Electramotive later became Nissan Performance Technology Inc. (NPTI) in 1990, finally retiring the GTP ZX-Turbos once the new NPT-90s were completed halfway through the season.
Electramotive founder Don Devendorf and co-driver Tony Adamowicz took the car to eleventh place, seven laps down from the race winner.
The newly named GTP ZX-Turbo made its season debut in the streets of Miami, but this was followed by a string of problems in the future rounds.
The final race of the season in the streets of Columbus would see a distant fifth place, earning Nissan seventh in the constructor's championship with their points total.
This earned the GTP ZX-Turbo its maiden win at Miami, defeating a Porsche 962 by eleven seconds after three hours of racing.
Nissan's success would be short lived though as the next rounds at Road Atlanta and Riverside would see the car failing to finish due to clutch failure and an accident respectively.
Although Nissan managed to take an improved fifth in the constructor's championship, they still earned only a sixth of the total points that champion Porsche had.
Starting with a disappointing eighth at Miami, the GTP ZX-Turbo would begin its streak of successes that would help the car become a threat to the top teams.
Unlike previous years, this success would continue as another victory was taken at the next round at the streets of Palm Beach, then Lime Rock Park, Mid-Ohio, Watkins Glen, and Road America.
Wishing to overcome their narrow defeat in 1988, Electramotive and Nissan would fight hard to win the elusive championship in 1989.
At the shorter Miami round, the GTP ZX-Turbo would return to its winning form from the previous season, once again defeating Jaguar.
However, at the 12 Hours of Sebring, the GTP ZX-Turbo would score a surprise result, with Chip Robinson, Geoff Brabham, and Arie Luyendyk taking the race victory by two laps.
However the GTP ZX-Turbos were back at Topeka with the top two positions, beginning another short streak through San Antonio and Sears Point.
With ten victories in comparison to Jaguar's three, Nissan was able to easily win the constructor's championship, the first time anyone besides Porsche had won it since the GTP class had been created in 1983.
As the defending champions, Nissan realized that the aged GTP ZX-Turbo was now the prime target of all other competitors, leading them to begin development on the car's replacement.
Debuting at a time when Nissan was phasing out the Datsun brand in the United States, the GTP ZX-Turbo was used by the company to promote their ability to produce sporty, advanced cars.
This led to the GTP ZX-Turbos being used in television and print advertisements for the whole Nissan brand, but also specifically the 300ZX with which it shared its engine.
