The first prototypes were built in 1989 and went into testing in mid-1989. In August 1990, production preparation began, with early production "builds" being constructed during late 1990. The first series production models were assembled in May 1991, with SE variants being launched in July 1991. This generation hosted quite a few Bonneville firsts, becoming quicker and considerably safer. One of the most notable improvements over the previous generation was that the Bonneville SE now came standard with a driver airbag and was the first General Motors product equipped with a passenger airbag, while ABS was available as part of the sport appearance package. The SSE models came with standard ABS and traction control.
