Fiat 500D (no, it’s not a diesel)

 
In October 1960, shortly after the launch of the Giardiniera, an updated version of the 500 was revealed. The Nuova 500D replaced all previous Fiat models in a bid to rationalise the line-up. The upheaval was significant, with the sunroof and convertible roof variants a thing of the past; everything became unified with the new D version which (along with the Giardiniera estate car) made up the 1960 range of the Fiat Nuova 500.
 
Production
The early days of the 500D (October 1960 to November 1961) featured a number of differences to previous models in the range, notably lower trim levels and fewer mod-cons such as washer nozzles and ashtrays – but it did include plastic sun visors. Stowing luggage, so often an issue with smaller saloons of this period, was made easier with foldable rear seats, while the fuel tank became more efficient, changing from a flat to a cube shape. Over the next four years, the 500D underwent further improvements with different door moulds and various other small modifications. We would say that no expense was spared – but that wouldn’t be true.
