U.S. 348s have functioning on-board OBDI engine management systems, though European variants need to have light bulbs placed into the dash to activate this trouble-shooting feature. Similar to the Testarossa but departing from the BB 512 and 308/328, the oil and coolant radiators were relocated from the nose to the sides, widening the waist of the car substantially, but making the cabin much easier to cool, since hoses routing warm water no longer ran underneath the cabin as in the older front-radiator cars. This also had the side effect of making the doors very wide. All Ferrari 348s use racing "dry-sump" oil systems to prevent oil starvation at high speeds and in hard corners. The oil level can only be checked (accurately) on the dip-stick when the motor is running due to this setup.
Likewise, all 348s have independent, corner-adjustable ride/height/weight adjustment abilities built in to each suspension, as well as a removable rear sub-frame to speed up the removal of the engine for maintenance. More than 8,000 348s were produced, and the car's straked side air intakes give it a Testarossa look (because of this it is sometimes considered a kid brother to the Testarossa).Source: Wikipedia.
