In Italy in the 1960s, if something was Abarthizzata, it was superior to the norm. As one Italian author put it, "Abarthizzata could be...used indiscriminately to describe a particularly well-endowed girl or a garden tool made more efficient as a result of some ingenious alteration." The more common use for this adjective was to describe cars, of course, but it's evident that a word with such ubiquitous applications could only come about from a truly popular source. That source was Carlo Abarth.
Though born in Austria, Carlo Abarth lived long and prospered in Italy, where his number one goal over the length of his auto-making career was to win races. His earliest efforts, running Cisitalia's racing team, produced impressive race wins. When Cisitalia floundered in 1949, Abarth took several of the chassis and built his first automobiles. His engines were built on Fiat blocks but were blessed by his unique ability to generate maximum power out of minimum metal. Until 1956, his chassis all wore custom bodies provided by Italy's finest carrozzerie, from Allemano to Zagato. While cars and the race tracks were his passion, his bread and butter work was mufflers and high performance exhaust systems.
In April 1956, Abarth's first Fiat 600-bodied automobile appeared at the Turin Salon. The stock Fiat 600 had taken the country by storm the previous year; it was Italy's first new post-war people's car (the original "people's car," the Topolino, had been updated in 1952, but still looked hopelessly pre-war). The 600 was affordable, and it was a huge success. For that April show, Abarth lined up six identical Fiat 600 Berlinettas (sedans) that hid under their modest pearl-grey sheetmetal the true star of the show: the Abarth 750 engine. Abarth had transformed Fiat's diminutive 600cc 22-bhp motor into a fire-breathing 747cc 51.5-bhp race-winner. While the design world and international automotive press went gaga over the custom-bodied 750s that appeared alongside those humble sedans (especially the Double Bubble Zagato), the Italian consumers did the opposite: here, finally, was a race car they could afford.
Well, some of them could afford. At first, the process of converting the 750 Berlinettas at the factory was slow and costly. Abarth's exhaust system business kept his small staff too busy to satisfy more than a few Berlinetta customers. All that unsatisfied demand was hard to ignore. So instead of hiring more staff to take apart, modify, repaint, then reassemble all those cars, Abarth decided to offer the conversion as a kit.
The 750 had an illustrious racing career in a mind-boggling array of bodies, both kit and custom, before Abarth went to work on his next great engine. In late 1960, Fiat introduced the 600D, which increased the stock four-cylinder's displacement to 767cc. In Abarth's hands that number jumped up to 847cc. Carlo stretched the 600's 60mm bore to 62.5mm and lengthened the 63.5mm stroke to 69mm. Maximum speed rose to 87.5 mph (as fast as saloon cars with twice the engine size) and torque increased from 5.5 kgm (39.8 lb-ft) to 7 kgm (50.6 lb-ft) at 2800 rpm.
The car was designated 850 TC, for Turismo Competizione, and to meet homologation requirements to race in the "Touring Competition" class, Abarth had to build 1,000 units, which he (apparently) did by the end of 1961. How many more 850 TCs were built--as cars or kits--is anyone's guess. The kit itself included a crankcase with larger diameter bearing supports, a tempered steel crankshaft, lighter and stronger connecting rods, and lighter pistons with smaller skirts. A new camshaft altering timing and valve lift, a Solex 32 PBIC carburetor and single-pipe manifold wed to the famous Abarth silencer joined valves, valve springs, gaskets, air filter, clamps, and miscellaneous screws to complete the kit. Those all important emblems, grilles, badges and lettering had to be ordered separately. The front radiator (seriously needed to cool the larger motor), perforated disc wheels and larger brakes (definitely recommended!) were also extras obtained for a price.
Despite the price of the kit and the add-on prices for essentials like the radiator and brakes, it was still cheaper for the average Italian to purchase the kit, and do the work themselves (or in cousin Giuseppe's shop) than to pay Abarth to build one. The Abarth-built cars did benefit from extra touches, though, like strengthened front leaf springs, larger rear springs, front disk brakes, the extra radiator mounted below the floor pan and caliper hinges that allowed the engine lid to sit open--a touch that the competition thought was for extra cooling, but in fact was a trick that increased the bubble car's aerodynamics considerably. Abarth-built cars also usually received a fancy three-spoke steering wheel and Amadori or Campagnolo wheels. Even though each started with a standard Fiat body, every Abarth-built car was different.
On the race tracks, it didn't matter if your 850 TC was built on Corso Marche in Turin, or if you'd built it in your own backyard. Depending on the compression you chose, your new Abarth 850 could crank out 52 bhp (at 6000 rpm), 55 bhp (at 6200 rpm) or 57 bhp (at 6500 rpm). These little sedans racked up victories right and left, helping Abarth win the Manufacturer's Championship 7 years running, from 1962 to 1967, and the European "Challenge" Touring 850 Class in '65, '66 and '67. When the 55 bhp version won the tough Nurburgring race in 1963, the cars with that motor henceforth wore that German track's name on their trunk lids. The later 57 bhp version first wore the nickname SS, then took on the word "Corsa" (Italian for race) and competed in Touring's Group 2 and Group 5. The last two 850 TC/Corsas had compression ratios of 12.5:1 and generated 78 bhp at 8000 rpm with the single Solex carburetor, or a whopping 93 bhp at 8000 rpm with two Weber 40 DCOE 2s. Those Group 5 Corsa cars reached top speeds of 190 k/h (118 mph) and wiped out most of the competition.
Thirty years later, Fiat-Abarth 850 TCs are coveted collector cars. Later Corsa models with race histories sell for $50,000 and up. Though there's a small group of Abarthisti who can tell an Abarth-built TC from an Abarth kit car or Fiat replica, the majority of aficionados respect the fact that these cars were meant to be enjoyed by the many, not the few. So there's no shame in building a replica, even if there are no true Abarth parts in the final product, as long as the work is done with respect for the original design, and the owner is honest about it. The car featured here is a perfect example of one way to do it right.
This car's owner, Andrew Schank, is a body-and-paint man by trade, and Italian car aficionado by passion. He'd been searching, in vain, for one of Abarth's coachbuilt cars, and decided that an affordable 1964 Fiat 600 would make the perfect base for an 850 TC conversion.
Andrew started with what for him was more familiar territory: the body. The California car had little rust, but after the car was stripped it revealed some sections he decided to replace with fresh metal. Then the "Corsa" modifications began: he flared the fenders to fit 5x13 magnesium wheels and brass-hammered out the rears to clear a 165/65-13 tire. The paint scheme called for red--since the original 600 was red--but Andy exercised his skill on the elaborate checkerboard roof. He told me "the roof was unbelievably difficult. I painted the white first, then laid out a grid on the roof and spent a long time taping off every other square--117 squares total. After I sprayed the black, I had to hurry and untape everything so that the paint wouldn't dry too much and pull off in strips with the masking tape." Was it worth all the work? "The roof makes the car, and everyone who sees it loves it."
With the car painted and badges and trim all secured, it was time to install an engine. But which one? No Abarth kits are available on either side of the pond, and most Abarth engine parts are only available well used at very high prices (remember, these are race motors--they led very active lives). The only exception to the well-used rule is the more modern Abarth Autobianchi A112 engine. It's considered a true Abarth conversion (and qualifies for vintage racing in Europe, where these cars are more plentiful), as Abarth was working on its design before he handed the company over to Fiat in 1971. The Autobianchi Abarth engine came in two sizes, a hot 982cc and a scorching 1050cc. Andrew test drove a car powered by the 1050cc 70-bhp unit and was impressed with its power. He located a brand-new, still in the box long block at Fiat Plus, but decided that the $2,800 price tag was too high.
That left several Fiat options. The 600 or 600D, without Abarth's tweaks, wouldn't be much of a street racer, so Andrew decided instead to "Abarthize" a Fiat 850 903cc motor. Though this required reversing the rotation of the motor, the parts and how-to required for this trick were readily available. He decided on a mild street cam from a stock European Fiat 127, which allowed for lower compression and better street driving. He finished it off with a Weber 28-36 DCD, a diaphragm clutch conversion, performance manifold, and Ansa exhaust that looks just like the original Abarth unit. He lowered the car by 1.5 in. front and rear, after an entire front end rebuild. Discs replaced the old drums in front and the front radiator was provided by a unit from an 1100cc motorcycle which fit handily in the spare tire well.
When all the bugs were worked out, he had the car tested on a chassis dyno, and the 58 bhp at 6000 rpm not only beat the original 850 TC Nuerburgring's 57 but bettered the stock 903 motor by seven. Andrew has already logged 3500 miles on the car, and has no fear of California traffic jams. In fact, he says the car is "so much fun to drive I often get in and drive around the neighborhood for no particular reason." He doesn't vintage race, but takes it often to Bay Area concourses, where he's the first to admit the car's an Abarth 850 TC replica. Recently he was at one of those shows with the car when an older Italian gentleman approached. "When I was growing up in Italy," he told him, "you couldn't own a more desirable car than a Fiat 600 Berlina Abarthizzata." Thirty-four years later, nothing has changed.
