I said "most" do not return. Anyway, the three you mention not sure qualify as Dongfeng comes back due to its Volvo relation (it is partly owned by Volvo), Mapfre for financial returns due to the Spanish tax benefits (Alicante is obliged to deliver a team in its contract. The tax benefits are in place to help them fulfil this obligation). Vestas seems genuine as it has unfinished business although I suspect they are going to have a very small involvement this time around (i.e. limited activation from their side). But don't get me wrong, any reason is valid to join the race, being strengthening the business relationship with Volvo, financial gains, or unfinished business. The issue are the Puma's, Abu Dhabi, Groupama, Ericsson, Movistar/Telefonica, ABN Amro, SCA, etc. that came and went.
