THE MUCH-VAUNTED EURO 6 EMISSIONS REGULATIONS ARE NOW WITH US, AND THEY ARE THE ONLY SHOW IN TOWN. WITH OVER SIX MONTHS OF ON-THE-ROAD EXPERIENCE IN THE UK, AND A LOT MORE IN EUROPE, IAN NORWELL LOOKS AT HOW THE MAIN PLAYERS APPROACHED THE ISSUE AND WHERE THEY AGREE TO DIFFER
FOG OF WAR
With the completion of various European press tests of trucks equipped with Euro 6 engines, it’s become clear that fuel economy is not the worry it was perceived to be a couple of years ago. Taking the major players’ vehicles on independent tests, the top and bottom performers have consistently been separated by as little as 0.5mpg. These figures are so close that the vagaries of testing may well have produced a different result on another day. But what these figures do tell us is that fuel consumption has not been a casualty of Euro 6. It’s also true that the latest emission legislation is not just about engines – a lot of other improvements have hitched a ride to fog the landscape, with transmissions being the most influential.
