Engine: 1.4-liter Ecotec turbocharged inline-4
What's cool: It's a four-seat coupe on the same rear-wheel-drive platform as the new Cadillac ATS, but could be priced for around $20,000. It has muscle-car design cues but fender flares and rounded front fascia lend a contemporary look.
Will it be built? GM sees a spot in its lineup for buyers who can't afford a Camaro but want something flashier than a Sonic or Cruze. A positive response from young people could push it into production.
