No upsets here -- although I spilt some coffee on my keyboard a few days ago. I remember a small British sedan that had little chrome arms that were just behind the doors -- with a reflector --- a good simple solution.

If an American V8 was good enough for Rover -- it can't have been engineered too badly -- could it? The same engine block was used in F1-- so it can't have been that bad a piece of casting.

OK, fair point, any block that makes its way into F1 is pretty good.

Mind you the mention of the word Rover associated with it immediattly demines it.
Was that not the infamouse engine which you had to refit the steel dowels holding the cylinder head on every time you changed the head, which, being a Rover, was quite often?

Tom I don't know about that problem of replacing the steel dowels or if it was that motor. Anytime I would do a headjob and send out the head to be milled flat-- I would replace the head studs on any motor I was working on. Were those steel dowels locating pins or head studs? Did the motor need head gaskets replaced constantly? That would be intolerable. We both just like interesting engineering --- I was looking at a few pictures of the 250cc Honda 6 cylinder yesterday -- incredible -- I'm not very good with the links and internet --- but if you go to:
http://www.eurospares.com/graphics

Its a list of graphic picture files. Dial down to honda6-1.jpg and take a look. It's the 4 valve cylinder head from that motor. I think we both will be in agreement --- it's marvellous.
Edit: it's 2.jpg of the Honda6 series
Edit 2: If anyone has pictures of the internals of Honda's GP 125cc 5 cylinder I would certainly like to see them -- Thank You

Tom, you must not have read my post correctly. I said nothing about top speed. I said it was the fastest car 0 to 60. The benchmark of every performance cars acceleration. Besides that, it's top speed is about 240. So I guess that's pretty fast in anyones book. Certainly mine. It pulls 1.01g on the skidpad, does 240mph, less that 2 seconds to 60mph, and less than 5 seconds to 100mph. So it's a very fast car. http://www.z06-corvette.com/super/linge ... tt-427.htm

Also you must not know anything about Jeeps back in the 40's. Pulled us through WWII beautifully, was da*n near unkillable (is that a word?), and many men thought of it as their horse and were sad to see it go if it ever broke down. Which was very rare.

Another thing Tom. If auto transmissions are so bad, and you are lazy for using them, then why did F1 use them a couple years back. If they are so bad you'd think they wouldn't use them right?

A/C may not be useful in Europe, but I know you have it in homes and it's very nice to have. So why is it not useful in a car?

Ciro, why the quotes on the 7 liter regular engine. Is it bad that it's regular, or would it be better to have troublesome dual overhead cams? What difference does it make how the engine is designed if it gets the job done. Not to mention it does it's job beautifully with the simplest and easiest design possible? Why is it that American cars are considered inferior if they aren't complex? If you can do it cheaply, simply and it works great, what is so bad about that? It seems snobby to me to think otherwise.

As for suspension, if leaf springs get the job done, why beat yourself over the head trying to make independant suspension work on the rear. If it works, again, who cares? I could care less what it has under the rear to plant the tires. If it ain't broke, don't fix it. Refinement and fancy designs are for people who can't tune. If you can't do the basics, no amount of fanciness is going to make you or it any better. Leaf springs are not a bad design, they take some tuning to get right, but when they are they are devestatingly fast. You don't need all fancy schmancy suspension to go fast or ride nice.

Ciro, a NASCAR pit stop is ballet at it's finest. F1 guys should be embarrassed those guys can do three times the work and take only about 5 seconds longer. They use a third the people, have five lug nuts to take off and put on, two guys on each tire, do one side at a time, gravity feed 22 gallons of fuel in two seperate gas cans, and they do it all in 14 seconds. A fast process in anyones book. Compared to 21 guys, 10 liters of fuel PUMPED into the tank, ONE lug nut to remove and replace, and doing all four tires at a time, they are MUCH quicker.

I'm closer to US than Italy. I still prefer Ferrari. I'm not too religious though, so it has nothing to do with Christ.

Your average guy can't work on a Ferrari, even the ones who can afford them. They are beautiful cars, but I doubt they'd run 100,000 miles without having to go back to Italy for some sort of major work.
You can have your doubts and I don't care to argue them. However there are Ferraris beyond 200,000 miles without going back to Italy for major job. Please don't comment on things you don't know. Some may have false ideas about US cars, but you just proved that US people also have false ideas about EU cars. ;)

According to your story link, the Ferrari is over twice as much and only a second faster or so.
"Z06 costs more than half a F430 or Gallardo, 90k vs 150-160k "

The numbers are quite different over here, but the ratio seems about same. Ferrari is some +50% more, not twice as much. I'm sure the relation can be very different somewhere else.

In a car you can't fix yourself.
Be honest. Do you really think that's an issue for potential customer? I bet most couldn't fix the simplest basic car and even if they could, very few probably would get their hands dirty.

Because you guys are jerks, that's why.
Well thank you very much. Have a nice day sir.

Ray, your love of that damn vette verges on an obsession. Frankly acceleration figures are pish, they mean nothing because the average driver couldn't get 0-60 in 8 seconds without breaking traction whatever the car. Its all very easy quoting figures but you have to bear in mind that it was probably a computer that reached that time and if not it was a guy who'd practised for so long and only pulled that time off once.

Auto transmissions were used in F1 because they were so much faster than a guy with a gearstick, they could change gear at exactly the right time faster than it takes you to blink, literally, of course they were going to use them. And besides, they had to prove F1 was the pinacle of technology. The Ats on your average car are no better than an alert driver and at the end of the dy are just another component that could go wrong.

There were far better vehicles available than the jeep for WW2, its just that the jeep was cheapest to make. They were quite 'killable' and the only reason they rarely broke down was because they were so simple. Saddly your jeep has spawned a huge range of hideous gas guzzling 4x4s which people are convinced they will need one day and when they regularely brake down people turn round and say' but they're supposed to be invinsable' hence my comment. You can keep em.

A/C, Ok it is useful on your side of the pond but its bloody freezing over here. The 2CV (my avatar) had a heating system designed before the second world war, it is astronomically efficient and never ever breaks down.

Carlos, I believe it is the locating pins that need replacing every time you change the bugger. Honestly i reakon you go through a head gasket at least once every 3 years on one of these monsters.

Lots of other examples too, like the M4 Sherman tank, P-51 Mustang, etc. The German counterparts were better engineered, but more complicated and expensive to manufacture and maintain.

Thanks for the Road & Track article. I wonder why they did not test the Golf HPA R32 (best bang for the buck?), the Viper 1100TT or the Mercedes GLK. They don't have so much sex-appeal but they seem nice cars to me.

I share Tom's and Ray point of view. My old Goat is funny when you wet the drum brakes. This thing weights like 120 imperial tonnes give or take a few (that's like 3 million grams, expressed in euros) and when the brakes are wet, I swear it has a system to increase the mass by 200%. It works wonders for your left foot braking! ;-)
The test was made by Quattroruote to compare on track the cars of the “Club of the 4 seconds”, referring to the 0-100km/h for “normal” production cars (not purposely tuned cars but the ones normally available). Then they probably picked 3 European and 3 American cars because they did it in collaboration with R&T so wanted to make something interesting for both. The questionable choice IMO is the 911Turbo instead of the GT3, it’s true that the latter loses a couple of tenths in acceleration so it’s a bit over 4”, but it’s the 911 of “normal” production more biased towards track performance so for that test would have made more sense.
As for the Viper, the only one available here is the SRT10 and costs about 115k € like the GT3.

Anyway don’t get me wrong, I actually don’t care much about the few tenths difference in laptimes or accelerations between these cars in the hands of experienced test drivers, even if I had the money to buy either of them certainly my choice wouldn’t be driven by that, I wouldn’t look for that kind of performance. I had a few trips on the track with cars powerful enough to understand that something also seconds slower is already more than you are ever going to need and that lot of practice is required to get even vaguely close to cornering potential of similar cars, let alone be able to find the difference at the limit between a Z06 and a F430. (For instance the car that gave me most fun on the track was a Fiat Barchetta, I didn’t get over 160-165 km/h, but without roof, helmet on, car floating and jumping over kerbs it was lot of fun. When I drove a 4S I was too worried about the risk to put it on the wall for having time to enjoy my driving turn)
It’s just that, if we really want to look at the data of absolute performance, let’s do it right, comparing apple with apple and orange with orange, so put similar performance tyres on both cars and you see that the money the F430 asks more actually mean something on the track too, even if that’s not the main reason someone decide to puts on the table for it enough money to have a small apartment. And I think it’s pretty clear from the article that also the American journalists notice it’s much more than speed. The F430 doesn’t cost almost twice the Z06 just because it’s a couple of seconds faster. At that level of performance even the slowest is fast enough anyway.
West wrote: Not knocking the Ferrari but where I live (southern California) everybody has a European car and everybody pretends they're rich or successful because of it.
Well, if they do it solely for that reason those are definitively snobs. But that doesn’t mean that your experience applies on this side of the ocean, here the European cars aren’t really that exotic ;-)
And you can bet I wasn’t trying to knock down the Z06 either, the only point I was trying to make was to explain the reasons the Z06 doesn’t have much success over here, it’s just that here isn’t as cheap as it’s in US, it costs basically same as a Porsche 911.
And given that money aren’t a factor most of people prefer to renounce to the performance advantage of the Z06 and pick the 911 or maybe even a Jaguar XKR or a BMW 6 Series or a Mercedes CLS, all are in that money range for both purchase (around 80-100k €) and daily driving (not few thousand € per year).
It’s not about being European snobs, jerks and idiots as your country fellow not very nicely suggested.
It’s just that for most of people those fits better with what they need from a road car for that kind of money, they are all different and focusing on different qualities obviously because the drivers are but mostly they cover the different requirements of European drivers better than the Z06 does.

Try to pay 6 $/gal for your fuel and to have annual expenditure for taxes and insurance related to engine displacement and maybe you’ll see it. And before you start with another post using insulting and blaspheme language, I’m not saying that you are an idiot for thinking that the American way is better, I’m just saying that here conditions are different from the one you live in and we have to adapt to our conditions.

BTW, I’m sure that if we met personally and I used to describe you or your country fellows the words you used to describe me and Europeans in general you wouldn’t have reacted well. So if you want to be respected treat other people with respect.
Ray wrote: Another thing Tom. If auto transmissions are so bad, and you are lazy for using them, then why did F1 use them a couple years back. If they are so bad you'd think they wouldn't use them right?
In fact they don’t use them.
The automatic Tom is referring to, the one you have in mind, is the real, mechanical, automatic gearbox with a torque converter instead of the clutch, heavy and not efficient invariably leading to car’s performance drop.
The gearbox used in F1 and in many race and road cars (like Ferrari F1) on the contrary is basically a manual gearbox, the difference being that clutch and the forks (or the drum that moves the forks in case of sequential) are operated via hydraulic or pneumatic actuators. While pulling the paddle the driver just sends a signal to the ECU that then, via actuators, ignition cut, throttle control etc etc, does exactly the same operations a driver would normally do with a manual gearbox, but it does them faster and consistently with more precision. At that point to leave the ECU select the gear ratio automatically is just a matter of software. Anyway even when automatic gear selection was allowed in F1 some drivers still preferred to not use it for downshifts, at least not in particular situations. Since few years this automatic selection is forbidden so it’s the driver that manually calls each gear change, upshift and downshift, but from the mechanical point of view the ban had no impact.

I must apologize. I've been upset for the past week or so because I was let go from my job because the company couldn't afford to keep me. So I've lost my job and can't, or haven't been able to, find any job to replace it. You'd think a 24 year ol guy with 5 years military experience would be able to find a decent job pretty quick, but it doesn't work that way. So I've been irritable and I took it out on you guys. So, may I ask your forgiveness? :oops:

I'm just tired of hearing how all American cars are dumbed down, lazy, shoddy engineering pieces of junk. They aren't at all, they are quite good cars, and some are very good on a world level of competition. And without getting into politics too far, the $6 a gallon for gas is your problem to fix. I can't control that and blasting a car for something that isn't it's fault is not exactly fair.

Reca, I know how an F1 trans works, I just think the same laziness applies. F1 cars are not designed around a driver, they are designed with all the electronic help in mind. I think it's lazy of the drivers to have an 'auto' trans. Takes away from the skill.

You are all still bashing the fundamentals of American cars. Automatic transmissions aren't a bad thing at all. They are there because people don't want a stick, not because they are lazy. A/C is a comfort thing, doesn't make it a bad or stupid design. Modern jeeps were not spawned by the Willys in WWII. They came when Chrysler bought the name. Yet again, disdain for something because it's simple. And they were great vehicles for thier design and were very influential in the outcome of the war. Good design and it accomplished what it was designed for, you don't need a fancy design for something in that area of operation.

If we are goin to debate the speed in all avenues of a car, 0-60 DOES in fact matter. What should we compare then, refinement? The type of headlight bulbs? A computer didn't get those times. The opposite is true, you directly control wheels spin on that car with the clutch. You can't even get anything other than a six speed manual in that car. So how is a computer going to make that time?

I'm just tired of hearing how crappy and 'simple', or not sophisticated American cars are from reviewers or critics. We don't bash Euro performance cars without a really good reason and most of our critics LOVE Euro cars. Which I give credit where it is due. I don't think there is a whole lot wrong with any Euro car. They are very good designs. The F430 is a great car. I just don't like the snobby attitude about American performance cars from the likes of Jeremy Clarkson and some of the guys on here who have bashed American designs. I haven't said Euro cars are junk.

We actually had a debate of F430 vs. Z06 a while ago; it ended that none of us drove or will ever own one of these cars, so there was really no point in debating which one is better.

It just pisses me off that there are a lot of spoiled kids in SoCal whose parents bought them a Euro car; those kids think they're the sh*t or something when they haven't even put a damn dime on the down payment. I personally know some people who just love to tell people they own BMWs and that they have to park it where everybody can see it. The worst part is that they lie about which model they own, just to impress people. Two of them own 325is, but they remove the badges so nobody can tell. One of them tells people it's a 330i.

Another story... I was drinking with a couple of people at my friend's engagement party. A girl kept calling me ghetto while proceeding to tell me she drives a 325i coupe. Big deal. Then it turns out she's 50 grand in debt. I dunno how you can call me ghetto when I don't own any banks sh*t. I think Euro cars just bring out the retardedness of young people - there's quite a lot down here.

I prefer an Aston Martin... not as fast as either... but it's the "sleeper" supecar. Not a lot of people will know what it is, and it's not as much as an attention grabber, thank God. The best part is that they're even rarer down here.

In the end... they're both nice cars... but when I watch Le Mans, I cheer for the C6R monster... quite a unique and ferocious sound when compared to its opponents. Hence the desire for a Z06.

I know what you mean about SoCal kids West, I lived there for five years and those stupid kids drove me nuts. So what they own a Beamer, most of those cars are crap anyway. Or at least they are after those kids treat them bad and don't take care of them. I have a lowered Silverado and I take da*n good care of it. Things are worth more when it's your money paying for it.

My favorite car of all time is the 70 Chevelle. Not the fastest or the best handling car. But hearing a 454 belch out it's wonderful V-8 song is awesome, to me anyway. That car has sex appeal.

Are we ever going to get back to the subject of this thread?

JPMs' wreck wasn't that bad. It just looked bad because of the fire. Which is really rare these days. The safety in NASCAR is second to none. The reason most people wanted to see him pit the car was that a NASCAR pit stop is a heck of alot more difficult and hectic than an F1 pit stop.

Well Ray, I sincerely hope you get over the unemployment situation and find a job soon. One company I worked for twenty years decided to downsize and I found myself out of a job. I know how it feels, and it hurts for a very long time.
I have lived in both Europe and North America, and have owned cars as opposite as an Austin Healey Sprite to a Lincoln MK VII. The things is, in their respective elements each shine, but suck at others. In Europe there are uncountable tight streets and cobblestones, while in USA, wide open roads are the norm. So what happens is that a car optimized for one continent looks like crap out of it's element. And people form incorrect assumptions, they usually don't get to experience the car in it's true element.
The Corvette has strengths and weaknesses, where in Europe those defecits really make a differences. The fuel mileage, the huge V-8, other factors make the Corvette very unnactractive in a place with high gas prices and high costing licencing fees, but in the USA that kind of stuff doesn't exist.
Each environment requires a different solution. If I won the lottery and lived in Europe, a Ferrari F430 might be my choice. But in the USA a Corvette would be an adequate response.

Since you insist on arguing about that...

Haven't you heard about the issues big US car manufacturers are having? If they are so good, how come they don't sell even with the cheap prices and 0% financing? I believe Toyota Camry has been the best selling car in US for a decade now. And seems the imports are doing better and better as time goes by. Am I wrong?


FWIW, I never said that Z06 or whatever was bad. I just said I wouldn't buy it over here.

Aygo is also a great car for what it is, but would you buy one over there? If you don't, do you think I should call you names and assume you bash it just because it's not a US car?

It's a big world out there. A thing that works in one place doesn't necessarily work elsewhere. People make choices based on their needs and it doesn't mean they don't value things that they didn't choose.

I asked for forgiveness for being rude, and apologized. What else do you want pRo?

If a car outsells another, so what? That doesn't mean it's better than the other one by any means. Look at F-150s. They are nice trucks, but generally poorly designed next to a Chevrolet. Dodge trucks are even worse, but they outsell Chevy because they are cheaper. In reality, you get what you pay for. They could be better, I agree. That being said, it doesn't mean the others are inferior.

No, I wouldn't buy an Aygo. Not big on small cars. Personal preference. I do have an MGB. But it's a classic, that's why I own it. I've said before I won't drive until it is safe to do so, and then I won't drive it in traffic. If I were to ever get hit, I would be creamed. They would pick me up with a bucket and a sponge. That's why I don't like small cars. Hard to see, don't have the power to get out of trouble if it comes up, and if you get hit you're pretty much dead. Although that may only be true here where the cars are by majority pretty big. I won't buy a Prius either. It's a stupid car. Sure the technology is great, but it substitutes one type of emission for another. How do you think the batteries are made and where will they go when they die?

But I won't bash the Aygo , until I see the way it's designed, nor will I bash you for suggesting that I look at it. I only made remarks that Euro cars are not any better or worse than American cars, and that it seems to me that everyone who says one good thing about US cars quickly follows that with 5 bad things. I just said the overall consensus is that American cars are junk, poorly designed and archaic. Which is a snobby mentality towards another brand of car just because it's not a BMW, Porsche, or any other nice European car. So yeah, I was rude about it because I'm tired of the way people talk about US made cars. Always talking down about them gets old.

I'm trying to end this argument. Repeatedly. I don't care anymore, it's already come to an impasse and we aren't going to get anywhere continuing down this road. I want to get back to talking about JPM. Is that so bad a request?
