The Audi Rs5 Cabriolet represents a unique blend of high-performance engineering and open-air driving pleasure. While winter conditions might necessitate a tire change, as was the case during our Mediterranean Alps test drive, the core essence of this convertible remains potent. Swapping the standard Pirelli P Zero tires on 20-inch wheels for Dunlop Winter SP Sport 3D rubber (275/30 R20 97W front and rear) prepared the car for colder climates, but did these changes impact the exhilarating experience expected from an RS model?
The heart of the Audi RS5 Cabriolet is its naturally aspirated 4.2-liter V8 engine. This powerhouse demands to be revved to truly unleash its potential. Although the seven-speed S-tronic dual-clutch transmission can be managed in dynamic driving, extracting maximum performance from the 444-horsepower V8 requires keeping the revs high. The engine’s peak torque of 317 pound-feet arrives between 4,000 and 6,000 rpm, and impressively sustains all the way to its thrilling 8,500-rpm redline. This specific iteration of Audi’s 4.2-liter V8 is aptly nicknamed HDZ, standing for “high revving,” a testament to its character.
However, the S-tronic transmission can present a challenge when it comes to timely downshifts. Its programming prioritizes mechanical preservation and fluid temperature management, sometimes preventing immediate downshifts if the revs are deemed too high. Drivers are then faced with either multiple paddle shifts before a downshift is permitted, or employing heavy braking before corner entry to lower revs and enable downshifting. During our test, the latter technique proved to be the more engaging approach, especially when driving solo. Notably, our test vehicle did not feature the optional 15.0-inch SGL ceramic front brake discs, but the standard lead-aluminum composite units performed admirably throughout the day.
While a six-speed manual transmission is not available in the convertible RS5, a feature missed by purists seeking ultimate driver engagement, the S-tronic offers its own brand of excitement. With Audi Drive Select set to Dynamic mode, the paddle shifts become responsive and satisfying. The electric power steering, though exhibiting some numbness, feels substantial and allows for a degree of connection to the road. Turning off traction control further intensifies the driving experience, allowing drivers to truly exploit the platform’s capabilities. For the US and Canadian markets, a rear torque-vectoring sport differential comes standard, enhancing agility and control. Regardless of the selected driving mode, the RS5 Cabriolet’s dampers and springs are firmer, and its ride height is lowered by 0.8 inches compared to the standard Audi A5 Cabriolet, providing a more focused driving dynamic.
A key point of discussion regarding the Audi RS5 Cabriolet, and RS models in general, is weight. Especially in the convertible form, the added mass moves away from the “race-inspired” ethos traditionally associated with the “RS” badge. It appears the modern RS philosophy leans towards integrating advanced technology, personalization options, and comfort features, alongside potent straight-line performance. This raises the question: should Audi consider a separate, more hardcore “RennSport” sub-brand for purists? Reducing weight in larger RS models, perhaps by 600 to 900 pounds, could unlock even greater dynamic potential. Perhaps a more direct rivalry with cars like the Nissan GT-R would then be within reach, aligning with the performance image cultivated through Audi’s DTM racing efforts.
However, acknowledging the RS5 Cabriolet as a stylish convertible rather than a track-focused coupe offers a necessary perspective. It still provides a practical trunk space of 11.3 cubic feet, exceeding the RS5 coupe’s 12.2 cubic feet (EPA rating). The robust cloth roof operates swiftly, opening in 15 seconds and closing in 17 seconds, and can now be activated at speeds up to 31 mph. With the top raised, the RS5 Cabriolet convincingly mimics the feel of a hardtop, albeit at a projected 13-percent price premium over the coupe, with an estimated base price of $79,000 upon its US arrival in June.
An essential option for any Audi RS5 Cabriolet is the sport exhaust system with black tips. This $1,000 upgrade significantly enhances the auditory experience, especially with the top down. The enhanced exhaust note transforms every corner and tunnel into an opportunity to revel in the V8’s soundtrack, often prompting unnecessary downshifts purely for the aural pleasure.
In conclusion, the 2014 Audi RS5 Cabriolet is undeniably a heavier version of the RS5, with inherent compromises in outright dynamics. However, it compensates with a substantial dose of open-top exhilaration and the intoxicating soundtrack of its V8 engine. For those seeking a blend of performance and the freedom of a convertible, the Audi RS5 Cabriolet delivers a compelling and rewarding experience.
