A SHARP-EYED Wheels reader has spied a pair of top-secret V6 Cadillacs that are so undercover that have been slipped into Australia via air. And under the bonnet, they could be V8s.

The two cars – marked as model year 2018 and sporting quad exhausts – were air-freighted into Melbourne under the cover of darkness yesterday. Like the development mule that was spirited into Australia a few months ago via the same flight path, these cars are destined for GM’s Holden-owned Lang Lang proving ground.

The fresh-look CT6 is an important model for Cadillac. The latest US data shows sales for the brand slumped almost eight percent in September, but grew globally with the CT6 up by almost 20 percent.
