The Shelby GLHS was a limited-production automobile from the late 1980s.
1986
The 1986 Shelby GLH-S was a modified Dodge Omni GLH sold under the Shelby marque. Just 500 were made.
Koni adjustable shock absorbers were specified, along with Shelby-made wheels and special tires. The Turbo II engine was modified with an intercooler and other changes to produce 175 hp (130 kW) and a flat 175 ft·lbf (237 N·m) torque curve. Performance was impressive, with just 6.5 sec needed for 0–60 mph (97 km/h) and 14.8 sec for the quarter mile (402 m) run. Top speed was 130 mph (209 km/h).
1987
The 1987 GLHS was quite different in appearance but similar in specification. Instead of the Omni, Shelby used the last 1,000 Dodge Chargers as a base model. Since the Charger and Omni were virtually identical apart from styling, Shelby carried over the engine and suspension modifications virtually unchanged.
Changes that were present were mainly a result of changes that Chrysler had made to the underlying Turbo I drivetrain between 1986 and 1987. Most noteably, the EGR was no longer present and the fluid used in the gearbox was no longer automatic transmission fluid but now 5W-30 motor oil. All Shelby GLHS vehicles left the factory with Mobil 1 oil in the engine and a sticker in the engine bay recommending its use. This sticker didn't "stick" very well and is usually missing except on very well preserved examples.
All 1987 Shelby Charger GLHS vehicles were the same colour, black. All had the same options which included a leather steering wheel and gearshift knob, air conditioning and a sunroof. There was also an allowance made for the laughable 85 mph (140 km/h) speedometer in the form of a sticker which extended the range of the speedometer to an indicated 125 mph (200 km/h). By the time the speedometer had wrapped fully around to the "5 mph" mark speed would have been 135 mph (217 km/h). Yes, the speedometer keeps going around. There was also a new version of the Shelby "Centurion" wheel that looked very similar to the Centurion wheels on the 1986 Omni GLHS but had the "blades" turning in the opposite direction.
