Halfshaft for 2021 Cadillac Escalades

NTN Corporation will provide the rear halfshafts for all 2021 Cadillac Escalades. To meet the demands of General Motor’s high production volume, NTN began the mass production of the halfshafts in the summer of 2020. The all-new 2021 Escalade went on sale in late-2020 in North America, with availability in other countries to follow.

Full-size SUVs have traditionally used a solid axle rear end that connects the left and right tires without the use of halfshafts. As demand for full-size SUVs has continued to grow, particularly in North America, the demand for improved ride comfort and vehicle dynamics has also grown. The all-new 2021 Cadillac Escalade has been engineered to accommodate an independent rear suspension (IRS) which transforms the driving dynamics of the vehicle, allowing each rear wheel to handle road conditions independently to enhance ride quality, steering responsiveness and overall driver control. This new IRS system also enables a lower interior floor to expand the Escalade’s interior roominess, and improve comfort by allowing easier access to the second and third rows, as well as creating a more natural seating position for third-row occupants.

To implement the all-new independent rear suspension, the Escalade required halfshafts that could provide the smooth transfer of power and refinement Cadillac buyers have come to expect, and also stand up to the 420 horsepower and 460 lb-ft of torque produced by the standard 6.2L V-8 engine. These rear halfshafts also need to operate flawlessly with the Escalade’s new and enhanced chassis technologies, including magnetic ride control, air ride adaptive suspension, and the electronic limited-slip differential, which deliver a responsive, precise driving experience and offer exceptional isolation from the road; and this is where NTN engineering comes in.

GM’s full-size SUVs are particularly popular in their segment in North America with a sales of approximately 300,000 units per year.
