This autumn, the new 4.2 litre V8 "chain-driven engine" celebrates its premiere in the Audi allroad quattro 4.2. In this engine, the toothed belt has been replaced with a timing chain, as a result of which the camshaft drive has been relocated to the rear of the engine. This arrangement means that the chain is subjected to less strain and a duplex chain can therefore be dispensed with. Thanks to the removal of the toothed belt, the already compact V8 is shortened by a further 52 millimetres. This power plant will also be fitted in the S4, which will be presented at the end of the year, and will then gradually replace the toothed belt-driven engine.
