Was out tooling around on my mountain bike round Perth yesterday, and saw one of the local public transport system buses with a HUGE diamond badge on the front! Cool.
A bus company "King Bros" have several of the Renault busses in their fleet. They operate up and down the Pacific Hwy near our place. Also now that Renault owns a big chunk of Mack Trucks I quite often see the big diamond on the front of some semi's. The prime mover is the same shape as a Mack except for the diamond cheers! .
To be honest, buses are usually made by a coachbuilder who then fits a motor company's running gear and equipment. Those same bus bodies you see in the above link I know also run Mercedes Benz, MAN and other brands of engines as well.
Renault do make their own busses.. but that one in the picture certainly isnt one of them.
<a href="http://www.transbus.org/construc/renault.html" target="_blank">Renault Bus</a> is a link that shows some. As it says, Berliet and Saviem were combined to be Renault V.I (Véhicules Industriels) in 1978. In combination with IVECO and a further formed company, IRISBUS they then make good looking, Renault designed (as you can see familiar similarity with even the Master, Trafic and the Renault V.I. fleet (www.renaultvi.com).
