The Atlantic previously was known under the codename Nina and is about the size of an Audi A5. Specifics weren't released, but the Atlantic is a plug-in hybrid with a BMW-sourced four-cylinder engine that acts as a generator to extend range. It's rear-wheel drive, with all-wheel power as an option. Pricing was not announced, but insiders expect the car to come in at less than $40,000 after tax credits. The strongly sculptured sedan has a domed hood, a split grille, sharp headlights and LED tail lamps. Coupe and crossover variants are expected.
