In addition to the new face, the Insignia may be receiving new engines from the PSA Group as well as different infotainment and interior pieces. With all of these rumored changes, it is unclear how many (if any) will make their way to the Buick Regal. When PSA purchased Opel and Vauxhall, discussions were likely held about how the sale would impact the Buick brand but none of this information has been made public. Buick will have to turn to a different source for its future models so it will be interesting to see how the American luxury brand will proceed.
