There must be something in the water down in SupercarTown. The manufacturers have come over all Captain Sensible of late, swapping spoilers and titchy boots for hatchbacks with sufficient space for a pair of Cocker Spaniels. Porsche has now stretched a 911 to make the four-door, four-seater Panamera. With up to SOObhp on tap, it packs enough poke to scare you witless on a winding Alpine road. but has all the practicality of a Volvo estate. Thing is, to our eyes, Porker's latest looks a little too porky.
