Greg Sacks (born November 3, 1952) is an American former stock car racing driver. He is married and has three children. He lives in Ormond Beach, Florida. He and his sons are partners in Grand Touring Vodka. Sacks has spent most of his career as a research and development (R&D) driver for many NASCAR teams. He won the 1985 Firecracker 400 at Daytona International Speedway acting as an R&D driver for DiGard Motorsports. Modifieds Early in his racing career, Sacks was a successful driver in what is now the NASCAR Whelen Modified Tour. Competing from 1980 to 1983, he won 17 races at Stafford Motor Speedway. 1992 was an especially good year for him, as he won the track championship that year, as well as the Spring Sizzler, The Ferrera 100 and the Fall Final. Greg also won the Dogwood Classic at Martinsville Speedway, the Bud Classic at Oswego Speedway, the Thompson 300 at Thompson International Speedway, the World Series of Asphalt at Thompson Speedway and the Race of Champions at Pocono Raceway. In 1983, he made his NASCAR Winston Cup Series debut in the Pepsi 400 at Daytona in the No. 5 car owned and sponsored by his father, Arnie. He only completed nineteen laps until experiencing engine failure, finishing 38th out of 40 cars. Sacks competed in four more events that season, posting a best finish of 17th in the Champion Spark Plug 400 at Michigan International Speedway, the only race he finished that year. Success in the 1980s In 1984, Sacks made a full attempt at the NASCAR Winston Cup Series, once again in a car owned by his father, only now it ran as No. 51. Sacks made 29 out of the 30 races, finished 19th in points and runner-up to Rusty Wallace for the NASCAR Rookie of the Year award. 1985 got off to a rough start for Sacks. After the first four races, his father's team folded. Seven races later, Sacks was able to drive the No. 49 car owned by 1966 NASCAR Rookie of the Year James Hylton. Before the Firecracker 400, DiGard Motorsports asked Sacks to drive their R&D car. Sacks qualified ninth and defeated pole-sitter Bill Elliott to earn his only NASCAR Winston Cup Series victory. The win was considered to be one of NASCAR's biggest upsets, as Sacks's car was only scheduled to run a set number of laps before
