Dream Car Giveaway



  • According to John Schinella, Firebird's chief designer, the famed coupe became "more of a thoroughbred in 1985" with a "more aggressive" image and dramatic restyling.
  • Also new was a V-8 power plant with tuned-port fuel injection that was intended to deliver a 0-60 mph time in about 8.1 seconds.
  • Engine choices also included the base 151-cid (2.5-liter) four, the fuel-injected 173-cid (2.8-liter) V-6, standard ride/handling package now included all of the components of the former Y99 option except for special tires.
  • The basic appearance was similar to 1984
  • Optional in the Trans Am, this 205-hp V-8 produced 270 lb-ft of torque.
  • The Trans Am displayed
    • new aero-tuned rocker and quarter panel extensions
    • a new hood with twin louvers near the front
    • built-in fog lamps where the big air slots otherwise would be
  • An improved Y99 package included 15 inch wheels.
