1992 Carrera Cup USA edition


 
 

In 1992, Porsche introduced two Carrera lightweight cars sold by US dealers. Porsche sold 701 RS America in model years 1992-1994. The RS America was 76 pounds lighter than a standard Carrera 2, assuming it wasn't ordered with air conditioning, sunroof and radio. The Carrera Cup USA edition was 200 pounds lighter than a C2 and only 45 were made..

The 1992 Carrera Cup USA lightweight editions were imported by Porsche to compete in a national race series, but sponsorship fell through after  the cars were in the US, and Porsche, hurting for cash in 1992, sold them through their dealers. The car is basically the Euro Carrera RS with a few safety items to meet import rules. It is amazing, but the cars are street legal. My car is titled and licensed in CA. My car is VIN WPOAB2960NS420581. The serial numbers are not consecutive. It has a total of 578 miles. It is not altered or modified in any way. It is just like it came off the showroom floor. The Carrera Cup USA cars were written up in Pano May 1993 and Excellence Feb 1993. The offering price is $89,000. Earlier cars I looked at were in the high seventies and had been modified and had substantial mileage. Car located in Newport Beach, CA.

To appreciate how dramatically different and special this competition lightweight edition is, compare the many differences to a standard RS America, which was billed as a lightweight for competitive driving. See the below Lightweight Carrera Comparison between the RS America and the Carrera Cup USA edition.

As Porsche said in a private 1992 mailing to potential Carrera Cup USAbuyers, "this is a once in a lifetime opportunity".

Imagine, if you will, you had an opportunity to purchase 1973 Carrera RS lightweight with 578 miles. What would it be worth. A local collector won't take $150,000 for his 1973 Carrera RS that has been raced extensively, wrecked, repainted etc., etc.

I can offer no good reason for selling the car. I have 7 cars and a four car garage and would like to get everything under roof.
