We are all very excited to see the Renault->ke72 Alpine->ke2338, but it looks like we may have to wait longer than expected. According to Autocar, there was a secret customer clinic where the automaker showed off its upcoming sports car. Well, apparently customers didn't respond the way the Renault team had expected, so it sent the car back to the drawing board for a redesign. This latest delay will push the sports car->ke506's release back by about a year -- somewhere in late 2016.

Reportedly, there are also some frustrations from the Caterham->ke1252 side, as its bosses had signed off on the design some time ago and has been on hold since. Caterham needs to get to polishing off the under-skin components, so we can understand that frustration.

Caterham's was diplomatic and did not comment specifically on the frustrations. He did however, admit that there are some issues that are causing frustrations for both teams, but Renault assured him that this project is a top priority.

The Renault Alpine project is actually a joint venture that will also net Caterham with an all-new sports car with similar styling. Renault recently launched a concept version of the car that I found rather attractive, but I have yet to see what the model that Renault showed off at its customer clinic looked like.

Driving the Alpine Concept's was a 3.5-liter V-6 that produced up to 400 horsepower, but experts anticipate the production model to be closer to 250 horsepower -- the Caterham model will have nearly 300 ponies.
