Hyundai pulled the wraps off its R-Spec version of the Genesis Coupe at the Chicago Auto Show, a concept focused on the tuning market. The highlight is a 210-hp turbo'd inline-four that returns 30 mpg and a top speed of 137 mph. The Genesis Coupe R-Spec will be available mid-2010 with a base price of $23,750, or $3,000 less than the 2.0T Track model.
