Nissan will unveil the 370Z this autumn, but it won't be the only cool thing coming from the company. It seems that Infiniti is also working on a new baby coupe based on the Z.

But, while the future Z car will go on sale next year, the future baby Infiniti will only be seen in a concept version next year and production will follow in 2010.

The future baby coupe will be based on the same platform as the future Z. It is supposed under the hood there will be the 2.5-liter V6 engine, the smallest model in the Infiniti range.

The new baby Infiniti two-door will rival the BMW Z4 and Porsche Cayman for size and will be a rear-wheel drive two-seater hardtop.
