  • 1. SUZUKI MAKES A SWIFT MOVE TOIMPROVE FUEL ECONOMY ANDREDUCE CO2 EMISSIONSSuzuki GB PLC is introducing a new engine for its ever popular Swift model. Plannedfor introduction early next year, the new 1.2-litre petrol unit incorporates Suzuki’slatest technology that utilises twin fuel injectors for improved fuel economy.The new technology, known as Dualjet, has resulted in Swift attaining 65.7mpg onthe EC Combined fuel consumption cycle, representing an impressive 9.2mpg or 16per cent improvement over the current petrol engine. Another benefit of Dualjettechnology is reduced CO2 emissions of 99g/km, meaning that Swift models with thisengine are now exempt from VED (Vehicle Excise Duty) charges. Even fewer trips tothe fuel pumps and zero VED will equate to a saving of up to £175 per year for anaverage mileage owner.Utilising Dualjet technology that positions the fuel injectors very close to the engineinlet valves allows for a finer fuel atomisation (or mixture) which in turn provides amore effective transfer into the cylinder. Internal modifications to the engine includethe use of a new type of inlet port and combustion chamber with other mechanicalparts also modified to reduce frictional losses and facilitate smoother running.The piston crowns have also been modified with a slight bowl shape to achievehigher air turbulence inside the cylinder, and the pistons have cooling oil jets to helpreduce internal temperatures. Additionally, a new type of Exhaust Gas Recirculation(EGR) system is used which helps avoid abnormal combustion or ‘knocking’. Thesemodifications have resulted in a higher compression ratio of 12.0:1 versus 11.0:1 forthe current engine.The maximum power output is 90PS versus 94PS for the current petrol engine with aslightly increased torque figure of 120Nm at 4,400rpm versus 118Nm at 4,800rpm.Other modifications include slight alterations to gear ratios for greater flexibility onthe road, and the addition of Engine Auto Stop Start (EASS). (A full specificationsheet is attached).The new Dualjet technology for Swift will initially be available as an optional enginechoice on SZ4 two wheel drive models and will cost around an additional £500. Finalprices will be confirmed closer to introduction.Global sales of Swift have now passed the four million mark since launch in 2004 –eighteen months after the celebration of three million units. Launched in the UK inMay 2005; more than 90,000 Swifts have been sold and now account for around 30per cent of the UK sales mix.
