Aixam 500.4
The Aixam 500.4, launched in 1999, represents an important milestone in the evolution of light quadricycles from the French manufacturer Aixam. Founded in 1983 in Aix-les-Bains, Savoie, Aixam specialized in producing license-free vehicles, a niche segment particularly developed in France and several European countries. The 500.4 follows this specialization, offering an accessible mobility solution for people without a traditional driver's license or those whose licenses have been suspended. The "4" in its designation clearly indicates its seating capacity: four seats, a relatively rare configuration in the light quadricycle universe of the era, where two-seat models largely dominated the market. The design of the Aixam 500.4 reflects the technical and regulatory constraints specific to light quadricycles. With its compact dimensions and fiberglass-reinforced polyester body, the vehicle displays a stocky and functional silhouette. European legislation limiting maximum speed to 45 km/h and power to 4 kW (approximately 5.4 horsepower) for this vehicle category meant Aixam had to design an optimized cabin to offer acceptable comfort despite these restrictions. The interior, although modest, provides four seats arranged in a 2+2 configuration, with rear seats better suited for children or short trips for adults. Technically, the 500.4 was equipped with a Kubota twin-cylinder diesel engine of 400 or 500 cc depending on versions, hence its designation. This diesel choice was driven by the pursuit of reduced consumption and proven reliability, with Kubota engines recognized for their robustness in the industrial sector. The continuously variable automatic transmission (CVT) or belt-drive transmission greatly simplified driving, a major asset for a clientele sometimes unfamiliar with traditional automotive driving. The tubular steel chassis provided sufficient structural rigidity while maintaining limited weight, essential to respect the 350 kg maximum authorized for a light quadricycle (excluding batteries for later electric versions). The positioning of the Aixam 500.4 primarily targeted the French and European license-free vehicle market. Its four-seat configuration distinguished it from competitors and allowed it to meet family or professional needs requiring the transport of several passengers over short urban or suburban distances. During its production period, which extended until approximately 2007, the model underwent several minor evolutions concerning standard equipment, interior finishes, and some aesthetic adjustments. Aixam progressively improved the equipment level offered, including in certain versions electric windows, power steering, and more efficient heating. The reception of the 500.4 in the market was generally positive within its target clientele. Users appreciated its ability to transport four people, its economical consumption, and its ease of parking in urban environments. However, limitations inherent to light quadricycles, notably the restricted maximum speed and modest performance, limited its use to urban and suburban environments. The legacy of the 500.4 is found in subsequent Aixam models that continued to offer four-seat configurations, thus contributing to democratizing accessible mobility in the license-free vehicle segment.

Technology
Technologies, engines and platforms
The Aixam 500.4 relied on a Kubota twin-cylinder diesel engine of 400 to 500 cc, developing approximately 4 kW to comply with light quadricycle regulations. The continuously variable automatic transmission or belt-drive system facilitated driving without clutch or manual gear shifting. The tubular steel chassis offered rigidity and lightness, while the fiberglass-reinforced polyester composite body limited total weight. The steering, initially mechanical, evolved toward power assistance on certain versions. Independent front suspensions and a rigid rear axle provided basic comfort. The braking system combined disc brakes at the front and drum brakes at the rear, adapted to the limited speed of 45 km/h.
Tires and wheels
Tire and wheel compatibility
Tire and wheel dimensions on the Aixam 500.4 may vary depending on the year and specific version. It is recommended to consult the door jamb label or owner's manual for the exact specifications of your vehicle.
