Audi A5 Plug-In Hybrid Unveiled with S5-Level Power

Audi has transitioned from the A4 to focus on the refreshed A5 lineup, now introducing plug-in hybrid models to balance efficiency with performance. These new PHEVs come exclusively with Quattro all-wheel drive and are powered by a shared 2.0-liter turbocharged four-cylinder engine.

The entry-level A5 e-hybrid delivers a combined 295 horsepower, while the higher variant ramps this up to 362 hp, aligning with the V6-powered S5’s performance. The enhanced model accelerates from 0 to 62 mph in 5.1 seconds, just 0.6 seconds behind the S5. Although Audi hasn't released the exact weight, it's expected that the PHEV version is significantly heavier than the new S5, which weighs 4,299 pounds, due to the additional battery pack.

The new lithium-ion battery has an improved usable capacity of 25.9 kWh, representing a 45% increase from the previous A4 plug-in hybrid. Charging capabilities have also been upgraded to 11 kW AC power, enabling a full charge in approximately two and a half hours. The battery is positioned beneath the cargo floor, which may slightly reduce practicality, a common compromise in PHEV designs.

Audi estimates that the A5 sedan can achieve up to 72.1 miles on electric power alone based on the WLTP cycle, with the wagon variant likely offering a slightly shorter range due to added weight. In electric-only mode, the top speed is electronically limited to 87 mph, but activating the combustion engine increases this limit to 155 mph.

Looking ahead, Audi is anticipated to release an even more powerful plug-in hybrid version. Nearly six years after announcing an electrified RS4, Audi Sport’s former managing director indicated that the upcoming RS5 Avant would feature a PHEV setup to enhance power while reducing emissions. With the discontinuation of the A4 series, the future BMW M3 Touring competitor will be branded as the RS5 Avant, marking an interesting development.

Future Release: 2025 Audi RS5 Avant PHEV

The extended-roof RS5 has been spotted in multiple tests, suggesting a launch later this year or in 2026. While its electric range might not match the standard A5 PHEVs, it is expected to offer more robust power, potentially exceeding the 450 hp from the twin-turbo 2.9-liter V6 found in the former RS4.
