With the premiere of the Cadillac CTS and promise of overdue diesel engines on the way for Europe, General Motors Corp.’s global brand will try to resuscitate sales overseas.

The ’08 CTS sedan is set to bow at next month’s Geneva auto show.

U.S. production of the new CTS is to begin this summer at GM’s Lansing (MI) Grand River plant, for sale in the U.S. and Europe in the fall.

Cadillac’s redesigned CTS is powered by a new 300-hp 3.6L V-6. A diesel engine also is expected for Europe.

The Cadillac BLS gets a refresh in the form of the BLS Sport. The Europe-only BLS will feature 18-in. wheels and a lowered sport suspension in the Sport.

The 150-hp engine will offer a direct-injected, common-rail turbodiesel fitted with a particulate filter. All BLS models are equipped with a 6-speed manual transmission.
