2022 Cadillac CT4-V, CT5-V Blackwing to Get Magnesium Wheels

Cadillac has simply introduced that the eighth most ample factor within the earth’s crust—magnesium—can be used for wheels on the upcoming Blackwing variations of the  CT4-V and CT5-V, and Cadillac notes that “2022 CT4-V Blackwing and CT5-V Blackwing would be the solely GM merchandise to supply magnesium wheels within the close to future.” Fascinating.

First, let’s concentrate on the magnesium alloy itself. Magnesium is each very robust and really gentle—it has the best strength-to-weight ration of any generally accessible metallic—and that makes it an excellent candidate to scale back unsprung mass in automobiles with out compromising the integrity of the wheels themselves. Porsche has used magnesium wheels on a few of its automobiles up to now (the 918 Spyder and most up-to-date 991 GT2 RS come to thoughts).

Not solely is it lighter and stronger than aluminum, it is also going to be extra unique. No different GM merchandise can be getting solid magnesium wheels, in response to Cadillac. Do not let this deject these of you who’re eagerly anticipating the following Corvette Z06, for there may be one other materials that is very robust and really gentle—carbon fiber.

Whereas the Shelby GT350R and the GT500 with the carbon pack have introduced carbon fiber wheels to the world of American efficiency automobiles, Cadillac is sticking with good quaint alloys for the final word model of the CT4 and CT5, and that is superb. Nevertheless, this does depart the door open for the next Corvette Z06 (and perhaps the following Camaro Z/28, assuming there may be one) to essentially up its recreation with a set of carbon fiber wheels. They’re costlier to construct and exchange than magnesium is, however the Vette is little question going to be a costlier automobile.

We’ll have to attend till summer season of subsequent 12 months to get the total particulars on the Blackwing automobiles, however count on the magnesium wheels to be an expensive and uncommon choice when the automobiles to lastly break cowl.
