The Vauxhall Corsa 1.3 CDTI ecoFLEX Start/Stop now achieves 85.6mpg with emissions of just 88g/km.  The Vauxhall Corsa –  and, for that matter, the Opel Corsa – has been revealed as the most economical car ever built by GM Europe after a series of tweaks has cut its already impressive fuel consumption. The Corsa 1.3 CDTI ecoFLEX Start-Stop )which, fortunately, isn’t emblazoned on the boot lid in full) can now squeeze 85.6 miles out of every gallon of diesel, which means emissions drop to just 88g/km. Vauxhall has had yet another play with their 1.3 litre diesel and fitted a variable displacement oil pump that delivered pressure to suit the load, had a tweak with the Corsa’s brain and filled low-viscosity oil in the gearbox  The result is in improvement of 7 per cent in economy over the current Corsa.
