The Audi RS4 Cabriolet stands out as a rare gem in the world of high-performance convertibles, combining a naturally aspirated V8 engine with Audi’s renowned quattro all-wheel-drive system. Launched around 2007-2008 as part of the B7 generation, this model delivers electrifying acceleration, refined cruising capability, and the pure joy of top-down motoring. Despite its added weight compared to the sedan, it sprints to 60mph in approximately 4.9 seconds, powered by a 4.2-liter V8 producing 414 horsepower.

Powertrain Excellence: The Heart of the RS4

At the core of the RS4 Cabriolet is its high-revving 4.2-liter V8 engine, capable of spinning up to 8,000 rpm. This powerplant offers a broad torque curve, making it versatile for both gentle drives and aggressive sprints. Audi pairs it with a six-speed manual transmission in many markets, allowing drivers to fully engage with the mechanical symphony. The engine’s naturally aspirated design provides linear power delivery, rewarding those who explore the upper rev range with explosive performance.

Engaging Sport mode via a dashboard button sharpens throttle response and activates exhaust butterflies for a deeper growl, especially audible with the roof down. However, with the top up, added sound deadening mutes the V8 below 3,000 rpm at highway speeds, which some reviewers note as a minor drawback. Fuel economy hovers around 15-20 mpg, demanding premium unleaded and reflecting its performance-oriented nature.

Dynamic Handling and Quattro Grip

Audi’s quattro all-wheel-drive system ensures tremendous grip, even in convertible form. The RS4 Cabriolet benefits from reinforced chassis elements to counter torsional flex, maintaining impressive body control and minimal roll during cornering. Testers have clocked slalom speeds up to 70.6 mph, placing it among elite performance sedans and convertibles.

Steering is precise, though slightly less razor-sharp than the saloon due to the convertibles added mass of about 195kg (430 lbs). The ride strikes a balance: absorbent over bumps yet taut for spirited driving. Brakes are robust, providing confident stopping power. While not as track-focused as the sedan, it excels on twisty roads and delivers confidence-inspiring balance.

This table highlights the minimal performance trade-offs for the convertible’s open-air appeal.

Design and Aerodynamics: Aggressive Yet Elegant

The RS4 Cabriolet’s exterior boasts flared wheel arches, 19-inch alloys, and a subtle yet muscular stance derived from the A4 platform. With the fabric roof raised, it resembles a sleek coupe; lowered, it transforms into a poised four-seater convertible. The electrically operated roof deploys in 21 seconds, folding neatly into the trunk with minimal buffeting at high speeds.

  • Swollen arches and 19-inch wheels emphasize its performance credentials without ostentation.
  • Lengthened doors improve rear access compared to typical cabriolets.
  • Quattro badges and quad exhausts signal its RS pedigree.

Aerodynamic tweaks and wind deflectors ensure refined open-top cruising, free from excessive turbulence.

Interior Luxury Meets Sportiness

Inside, the cabin blends premium materials with driver-focused ergonomics. Standard Recaro bucket seats feature aggressive bolstering and electrically adjustable side wings that tighten in Sport mode, securing occupants during hard cornering. The layout is efficient, with high-quality fit and finish, though the navigation interface of the era feels dated by modern standards.

Rear seating accommodates adults for short trips, but space is tighter than the sedan. Options like Bose audio, iPod integration, and heated seats enhance comfort. With the roof stowed, trunk space shrinks, requiring careful packing.

Practicality and Daily Usability

For a performance convertible, the RS4 Cabriolet offers surprising refinement. Cabin noise is low with the top up, nearly matching the saloon. It’s a genuine four-seater, suitable for weekend getaways, though rear access involves tilting front seats. The near-£10,000 premium over the sedan (around $85,000-$100,000 new) reflects its exclusivity—fewer were produced than even the R8 supercar.

Maintenance demands premium fuel and regular care for the V8 and quattro system, but reliability is solid for well-maintained examples. Today, used models fetch $30,000+, appealing to enthusiasts.

Pros and Cons at a Glance

  • Pros: Thrilling V8 power and soundtrack, superb grip and balance, luxurious interior, quick roof operation.
  • Cons: Heavier than sedan affecting agility, reduced trunk space, thirsty fuel consumption, higher price premium.

Driving Experience: Roof Up vs. Roof Down

With the roof up, the RS4 Cabriolet cruises smoothly on motorways, its suspension ironing out imperfections. Push it harder, and quattro grip shines, with minimal understeer. Roof down unleashes the full V8 burble, transforming spirited drives into symphonies of revs and exhaust notes—ideal for summer blasts.

Compared to rivals like BMW M3 convertibles, the RS4 offers superior all-weather traction but trades some lightness for added weight. It’s less track-sharp but more versatile for daily use.

Ownership Considerations in 2026

Two decades on, the B7 RS4 Cabriolet remains a collector’s favorite. Seek low-mileage examples with service history to avoid carbon buildup in the V8 or differential issues. Parts availability is good via Audi specialists. Its manual gearbox and analog charm endear it to purists amid rising electrification.
