The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and equalization. http://en.wikipedia.org/wiki/Suspension_(vehicle) Suspension is the term given to the system of springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two.[1] Suspension systems serve a dual purpose — contributing to the vehicle's roadholding/handling and braking for good active safety and driving pleasure, and keeping vehicle occupants comfortable and reasonably well isolated from road noise, bumps, and vibrations,etc. These goals are generally at odds, so the tuning of suspensions involves finding the right compromise. It is important for the suspension to keep the road wheel in contact with the road surface as much as possible, because all the forces acting on the vehicle do so through the contact patches of the tires. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear. The design of front and rear suspension of a car may be different...

1. The hydropneumatic suspension solves all problems with car suspension. It has the most comfortable ride of all systems, yet it can not be "down-loaded". It has active ride-hight correction, irrespective of load, thanks to the high-pressure hydraulic system (powered by the engine). You can even vary the ride-hight of the vehicle. The damping of the system is also progressive, according to speed, rough roads, corner-turning, etc. Many DS drivers talk of a soft, yet firm system. The roadholding is also, of course, excellent. It really has no rivals...
2. I never lived during this time period, so it is fun for me to watch these videos and get a taste of what life was like back then!
3. Not right now, but I'm always looking.
4. you never cease to amaze me dude. Say, do you have any videos of the Inventions developed by Nazi Germany during WWII? I have always found that interesting.
