A great deal of generally very ill informed stuff...
Jesus....
Yes, oddly enough I'm familiar with the way gearboxes work.
No, German cars are not automatically better than cars from any other nation. Mercedes for instance went through a sustained period where they exhibited build quality and corrosion resistance that was so bad it made 1970's Alfa Romeos look thoroughly robust.
I've owned French cars, many of them. None of them has proven to be a money pit of reliability or quality issues. My last one cost me £7000 to buy new, and used the sum total of 2 part exhausts, 1 catalytic converter, 3 sets of tyres, 2 radiators and three sets of brakes in over 100k miles and 18 years.
If you want to talk about dynamics and control I can point you to any number of Japanese and indeed French cars that make the Audi A3 feel like it's overweight, over-priced, underdamped, and set up with a chassis thats heavily biased toward 'feeling like an Audi' i.e. Nose heavy...
I've driven cars of all types and ages on the continent, from a 40 year old 1.0 mk1 Ford Fiesta, through 50's racecars, kitcars, trucks, 80's supercars, modern supercars, and everyday Japanese, Italian, British, American and German cars all over the continent, from Denmark to Gibraltar. The best car I've ever driven for 'freshness' was a Mazda 6, so debunking the theory that the Germans superior steel and one touch windows is key to a happy life. Oddly, none of these cars ever failed through any kind of metal fatigue issues.
Alfa didn't pull out of the UK, Lancia did.
American manufacturers had a proven record of cheating their own emissions laws long before VAG or Toyota showed up.
Americans can and do build decent engines. They can now build decent cars too. Your stereotype, whilst fun for winding up Americans, is hopelessly out of date.
If you want to discuss thermodynamics, pleas go and buy a book and study the subject first.
Try to construct a reasoned and researched argument, since most of what you are saying is complete bunk, and if there's an intelligent intellect there trying to make a point, it's really not coming across that way...
