Audi A6 e-Hybrid Review (2025) : Has Audi Finally Built a Proper Plug-in Hybrid?
For years, Audi plug-in hybrids have struggled to make a lasting impression. Compared to rivals like the Mercedes E-Class PHEV and BMW 5 Series Hybrid, Audi’s previous offerings lacked both electric range and driving engagement, often feeling like afterthoughts rather than polished products.
Now, Audi is back with the all-new A6 e-Hybrid, a model that promises a serious step forward in electrified performance and efficiency. With a significantly larger battery, refined driving dynamics, and more standard tech, Audi may have finally built a PHEV worth recommending over its German competitors.
What’s New in the A6 e-Hybrid?
The new A6 e-Hybrid swaps its old TFSI e badge for a clearer name and brings a host of improvements:
- A 45% larger battery (20.7 kWh net), giving up to 65 miles of electric range (real-world 40–45 miles).
- Improved recuperation system for more efficient regenerative braking.
- Enhanced sound insulation (30% quieter) with upgraded seals.
- Standard quattro all-wheel drive and four-wheel steering for agility.
Audi claims this is the quickest A6 on sale, hitting 0–100 km/h in 6.0 seconds and running silently at up to 87 mph in EV mode.
Driving Impressions
The hybrid system is smooth, with refined transitions between petrol and electric power. The electric motor alone provides enough punch for city driving, while the combined system makes the car feel brisk and responsive.
Thanks to four-wheel steering, the A6 e-Hybrid feels much smaller than its nearly 5m length suggests. In corners, it’s agile and surprisingly flat, although the sport suspension on the S line and Edition 1 trims can feel overly harsh in town. The optional air suspension dramatically improves comfort and is highly recommended.
On longer motorway journeys, refinement is superb, making the A6 one of the most hushed premium hybrids in its class.
Inside the Cabin
The new Audi interior design mirrors the latest Q5 and A5, with wraparound digital displays and a high-tech cockpit. While premium materials like leather and Alcantara are available, there are still some disappointing plastics and gloss-black trim that feel out of place in a car priced above £60,000.
Space in the rear is decent, but the boot is a major drawback:
- Saloon: 354L (down from 492L)
- Avant: 404L (down from 503L)
Both trail their Mercedes and BMW rivals by a significant margin.
Verdict
The Audi A6 e-Hybrid is a big step forward. With its longer electric range, powerful hybrid setup, and refined driving experience, it’s finally competitive in the PHEV space. However, a small boot, firm ride on certain trims, and troubling reliability niggles prevent it from being perfect.
For the best balance, the entry-level Sport trim with standard wheels (and optional air suspension) is the sweet spot. Otherwise, if space is a priority, the BMW 530e still has the edge.
