The first modern automotive accessory drive belt to operate without a tensioning device is making its debut on the 5.3-L V8 in the 2008 Hummer H3. The ribbed belt is sufficiently “stretchy” to be installed without permanent deformation, yet can maintain the required tension for as long as a conventional belt with a tensioner, while transferring the power required to operate the compressor.
