Concept Car of the Week: GM-X Stiletto (1964)

With dreams of flying cars as the ultimate inspiration, General Motors designers in the ‘60s used every trick possible to make their creations appear as though they were floating – long, straight bodies, wheels pushed in and hidden away, large fins and lights that looked like rockets.

Lotus lusts after Lutz?

Lotus seem to be pursuing Bob Lutz The Lotus five year plan calls for the track day cars to make way for much more substantial and upmarket cars to become the force at Lotus; a move to become the Aston Martin East Anglia. Probably the first obvious move in this plan was to grab Dany Bahar from Ferrari last year (and Ferrari designer Donato Coco) and now Lotus are casting their net again to snare some big names to drive them forward. Top of the list is almost-octogenarian Bob Lutz who retired from GM – but certainly not from business – last year.

First Sight: Holden Torana concept

Holden has stolen the limelight at the opening of the Australian International Motor Show in Sydney, unveiling a ground-up concept car dubbed the Torana TT36. The concept revives a famous Australian nameplate from the 1970s - appropriate since, like the original Torana, it features rear wheel drive and a six cylinder engine. That's where the similarities end, however, as the new Torana's engine is an experimental 280kW/490Nm twin turbocharged version of the new global V6 Holden has begun manufacturing for various parts of the GM world and which will eventually be used by Alfa Romeo.
