The consensus is that the 2010 Audi S5 maintains Audi's stunning level of interior quality, though there are some quibbles.
In reviews read by TheCarConnection.com, the front seats are supportive and hold their passengers in place without being uncomfortable, unlike the rear seats, which are merely tight and completely at a loss when asked to handle adult legs. The front sport seats are upholstered in what Audi calls "Silk Nappa leather," and they're highly contoured for grippy comfort. Car and Driver praises the "highly adjustable seat" and a "tilting-and-telescoping steering wheel" that offer the driver a wider range of options. However, the "beltline is high," causing you to feel "a little buried in the car." On the 2010 Audi S5 Cabriolet, Car and Driver says that "two types of front seats will be offered," including "aggressive sport seats" and optional, "slightly less aggressive thrones" with the comfort package. Cars.com notes "the driver and front passenger get leather sport seats that have large side bolsters on both the bottom cushion and backrest. The seats proved comfortable for the duration of my week with the car and came in handy during aggressive driving." MyRide.com also speaks of the comfort of the front seat area, citing it as one of the "selling points" of the vehicle; the "generous amounts of overall passenger room" is sure to capture serious attention.
Cars.com says, "There's room for two in the back of the S5. Despite the car's low-slung shape, there's tolerable space for two adults here, and more than enough for kids." For a coupe, the S5 has a comfortable backseat, states Car and Driver, though "a six-footer will be touching knees and head when sitting behind another six-footer." The Cabriolet gets a similar rear-seat treatment, which prompts Car and Driver to report that the "back seat is strictly a two-passenger affair but is spacious for a convertible in this class and tolerable for adults." However, getting in and out of the car is rather easy due to the "conveniently located seatback-mounted switches to move the power seats fore-and-aft." Edmunds agrees, though noting "taller folks will find under-thigh support and legroom somewhat lacking." MyRide.com stresses that it is important to "park with care." The S5's long doors make it "a bit difficult to enter and exit in tight spaces."
Fancy features aside, the 2010 Audi S5 has something many sport coupes lack: plenty of room for two sets of weekend luggage. Cars.com feels "the S5's trunk is rather large, at 16.1 cubic feet. That compares to the BMW 3-Series' 11.1-cubic-foot trunk and the Infiniti G37's 7.4-cubic-foot cargo area." Edmunds again concurs: "The trunk offers 16 cubic feet of cargo capacity (large for a sedan, let alone a coupe), and the rear seat flips down to accommodate more, if need be." You'd be crazy to schlep home lumber in this pricey vehicle, but you could easily do so. While most convertibles in this class feature space-sucking hardtop convertibles, the 2010 Audi S5 Cabriolet gets a cloth roof, which bestows the S5 Cabriolet with a respectable amount of versatility. Cars.com says the "move allows for 11.3 cubic feet of storage volume with the top down," while some of the biggest competitors-like the Volvo C70-make do with just "6 cubic feet of trunk space with the top down." In addition to the spacious trunk, Car and Driver points out that Cabriolet's "50/50-split back seat also folds forward, swelling cargo capacity to 26.5 cubic feet."
Quality is typical for Audi: tightly constructed and tasteful. The leather is "finely stitched," the fit and finish are "impeccable," and the aluminum trim is real, making for an impressive cabin of obvious quality. Cars.com appreciates how the S5's "Silver-colored trim encircles the gauges and dash vents, and high-end materials like aluminum, carbon fiber and wood are available in addition to the standard piano black accents." Car and Driver reports, "Mucho aluminum trim has been smattered about, and we're particularly fond of the A5's take on Audi's 'teardrop' gauges."
Aside from the obvious security advantage, hardtop convertibles typically afford a much quieter ride than cloth tops, but reviews read by TheCarConnection.com show that the Audi S5 Cabriolet matches nearly any car in the class for noise levels. Popular Mechanics says that the S5 Cabriolet "comes standard with Audi's Acoustics Roof, which is said to reduce noise levels ‘almost to the sedan level.'" Car and Driver has no trouble agreeing with that statement, proclaiming "with the Bang & Olufsen stereo cranked, wind noise isn't even an issue."
