A Porsche 911 GT3 was recorded at 194 mph (312 km/h) on the A40 in Haute‑Savoie — roughly 113 mph (182 km/h) over the 81 mph (130 km/h) limit, and the fastest highway speed French police say they have recorded. After the standard 5% radar tolerance the enforcement speed was about 186 mph (300 km/h). The foreign‑registered driver, reported as a 48‑year‑old Swiss national, had their licence seized and the car impounded; they paid a €1,500 deposit and face fines, a driving ban and possible prison time.

Speeding is dangerous. Late at night on the A40 motorway in Haute‑Savoie, southeastern France, a Porsche 911 GT3 was recorded traveling at an extraordinary 194 mph (312 km/h) — the highest speed French police say they have measured on a highway.
French autoroutes carry a legal limit of 81 mph (130 km/h). The Porsche’s measured speed exceeded that limit by roughly 113 mph (182 km/h). After the standard 5% radar tolerance applied in France, the enforcement speed was about 186 mph (300 km/h) — still roughly 105 mph over the limit.
The Gendarmerie de la Haute‑Savoie noted that at 312 km/h a car covers nearly 87 metres per second, underlining the extreme danger when other road users remain present — even at night.
Authorities stopped the foreign‑registered Porsche and, according to Europe1, the driver was a 48‑year‑old Swiss national. Police confiscated the driver’s licence, impounded the Porsche and required a €1,500 security deposit. The unnamed driver now faces sanctions that could include a fine of up to €3,700, a ban on driving in France and up to three months in prison.
Context and Reaction
France’s previous recorded motorway high was 178 mph (287 km/h), recorded on the same stretch of the A40 in May 2026 by an Audi RS3.
The incident provoked vigorous online debate. Some users argued for income‑based fines similar to systems used in Switzerland, while others emphasised the simple physics of reaction distance and the many hazards — animals, debris, broken‑down vehicles or pedestrians — that make extreme speed particularly reckless even on lightly trafficked roads.
Comment: "At 312 km/h, we travel nearly 87 metres per second. In other words, by the time you spot an obstacle and react, you may already have passed it."
Officials reiterated that such behaviour is both illegal and dangerous, thanking law enforcement for intervening and reminding drivers that limits exist to protect everyone on the road.
Note: The driver’s identity has not been disclosed publicly. Investigations and any subsequent legal proceedings will determine the final penalties.
