the most advanced direct-injection petrol<strong>engine</strong>s without the same compromisesin terms <strong>of</strong> emissions. Accordingly, the316ti is able to do without the elaborateand so far hardly reliable emissionmanagement technologies still requiredtoday on a direct-injection petrol <strong>engine</strong>.And it does not require sulfur-free fuellike a direct-injection petrol <strong>engine</strong>,achieving its superior fuel economy withproven l =1 <strong>technology</strong>, which allowsthe Valvetronic <strong>engine</strong> to run on allcommercially available grades <strong>of</strong> regularpetrol. In other words, the customerenjoys all the consumption-relatedadvantages <strong>of</strong> Valvetronic also whendriving in countries without anationwide supply <strong>of</strong> sulfur-free fuel.The consumption figures for the 316tinevertheless relate to the use <strong>of</strong> premiumfuel with an octane rating <strong>of</strong> 95 RON.Together with its 63-liter (13.9 Imp gal)fuel tank, the 316ti <strong>of</strong>fers a much longerrange than its predecessor, with extraurbanfuel consumption in the EuropeanEU test cycle <strong>of</strong> just 5.3 liters for 100kilometers (53.3 Imp gals). This meansthat the driver would only have to refuelafter a very significant 1,188 kilometersor 737 miles.Other AdvantagesAnti-knock control for runningon all fuel grades between 87 and99 octane.Maintenance-free ignition systemwith individual coils.
