http://gas2.org - The first 100 Cadillac CT6 PHEV cars are in the country and are on their way to dealer showrooms. All hybrid versions of the CT6 are built in China and imported to the US. The car features an electric only range of more than 30 miles from its 18.4 kWh battery. Hmmm….isn’t that the same size battery GM uses in the Chevy Volt? Yes it is, but it is not the same battery. Instead of being T shaped like in the Volt, the battery for the CT6 is more rectangular and fits between the rear seat and the trunk.
