The BlueSport concept car by Volkswagen is aimed at whetting our appetites for the summer. Apart from a narrow and linear body, it is characterised by a mid-engine, offering room for turbocharged TDI or TSI engines. The 2-litre turbo engine gets from 0 to 60 in 6.6 seconds, with a top speed of 140mph. The consumption seems remarkable with such figures and according to VW it amounts to 55mpg of diesel fuel. The CO2 emissions are appropriately low: 113 grammes per kilometre.
