Audi RS5 Cabriolet 450 HP Open-Top Performance Review

The Audi RS5 Cabriolet stands as a pinnacle of engineering, merging the raw power of a naturally aspirated V8 with the freedom of a convertible. This model delivers 450 horsepower through its 4.2-liter engine, paired with Audi’s renowned quattro all-wheel-drive system, making it a versatile performer on both highways and winding roads.

Powertrain Excellence

At the heart of the RS5 Cabriolet lies a high-revving 4.2-liter V8 engine, producing 450 horsepower and 317 lb-ft of torque. This naturally aspirated unit revs up to 8,500 rpm, offering a thrilling surge of power that sets it apart from turbocharged rivals. The engine’s direct injection and FSI technology ensure efficient fuel delivery, while its soundtrack—especially with the optional sports exhaust—provides an exhilarating auditory experience, particularly with the roof down.

Power reaches the wheels via a seven-speed S tronic dual-clutch transmission, which delivers lightning-quick shifts. In dynamic mode, it holds gears longer for maximum revs, enhancing the driving thrill. The quattro system, featuring a crown-gear center differential and torque vectoring, distributes power optimally, ensuring superior traction even in wet conditions.

Convertible Design and Comfort

The RS5 Cabriolet’s fabric roof folds electrically in 15 seconds when opening and 17 seconds when closing, operable up to 31 mph for spontaneous open-air drives. This three-layered hood maintains cabin quietness when up, rivaling fixed-roof cars, and includes a wind blocker for turbulence-free top-down cruising at highway speeds.

Despite its performance focus, the interior exudes luxury with Nappa leather seats, heated and ventilated fronts, and a 505-watt Bang & Olufsen sound system that performs impeccably even at high speeds with the roof retracted. The cabin layout feels modern and driver-centric, with high-quality materials throughout. Rear seats offer surprising legroom for a coupe-derived convertible, accommodating adults for short trips.

• Key Interior Features: Multifunction steering wheel, digital displays, ambient lighting, and customizable Drive Select modes.
• Practicality: 380 liters of trunk space with seats up, expanding to 750 liters when folded.
• Comfort: Draft-free cabin with wind blocker, excellent noise insulation.

Handling and Dynamics

The RS5 Cabriolet retains much of the coupe’s chassis prowess despite added weight from the convertible mechanism—around 205 kg heavier at 4,420 lbs. It achieves 0.96 g of lateral grip on the skidpad, thanks to 275/30R-20 Pirelli P Zero tires and a stiffened suspension tune.

Audi Drive Select offers modes like Comfort, Auto, Dynamic, and Individual, adjusting throttle, steering, transmission, and differential settings. Without adaptive dampers, the fixed RS5-specific setup balances compliance on rough roads with sharpness in corners. The quattro system shines in transitions, providing stability without understeer, though the car’s mass is noticeable during hard braking or rapid direction changes.

Steering is precise and weighted, inspiring confidence on twisty routes. While not as agile as lighter two-seaters, it excels as a grand tourer that hustles when pushed.

Everyday Usability and Practicality

Beyond track capabilities, the RS5 Cabriolet proves versatile for daily use. Its all-wheel drive handles inclement weather adeptly, and the smooth ride in Comfort mode suits long journeys. Fuel economy hovers around 20 mpg combined, reasonable for its power.

Rear seating adds family-friendly utility, with enough space for passengers and a boot that swallows weekend luggage. The folding roof’s quick operation ensures usability in variable climates, though sudden rain tests its 17-second close time.

Design and Visual Appeal

Audi’s muscular styling defines the RS5 Cabriolet, with aggressive lines, wide stance, and quad exhausts. Unique elements like honeycomb grille, bulging hood, and 20-inch wheels emphasize its RS badge. The fabric roof maintains sleek proportions when stowed, avoiding the bulkiness of some hardtops.

LED headlights and taillights enhance nighttime presence, while available matte finishes add exclusivity. It’s a head-turner that blends coupe athleticism with convertible allure.

Technology and Driver Aids

Modern tech abounds: navigation, Bluetooth, and the B&O system integrate seamlessly. Drive Select personalizes the experience, while safety features like stability control and multiple airbags provide reassurance at high speeds.

Pros and Cons

Who Should Buy It?

Enthusiasts craving a high-revving V8 in an open-top package will love the RS5 Cabriolet. It’s ideal for those prioritizing straight-line speed, grip, and luxury over lightweight nimbleness. As one of the last naturally aspirated Audi V8 convertibles, it holds collector appeal.
