Bruce Nunnally Posted November 28, 2014 Report Share Posted November 28, 2014 The next gen CTS-V is expected to use the new supercharged LT4 engine a la Corvette ZR1 with 8-speed automatic (only). In the ZR1 this engine was recently EPA rated at 13/23 mpg city/highway (Thanks CorvetteBlogger). The 2014 Cadillac CTS-V LSA / 6-speed auto is rated 12/18 city/highway. The previous Corvette ZR1 with the LS9 and manual (only) was rated at 14/21 mpg -- the equivalent CTS-V manual rated at 14/19 mpg. However, the new CTS-V will be lighter than the previous car by over 500 lbs, and will be much closer to the ZR1 weight. That might still leave the new CTS-V EPA rating at 12/21 mpg? City won't be better than the ZR1, and highway likely to be somewhat less due to aerodynamics...
