Audi RS5 Cabriolet: 5 Key Performance Specs & Review

The Audi RS5 Cabriolet stands out as a rare gem in the world of high-performance convertibles, combining a naturally aspirated 4.2-liter V8 engine with the practicality of four seats and Audi’s renowned quattro all-wheel-drive system. Delivering 450 horsepower and a spine-tingling exhaust note, this drop-top RS model offers exhilarating acceleration, composed handling, and refined luxury, making it ideal for enthusiasts seeking both track-day thrills and grand-touring comfort.

Powertrain Excellence: The Heart of the RS5

At the core of the Audi RS5 Cabriolet lies its 4.2-liter FSI V8 engine, a high-revving powerhouse that produces 450 horsepower and 316 lb-ft of torque. Unlike many modern performance cars relying on turbochargers, this naturally aspirated unit revs freely up to 8,500 rpm, delivering linear power with a rewarding surge past 4,000 rpm. Paired with a seven-speed S tronic dual-clutch transmission, it propels the car from 0-60 mph in approximately 4.9 seconds, with a top speed electronically limited to 155 mph (or 174 mph with the optional package).

The V8’s character shines during spirited drives, where throttle response feels immediate and precise, pulling consistently to redline. Reviewers praise its sonorous soundtrack, especially with the optional sports exhaust, which amplifies the naturally aspirated howl during open-roof cruises. This engine, shared with models like the R8, represents one of Audi’s last tributes to high-revving V8s before the shift to forced induction.

Convertible Design and Everyday Usability

The RS5 Cabriolet’s fabric roof is a highlight, folding electrically in 15 seconds (closing in 17 seconds) at speeds up to 31 mph. This three-layered cloth hood maintains cabin quietness when up and allows for quick top-down fun without compromising structural integrity significantly. Despite added weight of around 205 kg over the coupe (totaling over 4,400 lbs), the chassis retains impressive rigidity, thanks to targeted reinforcements.

Practicality surprises in this performance-oriented machine. Rear seats offer decent legroom for adults on shorter trips, and cargo space measures 380 liters with seats up, expanding to 750 liters when folded. A removable wind blocker keeps the cabin draft-free even at highway speeds, enabling conversation or enjoyment of the Bang & Olufsen sound system top-down.

• Roof Operation: Opens in 15 seconds, closes in 17 seconds up to 31 mph.
• Boot Capacity: 380L seats up / 750L seats folded.
• Seating: Four passengers with usable rear space.

Dynamic Driving: Grip Meets Grand Touring

Audi’s quattro system with torque vectoring ensures phenomenal traction, allowing the RS5 Cabriolet to achieve skidpad grip of 0.96 g, matching the coupe despite the convertible’s extra mass. Wide 275/30R20 Pirelli P Zero tires provide confident cornering without excessive tramlining, while minimal body roll keeps the car planted.

The Drive Select system offers modes like Comfort, Auto, Dynamic, and Individual, adjusting throttle, steering, transmission, and differential settings (no adaptive dampers, but a tuned RS suspension). In Dynamic mode, the car transforms into a track-capable beast; in Comfort, it glides smoothly over rough roads, proving versatile for daily use.

However, the Cabriolet’s weight is noticeable during hard braking or rapid direction changes, making it less agile than lighter rivals like two-seater roadsters. It’s not the most playful handler but excels in point-and-shoot speed and stability.

Interior Refinement and Technology

Step inside, and the RS5 Cabriolet envelops you in Audi’s signature premium cabin, with high-quality materials, supportive RS sport seats, and a driver-focused layout. The 505-watt Bang & Olufsen audio system delivers crystal-clear sound even top-down, complementing the V8’s roar. Modern touches include the MMI infotainment, though the design echoes the A5’s 2008 origins while feeling contemporary.

Nappa leather upholstery and metallic accents elevate the ambiance, with excellent build quality throughout. Visibility remains good despite the low-slung profile, and the cockpit feels both luxurious and purposeful.

Ownership Considerations: Costs and Rivals

Priced around $77,900 for 2014 models, the RS5 Cabriolet targets buyers seeking exclusivity. Fuel economy lags at around 16/24 mpg city/highway due to the thirsty V8, and maintenance for a high-performance Audi can be premium. It’s a niche choice, discontinued after 2015 without a direct successor in later generations, cementing its status as a collector’s item.

Rivals include the BMW M4 Convertible or Mercedes C63 AMG Cabriolet, but few match the RS5’s naturally aspirated V8 character and all-wheel-drive security in a four-seat package.

Pros and Cons at a Glance

• Pros: Thrilling V8 power and sound, superb grip, luxurious interior, practical for a convertible, versatile Drive Select modes.
• Cons: Heavy weight affects agility, roof operation feels dated, high fuel and ownership costs.
