What's the Cadillac ELR? Simply, a luxury spin on the Chevy Volt with improved power and two fewer doors. Yeah, that does sound pretty cool. Set for full debut at the end of 2013, the ELR was spotted dressed in rather incredible dazzle camo engaging in warm weather tests recently. Expected to compete with the Tesla S, this Caddy will push GM's commitment to plug-in hybrid rides and give the brand a slick option in an emerging market.
