Buick GNX

Onlookers could be fooled into thinking the Buick GNX was just another US coupe-styled car without a performance bias. That's without knowing it had help from ASC/McLaren in developing its turbocharged V6 engine, which put out a lot of horsepower and even bigger surge of torque. Initially, the car started life in I 978 as a Buick Regal with turbo V6 producing just 150hp (112kW). Four years later just 215 Grand Nationals (the 'GN' in the name) made it on the street and by 1984 power was up to 200bhp (149kW). Revised engine management and an intercooler pushed output to 235bhp (175kW) for 1986, then a year later came the association with McLaren and push to 276bhp (206kW) with huge torque. Although just 547 made it in this guise, the GNX was worth finding. It had modified uprated suspension for better handling, and a Panhard rod to increase cornering capability.
