After a week of testing at the Sebring International Raceway, the Nissan DeltaWing headed to Atlanta for final preparation prior to its scheduled European test programme.

The programme kicked into high gear on March 13 with the launch of the Nissan partnership in London followed by the official unveiling of the race car at Sebring two days later on March 15.

With the initial prototype built by Dan Gurney's All American Racers group in California, Panoz's EMT organisation were put to work this week to fine tune components and bodywork - using the lessons learned from the initial shakedown test at Buttonwillow in California and the Sebring test to refine the Nissan DeltaWing "mobile experiment".

The Nissan DeltaWing will debut at this year's 24 Hours of Le Mans as an additional 56th entry - an opportunity reserved by the event organisers the Automobile Club de l'Ouest for vehicles featuring new and innovative technologies.

The DeltaWing programme was originally launched at last year's 24 Hours of Le Mans by Panoz, Gurney, DeltaWing designer Ben Bowlby and Highcroft Racing's Duncan Dayton.

Michelin also has embedded personnel in the programme with the car running unique development tyres previously unseen in international sportscar competition. The front tyres on the Nissan DeltaWing are only four inches wide.
