You've likely seen the #SaveTheManual movement online, as well as any number of opinion pieces on why the manual is dying, why it shouldn't die, and even why it should. But in a world where classic driver's tools like the Shelby GT500, Chevrolet Corvette, and even the Toyota Supra don't cater for manual enthusiasts from the factory, Cadillac of all brands remains committed to three pedals and a do-it-yourself shifter between the front seats. That's right, the Cadillac CT4-V and CT5-V Blackwing models will be arriving with a manual gearbox as well as the option of a ten-speed auto. We've already found out the manuals will be supplied by Tremec, but now, courtesy of Cadillac Society, we know how these 'boxes will be smoother and more refined than ever before.

Tremec gearboxes are notorious for their high-speed applications, but when dealing with high amounts of torque, they can sometimes lack the smoothness that's needed for a luxury marque like Caddy. In an interview, Stefan Cross, a spokesperson for the brand, gave further detail as to how the transmission would be "both quieter and more durable than the previous generation" - a statement from the press release that confirmed the shift-it-yourself approach to the Blackwing models.

According to Cross, changes have been made in the design of the manual with double insulation added to the transmission lines. Additionally, a higher flow transmission pump will supposedly make it more durable and help prevent overheating, all while improving shift quality and reducing noise.

Unlike its name might suggest, the Blackwing models will not utilize the eponymous engine that was a relatively short-lived engineering exercise. Instead, the CT4-V Blackwing will make use of a twin-turbo 3.6-liter V6 expected to produce in excess of 464 horsepower, while the larger CT5-V Blackwing will add a pair of cylinders in the form of a supercharged 6.2L V8, believed to be similar to the LT4. This motor will develop upwards of 640 hp, and enable the CT5-V Blackwing to eclipse the 200 mph mark. Both models are expected to debut next summer.
