At the heart of French automotive innovation in 2025, FacteurDix stands out with a bold and radical approach. Born in the wake of the prestigious Lépine competition, this Norman start-up aims to revolutionize electric mobility with its Line car, an ultra-light two-seater tricycle prototype. Led by two engineers who swapped the Exxon-Mobil oil industry for the challenges of electricity, this initiative seeks to reduce energy consumption by a factor of ten. A daring bet in a sector dominated by heavyweights like Renault, Peugeot, Citroën, Volkswagen, Tesla, BMW, Nissan, Fiat and Ford. The vehicle promises to seduce with its energy efficiency, its minimalist design and its top speed capable of reaching 165 km/h. However, its extreme features and high price raise questions about its accessibility and everyday usefulness. However, this project is part of a broader movement of innovation where disruption and technical audacity are often the driving forces behind major technological advances.
An innovative and disruptive design in the French automotive landscape
FacteurDix stands out as an innovative response to current energy challenges. Its Line car adopts a unique concept. Unlike the majority of classic electric vehicles offered by Renault, Peugeot or Citroën, it relies on extreme sobriety and lightness to drastically reduce electricity consumption. The design stems from a clear objective: to minimize aerodynamic drag and weight. The ovoid bodywork is reminiscent of pioneering models such as those of Panhard, CD or René Bonnet, referring to a refined style typical of passionate engineers’ cars.
The original tubular structure, still in the prototype phase, will give way to a composite monocoque chassis by 2029-2030. This technical choice aims to keep the weight limited to around 500 kg. This lightness is a key factor in achieving a targeted fuel consumption of just 4 kWh/100 km, a remarkable performance compared to the current standard of 15 kWh/100 km for conventional electric models. In terms of form, this electric tricycle stands out for its four-wheel configuration, including two closely spaced and twin rear wheels, optimizing cornering stability.
The car features two 25 kW motors positioned in the front wheels. This engine develops a combined power of 68 horsepower, a feat that allows the vehicle to comfortably reach a top speed of 165 km/h, compatible with highway traffic. In short, FacteurDix is promoting a lightweight yet high-performance vehicle—a difficult balance to achieve. This promise is reminiscent of the technical innovations seen at Tesla, BMW, and Volkswagen in the race for energy efficiency. Key features include:
- 🚗 Ultra-lightweight: approximately 500 kg to limit fuel consumption 🔋
- Targeted fuel consumption: 4 kWh/100 km, an ambitious energy efficiency target ⚡ Dual motors in the front wheels, total 50 kW (68 hp)
- 🛣️ Top speed: 165 km/h for highway use ⌛
- Fast charging: from 20 to 80% in 10 minutes This approach shows that even in the face of legacy manufacturers like Nissan or Fiat, a French startup can leverage innovation to position itself in a niche that promises technological breakthroughs. Discover an innovative automobile that redefines the standards of modern driving. Combining performance, advanced technology, and elegant design, this car revolutionizes your experience on the road.

| https://www.youtube.com/watch?v=S4irWmdufa0 | A vehicle designed for the energy challenges and regulations of the future | With the objective of addressing a crucial problem: drastically reducing energy consumption, FacteurDix is setting a new standard. The Line car, although classified in the L5e category of motorized tricycles, features a hybrid configuration between a conventional car and a tricycle. This technical choice stems not only from a desire for lightweight design but also from a strategy to make the vehicle accessible with an A license—an important feature in terms of legislation and ease of use. |
| This approach is intentional, but it doesn’t correspond to the usual specifications for an average consumer accustomed to spacious and versatile models from Renault, Peugeot, or Ford. Here, the cabin is ultra-narrow, with the two seats arranged in a staggered manner to optimize the exterior dimensions. Despite this spartan appearance, the engineers are ensuring future improvements in comfort and finish, with robust features such as: | 🔧 | Composite monocoque chassis |

- 🛡️ Safety equipment: ABS, ESP integrated as standard 🔊
- Integrated car radio for everyday use ⚙️
- Ergonomics and assistance options under development This level of equipment, similar to that offered by leading brands like Citroën and Volkswagen, should reassure future buyers despite the model’s minimalist appearance.
- It should be noted that the small trunk capacity, around 90 liters, limits utility uses. This constraint, although related to the weight/range tradeoff, raises the question of real needs in an era where traveling in an economical car is becoming more important than ever. The future of this type of low-impact autonomous vehicle therefore also depends on adapting habits and mindsets, particularly in a context where fast charging is developing, a key point that the market in general—from Tesla to Nissan—has not yet fully aligned.
