THE pound in your pocket goes further than you think thanks to new diesel technology, according to Peugeot after an economy test on Europe's most congested motorway.

A 1.4-litre HDi Peugeot 206 circumnavigated the M25 on just £5 worth of diesel. During the 120-mile journey, the car averaged 60mph and 73.3mpg, using 1.64 gallons of fuel, worth £5.57.
