Turbo S: Stamford Buyers Guide
Quick Answer: 2026 CX-90 3.3 Turbo S
Listed as "3.3 Turbo S" on Mazda's trim-comparison tools and badged "3.3 Turbo S Premium Sport" on the window sticker, this $54,140 trim is where the CX-90's retuned engine lives: up to 340 hp and 369 lb-ft on premium 91-octane fuel, versus 280 hp / 332 lb-ft on the regular-fuel trims below it. It rides on 21-inch Black Metallic wheels and adds the Mazda Driver Personalization System, which saves seat, mirror, and climate settings per driver profile. Towing stays at 5,000 lbs, same as Premium Sport and Premium Plus. EPA estimates: 23 city / 28 highway / 25 combined — the same figures as the regular-fuel tune, despite the extra 60 horsepower.
Same engine block, a genuinely different output
This isn't a software tweak that unlocks a few extra horsepower — Mazda retunes the 3.3-liter turbo inline-6 for a real jump: 340 hp and 369 lb-ft, up from 280 and 332 on the trims below. The catch, and it's worth being precise about, is that the 340-hp figure is rated on premium 91-octane fuel specifically. Run a Turbo S on regular gas and the engine won't be damaged, but it won't deliver its rated output either — the retune is built around the higher-octane fuel, not merely compatible with it. Buyers deciding between this trim and Premium Plus should factor the fuel cost difference into their math, not just the $3,870 MSRP gap.
A naming note worth flagging directly: Mazda's Brands-and-trims listings sometimes shorten this trim to "3.3 Turbo S," while the actual window sticker and build-and-price tool call it "3.3 Turbo S Premium Sport." It's the same vehicle either way — just be precise about which "Premium Sport" is meant, since the base-tune line also has a Premium Sport trim with a different engine entirely.
A trim that lives up to its own reviews
Richard Carter's review of a recent CX-90 purchase reads like it was written for exactly this kind of buyer: "Cannot speak highly enough of this dealership, its staff, and the car buying/leasing process. Ernesto and Jesse both absolute gentlemen. From the first test drive to picking up the keys to our new CX-90 a couple of weeks later I could not have asked for a more professional experience... Car is fantastic too, will recommend Riley Mazda far and wide!" Ernesto Milla is a certified sales consultant on the Riley Mazda team page. The "no stress, no pressure" tone he describes is the same Omotenashi approach that's carried the dealership since 1959, applied here to the performance end of the lineup.
Frequently asked questions
Does the Turbo S really make 340 hp?
Yes, but that figure requires premium 91-octane fuel. On regular gas, output falls back toward the base engine's 280-hp rating — the engine isn't damaged, it simply isn't tuned to reach 340 hp without the higher-octane fuel.
Why is it called "Turbo S" in some places and "Turbo S Premium Sport" in others?
They're the same trim. Mazda's own trim-comparison shorthand uses "3.3 Turbo S"; the window sticker and build-and-price tool spell out the full name, "3.3 Turbo S Premium Sport." Watch for the "S" specifically — the base-tune line has its own separate Premium Sport trim with the regular 280-hp engine.
What does Turbo S add over Premium Plus?
The retuned 340-hp engine (premium fuel required), 21-inch Black Metallic wheels, and the Mazda Driver Personalization System — for $3,870 over Premium Plus's $50,270.
Is Turbo S rated to tow more than Premium Plus?
No — towing stays at up to 5,000 lbs when properly equipped, the same figure Premium Sport, Premium Plus, and both Turbo S trims share. The extra power doesn't come with extra towing capacity.
Where can I see one in Stamford?
Current Turbo S inventory is at Riley Mazda, 75 Myrtle Ave.
The bottom line
Turbo S is the CX-90 for buyers who want a genuinely quicker three-row SUV and are willing to keep it fed on premium fuel to get there. The 340-hp tune is real, not a marketing rounding error, and the Driver Personalization System is a small but welcome touch on a vehicle that'll likely see more than one regular driver.
