Aston Martin V12 Vantage roadster to start at $233,340

Aston Martin dropped the details of its UK-onlyV12 Vantage roadster on Tuesday, and the news is good. The new convertible will boast 509 hp and 420 lb-ft of torque from Aston's signature 6.0-liter engine. The roadster shares many of the technical features and specifications from the hardtop version, though some elements had to be changed to accommodate the folding soft top.

Concept Car of the Week: Heuliez H4 (1972)

With the H4, Heuliez set out into unexplored territories by offering a concept tailored to the needs of taxi drivers. If today's minivans are an integral part of our daily lives, this Peugeot 204-based H4 should be placed back in its original context in the early ‘70s, when this monovolume architecture still belonged to science fiction. Its dimensions are comparable to a Renault Modus although it's shortened by 140mm.

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.

But that probably has more to do with alternators replacing dynamos than the batteries themselves.
