Porsche 1 hour Crashed Unsure Why Can you help?

[ginge]

Hi

I had a Porsche Boxster 99 reg for a couple of days, yes a couple of days, I will explain in the best detail possible. I was driving, not at a significant speed as it was Bank Holiday and I was going into a seaside town so traffic was busy not heavy but moving about 40mph, the road conditions, well it was slightly wet but was not raining at the time , I was going completely round a roundabout to go back on myself (as I had missed the turn off), I accelerated as I was coming off the roundabout when suddenly the rear end shot out, I tried to correct this and couldn't the car spun across the road about 10ft, and hit a curb.
There was not a scratch on the actual car and the grass verge was only slightly damaged (I think where I was trying to get back off the grass).

I tried to drive the car but couldn't. A motorist pointed out my headlight had fallen out. I picked this up off the road and drove about 5 yards thinking all was ok, ( as it wasn't a bad accident). I could here vibrations so I pulled over onto the grass verge. I thought it was something under the car but it wasn't. When the recovery vehicle came he checked the car, as I said the paintwork wasn't scratched at all but the rear wheel drivers side was virtually hanging off.

This is the damage I have been advised is wrong my mate tells me there is no way I was not speeding due to the amount of damage, I can assure you I wasn't hence why I am after a bit of advice, how all this damage could possibly happen.

Are you ready?

Sub Frame Snapped,
Both driveshafts broken,
Rear Wheel Hub broken in two,
Radiator Bent,
Both wheels damaged driver side,
Headlight broken,
Both Wheel Arches Covers broken,

And a few other bits and pieces. Been told at the moment no reverse gear but this worked after I curbed the car as I had to reverse slightly for the recovery truck.

Any advice would be appreciated.

I'm not clear on what advice you're looking for.

If you're wondering how you could have caused that much damage from a simple spin out, it's quite possible. You don't say how fast you were going at the time of the spin, but even a "slow" 15mph would be enough to do that much damage. Porsches were not designed to stop sideways into curbs using the wheels as the stopping mechanism.

There are plenty of threads here about people who lost their Boxsters on wet or damp roads. It happens. With the amount of damage you've listed, you may have totaled your car. You may want to look into a 987 with PSM - Porsche Stability Mgnt, which is a computer system to assist when things get going sideways. It's also known as Please Save Me!

Good luck with your situation.

I would envisage about 15mph, I understand Porsches aren't designed to go sideways, just wandering how on earth, I could total the car only driving slow. Thanks for the advice though, truly appreciated, at least in my head now I know this can happen. TBH I posted as my mate, whom I had the car on test drive from blatantly thinks I was speeding and I know I wasn't.

What kind of shape are your rear tires in? Good tread or not? Sort of irrelevant at this point I guess, but I just wonder if wet road + balding tires + accelerating in a turn all conspired to do you in. Sorry for your predicament---with that damage in a '99, it would seem dangerously close to totaled. Have you gotten estimates?

£3k up to now, so I think it is totalled. I don't think anything was wrong with the tread.

Just a guess, but from your list of broken items, I notice that you state that both drive shafts are broken. Not sure if it is possible to break both drive shafts from only getting hit on one side, so I theorize that a drive shaft may have broken as you were exiting the roundabout and that is what caused you to slide into the curb.

I have to be honest and say I do not know much about cars, especially Porsches do they have more than one driveshaft (I know I have listed this but I have listed what the garage has said). How common is it for a drive shaft to break, bearing in mind the Porsche was 12 years old? I would also like to Thank you for your response.

I believe that your mechanic is referring to the axle shafts on your car as the tranny is a one piece trans-axle. The drive between the differential and transmission that we normally think of as a drive shaft is inside the transmission case.

Boxsters are built to be light weight and handle curves. The are not that stout in terms of durability. I have learned this the hard way as well. I bottomed my car out on an unfamiliar back road. It did not feel that bad, but when I went to shift, I realized something was not right. In my case both lower tranny mount bosses cracked. The tranny came to rest on top of the rear sub frame. Porcshe in it's infinite wisdom cast the bosses into the case, and do not make that part of the case available so the only option is to install a new/used tranny. The impact also destroyed all 4 CV boots. So I here ya, I had my Box for all of 2 months when it happened. The only good thing is that it forced my hand on the IMS as it did not make sense not to do it when the tranny was being replace. Keep in mind that my Tranny was never impacted, it was strictly inertia that did the damage.

What you did was a blunt impact to the car in an area and from an angle in which it was not designed to take a blow. I am not surprised at all that it suffered the damage you mentioned.

Light weight, rear drive cars should be driven with care in anything but bone dry conditions. A quick light rain will make the roads very slick because it's just enough to release some oil from the surface of the pavement but not enought to wash it away. Be careful out there!

this is probably the most painful part. took the car on a test drive and possibly totaled it. hopefully your friend is a good one...

I probably have most of those parts from my used 2001 S or 2000 Base that I am parting out.

No idea how much to ship to UK from Texas -- but otherwise I can save you a bundle.

email me at mike@lonestarrpm.com if you are interested.

This thread seems a tad suspicious to me. A word of caution if any transactions are about to take place involving money, parts etc.

I hope I am wrong.

I did something simliar 3 years ago - wanted a boxster forever, took one for a drive on a foggy damp December day. Spun it leaving a roundabout, mounted the grassy kerb and hit a lamppost side on. Mostly front 1/4 damge to wing, raditor etc. £3k damage and I bought the car as I had bent it. Sold it straight away, but it was an expensive test drive.

I learnt 2 things, the power of the boxster needs to be understood in bad road conditions to prevent the back end coming round, alway check insurance state when test driving. Oh and make sure spouse is rewarded for not complaining too much about the cost that we had nothing to show for.

[Perfectlap]

so who is paying? and how much?

[Perfectlap]

Don't know if the OP has had driving instruction, but I spun my Boxster a few months after buying it and I had several seasons of autocross under my belt at the time. Luckily because i knew which way to turn the wheel when the back end gets jumpy I avoided a wreck with a parked car that was inches away. Yep...it was wet out.

When you transition from slow to faster while turning the wheel on wet ground...you better be used to quick flicks of the wheel and good with quick reactions. I was really stunned at how quickly the car did a full 180. The car is neutral but isn't loyal about it.

I lost the rear end of a non-PSM '97 Boxster going quite slowly in a hairpin in Tasmania. It's certainly easy enough to do if the road is slick (which this one was) and if you apply the power a bit earlier than you should have (which I did). Fortunately I was going slowly enough to not slide into the retaining wall as it was a rental car and had a rather exciting insurance excess.

The mid-engine Box has a lower moment of inertia than a front or rear engine car. The car is more likely to spin. Just as when figure skaters spinning pull their arms and legs in closer to their bodies, there is a remarkable increase in spin. No gettin around it.

Someone correct me if I'm wrong, but I'm not sure this is true? My understanding (and, to some extent, my experience) is that, with the mid-engine design it's actually less likely to spin...BUT once she goes the figure skater phenomenon kicks in---the car then spins with reckless (and hopefully for the driver, "wreckless") abandon!

A mid engine car is more neutral and is somewhat less likely to "oversteer" than a rear engined car. However, when the word "spin" is mentioned that is what is really meant...as in like a top. I mid-engined car will spin unlike any other car because the CG is in the center.

[jacabean]

it does not take much to spin a boxster in the wet . PSM is a great system for those conditions . The damage he got is what you would get in any other car . no car can handle side impacts to the suspension and drive components .
