Infiniti has been around for over 20 years, but
Nissan's luxury brand is still known primarily as the maker of the G35 and G37 coupes, aka the Skyline's soul sisters. Both are good cars, but Infiniti hasn't been able to surpass the
BMW 3 Series. Infiniti has been working hard in recent years to increase its sales and brand awareness by crafting a handful of sexy and luxurious eco vehicles. These concepts may not make it to market, but they are a great indicator of what the company has in store for the future.
