Why shouldn't she? It's a neat little car.


But...She can't drive.


So it was me who flipped their Solstice on the Tail of the Dragon.

One correction to the reported incident - it was not raining at the time of the wreck - although I did get drenched by a brief thunderstorm as I waited for the wrecker to come and haul away my car.

As far as a description of the incident, I was coming up on a left hand curve on the Dragon and took the curve too wide. My right tires went off the pavement into the gravel along the side of the road. Unfortunately, I was unable to get my wheels back onto the road, and the car headed down into a slight ditch and up a sharp incline, which rolled the car over.

When the car came to rest, I was conscious and generally uninjured, but my left forearm was pinned between the top of the headrest and the ground. Luckily for me, a fellow Solstice owner was driving along behind me, and several motortcylists also stopped to help out. After a few moments of panic where I tried to dig the dirt out from around my trapped arm, a group of volunteer helpers gathered around to lift the side of the car up enough so that I could pull my arm out. Once I was unstuck, I was able to crawl free through the passenger door, which my rescuers were able to pull open.

I am amazingly uninjured, other than a little swelling and tenderness in the arm that was pinned. But no broken bones, head trauma, etc. Hardly even any scratches or bruises. My Baby was sacrificied, but gave its life to keep me safe. These cars are just amazing in how well they are designed to save us from injury.

Pictures probably give a better idea of the terrain, so here are a few for those who can handle it...

This is how the car ended up:

I doubt she'll be as fortunate next time. Hopefully she stops going to this sort of event.

She's in the Sostice Forum calendar. I bet she was posing on the car for some pictures, crushed the windshield, then decided to set the car upside down at the gap after beating it up a little more so, out of shame, she could claim to have rolled it. :)

The Pontiac Solstice and Saturn Sky are both RWD with 4-wheel independent suspension.

As far as Cadillacs, I believe the CTS and STS are both RWD with 4-wheel independent suspension.

Interesting. GM is making the same marketing mistake Ford did with the late 80's TBird/ Lincoln Mark 8.Those where both V8 RWD-IRS and no one knew about it. These were the finest riding vehicles on the road for the money and they stopped production of both due to dismal sales. As I recall the introduction of that chassis occurred along with their aquistion of Jaguar, long known for its IRS technology.

The Ford Explorer has been IRS for about 6 years now, and they redesigned the Expedition to use a similar platform about 2 years ago. They both handle unimproved, rutted roads like big cats yet the feature is not marketed.

Two roadsters, the Pontiac Solstice and Saturn Sky, will be rear-wheel drive entries. Other rear-wheel drive GM cars include the Cadillac CTS and STS sedans, the Chevrolet Corvette and the Pontiac GTO. Source (http://www.detnews.com/2005/autosinsider/0503/21/A01-123402.htm).

I'm pretty sure Car guys/gals are aware of GM's IRS cars. I didn't know anyone who knows what IRS is who wasn't aware of a shift back to rwd platforms by major manufacturers.

:)
People in SUVs like IRS because it rides better. People in Trucks like Solid rear axles because they're stronger (no CV joints to snap, etc).

People in Sports cars prefer IRS because it typically handles better. People in Muscle Cars like solid rear axles for the same reason as truck guys (also, IRS has more of a tendency to wheel-hop under power, IIRC).

Felt like I was riding in a car with mattress springs for suspension - HUGE amounts of body-roll, Vague braking, and numb steering. I'd never call it a "sports car".

I searched Clay's source and found no mention of the works "independent" or "suspension", although there is plenty of mention of "rear wheel drive" and 'did not sell enough to justify'. This confirms my analysis that GM has failed to market the IRS cars properly, as Ford did.

US car manufacturers build fine products, but flunk out in marketing.

No - it only means the Car was too heavy and ugly for people to buy. (shrug)

The GTO had near corvette levels of straight-line performance in a bathtub, non-exciting body. That was the real problem. IRS is so common nowadays I hardly think of it as a selling point - it's what is to be expected in a performance (other than straight-line performance) car.

I dunno about the weight issue so I won't comment on that, but ugly is a marketing failure, is it not? Several posters here commented positively on the OP car's looks, so it could be said that it is you who have not been marketed correctly.

IRS is only common on higher end vehicles, such as Volvo on up. Most lower priced cars marketed as "sporty" as simply FWD with trailer rear ends. So for a car in an reasonable price range to have RWD-IRS it is indeed someting to be flaunted.

No, Ugly is a design failure - NOT a marketing failure. You were stating GM failed to market IRS correctly. I'm saying IRS isn't unique enough for ppl to get past the car's looks.

I believe Volvo has no RWD cars. The ONLY volvos with IRS would be their Car-platform-based SUVs, or AWD cars.

Car guys aren't typically into FWD cars (which ALL have IFS -Independent FRONT Suspension, fwiw), save the Mini, and to some extent the 'tuner' variants of other pocket-rockets (Mazdaspeed3, Cobalt SS, etc). Frankly, IRS is the NORM for RWD cars nowadays - especially sports cars (Maybe we can thank the Miata for that, starting in 1989?) In fact, other than the Mustang, I can't think of another current RWD car with a solid axle.

Some people say they're bland to look at, but I think they have a minimalist/sleeper appeal to them.

I will agree that they don't attract attention like a 'vette does. Or a rex :)

Perhaps instead of sports car we should call it a "power car."

I think it fits the definition of Muscle Car; no need to invent new classifications. :) Unfortunately, many of the people interested in a muscle car seem to prefer a solid axle, ride quality be damned. Those interested in a car that handles well go for the IRS.

As far as IRS only being common on higher-end cars, I'd have to disagree. Most RWD cars anymore have IRS. You just don't find a whole lot of inexpensive cars with RWD - most are FWD econoboxes. The least expensive of the RWD cars, as far as I know, are the little roadsters (Miata, Solstice, Sky), and they all have IRS.

2. Unless things have changed Volvo has no FWD cars. It's been a while since I looked at Volvos so it is possible that I am wrong. But I doubt it. Saab, the other Swedish manufacturer, is all FWD.
3. All FWD cars have IFS. It's not necessary to specify "FWD-IFS". Any car guy would cuff you off the side of the head for that.

I think muscle car lovers would jump at the chance for IRS in an affordable package. The only way to get one is with a Mustang fitted with a Motorsports conversion. Large dollars and large weight penalty.

The last time I read about that was in Hot Rod magazine years back when they still had the FOX chassis, and before they began to go retro in '97. Remember that boxy body they had for over 10 years? As I recall the IRS was a bolt-on subframe, added a bit of weight and did not improve skid-pan performance at all. But they still claim it rode better, and I suspect that it did, especially on bumpy turns.

Muscle Car lovers believe, at least from what I've read and heard from a few friends that are muscle car lovers, is a solid axle is the only way to make a true muscle car. Some of these people are huge fans of the Camaro, and have flat-out refused to buy one if it comes with IRS.

You seem to be talking about the Pontiac Solstice that was rolled, whereas Darin seems to be talking about the looks of the Pontiac GTO being bland.

5. Perhaps you misunderstood. Most kids do drive ricers, all FWD, except for the ones with rich daddies, who drive beemers, all RWD-IRS.

Not All fwd cars are ricers...and beemers are motorcycles. Bimmers are cars.
Not every bimmer is rwd. ;)



6. That was the purpose of my question, post 15. But those are all under powered cars, are they not?

The purpose was to name inexpensive rwd cars? By asking if the solstice was rwd?

None of the cars I listed in that response are under-powered - all are sporty. In fact, the argument could be make the MX5 and Solstice/Sky twins are the only true sports cars listed. The Mustang and GTO are 'muscle cars', the RX8? No idea - probably closer to sports car than anything else.

I find that hard to believe. It must have been something to do with capacity. I'm sure if they offered an IRS with the same capabilities as the 8.8" pumpkin everyone would be gism-happy.

It's your choice to believe it or not - I was 'into cars' when the Cobra debuted with IRS and teh REAL mustang guys went ape-shit.



If you drive it off a cliff you'll get at least 1g out of it- for a short while, anyway.
I don't see any other way of getting any real speed out of it though.

He and I drive the same make/model of car. I've had my car's speedometer up to 184mph...(shrug) What do you consider 'real speed'? Timed acceleration in the 1/4 mile? Top Speed? I haven't measured - but I know my car has seen WELL Over 1 G :) (laterally)

The solstice GXP would give a Mustang GT a good run for it's money in a straight line. The GTO would SMOKE a mustang in a straight line (As it had up to 150 MORE HP). The Miata is powered 'just about right' - while it (nor the rx8) would win many drag races, they are 'momentum' cars; where the driver is rewarded for fighting the urge to use the brakes. :)

FWIW, I'm not sure what you drive, but if it's a car with less than 300 hp, and you come across a Little Wagon which reads Mazdaspeed3 on the back...don't try to race him. Even being a FWD, he'd probably smoke ya! ;)

Car guys aren't typically into FWD cars (which ALL have IFS -Independent FRONT Suspension, fwiw), save the Mini, and to some extent the 'tuner' variants of other pocket-rockets (Mazdaspeed3, Cobalt SS, etc). Frankly, IRS is the NORM for RWD cars nowadays - especially sports cars (Maybe we can thank the Miata for that, starting in 1989?) In fact, other than the Mustang, I can't think of another current RWD car with a solid axle.

Turbos create MOUNTAINS of torque. It's one reason they are popular in the diesel truck platform. Well-designed turbo systems produce VERY VERY limited amounts of 'lag' or 'boost threshold' - See the new BMW 335i for an example.

What did you do to dial-in your TBird?

Doing a bit of googling, I've found a Car and Driver showing .89 for the '05 Mustang GT. Keep in mind, going from .89 to .9 could be as difficult as a complete tire/wheel swap, OR as easy taking the car to a different test facility. :)


I wouldn't have believed it - but I found a Mustang Shelby GT showing .92(!!!) on a skidpad. That's the same as a 2007 RX8! (Makes me wonder if my particular RX8 would generate 1G? .95 at least, I'd bet, on a skidpad. I'm very sure I've seen MORE than 1G on some of the corners on one of the tracks I've ran) WOW! Thank GOD for WIDE, sticky TIRES on that mustang - it surely wasn't the suspension doing the work, hence the comment from one reviewer in the test:


The live axle, on the other hand, is responsible for the worst handling of the group. In truth, the blame isn’t all located at the rear. The front suspension is lousy enough that one tester compared the whole package to a 20-year-old pickup truck. On a particularly rough stretch of road, the vibrations were severe enough that the hood clips worked themselves loose. Combine that with the greatest curb weight and its overboosted, numb steering, and it’s easy to see why the Mustang was the last choice on the curvy roads surrounding Lake Mead.

Interestingly enough - In this same review (Pitting the Mustang Shelby GT vs. The Nissan 350z, Audi TT 2.0T, and the RX8), the RX8 WON - these comments summarize why:


Get off the highway, and the annoyance caused by the wheezy engine subsides as cornering speeds increase. The suspension takes hits from the road like a champion prizefighter, so much so that during our driving loop the RX-8 was actually the fastest car on real-world roads.

...But just as on the street, the RX-8 inspires confidence in the driver to carry more speed through the corners, and the challenge of maintaining velocity in this car is ultimately more rewarding than relying on the gas pedal in the others to make up for your mistakes.

It all depends on how you want to drive. In the practical world, gas-turbos just don't have the low-end torque needed for most situations. Now if you want to rev the car up while holding the brakes and wait for a light tree, then that's your thing.

"Fun" is a dependent on the observer, is it not? When I was into it, fun was out-handling the so-called "great handling" ricers, climbing hills faster than expensives Saabs or BMWs, all in my grocery-getter '85 Tbird.

Tuning for that car, BTW, started by ordering it right from the factory. It took a little research to find out that the avalialble trailer towing option was actually the handling suspension from the same chassis Mustang. This included much larger anti-sway bars, polyurethance bushings, stiffer springs and quad-shock rear end. Tuning also included replacing the power steering valve spring with a slightly harder one from the local harware store for about 10 cents, turning the one-finger variable ratio power steering to one that you could actually feel the road. I also use to do my own front end alignments with an oak block, string, tape measure and carpenters level, and set up the camber to up to +3, toe to zero. Also locate junk parts for shock tower connectors. And never forget the chalk test for tire inflation.

Well - THREE degrees negative camber is a LOT - you probably wore through the insides of your tires VERY quickly. What size tires?

At the prison I worked at, we had two, gigantic, V-16 Detroit diesels with quad turbos blowing into duel supercharges. Even with a massive exhaust system, it was deafening in the generator room when they were running. They'd generate enough electricity to not only power the prison, but half the town of Boscobel as well. The most awesome engines I've ever seen. No, I've never seen the diesel in a locomotive or a ship.

[1] Sure there is. It's called a Supercharger. But as I've illustrated, a well-designed turbo system can offer up MOUNTAINS of torque down low. :)

[2]How could I? I don't know him. And even if I did, I'd have no idea how good of a driver he is. Driving against a 'worse' driver doesn't make somebody a 'good' driver ;) :D

[3]Honestly, even a Stock New mustang would be able to 'out-handle' that TBird you had, on probably ANY course. Get into a Stock Miata, or RX8, or Lotus, or C5+ Corvette? Wet-Dream-inducing. :)

[4]Well - THREE degrees negative camber is a LOT - you probably wore through the insides of your tires VERY quickly. What size tires?

[5]I run -1 front and -1.5 rear, and about 1/16th (IIRC) toe out, front and rear, on 245/40/18s. So far, they're holding up well - after about 6K miles, I'm about 1/3rd done with fairly even wear - but I'm hard on tires. .

:D

1. Good point, but one that brings up another: a supercharger is not a turbocharger. Since it’s mechanically connected to the crankshaft, its “on” all the time, hence no lag. That’s the same reason why a diesel turbo works well, as diesels have a large exhaust flow at idle speeds.
2. I was being facetious of course, but he thought he was hot. And there were many others who learned that they were not, I assure you.
3. Back in those days the Mustang and the Tbird shared the same chassis; the bird was just a few inches longer. So the stock Mustang would not out-handle a tweaked TBird. With regards to the contemporary Mazdas (owned by Ford, BTW), I would hope that something was learned in 22 years by the engineers, as they were at best mediocre back in 1985. And the exotics? You flatter me with the comparison, but I assure you it is undeserved.
4. 3 degrees was huge, which is why used that set up very sparingly. As I recall I ran 55 or 60 series (can’t remember) 235 width. I remember running air pressure around 42 psi or so. They were 15” rims, as 16’s were just becoming available and the set up was much more expensive. As with wear? If you have the proper set up for the driving being done, which in this case was a closed course, the wear should be even, which it was.
5. As I never tweaked an IRS I couldn’t tell you if the 1.5 is high or not. I suppose it has a lot to do with F to R weight displacement. I remember working with some VW Golf drivers back then. They’d routinely take turns on with the inside rear tire off the ground since they had such poor weight distribution. So I suppose the more balance the car, the closer F&R should be equal. Also a more tourquey engine would warrant less rear camber, as the acceleration through a turn would tend to shift weight rearward.

Actually - the technical name for a supercharger, way back when, is a "super turbocharger". Centrifugal superchargers make max boost, generally, at max engine RPM. Therefore, a Properly sized Turbo can Seriously out-perform it because it can go from 0 to Max psi within a few hundred RPM. Thus, one is making, say, 10psi from 3000rpm to 8000, vs a Centrifugal SC where one makes 'parts' of 10 throughout the powerband, to end at 10. That's one example of where a SC might 'feel' laggy. Or another may be if it's not properly sized for the engine - some engines may lose MASSIVE amounts of torque simply spinning a blower. Diesels are turbos, typically, for 'more' than just the exhaust flow reason. Frankly, there is a myriad of reasons why one would choose a Turbo over a supercharger.

Also - a number of companies run their SC's with check valves, or clutched pulleys to allow it to 'free spin' when not under heavy throttle. :)


3. Back in those days the Mustang and the Tbird shared the same chassis; the bird was just a few inches longer. So the stock Mustang would not out-handle a tweaked TBird.

"New" Mustangs. With the advancement in even old-skewl technology, a 'new' OEM mustang would likely out-handle even Upgraded mustangs of yore.

Not really 'owned' by Ford - Ford does have controlling interest, though. If you'd wanna go back 22 years - find a 1985 RX7...Good times. :)

I'm saying if you thought that TBird handled well, a newer car (Even a new Mustang, but specifically a new sports car) might blow your mind - turbo or not :)



5. So I suppose the more balance the car, the closer F&R should be equal. Also a more tourquey engine would warrant less rear camber, as the acceleration through a turn would tend to shift weight rearward.

...which is why you'd want MORE contact patch there (setting camber closer to 0 degrees.) My even low-torque RX8 shifts weight VERY nicely, thanks to it's 50/50 balance and low polar movement of inertia.

What are you guys measuring camber with? I used a hardwood block cut smooth along its long sides on a table saw, and the length trimmed to the inside diameter of the aluminum wheel. Make sure the car is set on a flat floor, or at least both tires at the exact same elevation. Use various thicknesses of plywood under one wheel if necessary. Hold the block against the rim vertically and use a carpenters level to get a plumb line. Measure the gap dimension between the block and the plumb line with a vernier or dial caliper. The tangent of the gap/ block length is the camber angle.

You can measure toe as well but its not nearly as easy. First make sure the steering wheel is dead center. Then have a buddy hold your special wood block to the front wheel horizontally. Tie a 20’ length of fish line to the front of the block, squat next to the rear tire and pull the line tight and parallel to the floor. Slowly move the string towards the rear wheel, until the line makes contact with the rear of the block. Then measure the distance between the inside of the line and the rear wheel rim. You then have to do a little math, taking into account the relative tracks (widths) of the F&R, the length between the center of the front wheel and the point on the rear that you measured from, etc., then use trigonometry as with camber.

I watched it twice the first time. To me it looked like he reved it up to get boost, and when he engaged the cltch the engine was not producing enough tourque, and he almost stalled out. Now that was a static situation. Try shooting out of a turn with the same car, and add the variable of traffic.

I'd rather drive a car with a more predictable power band.

You might be right about engine development. However, I'm speaking about turbocharger development. ;)

Those dyno runs are done under load, in 4th gear, from low-ish RPM. Any lag would show, if it existed.

A turbocharger won't produce boost unless it's under load. Therefore, if that Porsche is a manual, he wasn't revving to produce boost. If it is an auto, he wasn't engaging a clutch. ;)

If you're driving your car correctly, you stay above the boost threshold while doing just about anything other than putting around a parking lot.

If I understand you correctly, you like the feel of a large, naturally aspirated engine. That's why you like superchargers. A supercharged engine builds power progressively, like a larger naturally aspirated engine.

What you prefer has absolutely nothing to do with low end torque.

FWIW, you can allow a turbocharger to build maximum boost as early as possible and get heaps of low end torque - OR - you can add a TPS based boost control system and make the boost come on progressively, just like a supercharged or large naturally aspirated engine.

One very nice thing about a TC system - One could choose to stay out of boost all day - even driving up to freeway speeds, if they wanted. :)

:D In PGT, I could get up to about 65-70mph with light throttle before boost would build. That helped the car get actually BETTER fuel economy than prior to the TC installation, if desired. My Before Boost best mpg was about 25mpg. After? I got 28mpg on a road trip...by driving nice.

Mr. Porsche appeared to be a manual. In order to load the turbo he would have to have front brakes applied, applying clutch pressure, and hitting the gas. I guess that's the way turbo dragsters do it, anyway. But that's not too practical for launching yourself out of a turn in traffic, as I stated earlier.

Perhaps with some computer tech a manufacturer could reduce or elimate lag, and if that's the case Mr. Porsche needs to do his homework.

The last time I worked on a dyno was about a year ago at a Harley shop. The load is imposed by a truck brake. The vehicle turns the dyno at a certain RPM, and the brake is applied with feedback to the vehicle trottle until max load at the rpm is found, then a new RPM is selected and the process repeats throughout the RPM range. I don't see how that process could detect lag, but perhaps you could enligten me. ;)

What that shows is a transition in the tourque curve at around 5500 RPM. If its a turbo engine the boost doesn't start until then. You could have the engine spinning at 7500 with no load, like Porsche did on the line, and the turbo would still not be making power.

1. But the dyno SHOWS the 'lag'. The turbo begins spinning as soon as exhaust passes through it...it 'lags' until enough exhaust causes it to spin fast enough to produce usable boost.

2. But I've shown you dyno evidence of "no" or "so-small-as-to-be-no-Lag."

Here's just ONE example of a modern turbo system:


BMW’s first U.S.-market gasoline turbo, a 3.0-liter blown six-cylinder, has two small IHI turbochargers that each pressurize three cylinders with a maximum of about nine psi of boost. Direct fuel injection, a first for a BMW gasoline turbo engine, helps to cool the intake charge and allows a high 10.5:1 compression ratio. The block is made from aluminum, not magnesium and aluminum as used in BMW’s naturally aspirated straight-sixes. Horsepower is 300 at 5600 rpm, and the peak torque of 300 pound-feet arrives at just 1400 rpm and hangs on until 5000 revs. We’ve driven the 335i, and if there’s any turbo lag, it’s infinitesimal.

One more


...considering the boost pressures (15.6 psi at its peak), the revs come surprisingly lump-free. Mega-boost cars often have mega-abrupt transitions from boost off to boost on. (The Mazdaspeed 6 has a) steady, deliberate surge rather than a sudden whoosh

The dyno can't show the lag as explained earlier; dynamic throttle position is not reported. The report about "infinitesimal" lag is a better indication. I am aware the BMW held off using turbos for a long time because of the lag issue. Apparently they did a nice job and should consult for Porshe.

Of course it can show lag; I've shown you how. Are you saying you want to know how the turbo performs under every possible throttle position, by gear?

Sometimes I think you're just making up stuff for the sake of being difficult.

Porsche's turbo systems have even 'less.' Read up on cars today, Glock, and things such as DFI engines and Variable Vane turbos.

I'm not being difficult; I'm simply being scientific. You insist that a chart shows something that it doesn't.

You don't understand boost threshold vs. turbo lag.

The guy starts out in 4th or 5th gear...floors it...and waits for the exhaust to generate enough velocity and heat to get the turbo making boost. This happens VERY quickly - which shows the turbo does NOT take a lot to spool up. It's 'not laggy'. The dyno clearly shows that.

How can a chart without a time axis show lag (which is a function of time)?

RPMS. Look at how quickly the car builds power as rpms increase. That shows lag, or lack thereof.

No the chart shows RPM vs. Torque. It does not show how that torque builds with time from an input at the gas pedal.

I think you're just trying to be difficult.

I think you've clearly shown that you don't know WTF you're talking about. ;)

The dyno you describe isn't typical of the type that are used on automobiles. A DynoJet, for instance, applies a load as the vehicle comes up to speed. Usually this is done in 4th gear (1:1). It's a continuous measurement.

Go drive a few modern turbocharged vehicles and then get back to us. If you'd like a list of said vehicles, feel free to ask.

www.google.com Wikipedia.org works too. Bring your level of knowledge to 'within the past 20 years'; that'd be a great starting point.

The chart shows Horsepower and Torque. Torque is measured and horsepower calculated from torque. One can see the WAY the engine makes power by looking at the chart. It's VERY simply stuff now Glock; but if you refuse to learn there's no point in going on beating myself up trying to teach you.
