The CTS-V promised to be more of the same; it uses a similar 6.2-liter supercharged engine, but here making a not-quite-as-ridiculous 551 lb-ft and 556 HP (to the ZR1’s 604 LB-FT and 638 HP). Also present are similar electromagnetically controlled shocks, promising both a smooth ride and, more importantly, mind-bending handling.
