Inflatable side-curtain airbags became optional on all models for 2001. All L-Series models were renamed. Instead of LS, LS1, and LS2, the sedans now were known as L100, L200, and L300, respectively. Wagons switched from LW1 and LW2 to LW200 and LW300. Models with 100 and 200 suffixes had a 4-cylinder engine, while 300 designated vehicles came with the 3.0-liter V6.
