Porsche Battery – a mere £1200

The rather expensive Porsche Lithium Ion Battery Car batteries have been roughly the same shape and size – and utilised basically the same lead-acid technology – for years.

Concept Car of the Week: Porsche Tapiro (1970)

By the late 1960s it was time for Porsche to create a new car that would replace its ageing entry-level model, the 912. Its sister company Volkswagen also needed a sports coupe to replace the Karmann Ghia and so the two brands joined together to develop what would become the Porsche 914.
