7. Renault Avantime
The Renault Avantime, produced from 2001 to 2003, was a distinctive coupe-minivan hybrid that defied conventional automotive design. Its most notable feature was the double-hinged doors, each measuring 140 cm and weighing over 50 kg, which required a unique opening mechanism to accommodate their size and weight. This design choice, while innovative, led to practical challenges, such as limited rear seat access and potential difficulties in tight parking spaces. The Avantime’s avant-garde styling and unconventional features positioned it ahead of its time, appealing to a niche market seeking something different. However, its high price point and limited practicality resulted in poor sales, with only 8,557 units produced before its discontinuation in 2003. Despite its commercial failure, the Avantime remains a cult classic, admired for its bold design and the risk Renault took in its creation. (Autocar)
