It's actually inconceivable, that a global concern could make such a faux pas, which didn't stop the motor-press from writing it up without giving it a moment thought. Thereby, almost everyone nowadays has a pocket calculator at hand.
To come straight to the point: The engine shown, can allegedly produce 320 Nm of torque at 1450-4400 RPM and, at the same time, have a maximum performance of 140 kW (190 HP). Precisely this is not possible. According to the formula:
320 Nm at 4400 RPM gives a performance of 147,4 kW (200,4 HP). In addition, considering that 4400 RPM is presumably not the nominal RPM, perhaps a somewhat higher performance must even be assumed. Who determined these values on a test-bench and, who published them unchecked, at the Vienna Motor Symposium of all places?
Let's collate the proclamations made there even further. The highly efficient cooling-management is partly standard already, also the exhaust manifold inside the cylinder head and the ten-speed double-clutch gearbox was already announced last year.
What is new, at least in the VW-concern, is a certain amount of turning away from 'downsizing'- in favour of the 'rightsizing' principle. They have finally recognised the advantages of Aktinson/Miller. Unfortunately, the press release is thus worded, that the effects of the statement are somewhat contradictory.
What is probably meant, is that the geometric compression ratio can now be increased, although under working conditions, the possible knocking combustion is not exploited. This occurs through a variable intake-angle of between 140° and 200°KW. This is provided by the Audi Valvelift System and is load-dependent.
Thus, small-stroke engines in larger saloon cars are not absolutely necessary. One simply gives the engine the filling of a small-stroke engine although still with a compression ratio that doesn't allow the efficiency to fall short. In the event of a higher load-demand, the engine management can quickly switch over to the customary filling and performance. The charging supports the fast change-over.
To close off with, we consider the use of OW-20 high-lubricity oil, to be worth mentioning. 05/15
