Volvo insists they won’t lose any go or refinement, while beating their predecessors’ economy and emissions figures. The bigger-selling diesels have fuel injection systems that work at very high pressures and every injector has a computer, calculating the amount of fuel each of the engine’s cylinders needs. Volvo claims that in the V60 D4 SE estate the result is a car that gets to 62 in 7.6 seconds, reaches 139mph and produces 113g/CO2.
