Infiniti Q80 Inspiration grabs for a luxury spotlight ahead of Paris

It's not just Cadillac that wants to establish itself as a top-line luxury car brand. Nissan's Infiniti division has been on the same march for the past several years — rolling out new models, taking over the branding of the Renault-based Formula 1 car, making Sebastian Vettel a "brand ambassador" — with about as much success. Infiniti will outsell Cadillac this year worldwide, but still lags the Germans and even Lexus in country-club prestige.
