A fun open-air experience doesn’t need an impressive spec sheet. This quick German convertible is a hoot.
The Audi S badge means a more performance-focused model over the standard variant, built to deliver its drivers in comfort while covering miles at a rapid pace, and the S5 model has been around since 2007. When Audi chose to offer the S5 as a Cabriolet a couple years later, it replaced the S4 version that had grown seriously long in the tooth. Taking on a couple iterative updates in this generation, the S5 Cabriolet now looks sharper, and adds a bit more tech to the standard features list.
Somewhat more tame than its RS5 sibling–which I enjoyed testing last summer–the S5 model doesn’t flex big stats, but intends to deliver a solid driving experience. In its Cabriolet guise, this two-door Audi’s fun increases considerably with the element of an open-air experience. Competing with the BMW M440i convertible and Mercedes-AMG C43, the S5 has some strong rivals. With some good weather in the forecast, I happily accepted the arrival of this fun-focused drop-top Audi.
The Key Figures
Audi’s A5 is the standard form of the coupe and cabriolet model, powered by a 2.0-liter turbocharged 4-cylinder, with the S5 being the more fun-focused variant. Stuffed under the angular hood of the Audi S5 Cabriolet is a 3.0-liter twin-turbo V6 that produces 349 horsepower and 369 lb-ft of torque. The S5 Cabriolet’s output is just less than the drop-top versions of the BMW M440i and Mercedes-AMG C 43, but the Audi’s acceleration figure is nearly identical. Through an 8-speed automatic and standard quattro all-wheel-drive, the Audi S5 Cabriolet can sprint from 0-60 in 4.7 seconds on its way to a top speed of 155 MPH. EPA fuel economy estimates are 20/26/22 (city/highway/combined), which is on-par with its other German rivals.
Pricing for the base A5 Cabriolet begins at $52,200, and the quicker S5 increases the base figure to $63,400, making it similarly priced to the M440i and C 43. Thankfully Audi makes packaging easier on buyers, with three distinct trim levels that package lots of features, and I tested the top Prestige trim–an upgrade costing $8,100–which adds a Bang & Olufsen audio system, adaptive cruise control with traffic jam assist, Audi’s virtual cockpit instrument cluster, head-up display, and a stack of tech and safety features. With a stunning shade of District Green paint (a $595 option) and 20-inch wheels and summer tires fitted, this S5 Cabriolet hit a total price of $73,540 after destination.
A Composed City Convertible
While the Audi S5 Cabriolet is designed to be a blast to toss around, it’s still a luxury car at heart. Thanks to thick insulation within the acoustic top, cruising around with the roof closed makes the S5 Cab remarkably quiet. I appreciate how well the S5’s suspension smooths out the bumpiest city streets without disconnecting the driver from a responsive chassis with balanced feedback. The hint of electric assist to the steering rack makes city streets simple to tackle, and maneuvers in tight parking garages effortless.
The twin-turbo V6 may reward a spirited driver on a fun route, but keep the Audi Drive Select in the comfort mode, and the behaved operator will enjoy a daily driver that’s refined and comfortable. The turbos and exhaust tone down fun noises out of the back of the S5 Cabriolet, so if you want raunchier sounds, the dynamic drive mode is your friend. Shifts from the 8-speed Tiptronic are nearly imperceptible in the comfort mode, and sharpen ever so slightly in the dynamic drive mode.
The S5’s seats look sporty, but are definitely comfortable for long treks. The back seats are only going to carry younger kids, so don’t try to stick your adult friends behind you when driving unless they’re professional contortionists. Instead of worrying about seating capacity, I deployed the manually-fitted mesh wind deflector that covers the rear seating area to calm cabin turbulence. Dropping the S5 Cabriolet’s roof takes about 20 seconds, including operating all four of the side windows, and tucks away into a storage box that has to be manually dropped in the trunk.
Touch points are intuitive and use quality materials, and I like that there’s just enough digital instrumentation throughout the cockpit. The Audi Virtual Cockpit features a 12-inch high-resolution screen that allows for three distinct viewing modes, in addition to a simplified display for less distraction when taking night drives with the top down. As many manufacturers concede that drivers will opt for Apple CarPlay and Android Auto (both are standard with wireless connectivity in the S5 Cabriolet), Audi still delivers a great MMI infotainment system that has clear and easy software incorporated into another high-resolution display that measures 10 inches across.
Wonderful Open-Air Performance
Compared to its faster RS5 sibling I reviewed, the S5 is definitely more tame, but don’t sleep on its capabilities when you attack a twisty back road. Toggle the dynamic drive mode, and instantly feel the engine adjust its mood, with the idle rising while the exhaust tone gets throatier. Boost from the S5’s turbocharged V6 engages smoothly, delivering surprisingly quick response to help this quick convertible close long gaps between the bends. A performance car doesn’t need a massive horsepower figure to be a blast, and the S5 Cabriolet is more than competent as an open-air sportscar.
Grip from Audi’s quattro all-wheel-drive is fantastic, aided by the Dunlop Sport Maxx summer tires that are part of the 20-inch wheel upgrade. Even in its sportiest settings, the S5 Cabriolet is still composed, and does an exceptional job of concealing its 4,167-pound curb weight. I’d like a hint firmer ride in the dynamic mode, but the S5 still drives like it’s on rails. If you demand more cornering abilities from the S5, tick the $2,500 S Sport package option box to equip a sport rear differential, adaptive dampers, and cool red brake calipers, and the $1,150 dynamic steering system will add electric assistance to the steering rack to improve the S5’s steering in any condition.
Audi prepares the 8-speed transmission with shorter gear ratios for the lower gears, pairing with the twin-turbo V6’s low-end torque to enable quicker response and acceleration, but wisely fits taller ratios for the upper gears to keep revs low while conserving fuel. I played with the manual shifts with the paddles, and enjoyed the flexibility, but was still impressed with the automatic shift mapping Audi gave the S5 Cabriolet.
The Positive Points
This S5 Cabriolet is in its second generation, with Audi making significant updates in 2020. Most noticeably, the S5 Cab’s exterior was sharpened to be more impactful, with a cooler fascia with a grille that resembles the look of the one fitted to the quicker RS5 model I reviewed last year, and sports more aggressive lines from nose to tail. I can’t say enough good things about the District Green paint applied to my tester, which has pink and bronze sparkles lightly mixed in which erupt in the sunlight.
Audi does a great job of providing a cabin that’s subtle yet cool. A good blend of leather, carbon fiber, and metallic trim completes a cockpit that’s sporty yet upmarket. If you’ve been inside any Audi over the past ten years, you’ll have no trouble using every switch and button inside the Audi S5 Cabriolet, applying the “if it ain’t broke, don’t fix it” mindset effectively. The Nappa leather sport seats are not only upholding the Audi Sport lineup theme, but provide great support in their basic setup, while having great power lateral boosting to keep you planted when tossing the S5 Cab into corners.
A Couple Deductions
Making use of the convertible feature will significantly eat into the storage capacity, making my run to the airport during this test a little more complicated to stash a carry-on roller bag in the boot. When driving with the top up, the blind spot on the passenger side is significant, making you rely on the side mirrors and blind spot indicators. This is why I prefer roadsters over coupes adapted into convertibles, which make a fewer compromises. At least the top stores away completely concealed, with a hard panel covering it.
I didn’t apply too heavy a right foot during my week-long test with the S5 Cabriolet, but managed to only achieve 16 MPGs on average (versus the 21 city EPA estimate). I also feel that the drive modes Audi offers in its S and RS models could have better distinguished characteristics to provide a better overall experience. These complaints are tiny though, as the overall positives of the S5 Cabriolet far outweigh the negatives.
This Drop-Top Is Surprisingly Good
Audi does a great open-air sportscar with the S5 Cabriolet, providing plenty of fun in a great looking package. As is the case with many Audi S and RS models, the company does a fine job of blending style with a luxury car that will happily gobble up miles on longer adventures. I’d happily take road trips in the S5 Cab, and make sure to make several detours along winding routes.
If more hardcore performance is what you need, the Audi RS5 variant will tickle your fancy but sadly there’s no cabriolet version in the RS line (only offering a coupe or four-door sportback) which gives the BMW M4 an advantage against Audi and Mercedes. If a bigger stat sheet isn’t as important, the S5 Cabriolet will be a great addition to your drive, no matter if it’s to the office or along a canyon roads.
