2025 Audi S3 vs Mercedes-AMG CLA 35: the executive decision
Are you a young, talented sales rep who needs some show to match your go? Do you lust for the performance of a 'hot hatch' but require something that wouldn't look out of place on a LinkedIn post? The 2025 Audi S3 and Mercedes-AMG CLA 35 are here for you, and they both offer performance thrills, luxurious panache, and daily driver functionality–all neatly tucked beneath the guise of a blazer and tailored slacks.
These sports sedans offer near-identical performance–each is powered by some form of a turbocharged, 2.0-liter four-cylinder engine that produces just over 300 horsepower, they both send power to all four wheels, and they both use dual-clutch automatic transmissions to do so. So, since these two vehicles are so similar underneath, let's take a look at how they compare on the surface.First, we'll focus our gaze on the Audi S3–an established, well-loved compact sports sedan with vibrant aftermarket support that also makes iconic fart sounds. From its turbocharged, 2.0-liter four-cylinder engine, the S3 produces 328 horsepower–26 more than the CLA 35–and routes its thrust to all four wheels through a 7-speed dual-clutch automatic transmission.
The S3 accelerates more quickly than the Benz, with Audi claiming a 0-60 mph time of just 4.4 seconds, versus the CLA 35's claimed 4.8. Not only does the S3 have more hustle and bustle under the hood, it also has more space in the back. Comfortable clients make for happy clients, and happy clients mean you get paid.
Although the CLA 35 is officially branded as a "four-door coupe", it's certainly noteworthy that the S3 sedan beats out the CLA 35's rear seat dimensions in every vital metric, including headroom, legroom, and shoulder room. On the flip side, however, the S3 offers a notably lower cargo capacity compared to the big-boot Benz.
Just to recap–the S3 is more powerful, has a more spacious cabin, directly rivals the CLA 35, but is priced $7,400 lower than the Mercedes when plucked as a 'Premium' trim line. The 2025 Audi S3 Premium starts at $48,700, whereas the base CLA 35 commands a more hefty, $56,100 price tag. Ouch.
You might assume the stark difference in price is somehow related to equipment packaging, and that the CLA 35 might offer far more advanced technology and premium features as standard. However, even the top-trim, 2025 Audi S3 Prestige is priced lower than a CLA 35 with no optional equipment–at $54,900. So, what gives?Despite the Mercedes-AMG CLA 35's already-higher price tag when compared to the S3, there are plenty of pricey option boxes to be ticked if you'd like to personalize it even further. Once you start throwing in optional features such as genuine leather upholstery, AMG Performance Seats, AMG Aerodynamics Package, AMG Ride Control, and more, it's possible to skyrocket that MSRP well north of $75,000.
Consider the fact that Audi's even more powerful RS3 can be had for as little as $62,300, and this begins to seem almost nonsensical. What's even more concerning is that you could purchase Mercedes-AMG's very own CLE 53 Coupe, which offers a much more potent, 443-horsepower, 3.0-liter turbocharged straight-six with hybrid assist, all-wheel drive, and a claimed 4.0 second 0-60 time–for as low as $74,300.
With its turbocharged 2.0-liter four-cylinder engine, the 2025 CLA 35 AMG pumps out a healthy serving of 302 horsepower and 295 lb-ft of torque. Although that's plenty of 'get-up and go' for its size, the S3 offers more for less. And, although they both use 7-speed, dual-clutch automatic transmissions, the S3's gearbox is far more intuitive and engaging to operate when in manual-shift mode, using the available flappy paddles.
Although it may not be quite as intuitive behind the wheel, the CLA 35 is still a riot to drive, and narrowly matches the S3's preppy-but-peppy charisma. To the touch, the AMG is noticeably more 'premium' on the outside, and the fact that its dashboard isn't entirely coated in glossy black plastic and bright screens is a plus, as well.
It's not as if the CLA's added cost doesn't shine through in the details, though. There is certainly a "Mercedes-Benz" level of material quality that is closely replicated in the S3, but not quite matched. If you are obsessive compulsive about your interior spaces, the CLA 35 is a commendable option over the S3's gloss black plastic surfaces.Regardless of which you choose, these models are like the Rolex Oyster Perpetual. It may be the least expensive new Rolex you can buy, but hey, now you're in the club. You'll get all the enjoyment and practical use of a hot hatch like the Volkswagen Golf R and the Toyota GR Corolla, but with a lot more comfort and clout.
Think of these cars like Lululemon ABC Pants–you can wear them when golfing, when jogging, and when socializing out in public, but you could probably still get away with wearing them to work once in a while. The 2025 Audi S3 Sedan and Mercedes-Benz CLA 35 Coupe are kings of young-professional versatility, and it's worth noting that the BMW M235 Gran Coupe is another reasonable alternative to both, especially now that it gets a 7-speed dual-clutch gearbox for the 2025 model year.
Ultimately, the CLA 35 Coupe is a suavely-dressed seductress when compared to the S3's more conservative aesthetic, but I'm not sure if it does quite enough to justify its price tag over the Audi. The Benz may be chiseled to the core, but the S3 is certainly handsome and polite in its overall tone, and offers more car for less money to buyers who are more concerned with how it drives than with how much attention it attracts.
Would you spring for the prim and proper, mad-dashing Audi S3 Sedan, or the bold, confident Mercedes-AMG CLA 35 Coupe? Do you prefer the Audi's minimalistic interior, or are you partial towards the Benz's more vibrant environment? Let us know how you feel in the comments–we love to hear from you!

2025 Audi Q5 and SQ5 Get the Right Minor Tweaks
In the midst of a barrage of new electric-vehicle launches, Audi hasn't forgotten about its bestselling duo, the Q5 compact crossover and its medium-spicy SQ5 sibling. They're new for the 2025 model year and replace outgoing versions that are also being sold as 2025s alongside them. Even if you can't discern the differences based on model year alone, the thoroughly updated Q5 lineup sets itself apart visually and dynamically. Caught in the Headlights Following in the footsteps of other recent Audis, the Q5's sheetmetal goes from smooth to sculpted, while the lighting elements at both ends add some welcome aggression. The headlights have a more squinty look, and the taillights get the full-width treatment. View Exterior Photos Audi The LED Headlights Plus, standard on the SQ5 and upper Q5 trims, incorporate animations for startup and shutdown, while OLED taillights come on the Prestige versions of both models. The owner can select from among eight different lighting-signature designs with the fancy DRLs and taillights. And since Audi treasures its lighting-tech supremacy, the SQ5 adds projection capability to its third brake light. It lights up like normal but also casts a glow down on the hatch glass below, giving it more surface area while looking something like a nicely applied window banner with "quattro" text flanked by tapering tick marks. View Interior Photos Audi Screening Room Hop in, and more light meets your eye. Audi's Digital Stage screen setup includes an 11.9-inch screen for gauge duty and a 14.5-incher running the latest version of Audi's MMI infotainment system. The far edge of the touchscreen is curved toward the driver less for visibility and more for improved reach, a welcome touch that makes it feel less like a gaming setup. Ideally, you shouldn't have to pull your right shoulder away from the seat to touch the display, or at least that movement should be limited. This not-tall driver had no issues. The only height-related issue we had was with the SQ5's gauge screen, the top of which was cropped from our vision by the flat-brim steering wheel. An optional passenger-side display adds redundant controls and features an active filter that prevents the driver from seeing videos or games, lest they be distracted by movement on yet another screen. Aside from a slight drop in headroom, passenger-space measurements are roughly the same as before. The Q5 does see a slight growth spurt, with 1.4 inches more length, which benefits the cargo area; with all seats in place, volume increases by 1.7 cubic feet to 27.6, while the 56.9-cube max with the rear seats folded is 2.8 better than that outgoing 2025 Q5. A rear seat with adjustable tilt and 4.0 inches of fore-aft slide lets you dial in the right amount of space for people or inanimate objects. Power and More Power As before, the greatest differentiation between the standard-strength Q5 and its sportier SQ5 sibling comes in the engine room. Both use evolved versions of their previous engines, adding a smidge more output. The new Q5's sole engine offering, a turbocharged 2.0-liter four sits at 268 horsepower and 295 pound-feet, which is seven more horsepower and 22 extra pound-feet of torque than last year's step-up powertrain, which was briefly called 45 TFSI to differentiate it from the 40's 201-hp tune. The SQ5's turbocharged 3.0-liter V-6 is up 13 horses and a healthy 37 pound-feet, for totals of 362 and 406. The Q5 and SQ5 now use a seven-speed dual-clutch automatic in place of the last generation's eight-speed autos. View Interior Photos Audi If no one told us this was a dual-clutch auto, it would have been tough to suss out, as shifts were near-imperceptible and there was none of the lumpy operation that can plague these transmissions at low speeds. We found no issues with the amount or delivery of power over our varied drive of highways and twisties. The Q5's powertrain is adequate, while the SQ5's is more so, and the precise burble that comes at startup in the S model adds just a bit to the car's subtle drama. Audi claims a 5.8-second zero-to-60-mph sprint for the Q5 and a brisk 4.6 seconds for the SQ5 model. For comparison, we got bests of 5.5 and 4.8 seconds for the last-gen models, so these new estimates feel a tad conservative. On both versions, the steering sees some improvements with the rack having a more direct connection to the body, which ups the immediacy of input-to-output translation. But it still doesn't load up noticeably through tight bends, keeping the driver a bit distant from the proceedings for our liking. An air-spring suspension is standard on the SQ5 and was fitted to the Q5s we drove. It kept things comfortable and can be adjusted along with the drive modes if you're feeling frisky or want a bit more give. View Exterior Photos Audi To that end, Audi has added a new Balanced mode between Comfort and Dynamic. Balanced strikes the right, uh, chord for most driving, and we found ourselves leaving it there when not attacking some of Colorado's best roads on the way in and out of Aspen. There's still an Individual mode that lets you pick and choose your preferences for the various systems—steering, powertrain, and both suspension height and damping. A new Offroad Plus mode loosens the traction- and stability-control systems' reins compared to standard Offroad, letting you play rally driver should the opportunity arise. The newest 2025 Q5 and SQ5 are now at dealers next to the older ones, and Audi is promising tariff-free pricing on all its wares through this month. Sportback body styles are also on sale now. Pricing for the SUVs seen here starts at $53,495 for the Q5 and $66,095 for the SQ5, which is just a tad higher than before. If shopping for a compact luxury SUV, we'd pick the newer models on looks alone, so keep your eyes peeled when roaming those confusing dealer lots.
