Earlier this year, GM Authority had the opportunity to get behind the wheel of the 2022 Cadillac CT5-V Blackwing, allowing us to record a short video of the ultra-high performance sedan reviving its supercharged 6.2L LT4 V8 engine. This also allowed us to line the CT5-V Blackwing up alongside executive editor Alex Luft’s personal ride of choice, a 2019 Corvette Grand Sport, for a fun rev-off between these two modern GM performance machines.
As Luft explains in the subsequent video of this all-GM rev-off, the 2022 Cadillac CT5-V Blackwing comes standard with a valved dual-mode exhaust, which will always be closed upon start-up. This is unlike the C7 Corvette Grand Sport, which can be started with the exhaust valves open for a louder, more aggressive sound upon start-up. The Corvette therefore sounds a bit meaner than the CT5-V Blackwing when it’s first started, however these two Small Block-powered beasts sound very similar in the upper rev ranges when they both have the valves opened.
One major difference with the CT5-V is that it produces a significant amount of cracks, burbles and pops once the driver lets off the gas, whereas the Corvette lets the revs fall in a smoother, more traditional manner. Additionally, the software in the 2022 Cadillac CT5-V Blackwing does not allow the sedan to free-rev above 4,500 rpm when the car is not in motion, whereas the Corvette will go all the way to the redline.
While both of these GM performance offerings feature a 6.2-liter Small Block, these engines are quite different in a number of ways. The 6.2L LT4 V8 engine in the CT5-V Blackwing is supercharged and produces 668 horsepower at 6,400 rpm and 659 pound-feet of torque at 3,600 rpm. The Corvette’s 6.2L LT1 V8, meanwhile, is naturally aspirated at produces 465 horsepower at 6,000 rpm and 465 pound-feet of torque at 4,600 rpm.

On these notes, I’d take the CT5-V Blackwing only for the interior space for wife and daughter. Love the back pressure tunes on the Cadillac.
Yeah, while my brother was buying his Matte Green CT4-V Blackwing at a local dealer, the salesman let me start up the blue CT5-V Blackwing they had parked next to it.
What a stellar sounding engine and exhaust system. The engine revs literally took my breath away. A sound I’ll never forget. But at $120k, it was just a dream.
A lot of vehicle MFGs don’t let there engines free rev. Not even my company 2014 2.5 liter Ford van.
The black wing really sounded restricted especially when he did the drive by. Sounded like the exhaust was being pushed through small holes. Probably from the catalytic converters
It’s a Cadillac, not a Mustang…
I would like to have BOTH of those cars.
Personally I prefer the sound of the Vette, but practicality of having a back seat, AWD, and a a few hundred HP more makes the Caddy a solid choice.
