GM's Lutz confirms development under way on new Cadillac V12


DETROIT -- The AutoWeek March 26th issue reveals General Motors Holden division is well on the way to creating a new V12- powered Cadillac flagship.


In its cover story AutoWeek divulges that GM's Australian brand Holden is developing the hardware for an opulent V12-engined supersedan that draws its design inspiration from the 2003 Cadillac Sixteen concept car, a car that would return the high-line GM division as The Standard of the World. The story is written by Greg Kable, with reporting by Julian Rendell.


AutoWeek reports that the distinctively styled, rear-wheel-drive model is positioned at the top of the range, with a list of high-end features never before offered on a Cadillac, including the latest in crash avoidance and safety technology.

The car, dubbed Cadillac Twelve, would compete with Mercedes-Benz S Class, the BMW 7 Series and Audi A8, among others.


AutoWeek sources say the V12-powered flagship essentially mates two of the firm's 60-degree 3.6-liter V6 engines on a common crankshaft. The V12 will feature direct injection, cylinder deactivation and a state-of-the-art automatic gearbox to ensure competitive levels of power and economy.


GM global product vice president Bob Lutz, a longtime proponent of a luxury grand touring sedan for Cadillac, confirms development of the V12. All that remains is whether Lutz can convince GM's bean counters to put the Cadillac into production.
