Holden continues to test a variety of Cadillac models in Australia as questions over the brand being introduced go unanswered.

General Motors and Michelin have announced they’ll work together to develop the tyre maker’s Uptis Prototype airless tyre, with GM fitting them to a fleet of Chevy Bolts for testing.

News late last year that Holden would continue the Commodore nameplate on imported models was met with consternation, but that feeling could be short lived.

General Motors has retreated from Europe, selling off Opel/Vauxhall as well as its financial services arm to PSA Group.
