Buick's Insignia for America and China
* All the car launches from Detroit * New Mercedes E-Class and Jaguar XFR * Toyota Prius, too...
There won't be many British car buyers familiar with the Buick LaCrosse, but the chances are that the car it's based on will become a best-seller over here.
That's because the updated executive saloon is based on the new Vauxhall Insignia.
However, it has received a substantial reworking, not least because it is seen as a Lexus rival by its makers.
That means reworking the ride to be super-smooth, and ensuring the cabin is both refined and ultra-quiet.
There's also clever technology that will be more familiar to Insignia owners, including a brake assist function, a head-up display and a blind spot alert system
There are two engine options: a 256bhp 3.0-litre V6 with 214lb ft of pulling power, and a 276bhp 3.6-litre V6 with 261lb ft of pulling power.
It will go on sale in autumn 2009, both in the US and China, where Buick is a major brand.
