Effects of curvy roads

Curves are sometimes included in new street construction where flat land permits straight. Surely, curves increase tire wear and increase fuel consumption. I have been unable to find data regarding this. 199.168.104.122 (talk) 13:17, 18 December 2019 (UTC)

Dead link in reference 18 — replacement available

This edit request has been answered. Set the |answered= parameter to no to reactivate your request.

Reference 18 (http://s3.amazonaws.com/mark_tranchant/images/tdi-bsfc.png) is a permanent dead link, tagged as such in the article. It is cited twice in the Engine speed and gear selection section as a visual reference for a typical turbo-diesel BSFC map.

A replacement image is available at: https://fuelmarble.com/images/turbo-diesel-bsfc-map.jpeg

It illustrates the same concept — RPM vs torque efficiency contours for a small turbo-diesel — and is hosted on a permanent URL. I have a connection to this site so I am flagging here rather than editing directly, per COI guidelines. Bizbiz2023 (talk) 10:21, 12 March 2026 (UTC)

The user below has a request that an edit be made to Energy-efficient driving. That user has an actual or apparent conflict of interest.
The requested edits backlog is very high. Please be extremely patient. There are currently 415 requests waiting for review.

Please read the instructions for the parameters used by this template for accepting and declining them, and review the request below and make the edit if it is well sourced, neutral, and follows other Wikipedia guidelines and policies.

Thank you for the correction. Resubmitting with the correct template.

Reference 18 in this article is a permanent dead link:

^{[dead link]}

This is cited twice in the "Engine speed and gear selection" section as a visual reference for a typical turbo-diesel BSFC map.

A working replacement is available at:

https://fuelmarble.com/images/turbo-diesel-bsfc-map.jpeg

The image shows the same concept — RPM vs torque efficiency contours for a small turbo-diesel — and is hosted on a permanent URL. I have a connection to this site and am therefore requesting this edit rather than making it directly, per Wikipedia's conflict of interest policy.

Please change:
