Groundbreaking: The Audi RS 5 TDI concept

Posted on 18. Jun, 2014 by in Audi Canada

“25 years ago, Audi launched a initial TDI on a market, essay a initial section of an fast success story,” says Prof. Dr. Ulrich Hackenberg, Board Member for Technical Development. “Our latest creation is a electric turbocharger, that serve improves not only scurry times and pulling power, though also efficiency. This record illustrates a possibilities harbored by 48-volt electrical systems, that we are now building for use in prolongation vehicles.”

The V6 biturbo in a Audi RS 5 TDI judgment produces 283 kW (385 hp); from 1,250 to 2,000 rpm it transfers 750 Nm (553.2 lb-ft) of torque to a crankshaft. The red-line is during 5,500 rpm. The supplemental electric turbocharger provides for towering appetite when starting off. An electric engine replaces a turbine circle and accelerates a compressor circle to over 70,000 rpm in a few hundredths of a second. The empty turbochargers also yield as most as 2.4 bar of relations boost pressure.

This multiple enables a Audi RS 5 TDI judgment to scurry from 0 to 100 km/h (62.1 mph) in only 4 seconds. The 200 km/h (124.3 mph) symbol is reached in reduction than 16 seconds, and tip speed is 280 km/h (174.0 mph). The normal fuel expenditure of reduction than 5.3 liters of diesel per 100 kilometers (less than 140 grams CO2 per kilometer) (44.4 US mpg/225.3 g/mi) papers a superb efficiency.

Recuperation is a primary source of a expostulate appetite for a electric turbocharger. To broadcast this energy, a RS 5 TDI judgment uses a apart 48-volt electrical complement that is connected to a required 12-volt electrical complement around a DC/DC converter. The appetite is stored in a compress lithium-ion battery. The advantage of 48-volt electrical systems is that they capacitate a delivery of incomparable amounts of energy. This creates them an critical miracle in a Audi foundation strategy.
