ramjet 1,089 Posted April 19, 2015 Report Share Posted April 19, 2015 Can someone explain to me, with so many mechanics looking after these cars between races, why do so many things seem to occur? If your daily driver did this sort of thing, you'd be wild and they are only serviced every 10~15k kms. I don't believe it is the complexity as these cars are pulled apart and put together all the time.

Advantage 910 Posted April 20, 2015 Report Share Posted April 20, 2015 800-900 bhp from a 1.6 turbocharged, hybrid powerplant takes some maintenance and is on the very cutting edge of known technology, but with strict rules on the amount of testing permitted. Stuff goes wrong. And that's solely considering the bits that make the car go and doesn't account for making the car stop or go round corners. Quote Link to post Share on other sites
ramjet 1,089 Posted April 20, 2015 Report Share Posted April 20, 2015 It wasn't the engines that I was talking about. It is systems like the engine just dying. There are motorbikes on the road which will rev to that rpm as well and they don't break down often? When you say testing, are they not even allowed to start and test?

redshift 32 Posted April 20, 2015 Report Share Posted April 20, 2015 There is a whole new level of electronc systems attached to the engines not just for the hybrid power generation. They also intereact with regenerative braking, brake by wire, electronic diffs etc. The big difficulty is that the engine/hybrid/systems package is now installed in a very compact body where it will be subject to immense temperatures, vibration and shock loads, humidty and the occasional rain/sand blasting. I don't for one moment imagine that they have had enough testing to cover every single combination of environmental extremes. We do electronics that is designed for 2G accelerations at low rpm, +70°, rain and humidity and even that is an eye-opener. I'm amazed that it works at all under 6G accelerations at very high rpm and a couple of hundred °C..... Quote Link to post Share on other sites
