Pininfarina Hyperion

Pininfarina took the wraps off its latest bespoke creation at the Pebble Beach Concours d'Elegance this past weekend. Called the Hyperion, one of the Titans of Greek mythology, the car was created for collector Robert Hall by the coachbuilder's Special Projects Division. It was inspired by the proportions of cars from the 1930s.

Concept Car of the Week: IAD Alien (1986)

Established in 1976 as a railway and aeronautical engineering company, Britain's IAD (International Automotive Design) rapidly oriented its expertise towards the automotive industry providing services from design to chassis engineering and even small-scale production. By the mid-80s two concepts had been presented – the TRX and the Arrival – that showed innovative thinking and tastefulness but a little innocuous styling. In an attempt to attract both attention and more clients, IAD CEO John Shute asked his team to design a futuristic concept that was both innovative and different.

Chrysler Sebring

Chrysler has shown pictures of the 2007 Sebring, a mid-sized sedan that will enter production in America later this year. New from the ground up, the dynamic exterior borrows cues from the Crossfire in the front three-quarter, while a part-masked C-pillar helps accentuate the Sebring's arched cab, eschewing the 'chopped' look of the larger 300C. The urbane interior features an IP with a broad panel theme, reminding slightly of the Mercedes-Benz CLS/> It will be available from launch with the option of two V6 engines and, unusually, a new four-cylinder motor that produces 172PS from 2.4 liters.
