If not, doesn't GM still own Detroit Diesel or did they sell that? Years ago you could get a GM medium duty with a CAT. Now that would be cool.
Detroit Diesel has been a wholey-owned Daimler brand since 2000. Fun fact: when you select between a Mercedes and Detroit Diesel in your new Freightliner, the only difference is the valve covers :)
CAT is no longer certified to sell on-highway diesels (they gambled on EGR instead of Urea-post-treatment, and never got it working right so they threw in the towel). The CAT-branded trucks are actually a Navistar joint-venture, but some of those even have a Cummins after Navistar was de-certified for a while, after they were caught cheating on their EPA test. It turns out Navistar never actually got their EGR system fully compliant either... They caught caught, paid the fines, and then had to dig out of the while using help from Cummins. First by supplying motors, then helping them quickly develop a Urea-based after-treatment.
