2014 Toyota Corolla loses Furia's flair, but theme remains

Thu, 13 Jun 2013

The all-new 2014 Toyota Corolla debuted last week with a fresh look, confirming that the Furia concept Toyota brought to the Detroit auto show was more than just an exercise in styling.

Fiat Panda Aria and Grande Punto Abarth SS concepts

Mon, 17 Sep 2007

By Guy Bird Motor Shows 17 September 2007 02:50 Aria goes green, Abarth gets sporty, 500 goes large… Fiat’s signature white stand featured both ends of the car spectrum: From the eco Panda Aria concept to a new even sportier version of the Grande Punto, the Abarth SS prototype. It arguably had the best show stand gimmick at Frankfurt too – a giant Fiat 500 model the size of a two-storey building housing a monorail on which punters could ride life-size 500 cars around its innards – entered through the giant 500’s wheel arch. Anyway… what about this eco Panda thingy… Oh yes, the Fiat Aria ‘concept’ is subtle like that.
