"A quad coup\u00E9 is a car body style featuring bi-parting side doors \u2013 located either on one or both sides of the vehicle.The bi-parting doors typically feature a longer front door and a short rear door, without a pillar in between. The configuration offers both a more 'sporty' aesthetic than compared to a traditional sedan, and the utility of 4-doors, though the doors operate inter-subdependently."@en .
