What Car? says...
It’s not uncommon for car and van manufacturers to work together to launch a new product. Pooling their resources lowers the development cost, and most customers will never know that their vehicle shares many of its components with at least one other model.
That’s the route that the Citroën ë-Relay has been down. It might be the latest large electric van to hit the market, but we’ve already seen its siblings, the Peugeot e-Boxer and Vauxhall Movano-e.
