What is it?[edit]

The article does not actually answer the question "What is KERS?" (and how does it work?) —Preceding unsigned comment added by (talk) 22:22, 11 January 2011 (UTC)

I came to this talk page to raise the very same point. I looked for Kers on Wikipedia to know what is it and I kind of still don't know. I know it's a magical box that weights 25kg and makes the car run faster. Just that. --Damiens.rf 18:46, 26 March 2011 (UTC)
I've added a basic description to the lead. It's open to improvement. DH85868993 (talk) 05:51, 27 March 2011 (UTC)

A kinetic energy storage device was demonstrated on the BBC's "Tomorrow's World" decades ago where it was proposed for use in busses which have to perform continual stop-start manoeuvres. In this case fuel saving was the objective rather than performance, but basically it was the same idea where braking energy rather than being dissipated was stored in a flywheel for re-use. Perhaps someone might like to add the various types of these devices, exactly how they work and when they first appeared.

Confusing/contradictory sentence[edit]

One of the main reasons that not all cars use KERS is because it adds an extra 25 kilograms of weight. While not adding to the total car weight

It adds 25kg, but doesn't add to the total car weight? What does this mean please? David (talk) 14:19, 17 April 2011 (UTC)

I have problems with sentences that contain expressions of future hope or prediction as they eventually become out of date. Sooner or later, the time specified as being in the future will become the past, rendering the sentence anachronistic. I'm not sure how this can best be avoided, but think that some guidance should be given in the rules to prevent this occurring. I have made this point here because of several instances in this article, but it is applicable throughout Wikipedia and i am not trying to criticize this author in particular. I hope he/she will understand that.

Examples: Peugeot plans to campaign the car in the 2009 Le Mans Series season, although it will not be capable of scoring championship points.

Vodafone McLaren Mercedes began testing of their KERS in September 2008 at the Jerez test track in preparation for the 2009 F1 season, ...

In November 2008 it was announced that Freescale Semiconductor would collaborate with McLaren Electronic Systems to further develop its KERS for McLaren's Formula One car from 2010 onwards.

3,000 × 3,223 pixels[edit]

The picture of the flywheel: What are 3,000 × 3,223 pixels good for, when the picture itself is unsharp, and also has nothing more (no details) to show in full resolution.It's like a gray wall in high resolution... no information in it, no further details can be revealed. This remark is valid for all type of images with this unnecessary resolution. (talk) 18:44, 10 June 2012 (UTC)

Feynman and KERS[edit]

The article claims that Feynman postulated the use of flywheels/kinetic energy storage devices. Firstly, flywheels existed long before Feynman. Secondly, the citation given links to an article discussing miniaturisation and nanotechnology, which doesn't mention anything to do with KERS. As far as I know, Feynman did not come up with this content, so can this claim please be clarified, and a supporting citation supplied. — Preceding unsigned comment added by JimmySinclair (talkcontribs) 01:47, 25 October 2012 (UTC)

Agreed; I removed the reference to Feynman.Wasoxygen (talk) 19:45, 18 April 2013 (UTC)

Any impact on turning?[edit]

I don't see any mention on how a rapidly spinning mass might affect a vehicles ability to turn. Is this an issue? If so, how have they managed to deal with this?--Hooperbloob (talk) 17:15, 22 July 2013 (UTC)

KERS working diagram[edit]

Added a Working Diagram for KERS. I created a new section after the one about FIA since this diagram shows the process in a F1 car (maybe it should be in the same paragraph?). The gif should start automatically, otherwise I think it shouldn't be this big. --TychoDodo (talk) 15:19, 1 December 2014 (UTC)

Peugeot 908HY[edit]

Was displayed at Le Mans 2011, tested by the works race team, but never raced. Certainly not at Silverstone and definitely not in 2008. — Preceding unsigned comment added by (talk) 19:19, 29 June 2015 (UTC)
