Wether you like it or not, even when it is being more efficient and powerful, an engine working at higher temps and higher revs will have a lower life expectancy. Even if it is a high-tech engine, it is a matter of physics. Friction, force... take a toll on the engine components. That's why high powered engines need harder and stronger components to last longer. And that is also why low powered cars, with no turbo or any straining component will last longer than high-revving beasts. That is also why we see so many old cars still running fine against newer cars that squeeze more power from the engine using computers and turbos and what not, but sacrifice their longevity. Also, newer cars are made with lower quality components, compared to older ones. On a side note, more complex cars and engines tend to fail more sooner than later as there are more components which could fail (such as computers, fuses, cables, etc)Edited by pokerapar88 - 11/7/13 at 5:59am
