Shelby GLH-S

The Shelby GLH-S is a limited production series of sport compact automobiles from the mid-1980s based on the Dodge Omni and modified by Shelby American. Later the name would also be applied to a Shelby modified version of the Dodge Shelby Charger. The GLH-S models all used intercooled turbocharged 4-cylinder engines.

1986

The 1986 Shelby Omni GLH-S was a modified Dodge Omni GLH, with changes made at the Shelby factory. They were retitled as Shelby Automobiles cars sold at select Dodge dealerships. GLH stood for "Goes Like Hell" and GLH-S stood for Goes Like Hell S'more.
Just 500 were made. Dash plaques using a three-digit serial numbering system were installed.
The Turbo I engine was modified with pre-production pieces from what would become the Turbo II inline-four engine. These changes included an intercooler, plus other changes to produce at 5300 rpm and a flat 175 ft·lbf torque curve. Not included were any of the durability changes to the short block of the 1987 Chrysler Turbo II engine. Luckily, the Shelby engines have proved to be reliable even without the durability enhancements of the production Turbo II. The GLH-S had a 0–60 mph acceleration time of 6.5 seconds and a 14.8 second quarter mile time. Top speed was 135 mph.

1987

The 1987 Charger GLH-S was based on the 1987 Shelby Charger. Shelby Automobiles purchased the last 1,000 Chargers built and they were shipped to the Whittier factory for modification. Shelby modified the Charger using the same pieces as the 1986 GLH-S, with some changes. The differences include a non-EGR turbo, Shelby valve cover, wider Shelby windshield decal, different and more extensive tape graphics package, no reference to Dodge on the outer body, black/white speedo overlay, a four-digit serial numbering system on the dash plaque, wider Mobil 1 plaque installed on the radiator support, and Shelby Centurion II wheels.
