Back in July 2019, GM Authority reported that the upcoming Cadillac CT4-V Blackwing and CT5-V Blackwing ultra-high-performance luxury sedans will offer manual transmissions. More recently, Cadillac announced earlier this month that the six-speed manual gearboxes in both cars will use advanced 3D printing methods.
Additionally, Cadillac’s announcement included a statement that the manual transmissions to be used in the Blackwing models will be “both quieter and more durable” than those used in previous generations. This line in particular caught our attention. How exactly, we wondered, will this be achieved?
“We made changes in the design of the manual, added double isolation on the transmission lines and added a higher flow transmission pump (making it more durable from over heating),” GM spokesperson, Stefan Cross, has explained to GM Authority.
This inspires confidence. Manual gearboxes are inherently simpler than automatics, so one would expect them to be reliable. And it sounds like these ones will be reliable and refined, despite both cars’ considerable performance.
The 2022 Cadillac CT4-V Blackwing and CT5-V Blackwing will be the first production vehicles sold by General Motors with functional 3D printed components. In addition to the parts inside the transmissions, these will include two HVAC (heating, ventilation and air conditioning) ducts, an electrical harness bracket and, most obviously, a medallion on the shifter.
As we reported previously, both the CT4-V Blackwing and its CT5-V Blackwing will have transmissions supplied by Tremec, though as yet it is not clear exactly which transmission line will be used. Enthusiast drivers who prefer to let the gearbox make its own decisions about when to change gear will be pleased to know that both models will also offer GM’s 10-speed automatic as an option.
The 2022 CT4-V Blackwing and CT5-V Blackwing are due to go sale in limited quantities in the summer of 2021, both with optional magnesium wheels. Neither, however, will use the twin turbocharged 4.2L LTA V8 known as Blackwing engine, which used only in the now discontinued CT6 4.2TT Platinum as well as the CT6-V.
The CT4-V Blackwing will be offered with a twin turbo motor similar to the 3.6L V6 LF4 fitted to the Cadillac ATS-V, where it produced 464 horsepower and 445 pound-feet. The CT5-V will use a fabulous sounding supercharged Small Block similar to the 6.2L V8 LT4 last offered in the third-generation CTS-V, where it made 640 horsepower and 630 pound-feet of torque. With this amount of power available, it’s perhaps not surprising that the CT5-V Blackwing will have a top speed of over 200 mph.
