He ran a BMW and Porsche with no oil – which lasted longest? Crashes Misc by turboandstance - April 1, 2023 The time has come to lay their old BMW X5 & Porsche Cayenne to be laid to rest. So of course, they want them to go out with a bang! So they’re draining them of their oil, and going to see which lasts the longest! First up we have the Porsche. This Cayenne comes with a 4.5-litre twin-turbo V8 which can produce 335HP and 420Nm. Alongside it, we have the X5, which comes equipped with a 4.4-litre V8 which is good for 286hp and 440Nm. They won’t be driving anywhere, but the question is, which will last the longest? You’ll need to stick with Mat for this explosive finish! Leave a comment
