Audi has introduced its latest high-performance estate, the RS5 Avant, marking a significant evolution from its predecessor, the RS4 Avant. Revealed in 2026, the new model incorporates a plug-in hybrid drivetrain for the first time in Audi’s RS Avant lineup, combining performance and efficiency in one package.

The RS5 Avant follows Audi’s updated naming convention that assigns odd numbers to hybrid and combustion engine models and even numbers to electric vehicles. Visually, the RS5 Avant retains the aggressive styling typical of Audi’s RS range, with a wide, flared body and distinctive aerodynamic elements. While the RS5 is available in both Avant and saloon forms, the lineup currently excludes the Sportback variant found in previous generations.

Under the hood, the RS5 Avant pairs a reengineered 2.9-liter turbocharged V6 with a plug-in hybrid system. The electric motor delivers 174 horsepower, complementing the combustion engine to produce a combined output of 630 horsepower. Audi reports a zero-to-60 mph acceleration time of 3.3 seconds. The hybrid system offers an electric-only range of up to 52 miles and helps reduce carbon dioxide emissions to 89 grams per kilometer. Official fuel economy stands at 72.4 miles per gallon (mpg), although real-world figures drop to around 35 mpg when operating primarily on combustion power.

Driving the RS5 Avant reveals a vehicle that feels technologically complex. It can operate in electric-only mode for urban driving before the engine engages, while a dedicated RS mode intensifies the driving experience through enhanced throttle response, amplified engine sounds, and sportier suspension settings. However, the firmest suspension mode may prove challenging on uneven roads, particularly in regions with poor road surfaces, where it can result in a bouncy ride.

The new RS5 Avant is notably heavier than its predecessor, tipping the scales at over 2.3 metric tons, an increase of more than 500 kilograms largely attributed to the hybrid components. Despite this, it maintains surprising agility and handling dynamics, supported by multiple driving modes and adjustable settings.

Inside, the cabin blends luxury with sporty design cues. Audi has equipped the car with a large central touchscreen infotainment system and a separate passenger display, along with standard 20-inch alloy wheels and Matrix LED headlights. The interior uses a significant amount of gloss black plastic, which may affect its perceived refinement. Rear seat space remains adequate, though the low ride height and sloping roofline can complicate access. A drawback is the reduced boot capacity, shrunk to 361 liters due to the hybrid battery placement, down from 505 liters in the previous RS4 Avant.

Pricing for the RS5 Avant starts at £91,300. The range-topping Performance Vorsprung trim, which adds features such as a panoramic sunroof, comes at £109,385.

Audi’s RS5 Avant demonstrates a balance between high-performance driving and environmental responsibility, achieving lower emissions and extended electric range without sacrificing much of the dynamic character expected from the RS line. While the engine’s role is less dominant due to hybridization, the model upholds Audi’s reputation for producing practical yet powerful performance vehicles.
