Don Nichols founded the company in California in 1968 under the name Advanced Vehicle Systems; the cars were called Shadows, designed by Trevor Harris and entered under the Shadow Racing Inc. banner. The first cars, the Mk.Is, were entered in the CanAm series with George Follmer and Vic Elford driving. The Mk.1 used very small wheels for low drag and was quick, but not the most reliable car in the field.
The team became more competitive the following year when the Harris car was replaced by a Peter Bryant design that owed some elements to his Ti22 titanium car. Jackie Oliver also arrived from that effort and finished eighth in the CanAm championship. Financial backing came from Universal Oil Products (UOP). Shadow came to dominate the shortened 1974 CanAm series with the DN4, by which point the works McLaren and Porsche efforts had left the series.
Towards the end of 1972, Nichols announced his intention to enter Formula One in the 1973 season with UOP-sponsored cars designed by Tony Southgate, who had previously designed the BRM that gave Jean-Pierre Beltoise victory at the Monaco Grand Prix. The team debuted at the 1973 South African Grand Prix with the Shadow DN1 chassis, fielding cars for Oliver and Follmer alongside a car for the privateer team Embassy Hill of Graham Hill.
For 1974, the team hired Peter Revson and Jean-Pierre Jarier. During a practice run for the 1974 South African Grand Prix, Revson was killed by a suspension failure on his DN3 car. He was replaced by Tom Pryce.
The DN5, driven by Jarier, gained pole position in the first two Grands Prix of 1975 but suffered mechanical failure in both races. The DN5 and most other Shadow Formula One cars used Ford Cosworth DFV engines producing around 490 bhp. Later in 1975, Jarier also drove the DN7, fitted with a Matra V12 engine producing around 550 bhp; the wheelbase was substantially lengthened to accommodate the larger French powerplant, but budgetary issues meant the Matra-powered DN7 remained a one-off. Pryce won the non-championship Race of Champions that year.
Pryce died in an accident involving a marshal at the 1977 South African Grand Prix. Marshal Frederick Jansen Van Vuuren had been running across the track to extinguish a small fire on the other Shadow car; Pryce was unable to avoid the collision because he was unsighted behind the March of Hans-Joachim Stuck. Pryce struck Van Vuuren at speed and was killed by the fire extinguisher Van Vuuren was carrying. Before Pryce's car came to a stop it hit Jacques Laffite's Ligier, causing both cars to crash into the barriers. Van Vuuren's injuries were so severe he could initially only be identified by his absence from a marshals' meeting after the accident.
The team replaced Pryce with Alan Jones, who won the team's only Grand Prix at the Austrian Grand Prix that year. Renzo Zorzi lasted only two more rounds after the South African Grand Prix before being replaced by Riccardo Patrese at Monaco.
After the 1977 season Shadow entered a sharp decline. Jones left to join Williams for 1978. A majority of the team's staff and sponsor Franco Ambrosio departed to form Arrows, taking the young Patrese. Despite sponsorship from Villiger tobacco and the signing of Clay Regazzoni and Stuck for 1978, results were poor: three fifth-place finishes, two by Regazzoni and one by Stuck.
For 1979, the team employed Jan Lammers and Elio de Angelis. Their only points finish that year was de Angelis' fourth place at the 1979 United States Grand Prix. De Angelis left for Lotus after the season; Lammers replaced Stuck at ATS.
In 1980 the team was absorbed into Theodore Racing. Shadow's first ground-effect chassis was largely uncompetitive, qualifying only once in seven races across three drivers: Geoff Lees (who provided their sole qualification at the South African Grand Prix), David Kennedy, and Stefan Johansson. Sponsorship dried up and after the seventh of the year's fourteen races, Teddy Yip wound up the Shadow team.
In 2020, Italian entrepreneur and racing driver Bernardo Manfrè revived the Shadow Racing Cars name as an Italian car tuning and luxury brand. Plans were announced for a hypercar called the Hypercar Shadow and a modified Dodge Challenger variant known as the Shadow DNM8. Shadow entered the NASCAR Whelen Euro Series in 2020 under Swiss-based team 42 Racing, fielding Manfrè in the No. 17 Ford Mustang alongside Luigi Ferrara and Francesco Garisto in the No. 42 Ford Mustang. The team missed the second half of the 2020 season after members tested positive for COVID-19 ahead of both the NASCAR GP Croatia at Rijeka and the Valencian Super Speedweek at Valencia.
The team returned in 2021 with a Shadow DNM8-based chassis — the first racing chassis entered under the Shadow name since the Shadow DN12 was last raced at the 1980 French Grand Prix. Francesco Garisto finished fifth in the EuroNASCAR 2 class that year after two podium finishes at Most and Vallelunga. Shadow and 42 Racing parted ways after 2021; from the 2022 season the team competed as MK1 Racing Italia, moving its base from Lugano to Bollate in Italy. Manfrè and Garisto were retained while Claudio Remigio Cappelli and Alfredo de Matteo were signed to the No. 16 car, with technical support from Race Art Technology.
