Oldsmobile launched the Alero during 1998 for its 1999 introduction which replaced both the Achieva and Cutlass sedan models. The N-body platform underneath supported the Oldsmobile Alero which displayed late 1990s sedans' characteristic aerodynamic yet curving design. The available engine lineup for the Oldsmobile Alero consisted of the 2.4L LD9 inline-four from 1999 through 2001 and later switched to the 2.2L Ecotec L61 inline-four from 2002 to 2004 while the 3.4L LA1 V6 powered the entire production cycle. The vehicle acquired power from engines yielding 140 to 170 horsepower while featuring manual transmission setups with 5-speed Getrag systems (limited to four-cylinder models) and automatic transmission choices using 4T40-E or 4T45-E models. In the Oldsmobile Alero's production run the vehicle received a 107-inch wheelbase extending to a total length of 186.7 inches which delivered balance between handling and ride comfort. The Oldsmobile Alero models weighed between 2,997 and 3,124 pounds which offered functional characteristics to drivers. The Oldsmobile Alero model featured five seating positions with GX, GL, and GLS trim levels and included optional air conditioning equipment and CD players among its standard features. The Alero benefits from OEM genuine parts that preserve factory-reliability standards and operational performance while providing extended dependability to owners.
