Watch the Porsche 911 GT3 rear-steering system work

A handful of manufacturers have offered four-wheel steering in the past including Honda, Nissan, BMW, Mitsubishi, Mazda and, most recently, Acura and Porsche.

No sign of global auto meltdown at Tokyo Auto Salon

With more than 600 cars on display and a record number of exhibitors, nothing at the 2009 Tokyo Auto Salon tuner show hinted at the global economic downturn. As always, there was a great mix of styles, from hard-core, 1,000-hp, supertuned machinery to weird customized scooter tricycles. Auto manufacturers tried hard to capture the minds--if not the wallets--of the younger-than-30 crowd with customized versions of production cars, while tuners were busy persuading power junkies to choose them for their next engine modification.

Concept Car of the Week: Alfa Romeo BAT 7

This week sees the Concept of the Week title go to Alfa Romeo and Bertone for their collaboration on the Alfa Romeo BAT 7, the second addition to the BAT series that began in 1953 and finished in 1955. First seen at the 1954 Turin motor show, this wildly futuristic ‘dream' car came about after Alfa Romeo contacted Giuseppe "Nuccio" Bertone of the Bertone carrozeria to commission three concepts with the lowest possible drag coefficient. The cars were named BAT for "Berlinetta Aerodinamica Tecnica." Built upon the Alfa Romeo 1900 chassis, the BAT cars featured large rear bumpers and curved fins, and the concepts achieved a drag coefficient of just 0.19 - an impressive result.
