A coupe based on Chevrolet's Impala sedan, Monte Carlo has front bucket seats for 5-passenger capacity. The LS model uses a 3.4-liter V6, the sporty SS a 3.8-liter V6; both come with automatic transmission only. SS has firmer suspension settings, a standard side airbag for the driver, and General Motors' OnStar assistance system; the last is optional on LS. Antilock 4-wheel disc brakes, traction control, and tire-inflation monitor are standard on both. Dual-zone climate controls and a rear-seat center shoulder belt are newly standard for 2002. To honor the late NASCAR driver, 3333 Monte Carlos equipped with the Dale Earnhardt Signature Edition option package were made available at midyear. Based on the SS, these cars include the High Sport option package and special exterior and interior trim.
