2025 Lexus IS vs Infiniti Q50
Important Ways to Compare the Lexus IS vs Infiniti Q50 in Phoenix
If you are shopping for the best luxury sports sedan in Phoenix-- or if you just enjoy learning more about today’s sophisticated styling -- this Infiniti Q50 vs Lexus IS 300 comparison is for you.
We’ll look at design, tech toys, and performance, and we will dig into luxury car prices, value packaging, and reliability. Keep scrolling to learn more.
Price
“You can load up an IS 350 and still spend less than you would for any 3 or C,” writes The Car Connection. They also praise how Lexus has good technology for the money.
Frankly, the inflated prices of the BMW 3 Series and Mercedes-Benz C-Class demonstrate how the Lexus IS is practically unbeatable as a value package. Compared to the Infiniti Q50 in Phoenix, the Lexus IS represents real value for the money. For everything you get with a Lexus trim level, you’ll probably find yourself doing without or paying more with the Infiniti Q50.
Even the IS 500 F Performance Premium is a good value. As Forbes notes, choosing this top-drawer Lexus still means “spending far less than the European competitors.”
Long Term Ownership
The two brands have similar 4-year bumper to bumper and 6-year powertrain warranties. These are considered excellent warranties in the luxury automotive field where many brands only offer 4-year powertrain coverage.
Sweetening the deal for the IS sedan, LexusCare provides two complimentary maintenance services during the first year of purchase or lease. You won’t get that with your 2025 Infiniti Q50 lease in Phoenix.
When it comes to reliability, the Lexus has a long-standing reputation that easily exceeds the reputation for Infiniti. That reliability also translates into a solid prediction for lower maintenance costs for the Lexus.
Not only should you keep that in mind when comparing these two, but you should also consider that Lexus models generally hold their value better than other luxury cars, including the Infiniti Q50 in Phoenix.
Value Packaging
Of course, price and reliability sometimes take a backseat to the things that luxury shoppers desire. The goal is to have the most sophisticated and technologically advanced vehicle that spoils its drivers and passengers.
Here again, the Lexus IS pulls ahead. It has a more refined and luxurious interior than the Infiniti Q50 in Phoenix. While the Q50's interior may be stylish, the materials and the fit-and-finish don’t match the Lexus level of quality and craftsmanship.
Whether it’s the Lexus IS 300, 350 or 500, the luxury sports sedan comes packed with top tech toys and tools. NuLuxe and available Ultrasuede provide soft upholstery in soothing or dynamic color schemes. The long list of standards include dual-zone automatic climate controls, a power driver’s seat, advanced dash tech, and top driver assistance.
Affordable packages add a panoramic view monitor and rear cross-traffic braking. Even better, Lexus offers an intuitive parking assist to take care of the whole process for you. Get more details about Lexus IS trim levels in this 2025 luxury sports sedan review.
Proper Hot Rod
Forbes Magazine and The Car Connection (TCC) are among the reviewers who praise the high-personality IS 500. Drivers will love how it combines a top performance engine with the car’s fantastic handling and steering. TCC calls this one a proper hot rod.
With its class exclusive V8, the IS 500 generates 472 horsepower and 395 lb-ft of torque. This speedy ride can go from 0 to 60 mph in 4.3 seconds. A Torsen limited-slip rear differential, Yamaha rear performance dampers and adaptive variable suspension add to its ability to thrill the driver.
If you choose the Infiniti Q50 Red Sport in Phoenix, just know that this alternative sedan produces only 400 horsepower. This means it lags behind the IS 500 F Performance in every way.
Car and Driver sums up the Q50 sedan with these words “spunky powertrains are let down by the car's uninspiring handling and occasionally jittery ride.” They also write “nearly everything else about the sedan either creaks with age or betrays a lack of inspiration.”
Conclusion
Advantages in value packaging, long term reliability and resale value make the Lexus Is stand out. Yet it’s the refined interior, advanced tech, and balanced driving experience that makes the Lexus IS the best luxury sedan choice for Phoenix shoppers.
