Pretty much the only thing that decides if it is car derived is the GVW. Under 2 tonnes laden GVW = Car Derived Van.
Therefore Berlingo, Kangoo, Astra = Car Derived.
Most Doblos, Dispatch, Caddy, Connect = Light Commercial = lower speed limits. This is especially crazy as some of the Doblos have a GVW of 2010 kg (10 kg over the limit!)
Now go and look at what an UNLADEN Range Rover weighs yet still classed as a car…….
We have a new Dispatch Combi (ace van by the way – 6 proper seats, and room for 6 bikes with just front wheels out, wipe clean rubber floors and huge tailgate to shelter under). Because it is a factory built Combi, it has been homologated as a car – therefore my V5 says body type = MPV and taxation class = diesel car (so regular car speed limits apply).
For Connect etc, bare window vans still class as Light Commercial. But windows (small ones in sides and rear door) plus rear 2+ seats = dual purpose vehicle and back to regular speed limits again. New vans of this type should (but don’t always) come correctly described on the V5 (because it is the V5 info that the police convict off). A van converted with seats etc after registration needs an SVA inspection to get V5 updated.
If you want to be legal at regular speeds in a Connect, then need to get a Crew Van with glass in all the doors (make sure it is correctly registered). We were pretty impressed with the Connects we tried but was 14 weeks delivery from Turkey. Ford also do an aftermarket steel tube / mesh bulkhead for behind the rear seats – unlocks and slides forward if you fold the rear seat (handy to keep bikes and people separate) Not as well finished as the Dispatch.
Is that enough detail? 😉
