VW To Extend TSI And Clean Diesel Range
January 3, 2007 4:44am CST
Volkswagen has announced that it will offer more petrol vehicles with (TSI) twinchargers and clean diesels under the label "Bluetec". Wolfgang Steiger, who heads the car maker's engine research division, said in Valencia, Spain, that "in the medium term we will convert all petrol engines to this (the TSI) concept." In combination with a turbo loader and compressor the TSI motor of even a small engine has the output of a six-cylinder with the fuel consumption of a four cylinder, Steiger explained. Developers at VW took a 1.4-litre motor from the Golf and fitted it to a 2.2 tonne VW bus where it has an output of 125 kW/170 hp which is still 50 per cent more than the current engine of 85 kW/115 hp. Fuel consumption is ten per cent less, according to Steiger. Steiger added that a TSI Passat engine was also combined with natural gas drive with an output of 110 kW/150 hp. The range was 400 kilometres on petrol drive and another 380 kilometres on natural gas drive. The technology was ready for serial production, he said. In order to comply with strict U.S. emission standards VW would launch the Jetta and new Tiguan SUV with Bluetec diesel technology as from the year 2008.
