Late in the 1988 season, former three-time World Champion Jackie Stewart test drove the 100T at the Snetterton Circuit in Norfolk, England, which was Lotus's test track at the time. Within a few short laps he identified the car's basic problems. He said that the car lacked rigidity and its chassis was flexing, despite its carbon fibre and kevlar monocoque, and that the chassis couldn't handle the abrupt power delivery of the turbocharged Honda engine which made the car difficult to drive, a common complaint of Piquet and Nakajima, as well as the team's test driver Martin Donnelly. He also noted how cramped the driving position was and that the steering wheel and instrument panel were so close together that it made the panel almost unreadable. Stewart managed to spin and stall the car on one lap at the "Bomb Hole" corner when his driving glove was caught in the small space between the steering wheel and the top of the cowling and had to turn off the engine in order to be able to take his glove off to untangle it. He also said that the car was over-nervous and highly strung, and that "It was not a car that Nelson Piquet would have wanted to drive too many more times" and rated the car as "Perhaps one of the more disappointing cars I drove". When questioned about Stewart's findings during practice for the season ending Australian Grand Prix, Peter Warr refused to say what the Scot had reported, only stating that he had correctly identified problems which the team was already trying to fix.
