I've just spent a week driving the Infiniti Q50 Hybrid, trying to put the car into context with answers and comments from interviews with executives at the Frankfurt and Geneva motor shows.

Having spent time with Andy Palmer and Johan de Nysschen, respectively Nissan’s British head of product planning and Infiniti’s global boss, it is clear that Nissan is ambitious to turn Infiniti into a global force in the premium market, where investments return bigger profits and the market keeps on growing, despite the global downturn.

In fact, Palmer reckons 50 per cent of the profits in the global car industry come from premium models, with three brands generating 80-90 per cent of that profit.
