I hope the brand does well. Yes a diesel is important, but if I had enough dough for the tasty looking coupe, or the 4x4 for that matter, I'm pretty sure I would be going for the petrol versions. Apart from anything else, I think Infiniti sounds better than Lexus. Lexus sounds like the kind of name Ikea would give to a cheap leather sofa. Or the name of an exotic table dancer. Also, from a snobby point of view - which is surely a big issue when looking at 'premium' badges such as these - as far as I am aware, none of the Infiniti models are rebadged Nissan's in the way that some of the Lexus models have been, like the IS and whatever the Toyota Soarer was called when it was sold as a Lexus.
