Why do manufacturers detune engines?
처리 내용
I'd be tempted to restate the question as "How do vehicle manufacturers decide what to tune for?" For the question as asked, there are a lot of possible reasons, and probably no way to know in a specific case unless somebody involved speaks up, but in general: To match the engine to a specific use case (as you suggested here). To find a balance between performance, durability, and marketing needs (detune in Sprinter to improve reliability, tune in E-class for marketing/performance). To fit into a particular regulatory class (in the US, for example regulations change with the load capacity of a vehicle). To meet insurance requirements (horsepower limits for example). To balance "fleet" requirements (another example from the US, makers are rewarded/penalized on maker's overall averages for fuel consumption and maybe for emissions as well, so tuning may get tweaked to manage this). Maintaining or adjusting a product "line" – a maker may want to have a "logical" progression of features or

Hello! I have not driven my car for a month and now have this noise. It is a 2016 V Jetta and normally in great shape.

Power seat - Whenever vehicle is started or shut off and the seat slides forward of back, the power seat makes an annoying, obnoxious noise… I thought something was stuck in the track but now I think it’s the motor going out. Guy at the local dealership said it just needed grease. He appears to be incorrect. Any thoughts? Thoughts?

A buddy and I were trying to replace his right front wheel hub, on his 2008 Chevy Impala LTZ. He described the engine size as 3900, I would think that means 3.9 liter, although I didn’t know there is a 3.9, I only know of the 3.8 liter and 3,1 Liter. One of the mounting bolts is so tight that the socket would not keep a grip on the bolt head, no matter how hard we tried to force the socket onto the bolt head. We had tapped on it as best we could with a hammer and metal rod, we heated the area with a torch, no luck. Of course, very little access to this bolt head, so impossible to use an impact
