Returning with four body style choices, the 1999 Hummer produced by AM General can be ordered as either a two-door pickup-like style, a highly versatile wagon or a 4-door available as either a hardtop or open-top. Air conditioning, power windows and cassette player is found as standard equipment on the 1999 Hummer. With up to 16 inches of ground clearance, the 1999 Hummer's large tires are propelled by a 6.5 liter turbo diesel V-8 power plant connected through a 4-speed automatic transmission with overdrive. Mustering out 195 horsepower, the 1999 Hummer dramatically produces 430 pounds-feet of torque at only 1,800 RPM. Considered to have one of the most advanced four-wheel drive systems on the market, the Hummer is given additional handling creditability through two new standard features in 1999. For the first time, an anti-lock braking system is equipped while a new traction control system called Torstar 4 has also been added to the Hummer.
