Con sorpresa, posto un estratto dall'ultimo numero dell'Economist:
The rebirth of the diesel engine
Automotive technology: Electric and hybrid cars are being given a run for their money by an unlikely competitor: a range of advanced diesel engines that set new standards in performance and fuel economy
Later this year Americans will get their first chance to experience what a really advanced diesel is like?and why Europeans opt for diesels over hybrids, plug-in electrics and even petrol-powered cars. The leader of the new pack is the Mazda 6, with the choice of either a 2.5-litre four-cylinder petrol engine or a 2.2-litre turbo-charged diesel. The diesel has more than 30% better fuel economy and provides oodles more pulling power. Good as the petrol version is, motorists who choose it over the diesel will miss out on a lot. And Mazda is not the only carmaker with an advanced diesel in the works. Among others, Mitsubishi Motors has been selling cars with a new generation of 1.8-litre and 2.2-litre diesel engines in Europe since 2010. Hedging its bets on hybrids, TOYOTA has also been testing several radically new diesel designs.
§§§
With its OLD 1.4-litre diesel engine, the Volkswagen Polo currently holds the record for being the most frugal non-electric car in Europe, with a fuel economy on the combined cycle of just 3.8 litres/100km (equivalent to 61.9 miles per American gallon). The Toyota Prius hybrid? A lowly 20th in the league table of the most economical fuel-sippers, with 4.2 litres/100km, along with higher emissions of carbon dioxide. The 19 cars having better fuel economy than the Prius hybrid are all clean diesels.
