Audi fully redesigned the Q5 and continues to sell it as a fresh, current model, while Cadillac quietly discontinued the XT4 after the 2025 model year as it pivots toward an all-electric future. That single fact hangs over any 2026 comparison, though the two are still worth stacking up, since leftover and lightly used XT4s remain on lots at tempting prices.2025 Cadillac XT4 Premium CadillacSo which one wins for 2026? On paper, the XT4 undercuts the Q5 on price and offers surprising practicality, but the Q5 is bigger, more powerful, more refined, and, crucially, still in production. Here is how they compare, and why the answer is clearer than the price tags suggest.2026 Audi Q5 Premium PlusAudiSpecs and pricingSpecificationCadillac XT42026 Audi Q5ClassSubcompact luxury SUVCompact luxury SUVEngine2.0L turbo, 235 hp2.0L turbo, 268 hpTransmission9-speed automatic7-speed dual-clutchDriveFront- or all-wheel driveStandard all-wheel driveFuel economyUp to about 30 mpgAbout 24 mpgMax cargoAbout 48 cu ftAbout 57 cu ft2026 statusDiscontinued after 2025Current, freshly redesignedStarting priceAbout $40,800About $49,000Price is where the XT4 makes its case, opening thousands below the Q5. But as the numbers and the model's fate below show, cheaper does not automatically mean smarter here.The elephant in the room: the XT4 is discontinuedTiming shapes this whole comparison. Cadillac ended XT4 production after 2025, redirecting its plant toward future electric models, so there is no true new 2026 XT4 to order. Buyers can still find brand-new leftover examples and plenty of low-mileage used ones, often at a discount, but the model has no future and no 2026 updates.2025 Cadillac XT4 CadillacAudi, by contrast, gave the Q5 a full redesign for the current generation, so it is a fresh, up-to-date vehicle with years of support and improvements ahead. For a comparison titled 'one winner for 2026,' that difference matters enormously and colors every category that follows.2026 Audi Q5 Premium PlusAudiAdvertisementAdvertisementPowertrain and performanceCadillac keeps the XT4 simple. A single 2.0-liter turbo four makes 235 horsepower and 258 lb.ft of torque through a nine-speed automatic, with front-wheel drive standard and all-wheel drive optional. It is adequate rather than quick, reaching 60 mph in around seven seconds, and the aging setup can feel a touch coarse when pushed hard.2025 Cadillac XT4CadillacAudi gives the Q5 more muscle and polish. Its 2.0-liter turbo four produces 268 horsepower and 295 lb.ft, paired with a quick seven-speed dual-clutch gearbox and standard quattro all-wheel drive, and an SQ5 adds a 362-horsepower V6 for those who want real speed. It is stronger, smoother, and more modern in how it delivers power, and its standard all-wheel drive is a meaningful everyday advantage.2026 Audi Q5 Premium PlusAudiHow they driveCadillac tuned the XT4 for comfort over sport. It rides reasonably well and is easy to place in the city, though its front-drive-based layout and older bones make it less engaging than the sharper Europeans, and the ride can turn stiff on rough roads with the sport suspension. It is a competent, relaxed cruiser rather than a driver's SUV.2019 Cadillac XT4 Premium LuxuryCadillacAudi built the Q5 to feel more planted and refined. Standard quattro gives it confident all-weather grip, its ride stays composed with available adaptive damping, and it handles with the quiet competence Audi is known for. Neither is a back-road weapon, but the Q5 is the more satisfying and more capable of the two for day-to-day driving.2026 Audi Q5AudiAdvertisementAdvertisementSize, space, and practicalityCadillac punches above its size on cargo. The XT4 is the smaller of the two, a true subcompact, yet it offers a generous 22.5 cubic feet behind the rear seats, which ranks among the best in its class, along with a comfortable, roomy front row. For urban buyers who want easy parking and surprising practicality, it delivers.2019 Cadillac XT4 Premium LuxuryAudi's Q5 is the larger, more substantial vehicle. It has more overall cargo room, up to roughly 57 cubic feet with the seats folded, more rear legroom, and a more spacious, upscale feel befitting a compact rather than a subcompact SUV. Buyers who prioritize passenger and cargo space, or plan to carry more, will find the Q5 the more roomy and flexible choice.2026 Audi Q5AudiInterior and technologyCadillac gave the XT4 a strong send-off inside. Its final update brought a large curved display measuring around 33 inches, Google built-in software, wireless smartphone integration, and a long list of standard safety features, making the cabin feel more genuinely luxurious than earlier versions. It is a pleasant, well-equipped space.2025 Cadillac XT4CadillacAudi counters with newer, more sophisticated technology. The Q5's Digital Stage display, available front-passenger screen, and richer materials give it a more contemporary, higher-end interior, and its build quality is a step above. Both are nice places to sit, but the Q5 feels more modern and premium, as its higher price implies.2026 Audi Q5AudiAdvertisementAdvertisementPrice and valueCadillac wins the value argument outright. The XT4 starts around $40,800, thousands below the Q5, and with the model discontinued, dealers are often willing to deal on remaining inventory, making it a genuine bargain for a luxury-badged SUV with solid space and updated tech. For budget-focused buyers, that is a real draw.Audi asks more, opening near $49,000 and climbing past $54,000 with popular options, but it justifies the premium with a newer platform, more power, standard all-wheel drive, and a more premium cabin. It also holds a crucial advantage the XT4 cannot: it is a current model with a future, not a discontinued one being cleared out.So which one wins for 2026?For 2026, the Audi Q5 wins, and the verdict is not especially close. It is the larger, more powerful, more refined, and more modern SUV. It comes standard with all-wheel drive, and above all, it is a current model you can order new with years of support ahead. As a forward-looking purchase for 2026, it is clearly the stronger choice.That said, the Cadillac XT4 is not without appeal for the right buyer. If you can find a new or lightly used example at a discount, it offers luxury badging, surprising cargo space, updated technology, and a lower price, which makes it a smart value play on the way out. But it has been discontinued, and for a title asking who wins for 2026, a current, superior, still-in-production Q5 takes it comfortably. Choose the XT4 only if the discount is too good to ignore; otherwise, the Q5 is the one to buy.AdvertisementAdvertisementThis story was originally published by Autoblog on Jul 24, 2026, where it first appeared in the Car Buying section.
