Fiat Dino Coupe

In the mid 1960s Ferrari was facing a rule change in Formula 2 racing which would prohibit use of any engine that was not manufactured in at least 500 units. As Ferrari wished to continue using its 4-cam V6 "Dino" racing engine (named after Enzo Ferrari's son who died rather young of an illness and had a small role in the engine's development) that it had raced in various displacements in the 50s and 60s, they approached Fiat and asked that Fiat produce a road car around the engine so that over 500 units would be produced.

Fiat solicited designs and chose Pininfarina to design the spider and Bertone the coupe and the cars were released in 1967. These cars sported the 65° V6 Dino in 2.0L displacement with aluminum block and heads, 9 to 1 compression, fed by three downdraught Weber twin-choke carbs, producing 160hp (DIN) at 7200 RPM, 120 ft.lbs. of torque at 6000rpm and a top speed of 127 mph. This engine is the same unti used in the "Ferrari" Dino 206. [When the cars were developed, both the "Ferrari Dino" and "Fiat Dino" were intended to be cars in a separate line than the two car makers, known simply as "Dino". However, Fiat wished to cash in on the reputation of Ferrari and its Dino engine to boost its own reputation and released the coupe and spider with Fiat badging, and many Dino 206 and 246 have taken to putting Ferrari logos on their cars though none were originally fitted].

The cars featured a 5-speed all-synchromesh transmission, independent front suspension with "live axle" suspension in the rear, limited slip differential, disc brakes all around with vacuum servo, 6.5" rims fitted with Michelin 185-14 XAS tires. The early cars were rushed to market, and they were plagued by problems such as plug fouling at city speeds, and in case of the spider, poor overall build quailty for a car of this price. Some of these problems were eliminated later in the 2.0 series, but it wasn't until the 2.4 series came out that the cars really lived up to their heritage.

The biggest change from 2.0 to 2.4 was naturally the engine. The block was changed to cast-iron and thus the liners were eliminated. Yes, the weight of the engine incresed, but the performance increase more than made up for this. While the 2.4 weighs 9% more than the 2.0, horsepower is up 12% and torque up a whopping 25% (and comes at lower rpm). The 2.4 is rated at 180 hp DIN (or 188hp using the modern SAE) and 159 ft. lbs. at 4600rpm. The transmission was replaced with a stronger unti made by ZF. The shift pattern was changed and follows the traditional Ferrari pattern - Reverse top left, 1st is down on bottom left, and the remaining higher gears behing in an H pattern. The reasoning behind this is that a car being driven hard must leave no doubt about the accuracy of changing from 5th to 4th gear, a change that will be made frequently. The pattern also slows the shift from 1st to 2nd. While inhibiting stop light racers, it will prolong the life of the gearbox since the jump from 1st to 2nd ratio is always the largest jump in ratios and care here should be taken anyway.

The rear suspension became a fully independent system with an anti-roll bar, shock absorbers being reduced from 4 to 2 and heavy-duty RIV components were used. The gas tank was englarged slightly from 66 to 70 litres (about a gallon larger). The clutch was also changed from a hydraulic system to a cable, the radiator was enlarged, the rear brake discs were enlarged to 11.01 inches, front calipers became two pot Girlings (same as on Maserati Ghibli and DeTomaso Pantera), and the brake servo was changed to electric so that if one's car stalled, he would still have brake assist until the beast was brought to a stop. Wheels were the same 6.5 x 14 Chromodoras, but tire width was increased to 205mm from 185mm. Campagnalo 7 or 7.5 inch wheels were available as an option but few buyers made this choice. The interiors were redone as well and though the overall styling of the exterior didn't appear to change much, in reality the cars share few panels.

This 2.4 engine in the Fiat Dino is also used in the "Ferrari" Dino 246. This last fact brings much joy to Fiat Dino owners as the high value of the Ferrari model assures that engine parts will be remanufactured for many years to come.

424 2.4 Spyders were built and 2414 2.4 coupes. This means that the Fiat Dino 2.4 cars are actually rarer than the Ferrari 246GT and GTs of which a total of 3761 cars were produced.
