Exploring Alternatives to the Audi Q8 55 e-tron: BMW iX xDrive50 vs Polestar 3 LR

Source: Date:

The premium electric SUV market has become increasingly competitive. Last year, options were limited to the Audi e-tron, but with Audi's announcement of the Q8 e-tron, consumers now have several choices. To evaluate the newest entry, we compare it against its key competitors: the BMW iX and the Polestar 3.

While these vehicles are classified as full-size SUVs in Europe, they are generally considered smaller mid-size options in the American market. Complicating the comparison is the fact that the BMW iX is currently the only model available for purchase. Utilizing our comparison tool, we selected three models with closely aligned specifications: the Audi Q8 55 e-tron, the BMW iX xDrive50, and the Polestar 3 LR.

Performance

Right from the start, the Audi Q8 55 e-tron appears to have a sluggish performance, despite being the newcomer in this comparison. Although we are examining the mid-level trims, even the performance-oriented SQ8 model would struggle against the more powerful BMW iX60. That said, stating that Audi is the 'slowest' among these models does not imply it underperforms—achieving 0 to 100 km/h in just 5.6 seconds is impressive for such a large vehicle. Nevertheless, the BMW iX comfortably takes the lead in performance, boasting impressive efficiency for its size as it stands tallest among the three—nearly 8 cm taller than the Polestar 3 and about 6 cm taller than the Audi.

Battery and Range

All three vehicles utilize a 400V battery architecture and feature liquid-cooled batteries. The Polestar 3 is distinct, employing a ternary battery pack (NMC) that is slightly larger than its competitors, although all three options provide more than 100 kWh of battery capacity—sufficient for both daily and extended travel. In terms of WLTP range, the BMW edges ahead, but the Polestar charges the fastest, provided access to a 250 kW DC charger, and it supports vehicle-to-grid functionality, making it a solid backup option for homes. Surprisingly, the BMW also achieves the lowest drag coefficient despite being the largest car of the three—an advantage that Polestar, with its sleek design, can only aspire to match.

Size Matters

In electric vehicles, size and weight significantly impact performance. All three cars measure nearly 5 meters in length, with the BMW being the most extensive and the Polestar the most compact. Interestingly, the Audi Q8 offers the most luggage space among the trio, as it does not have a dedicated electric vehicle platform—unlike the BMW and Polestar, which were designed as electric cars and thus should theoretically capitalize on this advantage. Thanks to its intelligent design, the Audi features the largest trunk and frunk space, while Polestar's sloping roof limits its trunk dimensions, making it less accommodating for larger items. Moreover, the BMW does not have a frunk.

Design

When it comes to aesthetics, Audi adopts the most conservative approach, while Polestar opts for a balanced design that falls between conservative and futuristic. In contrast, BMW boldly makes a statement with its unique styling. If you wish to stand out, the BMW is your best bet; Audi will blend seamlessly into any environment, whereas the Polestar will likely spark conversation.

Safety and Comfort

In this segment, consumers expect a comprehensive suite of the latest safety and comfort features. All three vehicles meet these expectations, but notably, Polestar provides the most extensive standard equipment. BMW, however, imposes extra charges for air suspension, and Audi's screens are the smallest among the three. Polestar stands out with 9 standard airbags and a driver display that may initially take some time to acclimate to due to its slim design.

Availability and Prices

While official pricing for the Audi Q8 55 e-tron is yet to be confirmed, estimations can be made based on the previous Audi e-tron model and comparisons with the BMW iX and Polestar 3. All three vehicles are priced at a premium level, rapidly reaching the €100,000 mark as options are added. Currently, the BMW iX is available for purchase, while the Audi Q8 is expected to arrive early next year, and deliveries for the Polestar 3 are anticipated by the end of next year.

Notably, the Audi Q8 is offered in two body styles—SUV and Sportback. The Q8 Sportback would provide a more equitable comparison with the Polestar 3, as both prioritize aesthetics over rear space and cargo capacity.

This comparison does not yield a clear winner; while the faster vehicles possess eye-catching designs, the more conservatively styled options come with lackluster performance. The Polestar 3 shines on paper, but it remains unavailable for another year. The Audi e-tron previously enjoyed significant popularity, and the new Q8 e-tron is poised to continue this trend. The BMW offers impressive performance, but whether this outweighs its striking aesthetics and minimal standard features remains to be assessed.
