The return of the Chrysler Viper to the Le Mans 24 Hours was confirmed in Paris on Friday when race organisers unveiled the entry list for this year's race.
Two GTE Pro class Viper GTS-Rs have been entered under by the Riley Technologies-run SRT Motorsports team, which is masterminding the US muscle car's return to racing.
The cars will be badged as SRTs after after Chrysler's Street & Racing Tuning brand.
Marc Goossens and Dominik Farnbacher, who were both part of SRT's partial campaign in the American Le Mans Series in 2012, have been slated as the drivers of the car.
SRT director Beth Paretta, whose remit covers motorsport, said: "Our goal in our first year was to be invited. We are so excited to be returning to Le Mans; we couldn't be more excited about being back on the world stage."
The two Vipers bolster an impressive GTE Pro class that includes two factory AstonMartin Vantage GTEs and two 991-shaped Porsche 911 GT3-RSRs, to be fielded by a Manthey-run works team.
ACO sporting director Vincent Beaumesnil said: "I don't think I have seen so many great GT cars on the grid. We have five manufacturers with two cars each, who are all are going to be battling it out at Le Mans."
There are only eight LMP1 prototypes on the entry for Le Mans, including three Audis and two Toyotas.
This follows the late withdrawal of the British JRM squad, which has opted to withdraw for financial reasons, and OAK Racing's decision to focus its P1 programme on the development of its all-new 2014 car.
