Xiaomi Tests Longer SU7 Sedan, Hinting at Executive-Class Rear-Seat Luxury

Xiaomi's SU7 Sedan Gets a Stretch for Enhanced Passenger Comfort

Following the triumphant debut of its initial electric vehicle offerings – the sleek SU7 sedan and the versatile YU7 crossover – Xiaomi is already signaling its next strategic move. Spy shots emerging from China reveal camouflaged prototypes of an extended SU7 variant. While the unmistakable, elegant silhouette of the standard SU7 is preserved, a key alteration is immediately apparent: a notable increase in its overall length. This added dimension is strategically placed behind the B-pillars, a clear indication that the company is prioritizing an elevated experience for rear-seat occupants.

From Driver's Car to Mobile Lounge: The SU7 L's Transformation

Even in its current iteration, the standard Xiaomi SU7 is no shrinking violet, already classifying as a large sedan with a respectable 4997 mm length and a 3000 mm wheelbase. Initial visual assessments of the new prototype suggest a significant growth spurt, potentially reaching up to 5200 mm in length, with the wheelbase likely to expand by an additional 80-150 mm. In the automotive world, such an increase is far from trivial; it translates directly into a more generous legroom for those seated in the rear. This expansion fundamentally shifts the character of the vehicle. Whereas the regular SU7 is positioned as a high-performance electric car for the enthusiastic driver, this stretched modification seems squarely aimed at the executive sedan segment, where supreme rear-seat comfort reigns supreme. Industry analysts are already drawing parallels to offerings like the Porsche Panamera Executive, a model specifically crafted for clients who frequently travel with a chauffeur.

A Glimpse into Executive Luxury: Potential Features

While official nomenclature remains elusive, industry chatter points to the potential designation of 'SU7 L' for this elongated model. Expectations are high for it to feature wider, more supportive rear seats, individual entertainment screens for passengers, and perhaps even creature comforts like a compact refrigerator. These enhancements could effectively transform the rear cabin into a productive mobile office or a truly luxurious lounge space, redefining in-car travel for business or leisure.

Engineering the Comfort: Balancing Dynamics and Ride Quality

The extended body and increased mass necessitate more than just aesthetic adjustments. Xiaomi's engineering teams will undoubtedly need to recalibrate the suspension system to maintain a harmonious balance between outright comfort and agile handling. However, it's anticipated that the new variant will retain the advanced 800-volt architecture, a key feature of the SU7 that enables remarkably swift charging, alongside the sophisticated suite of driver-assistance systems already well-established in the current model.

Xiaomi's Expanding EV Ambitions

The emergence of this extended sedan prototype is a resounding affirmation that Xiaomi's automotive aspirations extend well beyond its initial two models. Whispers from inside the industry suggest that the company is concurrently testing a portfolio of new electric vehicles, including a more potent 'GT' version of the YU7 crossover, promising enhanced dynamic capabilities. At present, the elongated SU7 remains in the nascent stages of development, cloaked in camouflage, and devoid of official specifications or release timelines. Nonetheless, astute market watchers speculate that a public unveiling could grace the market as early as the first half of 2026.

Pricing and Competitive Landscape

While concrete pricing details are yet to be disclosed, market intelligence suggests a starting point exceeding 400,000 yuan (approximately €47,600). This positioning would place the potential SU7 L in an intriguing intermediate space, sitting above domestic rivals such as the BYD Han (starting around €33,300) and below imported premium benchmarks like the Tesla Model S (which starts at roughly €81,600 in China). This strategic pricing could carve out a compelling niche for Xiaomi in the increasingly competitive luxury EV sector.
