The Australian spec S-Coupe GT Turbo has been road tested by several Australian magazines, returning times of 9.2-9.3 secs for 0-100 km/h and 16.8 secs for the 0-400 m dash.
Hyundai says the Scoupe is the first production application for Garrett Automotive Products' new model T15 turbocharger. The turbo unit includes water-cooled bearings and housings and an integral wastegate.
The naturally aspirated Alpha boasts a 14% increase in power over its 1.5L Mitsubishi-designed predecessor, and the turbo produces 42% more power.
A "Lotus tuned" suspension was installed in both Base and LS models, while a slightly firmer strut valving was used in the GT. This, combined with the 2,176lb (987kg) curb weight made the car an interesting driving sport compact considering the low MSRP.[original research?]
The GT's EPA was 27miles per US gallon (8.7L/100km; 32mpg-imp) city, and 33miles per US gallon (7.1L/100km; 40mpg-imp) highway.
The 1991-92 "Base" models achieved 26miles per US gallon (9.0L/100km; 31mpg-imp) city and 34miles per US gallon (6.9L/100km; 41mpg-imp) Hwy for Manual Trans, and 25miles per US gallon (9.4L/100km; 30mpg-imp) city and 32miles per US gallon (7.4L/100km; 38mpg-imp) for Automatic.
The 1993-95 "Base" Alpha 1.5 engine models achieved 28miles per US gallon (8.4L/100km; 34mpg-imp) city 36miles per US gallon (6.5L/100km; 43mpg-imp) Hwy for Manual Trans and 25miles per US gallon (9.4L/100km; 30mpg-imp) City and 34miles per US gallon (6.9L/100km; 41mpg-imp) for Automatic.
The car was replaced by the Tiburon in 1997, with no sporty model available in model year 1996.
The Scoupe GT was Hyundai's first attempt at a sports car and featured South Korea's first domestically designed engine with a cast-iron block and crankshaft. The engine was made out of an aluminum head, aluminum pistons and steel connecting rods. A special compact pentroof combustion chamber design with central spark plug location has been incorporated to optimize engine efficiency. The engine utilizes a Robert Bosch GmbH electronic engine control system and a knock sensor.
