Video: Buick Invicta

General Motor's Buick brand is blossoming in China, so the automaker chose the largest Chinese Auto Show this year to unveil its latest concept: the Invicta. Unlike the Riviera concept shown in Shanghai last year, the Invicta is slated for production soon given the level of refinement we saw when we viewed the car in Beijing. And unlike some market-specific new cars unveiled at the show, the Invicta will make its way to other markets across the globe.

Concept Car of the Week: Ferrari Pinin (1980)

Over the years, Ferrari has slowly built a reputation for the fact that any car that wears the prancing horse badge on its bonnet ought to be a design masterpiece. Everyone has their own personal favorite: 250 GTO, 250 GT California Spider, 330 P4, Modulo, Daytona, you name it...  Yet few would remember – or even know about – the odd ones, the ugly Ferraris hidden away, rarely allowed to see the light of day; a few rare cars that got brushed under the carpet as quickly as they appeared include the 365 GTC/4, FZ93 Zagato, the 408 Integrale and the Pinin. Most of them are the work of independent studios, long-distanced from Enzo's (dis)approval.

Porsche Panamera Sport Turismo concept (2012)

This is the new Porsche Panamera Sport Turismo concept car, unveiled on the eve of the 2012 Paris motor show. We hear that we won’t see a Sport Turismo version of the current Panamera, but this concept instead previews the facelift treatment that will be applied to Porsche’s four-door saloon as part of a mid-life refresh in 2013. And beyond that the Sport Turismo showcases a second bodystyle than will join the range when the Mk2 Panamera appears in late 2015.
