Spencer Pumpelly is driving for Change Racing in the No. 16 Lamborghini Huracan GT3 in the WeatherTech United SportsCar Championship in the GT Daytona class.
The Huracán GT3 is based on the road car and shares many of its components, including a 5.2-liter V-10 engine that develops 585 horsepower. That power is driven through the rear wheels only via a six-speed sequential gearbox. The chassis is a combination of aluminum and carbon fiber and the curb weight is just 2,731 pounds.

Spencer, 41 years old from Mason Neck, Virginia, has competed at the top levels of sports car racing for nearly two decades. He has achieved numerous victories in the American Le Mans Series and GRAND-AM Rolex Sports Car Series, including two GT class wins at the famed Rolex 24 Hour at Daytona.
But Spencer did not get into racing the way most drivers do, competing in Go Karts at a young age. Instead, he didn’t start his professional racing career until after he graduated from James Madison University in 1998 with an economics degree.
Pumpelly’s big break came in 2006 with TPC Racing driving a Porsche GT3 Cup car where he took his first victory in the legendary Rolex 24 Hours at Daytona. Spencer added a second victory at the Rolex 24 Hours at Daytona (2011), a podium at the Mobil 1 12 Hours of Sebring (2011) and more than a dozen victories in all three categories driving for The Racers Group (TRG). Pumpelly made his first trip to the 24 Hours of Le Mans with Flying Lizard Motorsports in 2011 and was back again with them in 2012.

Spencer and Change Racing achieved their best finish so far this season at Canadian Tire Motorsport Park. Pumpelly and teammate Corey Lewis scored a top-five finish in the Mobil 1 SportsCar Grand Prix. Pumpelly qualified the Pertamina/Monster Energy Lamborghini Huracán GT3 third on the GTD grid and finished fifth.
“We had our hand forced by some of the yellows when they came out,” Pumpelly explained. “As a result we weren’t able to pit when some of the leaders did and had a green-flag pit stop at the end. I thought we had a pretty good car and our crew was spot on. Our pit work was great. Strategy wise, there’s always going to be some gambling, because you never know when the yellows are going to fall and it has a huge effect on how you run the race. It didn’t fall the way we wanted it to. It didn’t kill our hopes, but it took away a shot at the podium. It was an awesome job by everyone at Change. The car was fast, especially on old tires and we did everything right.”
