widebody

Widebody is a term used in both aviation and automotive contexts to describe a vehicle designed or modified with a wider body than standard configurations. In aviation, widebody refers to commercial airliners whose cabin width allows two passenger aisles. These aircraft are typically used on long‑range or high‑capacity routes and contrast with narrow‑body aircraft, which have a single aisle. Common examples of widebody aircraft include the Boeing 767, 777, and 787 families, and the Airbus A330, A340, A350, and A380. Widebody aircraft generally feature larger fuselages and wings to support greater seating capacity and longer range.

In automotive usage, widebody describes modifications or factory designs that broaden a vehicle’s wheel arches and body panels to accommodate wider tires and a wider stance. Widebody kits typically replace or extend fenders and sometimes involve altered rocker panels to create space for the wider track. This can be aimed at improved handling, aesthetics, or performance in racing and show contexts. Factory widebody variants exist as well, offering increased width from the outset. Effects of widebody designs or modifications include changes to aerodynamics, weight, suspension geometry, and compliance with local regulations, with considerations for chassis rigidity and track width.

The term widebody therefore denotes increased width in two distinct automotive domains: aviation, where it denotes the two‑aisle cabin of many long‑haul airliners, and cars, where it denotes widened bodywork for broader tires and stance.
