Xiaomi is testing longer version of the SU7

Following the very successful release of its first two models Xiaomi is already plotting its next chapter. Fresh spy shots from China show the company isn't resting after the launch of its SU7 sedan and the YU7 SUV. Instead, it is developing a new, longer version of the electric sedan.

Camouflaged prototypes seen undergoing road tests reveal a vehicle that shares the sleek, fastback profile of the standard Xiaomi SU7 but with a big difference: it's been stretched. The additional length is behind the B pillar, a clear indication that the focus is on extra space for rear-seat passengers.

The current SU7, a large sedan in its own right, measures 196.7 inches in length with a wheelbase of 118 inches. Estimates based on the spy photos suggest this new variant could push its overall length to around 204.7 inches, and its wheelbase could grow by 3.15 inches to 5.9 inches. In the world of car design, it's a big jump that translates directly into more generous legroom for passengers in the back.

Adding extra length will completely shift the car's personality. The standard SU7 is marketed as a high-performance electric car for the driver. This long-wheelbase version seems to be chasing the executive transport market. Industry analysts compare the strategy to what Porsche does with its Panamera Executive models, focused on the comfort of those in the second row.

There are suggestions that the Xiaomi SU7 L could feature upgrades like wider, more luxurious rear seats, independent entertainment screens, and even amenities like a small refrigerator, transforming the back into a mobile office or lounge.

Of course, a longer and heavier car requires more than just new sheet metal. Xiaomi engineers will likely need to retune the suspension to maintain a balance between a comfortable ride and stable handling. The new electric car is expected to retain the SU7's advanced 800-volt architecture for fast charging and its sophisticated intelligent driving systems.

Xiaomi is staying silent about the new car, but the market is already buzzing about its price. If we were to believe industry insiders, the SU7 L could be priced above RMB 400,000 ($55,800). This would put it right in a gap between domestic rivals like the BYD Han, which costs around RMB 279,800 (about $39,000), and premium imports like the Tesla Model S, which starts at RMB 684,900 ($95,550) in China.

The appearance of this prototype confirms that Xiaomi's automotive ambitions extend far beyond two EV models. The company is reportedly testing several new electric cars at once, including a high-performance GT version of the YU7 SUV.

For now, the stretched sedan is still in its early testing phases, hidden under camouflage. Xiaomi, of course, has not confirmed its official name, final specifications, or a release date, but industry watchers are pointing toward a possible market debut early in 2026.
