History

The following section is an excerpt from Wikipedia's Ferrari 348 page on 6 September 2021, text available via the Creative Commons Attribution-ShareAlike 3.0 Unported License.

The Ferrari 348 (Type F119) is a mid-engine V8-powered 2-seat super car produced by Italian automaker Ferrari, replacing the 328 in 1989 and remaining in production until 1995. It was the final V8 model developed under the direction of Enzo Ferrari before his death, commissioned to production posthumously.

The 348, badged 348 tb for the coupé (Trasversale Berlinetta) and 348 ts for the targa (Trasversale Spider), featured a naturally aspirated 3.4-litre version of the quad-cam, four-valve-per-cylinder V8 engine. As with its predecessors, the model number was derived from this configuration, with the first two digits being the displacement of the engine and the third being the number of cylinders. The engine, which had a power output of 300 PS (221 kW; 296 hp), was mounted longitudinally and coupled to a transverse manual gearbox, like the Mondial t with which the 348 shared many components. The "t" in the model tb and ts designations refers to the transverse position of the gearbox. Overall, 2,894 examples of the 348 tb and 4,228 of the 348 ts were produced.

The 348's styling differed from previous models with straked side air intakes and rectangular taillights resembling the Testarossa, stylistic themes reminiscent of the F40, the world's fastest production car at the time, and other prestigious Ferrari models of the past. The model was also the final design overseen by chief stylist Leonardo Fioravanti, known for such designs as the F40, Daytona, 512 Berlinetta Boxer, 288 GTO P5, P6 and others. The F355 that succeeded the 348 returned to the styling cues of the 328 with round tail lights and rounded side air scoops.

The 348 was fitted with dual-computer engine management using twin Bosch Motronic ECUs, double-redundant anti-lock brakes, and self-diagnosing air conditioning and heating systems. Late versions (1993 and beyond) have Japanese starter motors and Nippondenso power generators to improve reliability, as well as the battery located within the front left fender for better weight distribution.

All 348's have OBD-I engine management systems, though European and general market variants do not come with the self-test push button installed, which is needed to activate this troubleshooting feature.

Similar to the Testarossa but departing from the 512 BB and 308/328, the oil and coolant radiators were relocated from the nose to the sides, widening the side 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.

The 348 was equipped with a dry-sump oil system to prevent oil starvation at high speeds and during hard cornering. The oil level could only be accurately checked on the dipstick when the engine was running due to this setup. The 348 was fitted with adjustable ride-height suspension and a removable rear sub-frame to speed up the removal of the engine for maintenance.

348 Serie Speciale

Between 1992 and 1993, Ferrari made 100 limited edition units of the 348 Serie Speciale of its tb and ts versions. It was only made for the US market.

The main technical modifications consisted in a revised engine which produced 316 PS (232 kW; 312 hp) at 7,200 rpm, a wider rear track (50mm), a free-flow exhaust system, a shorter ratio final drive and Pirelli P Zero tyres. Ferrari indicated a 0–97 km/h acceleration time of 5.3 seconds and a standing ¼ mile of 13.75 seconds.

Several modifications were made to the exterior as well: new front spoiler to optimize aerodynamics similar to the F40, new front grille with the chrome prancing horse, bumpers and rocker panels in body colour, engine cover in body colour, modified taillight assembly and new rear grille with the chrome prancing horse.

The cars were offered with F40 style sport seats in Connolly leather with the regular seats included as an option. The door panels were also modified and made of leather. Each car was numbered (1 to 100), with a 348 Serie Speciale plaque on the passenger's side door-post.

348 Challenge

The Ferrari Challenge was initiated by Ferrari Club Nederland founder and President Hans Hugenholtz and designated for the Ferrari 348; the series debuted in 1993 and included the Italian and European series. The engine used in the participating cars was similar to the road going GT models introduced in the same year with the only noticeable changes being the slick tyres, new body kit, better brake-pads, roll-bar, smaller battery in a different position and seat belts. In 1994 the G-spec engined cars had to be modified with the H-spec cylinder heads and injection system. The cars were mostly modified by dealers by installing factory supplied Challenge kits. The car's final season was in 1995 and was replaced subsequently by the F355 Challenge.

348 GTB, GTS, Spider

In late 1993, the 348 was revised, featuring subtle styling changes (front grille, rear chrome Cavallino and removable seat cushions) and more power, this time 312 hp (233 kW; 316 PS) and 320 PS (235 kW; 316 hp) (Europe) from the same 3.4-litre engine, with an improved engine management system - Bosch Motronic 2.7 and a new exhaust system (single muffler).

The revised cars are called 348 GTB (252 made) and GTS (137 made) and were presented to the public as the 348 GT versions, equipped with the F119H engine (as opposed to the original F119D and US F119G). The F119H engine had an increased 10.8:1 compression ratio as compared to the F119D & F119G's 10.4:1 compression ratio, taller intake plenums, a larger intake compensation valve, fuel pressure raised from 3.4 bar to 3.8 bar, and different camshaft timing.

For these models, both the engine cover and lower body skirts were body-coloured instead of black, and the rear track was one inch wider due to the mounting area, on the inside, of the rear wheels being thicker. The suspension geometry was revised which greatly enhanced its handling, ride and body control. The fuel tank was made smaller in order to reduce overall weight and provide space to improve chassis rigidity; it now held 88 L (23 US gal; 19 imp gal).

A convertible variant called the Spider was introduced in 1993 and was Ferrari's first series production convertible model since the Daytona Spider. Visual changes for the spider included body coloured lower cladding pieces, a specially designed engine cover and a manual folding soft top. The rear track was increased by 50 mm (2.0 in) compared to the 348 tb. The Spider used the same engine as the 348 GT models and hence benefitted from the increased power output. A new transverse mounted gearbox with modified gear ratios was installed to ensure better acceleration times and shift response.

348 GT Competizione

In 1993, Ferrari presented a light weight 348 GT Competizione variant as a homologation version for competing in the GT Championship. Safety equipment such as a tool kit was carried over from the 348 Challenge. The braking system was derived from the F40 Evoluzione model. The cars also had modified racing suspension and exhaust system. The engine had a power output of 320 PS (235 kW; 316 hp) at 7,000 rpm and 324 N⋅m (239 lb⋅ft) of torque at 5,000 rpm, consistent to standard late 348 production with the F119H engine. Only 50 were made, including 8 Right Hand Drive models. Special features included a specially trimmed steering wheel indicating the number sequence in the production of the 50 cars, 5-spoke 18-inch Speedline competizione wheels and cloth trim seats with kevlar structure for weight reduction. Aiding further in the weight reduction was the carbon kevlar composite material used for the front and rear bumpers as well as the doors and a light weight polycarbonate rear window. Additional interior trim pieces such as door sills featured carbon kevlar and creature comforts such as air conditioning and sound proofing materials were removed. These changes resulted in a dry weight of 1,180 kg (2,601 lb). The final drive in the gear box was changed to 25/27 ratio for improved performance.
