Hybrid Muscle: 2026 Audi RS5 Prototype Hints at Electrified Future for M3 Rival

The next-generation Audi RS5 has been spotted testing, disguised as an RS4 Avant. It's expected to debut in 2026, following the release of the new A4/A5 range in 2024.

The new RS5 will likely be offered in both sedan and Sportback body styles. It's rumored to feature a plug-in hybrid powertrain, combining a turbocharged petrol engine with an electric motor. The hybrid system is expected to produce around 500hp (373kW). This would be Audi's first hybrid RS model that isn't an SUV.

The spy shots show a wider body, larger brakes, and signature RS oval exhaust tips. The interior is expected to feature Audi's latest technology, including a large touchscreen infotainment system.

Here are some additional details about the upcoming 2026 Audi RS5:

• Body styles: The RS5 is expected to be offered in both sedan (liftback) and Avant (wagon) body styles.
• Powertrain: It's likely to feature a plug-in hybrid (PHEV) powertrain, combining a twin-turbocharged V6 engine with an electric motor.
• Performance: While exact figures aren't confirmed, rumors suggest it could produce around 500hp or potentially up to 700hp in its PHEV configuration.
• Platform: The new RS5 will ride on Audi's Premium Platform Combustion (PPC), an evolution of the current MLB Evo platform.
• Design: Spy shots reveal a more aggressive front end with a larger grille, vertical air curtains, and angular intakes. The car also features bulging fenders and a sleeker overall design.
• Interior: Expected to have a freestanding digital instrument cluster and a more modern, minimalist design.
• Technology: Likely to include Audi's latest infotainment system and advanced driver assistance features.
• Naming convention: The RS5 will replace the current RS4 Avant as part of Audi's new naming strategy, where odd numbers denote combustion engine models.
• Launch timeline: The RS5 is expected to debut in 2025 as a 2026 model, following the launch of the regular A5 lineup.
• Electric range: As a PHEV, it's expected to offer some all-electric driving capability, though the exact range hasn't been specified.

The new RS5 will compete with other high-performance luxury sedans like the BMW M3 and Mercedes-AMG C63. This model represents Audi's shift towards electrification in its performance lineup.
