"Xiaomi SU7 Ultra: How a Tech Company Built a 1548hp EV That Outperforms Porsche on Track"

**Xiaomi** is a consumer electronics company. Its primary products are smartphones, smart home devices, and wearables. In February 2024, it launched the SU7 — a mid-size electric sedan positioned to compete with the Tesla Model 3. Then, in early 2025, it launched the SU7 Ultra — a 1548-horsepower variant built around a Nürburgring lap time and a specific competitor: the Porsche Taycan Turbo GT.

The SU7 Ultra lapped the Nürburgring Nordschleife in 6 minutes 46 seconds. The Porsche Taycan Turbo GT's factory lap is 7 minutes 7 seconds. The gap is 21 seconds, which is substantial in Nürburgring terms.

Let's look at what produces that gap, what it costs, and what it means.

## The Numbers

| Spec | Xiaomi SU7 Ultra | Porsche Taycan Turbo GT | Tesla Model S Plaid |
|------|-----------------|------------------------|---------------------|
| System power | 1,548 hp (1,154 kW) | 1,108 hp (826 kW) | 1,020 hp (761 kW) |
| Torque | 1,770 Nm | 1,340 Nm | 1,420 Nm |
| 0–100 km/h | 1.98 sec | 2.2 sec | 2.1 sec |
| Top speed | 350 km/h | 305 km/h | 322 km/h |
| Nürburgring lap | 6:46.874 | 7:07.55 | N/A (unofficial) |
| Battery | 93.7 kWh | 105 kWh | 100 kWh |
| Weight | 2,205 kg | 2,345 kg | 2,162 kg |
| Price (China) | ¥814,900 (~$113,000) | ~$250,000 | ~$110,000 |

The power figures require context. **1,548 hp** is produced by three electric motors — two on the rear axle, one on the front — through a motor architecture derived from Xiaomi's SU7 motorsport prototype program. At the rear, a carbon fibre active rear wing provides up to 285 kg of downforce at maximum deployment. The chassis uses an adjustable air suspension system that lowers the vehicle at speed and stiffens damping for track mode.

The weight of 2,205 kg is heavy for a sports car. The fact that a 2.2-tonne vehicle can lap the Nordschleife in 6:46 reflects what extreme power output, sophisticated torque vectoring, and aerodynamic engineering can achieve regardless of mass.

## How Xiaomi Built a Track Car in Four Years

Xiaomi announced its automotive ambitions in March 2021. The SU7 Ultra went on sale in March 2025. That is four years from first public announcement to a production car that holds a Nürburgring record. The typical automotive development cycle for a new model is five to seven years, and that's for established manufacturers.

**Xiaomi** achieved this timeline through three mechanisms. First, it licensed chassis and powertrain knowledge rather than developing everything from scratch — the SU7's platform borrows from existing EV architecture approaches used by its partner suppliers in China's EV ecosystem. Second, it applied consumer electronics development methodology to automotive: rapid iteration, software-defined features, and vertical integration of the digital systems. Third, it hired talent aggressively from established automotive companies — Xiaomi's automotive division recruited engineers from BMW, Bosch, and Continental.

The Nürburgring campaign served both a development and a marketing function. Testing at the Nordschleife generates data about the car's limits under sustained high-speed and high-lateral-load conditions that ordinary road testing cannot replicate. It also generates a headline number that is directly comparable to established benchmarks.

## What It Means for the Chinese EV Sector

The SU7 Ultra is not a mass-market product — at ¥814,900, it reaches a narrow slice of buyers. Its significance is demonstrational. **Xiaomi** is establishing that Chinese automotive technology is capable of exceeding established European premium benchmarks on the metrics that the premium automotive market uses to define itself — lap times, acceleration figures, top speed.

This is not primarily about the SU7 Ultra selling in volume. It is about what the SU7 Ultra signals for Xiaomi's broader lineup and for Chinese EV positioning internationally. A company that can build a 6:46 Nürburgring car has demonstrated engineering credibility that transfers to perception of its more accessible products.

BYD has pursued a similar strategy with its Yangwang U9 hypercar. Li Auto has demonstrated sophisticated extended-range technology. The pattern across Chinese EV manufacturers is a deliberate effort to establish technical credibility at the performance extremes before expanding into premium global markets.

## The Verdict

**Xiaomi** built a 1548-horsepower EV that holds the Nürburgring production car record, costs half the price of the Porsche Taycan Turbo GT it explicitly targets, and comes from a company that sold smartphones five years ago. All of those facts are accurate.

Whether the SU7 Ultra is the better car in a real-world sense depends on what you value. The Taycan Turbo GT offers superior interior quality, an established dealer network, and 100 years of Porsche engineering culture behind its reliability engineering. The SU7 Ultra offers more power, a faster lap time, and a lower price.

The point is not which car you would buy. The point is that the competition is real. A Chinese technology company has built a car that forces the established European performance EV market to respond on technical grounds rather than dismissing the challenge. That shift — from a question of *whether* Chinese EVs can compete at the performance tier to *how* European manufacturers respond — is what the SU7 Ultra actually represents.
