When we think that the Audi biturbo diesel engine proposal just a rumor, the German automaker proof us wrong. The automotive world is entering the new dawn of diesel engine as more and more automakers developed efficient powerplant on the oil-burner energy. The first German automaker which patented the tri-turbo is BMW as the system is installed on the 3.0L V6 engine under the M performance division. As we think that other German carmakers are doing nothing, Audi steps up and officially introduced their 3.0L V6 TDI that uses the biturbo.
The additional turbo on Audi’s diesel engine is intended to boost up the total power output into 313 horsepower between 3,900-4,500 rpm with torque around 650Nm or 479 lb-ft. What makes the diesel engine efficient is merely not the diesel as autoevolution.com refers that the start-stop technology and thermal management system help reach the efficiency that Audi wishes for. The thermal management system responsibles for bringing the oil and coolant to maintain the operating temperatures.
The biturbo diesel engine will make a debut on the Audi A6 sedan and coupled to the automatic 8-speed tiptronic transmission and quattro AWD system. This way, the A6 sedan is able o hit 0 to 62 mph (100km/h) in 5.1 seconds with electronically limited top speed reaches at 155 mph or 250 km/h. The 3.0L BiTDI also uses what Audi refers as sound actuator that “transforms the typical TDI exhaust note into more sonorous roar which is closer to the output of a high-performance petrol engine”.
