The 348, badged 348 TB for the coupe (Berlinetta) an 348 TS (Spider) for the targa versions, features a naturally aspirated 3.4 litre version o the quad-cam, 4-valve per cylinder V8 engine which wis originally foond in the 288 GTO sports caur. Thus the model name, 3.4 litre 8 cylinder engine. The engine produced 300 hp (224 kW) at launch an sits longitudinally with a transverse gearbox, like the Mondial t with which the 348 shares mony components. This wis a major switch for Ferrari, with maist previous small Ferraris uisin a transverse engine with longitudinal transmission. The transverse gearbox give the model it's "T" on TS an TB.
All 348s wur shipped with dual-computer engine management with twin Bosch 2.5 Motronic ECU's, double-redundant Anti-Lock Braking systems.
Likewise, all 348s wur shipped with on-board self-diagnosing Air Conditioning an heating systems.
U.S. 348s hae functioning on-board OBDI engine management systems, though European variants need to hae light bulbs installed into the dash to activate this troubleshooting feature.
Similar to the Testarossa but departing frae the BB 512 an 308/328, the oil an coolant radiators wur relocated frae the nose to the sides, widening the waist o the caur substantially, but making the cabin much easier to cool, since hoses routing warm water no longer ran underneath the cabin as in the aulder front-radiator caurs. This also haed the side effect o making the doors very wide.
All Ferrari 348s uise racin "dry-sump" oil systems to prevent oil starvation at high speeds an in hard corners. The oil level can anly be checked (accurately) on the dip-stick when the motor is running due to this setup.
Likewise, all 348s have suspensions independently adjustable for ride height, as well as a removable rear sub-frame to speed up the removal of the engine for maintenance.
Late versions (1993 and beyond) have Japanese made starter motors and power generators (to improve reliability),as well as the battery located within the front left fender for better weight distribution.
Nearly 9,000 348s were produced, and the car's straked side air intakes resemble those of the Testarossa. Also, 57 "Challenge" models were made for owners who wanted a more "track-ready" car.
This vehicle also served as a test mule for the Ferrari Enzo. Three o these wur made.
