Audi has a habit of quietly rewriting the rules on its own cars, and the 2026 S5 is the clearest example yet. The old A5 coupe is gone. The old A5 sedan is gone. In their place sits one car with a liftback trunk and an identity that’s still settling in. So the question worth asking before you even open the door: does the new S5 still feel like an S5, or has it turned into something else wearing the badge?
First Impressions: A Familiar Face, A Different Body
Park the 2026 S5 next to its predecessor and the family resemblance is obvious. Same wide grille, same crouched stance, same sense that it’s ready to move before you’ve even started the engine. What’s changed is underneath the sheet metal. The coupe and sedan lines have merged into a single five-door body, and the trunk now opens as an electrically assisted liftback rather than a conventional boot lid.
It’s a practical upgrade dressed up as a styling choice. Loading bags, golf clubs, or a weekend’s worth of luggage is noticeably easier, and the cargo opening is wider than anything the old S5 offered. Purists might grumble that some of the coupe’s tidiness has been traded for versatility. Owners loading up for a road trip probably won’t complain.
Power, Handling, and That All-Important Quattro System
Under the bonnet sits a turbocharged 3.0 litre V6, producing 362 horsepower and 406 lb-ft of torque, paired exclusively with a seven-speed dual-clutch gearbox. Audi quotes a 0 to 60 mph time of 4.3 seconds, and in our experience, that number is conservative. On a cold morning with the right surface, the S5 gets off the line quicker than the spec sheet suggests.
What stands out more than the straight line speed is how the power arrives. There’s none of the abrupt, on-off surge you sometimes get from smaller turbo engines. The delivery is smooth and linear, which suits the car’s character better than a raw, aggressive setup would.
The standard quattro all-wheel drive system now leans rear-biased, with an electronically controlled centre differential managing torque distribution. Paired with brake-based torque vectoring, it sharpens turn-in and keeps the car settled through faster corners. In wet or wintry conditions, the traction advantage is obvious and reassuring.
Steering is precise, though it leans towards light and filtered rather than chatty. Don’t expect a running commentary through your fingertips. The S5 is happier being efficient than emotional, and depending on what you want from a sports sedan, that’s either exactly right or a small disappointment.
Inside the Cabin: Screens, Comfort, and a Few Compromises
Step inside and the cabin confirms Audi’s ongoing shift towards a digital-first interior. An 11.9 inch virtual cockpit sits ahead of the driver, while a 14.5 inch curved MMI touchscreen angles towards them from the centre console. Buyers who want it can add a 10.9 inch passenger display, letting the person in the passenger seat scroll through media or navigation without touching the driver’s screen.
Sports seats trimmed in a leather and synthetic blend come standard, along with heating for the seats and steering wheel, plus tri-zone climate control. Material quality holds up well through most of the cabin, though harder plastics still show up lower down, a reminder that even in this class, cost cutting happens somewhere.
The bigger shift is how many functions have moved onto the touchscreen. Some climate and drive-mode controls that used to have physical switches now live inside menus. It’s not a dealbreaker, and the layout stays logical once you learn it, but drivers who prefer tactile buttons for quick adjustments on the move might need a week or two to adjust.
A genuinely clever touch is the optional electrochromic roof, which can frost over in patterns at the press of a button to block out light without a traditional sunshade. It’s the kind of feature that sounds gimmicky on paper and turns out to be useful in practice, especially in Karachi’s brutal midday sun if this car ever made its way here.
Gas Mileage: Better Than the Numbers Suggest
Fuel economy was never going to be the S5’s headline feature, but it’s not the weak point some buyers might expect either. According to EPA ratings, the 2026 Audi S5 returns 20 mpg in the city and 29 mpg on the highway, with a combined figure around 23 mpg. Those numbers land in the same range as its closest rivals, the Mercedes-AMG C43 and the BMW M440i.
What’s more interesting is what happens on an actual drive. Real-world testing has recorded over 26 mpg, well above the official combined estimate, with a long-term trip average sitting around 24 mpg. Some of that gain can be chalked up to summer fuel blends, but not all of it. For a twin-turbo V6 with genuine performance credentials, that kind of real-world efficiency is a pleasant surprise.
It’s worth noting that European versions of the S5 get a mild hybrid system to help fuel economy further, a feature that hasn’t made it to the US model. Audi has said American buyers tend to dislike the stop-start behaviour that comes with mild hybrid setups, so the American S5 skips it entirely. Depending on your priorities, that’s either a missed opportunity or a sensible read of what buyers actually want.
Final Verdict
The 2026 Audi S5 isn’t chasing lap times or bragging rights. It’s built for people who want serious performance wrapped in daily comfort, without demanding they sacrifice fuel economy or practicality to get it. The new liftback body adds genuine usability, the cabin technology is a clear step forward, even with a few touch-control compromises, and the real-world mileage numbers beat what the spec sheet promises.
Is it a car for driving purists chasing feedback through the wheel? Not quite. But for buyers cross-shopping the C43, the M440i, or the CT5-V, the S5 makes a compelling, well-rounded case for itself, and that’s exactly the kind of car Audi seems to be building right now.
