ATTACHMT: ATTACHED TO LETTER DATED 10/15/87 FROM ERIKA Z JONES TO GT DOE; VSA 108, STANDARDS 208, 216 LETTER DATED 09/18/87 FROM ERIKA Z JONES TO J. DOUGLAS HAND

TEXT: Dear Madam

Lotus is proposing to introduce a convertible car into the United States. It is planned to develop and certify the car as a two seat convertible. It is recognised, however, that if no other provision is made, accessory manufacturers may offer 'hardtop' conversions to our customers. In anticipation of the latter possibility, a factory manufactured and approved quality hardtop optional conversion would be offered. The hardtop would consist of a composite roof structure, which would replace the convert ible canopy and support frame. The removal of the latter would reveal a trimmed luggage shelf behind the two designated seating positions. It is conceivable that, although the shelf would not be recognised as a seating area, small occupants could trave l in this area. The fitting of the hardtop would in no way degrade the quality, reliability, or safety of the vehicle. The application of the hardtop conversion is depicted in the accompanying illustration.

It is possible that, whilst vehicles would be imported as convertibles, individual dealers might elect to fit hardtops to new vehicles and display them in their showrooms in this condition.

Could you please give interpretations with respect to the following:-

1. Convertibles are not required to conform to the roof crush requirements of FMVSS 216. Would the designation of the vehicle as a convertible remain unaffected by the hardtop conversion?

2. Would the requirement for seating and restraint system provision remain unaffected by the hardtop conversion?

Please do not hesitate to contact the undersigned for any further information, or discussion regarding the above.
