the rear doors. These may be fitted with step equipment to make boarding easier. Optional extras to van converted minibuses can include the addition of a rollsign for transit work, and/or a full-height walk-in door, for passenger access to the former cargo area. For public transport use, this door may be an automatic concertina type. For other uses, this may be a simple plug style coach door. Depending on the relevant legislation, conversions may also involve wheelchair lifts and tachograph equipment. A van conversion with a passenger area in the front and a storage area in the back, behind a fixed bulkhead, is called a splitter bus. Examples of vans used for these conversion minibuses are: Fiat Ducato Ford Transit Freight Rover Sherpa GAZelle Hyundai H350 Iveco Daily Mercedes-Benz Sprinter Renault Master Toyota Hiace Volkswagen Crafter Tata Winger Body builds Another method of building a minibus is for a second stage manufacturer to build a specific body for fitting to a semi-completed van or light truck chassis. These allow a higher seating capacity than a simple van conversion. Often, the second stage manufacturer is a bus manufacturer. In a body-on-chassis minibus, a cabin body is installed on a van or light truck chassis encompassing the drivers area. These designs may retain some outward signs of the original van, such as the hood and grill. Other designs are visually a complete bus design, and it is merely the chassis underneath that is from the van design. The body-on-chassis approach gives the advantage of higher seating capacity, or more room for passenger comfort, through a larger cabin area. There is also the advantage of being able to have the drivers seat positioned in a small cubicle, next to the main passenger entrance, allowing the driver to collect fares in a transit bus role. Examples of body built minibuses are: Busette (cut away chassis) Optare CityPacer (visually complete bus based on a van chassis) Plaxton Beaver (built on the Mercedes-Benz T2 and later the Vario chassis) Examples of vehicles used for this type of minibuses are: Ford Transit Freight Rover Iveco Daily Isuzu Elf locally built as the NQR bus Purpose built A next generation approach to the van-derived or cutaway chassis approach, is for manufacturers to produce an integral design, where the whole vehicle is purposely designed and built for use as a minibus. This is usually done by an integral bus
