Production changes For the second year of production, all 1993 Achieva models saw a reduction in power across the engine lineup due to changes made to comply with stricter emission requirements. This resulted in all engine outputs being lower for 1993, including the SCX which was down to for its final year (primarily due to exhaust port changes to the cylinder head). Other changes for 1993 included a revised front engine mount and changes to the Quad 4 block casting to address criticism for that engine's NVH characteristics. For 1994, a driver-side airbag was added as a standard feature, and the Buick-developed 3.3 L "3300" V6 was replaced by a Chevrolet-designed 3.1 L "3100" V6. In 1995, trim levels were reduced to one: SC coupe and SL sedan, divided into two groups, Series I and Series II according to equipment. The Quad 4 with and 3.1 liter V6 with were the only available engines for 1995; the other two engines from the previous year were dropped. The 1996 models added more standard features, include standard air conditioning and daytime running lamps, and a new dashboard featuring revised gauges and a passenger-side airbag. A Series III equipment level was added while the Series I was now only available on the coupe. The new base engine was a 2.4 liter four-cylinder "Twin Cam" that replaced the 2.3 L Quad 4. There were little changes other than reduced trim levels and options for the final two model years. The final model year for the Achieva was 1998, with the majority of sales going to fleet customers.
