Mashantucket — Foxwoods Resort Casino will unveil plans for its latest attraction Sunday but officials aren't saying what it is until then.

The site of the announcement — New Hampshire Motor Speedway — provides a clue, though.

Foxwoods representatives, joined by Richard Rawlings, star of the reality TV shows “Fast ’N Loud” and “Garage Rehab,” are scheduled to make “a special announcement” before Sunday’s racing begins, according to the Loudon, N.H., speedway. Rawlings will serve as the official pace car driver for the ISM Connect 300, part of the Monster Energy NASCAR Cup Series.

“Foxwoods has something big planned, too ...,” Rawlings is quoted as saying in a speedway publication.

While Foxwoods spokespeople declined Wednesday to discuss Sunday’s announcement in advance, Felix Rappaport, the Foxwoods president and chief executive officer, revealed months ago that the casino was planning to introduce an indoor go-kart track.

"... We thought it only fitting to have our friend Richard Rawlings, who knows a thing or two about cars and racing, be on hand to help us introduce the latest adrenaline-pumping experience coming to Foxwoods," Rappaport says in the publication.

Rawlings, an entrepreneur as well as a reality star, had been expected to open Richard Rawlings’ Garage Bar & Grill at Foxwoods in a partnership with a third party. After construction began, the project was stopped earlier this year.

Foxwoods is rolling out new attractions aimed at diversifying its nongaming amenities. It introduced two thrill rides — Sky Drop and Sky Launch — earlier this month and will soon unwrap a zip line linking The Fox Tower to the Mashantucket Pequot Museum and Research Center.
