In 1994, to promote the new Mark 5 Transit, Supervan 2 was rebuilt as Supervan 3. This was the first time that Supervan had been used to promote a new model, rather than a model already nearing its end of life. A seven-eighths scale reduced replica of the new bodyshell was fitted, together with a new engine, a Cosworth HB. The work was carried out by DRL Engineering of Suffolk. This version also had the longest promotional lifespan, appearing in public until 2001. With several liveries in Ford's blue and white over the years, its final appearance was in Royal Mail red, celebrating Ford's new contract to supply their vans, taking over from a long arrangement with Leyland DAF Vans.

In 2004 a refurbishment was announced. The engine was replaced with a more practical Ford-Cosworth Pro Sports 3000 V6 engine, and the 1984 Ford Motorsport blue and white livery was restored. This work was carried out by Sporting and Historic Car Engineers of Bicester.

In 2014 it was rebuilt again this time using ground effects wing under the van and a V10 F1 engine.
