Oldsmobile Achieva - Production Changes

Production Changes

During 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 engines and trims levels 5 horsepower (3.7 kW) lower for 1993, including the SCX which was down to 185 hp 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 one of the standard features. The Buick-developed 3.3 L "3300" V6 was replaced by a Chevrolet-designed 3.1 L "3100" V6. All 1994 models through end of production have automatic transmissions.

In 1995, all Achieva trims were reduced to one: S coupe and sedan, which is divided into two groups according to equipment: Series I and Series II. Driver-side airbag, anti-lock brakes, and an air conditioner are standard to every version. The Quad 4 with 150 horsepower (110 kW) and 3.1-liter V6 with 155 horsepower (116 kW) were the only available engines for 1995, the other two from the previews years were dropped.

The 1996 models add more standard features to include standard air conditioning, daytime running lamps, and a new dash panel featuring revised gauges with passenger-side airbag. The new base engine was a 2.4-liter four-cylinder "2.4L Twin Cam" that replaced the 2.3-liter 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. The Achieva was complemented at the end of its production run by the slightly larger Cutlass which overlapped Achieva production from 1997 to 1999. Both models were replaced in the Oldsmobile lineup by the Oldsmobile Alero in 1999. The Cutlass and Alero were built on a new front wheel drive GMX130 N-body platform that shared little chassis and platform architecture with the previous Achieva.

Achieva production ended on December 4, 1997.

Famous quotes containing the word production:

    The repossession by women of our bodies will bring far more essential change to human society than the seizing of the means of production by workers.

    The myth of unlimited production brings war in its train as inevitably as clouds announce a storm.
