Umm, it is a Vodafone McLaren. It's a Vodafone McLaren-Mercedes to be precise. So calling the Renault a Lotus Renault is appropriate when referring to the full name of the team. Lotus are sponsoring Renault and the sponsor name comes first. It used to be ING Renault for example. So even though there will be a car called a Renault and a car called a Lotus-Renault there will team called Lotus Renault and another team called (insert sponsor here) Lotus-Renault. Clear as mud really.
