The most successful private team in North American sportscar racing has announced that it will field four Aston Martin Vantage GT4s in the 2014 Pirelli World Challenge.

TRG-AMR North America also confirmed Nick Esayian, Jorge De La Torre and Drew Regitz as three of its drivers in the series' GTS class, while the fourth Vantage GT4 will be a "house" car open to selected drivers at each event.

The 2014 Pirelli World Challenge is one of the most prestigious and competitive racing series for production-based sports cars in North America, and its GTS season consists of 16 rounds at nine venues across North America, starting 28-30 March on the streets at St. Petersburg in support of the IndyCar Series.

"The ultra-competitive Pirelli World Challenge is an ideal series to continue to expand the excitement and prestige of the Aston Martin brand in North America," TRG-AMR CEO Kevin Buckler noted, "The GT4 Vantages are amazing machines and really seem to excite the fans. There is always a crowd around our cars, which is really cool.

"I am very proud of our drivers, and they have all hit it hard in a comprehensive off-season testing programme. They are ready to race, and a strong and experienced team supports them. We have had so many inquiries about individual races from a variety of drivers that we decided to go ahead and put our brand-new 'house car' into the mix. Everything is in place for a very competitive season, and we look forward to representing the brand in competition."

Esayian joins TRG-AMR after finishing eighth in the 2013 GTS Drivers' Championship, while De La Torre makes his debut for TRG-AMR after gaining experience in karting and F3. He completed an aggressive testing schedule in a Vantage GT4 last summer and during the off-season to prepare for his professional racing debut. Regitz, meanwhile, returns to TRG-AMR after finishing eighth with the team at Mid-Ohio in 2013, the highlight of a limited schedule of seven events.
