Inspired by the 1954 Chevrolet Nomad Motorama dream car, the 2004 Nomad concept was based on GM's new Kappa rear-drive architecture. Power was provided by a turbocharged 210-hp Ecotec 2.2-liter four cylinder engine, linked to an electronically controlled five-speed automatic with finger-operated tap shifting. Inside, the black leather-trimmed 2+2 cockpit was accented by blue nubuck inserts and anodized blue aluminum gauges.
