If you are into rare classic cars, name Barthelemy de Lisle-Bouchard (Barthélemy de Lile-Bouchard) will surely pique your interest. This French manufacturer, active in the first half of the 20th century, is almost forgotten today - but its cars remain real gems for collectors. Unlike mass brands like Renault or Peugeot, de L'Isle-Bouchard produced exclusive hand-built cars that combined luxury with technical solutions that were innovative for their time.
Today, original copies are extremely rare - most of them were lost during the wars or dismantled for spare parts. However, those that survive are valued at hundreds of thousands of euros at auction. In this article we will analyze the history of the brand, its key models, technical features and give practical advice to those who are considering buying or restoring a car Barthelemy de Lisle-Bouchard.
Who is Barthelemy de Lisle-Bouchard: brand history
The company was founded in 1906 in Paris by engineer Barthelemy de Lisle-Bouchard, who previously worked at Panhard et Levassor - one of the pioneers of the automotive industry. De Lisle-Bouchard positioned his cars as an alternative to mass-produced models: they were assembled by hand, using high-quality materials and advanced technical solutions. For example, already in 1910 the brand experimented with 4-cylinder overhead camshaft engines - an innovation for that time.
The peak of popularity came in the 1920s, when de L'Isle-Bouchard produced luxury sedans and sports cars for the wealthy public. However, the Great Depression of the 1930s hit the company: demand for expensive cars fell, and competition from Bugatti and Delage became unbearable. In 1934, production was stopped, and the last car rolled off the assembly line in 1936. In just 30 years, about 1,200 cars — by the standards of the auto industry, this is a drop in the ocean.
- 📅 1906 - founding of a company in Paris.
- 🏆 1912–1925 - participation in races Grand Prix (including victory in the under 3 liter class in 1923).
- 💥 1934 - bankruptcy and closure of production.
- 🔍 Today — less than 50 original copies have survived.
Interesting fact: de Lisle-Bouchard was one of the first to use aluminum body parts for weight loss. This decision was later adopted by Alfa Romeo and Jaguar.
Key models Barthelemy de Lisle-Bouchard
Over its history, the brand has released about two dozen models, but only a few of them have become legendary. Below are the most significant cars that are of greatest value to collectors today.
| Model | Years of production | Engine | Features | Approximate cost (2026) |
|---|---|---|---|---|
| Type A | 1907–1910 | 2.4L I4, 20 hp | First production model, chain drive | €80 000–€120 000 |
| Type D Grand Sport | 1912–1914 | 3.0L I4, 45 hp | Racing version, winner Coupe de l'Auto 1913 | €250 000–€400 000 |
| Type M | 1922–1928 | 1.5L I4, 30 hp | Compact city car with electric start | €60 000–€90 000 |
| Type R Cabriolet | 1929–1932 | 2.0L I6, 50 hp | Luxury convertible with a body from Labourdette | €300 000–€500 000 |
Deserves special attention Type D Grand Sport - one of the most successful racing cars of the early 20th century. Its engine is two overhead camshafts accelerated the car to 130 km/h, which was a fantastic figure for 1913. Today, original copies of this model are practically never found on the market - the last sale at auction Bonhams in 2019 amounted to €420,000 for a partially restored example.
Technical features: what makes these cars unique
De L'Isle-Bouchard's cars stood out not only for their design, but also for their engineering solutions. Here are the key technical features that were ahead of their time:
- ⚙️ Engines with overhead camshafts (OHC) - appeared in 1912, when most competitors were still using lower valve engines.
- ⚡ Electric starter - serially installed since 1922 (at Ford it appeared only in 1919).
- 🔧 Independent front suspension - experimental samples were tested in 1928 (5 years before Citroën Traction Avant).
- 🛡️ Aluminum body panels - used to reduce weight in racing versions.
However, there were also weaknesses. For example, early model gearboxes suffered from insufficient reliability of synchronizers, and the cooling system required frequent maintenance. In addition, due to manual assembly, many parts were non-fungible even within the same model - this greatly complicates restoration today.
Why did de L'Isle-Bouchard lose to Bugatti?
The main reason is insufficient funding. Unlike Ettore Bugatti, de L'Isle-Bouchard did not have wealthy investors. In addition, the brand relied on exclusivity rather than serial production: for example, bodies for Type R made to order from Labourdette or Vanden Plas, which increased the cost by 2–3 times compared to competitors.>

Restoration: difficulties and cost
Restoring de L'Isle-Bouchard's car is not just a repair, but art. Main challenges:
- 🔨 Lack of spare parts. Most parts will have to be made to order. For example, pistons for Type D Today only two workshops in France make it.
- 🎨 Body work. Original bodies are often made of thin steel or aluminum - their restoration requires specialists coachbuilding (manual body assembly).
- 🔧 Engine. Engines with overhead camshafts require precise valve adjustment - an error can lead to irreversible damage to the block head.
Approximate costs for a complete restoration:
- 🔧 Engine: €20,000–€50,000.
- 🚗 Body: €30,000–€100,000 (depending on condition).
- 🎨 Painting and finishing: €15,000–€40,000 (original colors restored from archival photographs).
- 📜 Documentation and certification: €5,000–€10,000 (to obtain FIVA Passport - international certificate of authenticity).
The most expensive part of the restoration is finding the original parts. For example, a radiator for Type R in good condition it can cost up to €12,000, and its replica can cost up to €8,000 (production time is 6-12 months).
The average time for a complete restoration is 2–4 years. It is important to find a workshop that already has experience working on French cars from the 1920s and 30s. For example, Atelier Retro Passion in Lyon specializes in rare stamps, including de L'Isle-Bouchard.
Legal nuances: registration and operation
If you plan to not only exhibit the car at shows, but also drive it, you will have to deal with the legal aspects. In Russia and Europe the rules are different:
In Europe (especially France):
- 📋 The car must have Carnet de Passage en Douane (if imported from abroad) or French Carte Grise Collection.
- 🚦 To participate in rallies or exhibitions you need FIVA Identity Card (confirms authenticity).
- 💰 Luxury tax is not charged if the car is over 30 years old and is used no more than 1 time per week.
In Russia:
- 📄 To register with the traffic police you will need
PTS marked "collectible"(to be completed through an examination at NIIAT). - 🚗 Technical inspection is carried out according to a simplified scheme (without checking the environmental class).
- ⚠️ Attention: if a car is imported from abroad, the customs duty can reach 30% of the cost (even for rarities).
Important point: in most countries, for classic cars there are operating restrictions. For example, in France it is prohibited to drive on motorways in cars older than 1960, and in Germany a special sign is required "Oldtimer" (registration cost is about €200).
Before purchasing, check whether the car can be registered in your country. For example, in Switzerland, cars before 1930 require a special permit from the cantonal department of transport.
