Details for the new top-shelf CTS are still to be revealed, although reports suggest we could see power provided by GM’s 6.2 litre supercharged V8.
In CTS-V form, power is expected to land somewhere a little below the hero Corvette’s numbers, likely around the 445kW mark.
Other reports suggest GM may also look to its coming 4.5 litre twin-turbo V8 - previewed with last year’s Cadillac Elmiraj concept - but with power dialled well past the 370kW rumoured to be the ‘base’ output for that engine.
Whatever direction GM takes, it will be looking to better the 412kW offered with BMW’s M5 in standard form, and the 410kW of Mercedes-AMG’s E 63.
The recent ATS-V like previews GM’s intentions, with its own 340kW turbo six comfortably outdoing BMW’s 317kW M3 - although not quite matching the 350kW of AMG’s new C 63.
Watch for more on the new CTS-V to surface in the coming weeks.
