When I trekked my old car regularly, the gauges helped tell me when I'm pushing too hard and it's time to take my car in to rest.
Then they tell me when its cooled sufficiently to take it out again.
Some have turbo boost gauge so they know when it's about to kick in.
Then there is the air/fuel gauge... that helps tell when you are using the accelerator too much or too little (running too rich, or too lean - petrol/air mix).
Some put in a volt meter - you can monitor your battery here. I don't think a lot of cars come with this as a standard.
So... there is a point to the gauges, even if it's just to turn a hyundai into a ferrari in the owner's mind.
These days my car only has a small suction cup clock... and a cow decal.

Hi,
I see some 'sports' car looking cars got installed with several small meters in addition to default meters like speedo, tacho etc. You know, those small sized meters like a set of 4 or 5 lined in a row on the dashboard.
I just like to know, if you also happen to have them, what are they for?
What are the benefits to have them? make the car faster?

and small engine cars that installed with large sports car exhaust. like 1.5 litre ones installed with sports car category exhausts.
Does this mean they need to 1st increase their engine power before can install those? How does this improve car speed or performance, if any?
thanks in advance!!
