The next generation S5 Coupe will be the recipient of Audi's wide-ranging use of aluminum and other light materials in its construction of its models. Because of this the 2014 S5 will cut its weight by up to 880 lbs (399 kg) in contrast to the current version.
Although there are other factors that certainly contributed to this amazing weight loss, the main factor however is the lightweight body construction and the size of the powerplant.
For instance, the present TT chassis is made up of 69 percent aluminum while the succeeding model year 2012 A6 will come with a higher percentage of lightweight materials in its body construction. The succeeding A4 and A5/S5 versions will likewise come with more aluminum in their design structures.
Car manufacturers have recognized the tough quality of these materials combined with their lightweight characteristics make them perfect for lowering the body mass of production cars thereby improving power and handling in the process.
However, Audi is going a step further by getting rid of its 333hp (245kW) 3.0-liter V6 unit which was used to replace the 4.2-liter V8 because the carmaker could not fit the two turbochargers in the cylinder banks of the engine bay.
To remedy this, a supercharger was used instead. But besides not using turbo technology for the succeeding S4/S5 duo they will also reduce the engine size employed. So it looks like its from a 4.2-liter V8 to a 3.0-liter V6 supercharged to something under 3.0-liter four-cylinder twin-turbo.We envision the 2.5-liter engine of the new TT RS brought to the limit for applications in the S4/S5.
According to the carmaker a prototype of the succeeding S5 finished the lap at the Nurburgring a whopping 8 seconds quicker than the present model partly because of a very low weight of 3,000 lbs. (1,361kg).
Meanwhile, as far as the next styling is concerned the Sportback Concept which was introduced early this year at the Detroit Auto Show is expected to be the production model and design leader for the carmaker, the latest A7 Coupe.
