car has an adjusted ECU and a free-flow Suzuki Sport RHB31 turbocharger, as well as a different throttle body. Less than a hundred were built, although it continued to be available until the arrival of the next generation Alto. This model, without a backseat and with racing bucket seats in front, was classified as a van and accordingly received the CM22V chassis code, unlike the usual Alto Works. The undercoating and most creature comforts were deleted (although air conditioning remained an option) and the car sat on steel wheels, which made the car about lighter than a regular Works RS/R. Alto Hustle Suzuki also produced a version of the Alto, known as the Alto Hustle, with a raised roof behind the front seats. This was unusual in that it used a modification of the five-door Alto's body rather than a completely new body, allowing Suzuki to market it as part of the Alto family. Its appearance was similar to the Nissan AD Max van. The Hustle was short-lived, only being offered between November 1991 and October 1993.

The new Wagon R took over much of the more expensive Alto's market share, leaving the Alto to compete at the lower end of the market.

Front-wheel drive or full-time four-wheel drive were offered, in three- or five-door sedans or as a three-door van. The Works model was also reclassified as a sedan, as many advantages for light commercial cars had vanished. The tailgate and rear doors are still fairly angular, but the front was
