This design sounds promising and seems to make sense. The following information is from the website regarding the hydraulic car design:

-------
1. Fuel consumption & emissions
-- 170 mpg - instead of 27 mpg - and more than a comparable reduction in emissions.

2. Safety
-- Active bumpers at the front, rear and both sides absorb the entire crash from a 25 mph impact. The forces the passenger is exposed to are significantly reduced and damage to the car body is basically eliminated.
Individual control of power of each wheel improves the road holding characteristic.

3. Driving comfort
-- The active suspension absorbs most of the road bumps and basically eliminates banking. The lower center of gravity improves the handling.

4. Performance
-- The high power of the wheelmotors provide outstanding acceleration. 0-60 mph in 5 sec.

5. Cost
-- The operating costs are significantly reduced. In long terms, the production costs of the new car will not exceed those of conventional cars.
