    Chronology
    PredecessorOldsmobile Cutlass Calais
    SuccessorOldsmobile Alero

    The Oldsmobile Achieva is a

    GM N-body platform, which it also shared with its siblings the Pontiac Grand Am and Buick Skylark. The Achieva replaced the GM N-body Cutlass Calais
    after its final 1991 model year, and ended production after the 1998 model year.

    Overview

    The Achieva is a compact car produced by the

    V6. While a 5-speed manual transaxle was initially offered as the standard base transmission, most Achieva models were sold with 3-speed or 4-speed automatic transaxles. 1998 was the final model year for the Achieva, after which it was replaced in the Oldsmobile lineup by the Alero
    for the 1999 model year.

    Initial production

    Achieva SC coupe

    The Achieva was first seen as a concept car at the 1991

    Quad 4 engine standard that was optional on the S model. A 160 hp (120 kW) 3.3 L V6 engine was optional for the SL. The SC coupe had a standard 180 hp (130 kW) high-output Quad 4 with 5-speed manual transmission
    or a 3 speed automatic, with the 3.3 L V6 being an option.

    SCX

    The W41 coupe was introduced by Oldsmobile in 1991 on the Cutlass Calais and offered through 1993 on the Achieva. The Achieva SCX replaced the previous Cutlass Calais 442 W41 as the best handling, highest power output compact car in the Oldsmobile's lineup as well as being the last performance "W-Machine" Oldsmobile would offer. The SCX is a higher-performance version of the SC (sports coupe) and as such utilized the SC's deeper front bumper cover with standard fog lamps, lower body side cladding, rear bumper cover with dual exhaust tip cut-outs, as well as a unique W41-specific silver colored stripe around the lower body moldings, "W41" decals on the front fenders, and "Achieva SCX" decals at the leading edges of the doors. Other appearance changes for the SCX W41 package included the addition of a 140 mph speedometer in place of the standard 120 mph unit as well as a tachometer indicating the higher 7200 rpm red line.

    Performance modifications primarily differentiated the SCX from the SC models and were designed to make the SCX competitive for use in

    Computer Command Ride" (CCR) electronically adjustable struts and shock absorbers, as well as higher spring rates and bushing changes. (A similar CCR electronic suspension was also offered as an option on the Achieva SC as well as the platform-mate Buick Skylark and works similar to the systems offered on Cadillac and Corvette
    models of the time.)

    The SCX's powertrain included the highest output naturally aspirated

    calibration for the ignition and fuel systems that also raised the engine's redline to 7200 rpm. This engine was complemented by a unique version of the Getrag-licensed, GM-Muncie built Getrag 282
    five-speed transmission with special second and fifth gears as well as a different final drive ratio for quicker acceleration and better gearing to keep the engine in its power band.

    The production numbers for the Achieva SCX in 1992 totaled 1146 cars made with (6) C41 RPO code A/C-delete racing models as follows: (1) bright red, (2) medium garnet red, (1) aqua, (1) blue, and (1) white cars. The normal C60 RPO code models included (472) bright red, (42) medium garnet red, (218) black, (196) aqua, (50) neon blue, (151) white, and (11) gray cars.

    The 1993 SCX production totaled 500 cars produced including (5) C41 RPO code A/C-delete racing models as follows: (1) bright red, (1) aqua, and (3) white cars. The normal C60 RPO code models included (128) black, (191) bright red, (20) medium garnet red, (73) aqua, (8) neon blue, (70) white, and (5) majestic pearl cars.

    Production changes

    1993: For its second model year, engines offered a 5 horsepower (3.7 kW) reduction in power to comply with emission requirements, lowering the output of each engine. The SCX offered 185 horsepower (138 kW) for its final year, primarily due to exhaust port changes to the cylinder head. Other changes included a revised front engine mount and changes to the Quad 4 block casting to improve NVH characteristics.

    1994: A driver-side airbag was added as a standard feature,[3] and the Buick-developed 3.3 L "3300" V6 was replaced by a Chevrolet-designed 3.1 L "3100" V6.

    1995: 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 150 horsepower (110 kW) and 3.1 liter V6 with 155 horsepower (116 kW) were the only available engines for 1995; the other two engines from the previous year were dropped.

    1996: 1996 models included standard air conditioning and daytime running lamps. The dash was redesigned and shared with the Buick Skylark, 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.

    1997: Trim levels were simplified to Series I and II. The standard included automatic transmission, larger touring tires, power exterior mirrors, driver's side adjustable lumbar support, and standard traction control. 1997 models complied with side-impact standards, and the Series II Coupe received alloy cross-lace alloy wheels.

    1998: The final model year for the Achieva was 1998, with the majority of sales going to

    GMX130
    N-body platform that shared little chassis and platform architecture with the Achieva.

    Achieva production ended on December 4, 1997.[citation needed]
