Audi Q8 55 e-tron Alternatives: Comparing BMW iX xDrive50 and Polestar 3 LR

The premium electric SUV market has become increasingly competitive. Last year featured only the Audi e-tron, but with Audi's new Q8 e-tron launch, we now have several options to consider. To assess this newcomer, we’ll compare it against its primary rivals: the BMW iX and the Polestar 3.

In Europe, these vehicles are classified as full-size SUVs, but they fall into the smaller mid-size category in the American market. Moreover, the current challenge in this comparison is that only the BMW iX is readily available. Using our comparison tool, we have selected three models with specifications as closely aligned as possible: the Audi Q8 55 e-tron, the BMW iX xDrive50, and the Polestar 3 LR.

Performance

Despite being the newest contender, the Audi is off to a slower start; it is the slowest among the three vehicles. We are focusing on the mid-tier models for this analysis, as comparing the SQ8 to the iX60 would further exacerbate the disparity in speed. However, referring to Audi as the slowest does not imply it lacks performance—accelerating from 0 to 100 km/h in 5.6 seconds remains an exhilarating experience for a vehicle of its size. Notably, the BMW emerges victorious in this category, even though it holds the record as the longest and tallest among the trio, standing nearly 8 cm taller than the Polestar 3 and 6 cm taller than the Audi. This difference could suggest better efficiency, yet the BMW proves to be the more effective option regardless of size.

Battery and Range

All three vehicles employ a 400V battery architecture and utilize liquid cooling systems. The Polestar stands out by using a ternary battery pack (NMC), which is slightly larger. However, all three models come equipped with over 100 kWh of energy storage, sufficient for daily drives and longer journeys. The WLTP range is closely matched among all three, with BMW just ahead. Polestar shines in charging speed, offering rapid charging with a 250 kW DC charger, and features vehicle-to-grid capability for household backup. Surprisingly, BMW also boasts the lowest drag coefficient, despite its larger dimensions, while Polestar's aerodynamic design cannot rival BMW's efficiency.

Size Matters

In the realm of electric vehicles, dimensions—and particularly weight—play a significant role. All three SUVs measure close to 5 meters in length, with the BMW being the longest and the Polestar the shortest. Surprisingly, the Audi emerges as the storage champion, as the Q8 is the only vehicle built on a conventional chassis, unlike the BMW and Polestar, which were designed as electric cars. Audi’s clever design offers not only the largest trunk but also the biggest front storage area. Conversely, the Polestar has the least amount of trunk space and, due to its sloped roofline, cannot accommodate taller items. The BMW lacks front storage entirely.

Design

In terms of design, Audi opts for a more conservative visual approach, while Polestar finds a balance between traditional and futuristic aesthetics. BMW boldly distinguishes itself with a unique and striking design. If you aim to make an impression, BMW is the way to go; Audi favors subtlety, while Polestar is designed to engage onlookers. You can explore the visual differences among these vehicles through our picture comparison tool, which also features their interiors.

Safety and Comfort

In this segment, consumers expect cutting-edge safety and comfort features. All three vehicles excel in this regard, with Polestar offering the most extensive list of standard amenities. BMW requires additional fees for its air suspension, while Audi provides smaller screens. However, Polestar's driver display may take some getting used to due to its thin design, and it includes nine airbags as standard.

Availability and Prices

Though Audi has yet to announce official pricing, estimates can be derived from its predecessor, the Audi e-tron, allowing for comparisons with the BMW iX and Polestar 3. None of these vehicles are affordable; each nearly approaches the €100,000 mark when adding optional features. Currently, the BMW iX is the only vehicle available, while Audi is set to release early next year. Those interested in the Polestar 3 must wait, as deliveries are expected to commence by the end of next year.

It’s important to note that Audi offers two body styles, an SUV and a Sportback. The Q8 Sportback would better compete with the Polestar 3, as both prioritize aesthetics at the expense of rear headroom and cargo space.

Determining a clear winner in this comparison is challenging. While faster models may have bold designs, those with conservative appearances might offer subdued performance. The Polestar 3 looks impressive on paper, but it will not be available for another year. With the Audi e-tron’s prior popularity, the new Q8 e-tron could easily capture the same market. Meanwhile, BMW’s remarkable performance raises questions about whether consumers will overlook its less conventional look and limited standard features.
