(Allpar exclusive information). Manual transmission versions of the 2009 Challenger R/T and SRT models will offer a feature that has previously only been available on the Dodge Ram, Jeep Commander, Grand Cherokee and the Liberty. The HSA feature assists the driver when starting a vehicle from a stop on a hill by maintaining the same level of brake pressure the driver applied for a short period of time after the foot has been removed from the brake pedal. The system will release the brake pedal in proportion to the amount of throttle applied. If the throttle is not applied within a short period of time after the foot has been removed from the brake pedal, Hill Start Assist will release brake pressure.
Trivia: Studebaker had Hill Start Assist (not by the same name) in 1936.
