INTRODUCTION TO GTA -1 part
The Alfa Romeo Giulia replaced the outgoing Giulietta beginning in 1962. Alfa Romeo produced the Giulia in many configurations, some drastically different from other models in the series but all with a unifying thread of polished driving fun. The name 'Giulietta' means 'little Giulia' in Italian, the new car named "Giulia" is a grown-up version of the Giulietta. The car was built with clever touches, and was a superb example of world-leading engineering packed into a small and stylish automobile. The first Giulia sedan models, or "Berlina", models were introduced in June of 1962 and belonged to the 105 series of Alfa cars. The Berlinas were boxy and fairly conservative in appearance, but their design was nevertheless attractive, modern, and surprisingly, much more aerodynamic, with a coefficient of drag of just 0.34. Consider that thirty years later the most aerodynamic car—the Audi 100—achieved a coefficient of 0.30!!

Initially, Alfa Romeo offered only the Giulia TI (or Turismo Internationale) to buyers looking to purchase a new Berlina. This model used a 1,570cc version of Alfa's respected twin-cam four, which proved far more tractable than the 1,290cc unit used in the prior Giulietta. The Giulia TI had a 5-speed transmission, albeit with column-mounted shifter, and most were equipped with power disc brakes all around. The TI was an entertaining car to drive, with fine handling and a sophisticated demeanor, but details like its drab steering wheel, functional but mundane instruments, and column-mounted shifter did little to inspire owners to wring out the potential of the chassis. Alfa Romeo provided buyers with a Giulia Berlina with a more obvious sporty character by introducing the Giulia Super. The Super, introduced in 1965, featured twin Weber carburetors to replace the TI's single Solex, and it had a lovely dash with big dials for the speedometer and tachometer. The column shift was replaced by a floor shift, and power was up slightly compared with the TI. Not to be confused with the Super, a truly racy-ready Giulia Berlina derivative called the TI Super was offered for homologation purposes in 1963. With just 501 produced, it was substantially lighter and more powerful than the initial Berlinas.
Alfa Romeo Giulia Sprint GT, 1963
In 1963, the 105-series Giulia coupe arrived, named Sprint GT and styled by Giorgetto Giugiaro during his collaboration with Bertone. The primary features of the chassis, including the disc brakes, front A-arm suspension, and live rear axle, were all shared , as well as with the Spider models that were still a few years away. Much like the Berlina, Alfa Romeo sold the Sprint GT in many different trim levels, with both 1.3-liter and 1.6-liter engines. In 1968, it produced a lightly restyled Giulia coupé, the new 1750 GTV and later, the 2000 GTV. In addition to the regular production versions of the Giulia Sprint, several specialty models were produced. About 1,000 examples of a Sprint-based cabriolet with four seats, called the Giulia GTC, were produced by Touring at the beginning of 1965, before the two‑seat 105 Spider was introduced. For the track, Ing. Busso created the TZ series, excellent racers with stunning and low-slung bodies; this model was replaced for commercial reasons by a racing version obtained from the Giulia Sprint GT, which was almost identical in appearance to the Sprint GT, yet proved itself as one of the most successful sports cars raced during its time.

The GTA used lightweight aluminum body panels, twin spark plugs per cylinder, a higher compression ratio, and bigger Weber carburetors to create a supremely capable vehicle. Variations of the GTA included the smaller-engined 1300 GTA, the supercharged GTA-SA, and later the GTAm 1750/2000, which had a downright frightening appearance thanks to its menacing fender flares and big tyres. The Spider version of the 105-chassis finally arrived in 1966 styled by Pininfarina. Open and closed cars, two-doors and four-doors, bodies made of steel, aluminum, and even fiberglass, designs from Bertone, Pininfarina, Touring, Zagato, and Alfa Romeo itself. Clearly, the Giulia's history was rich and complicated, full of superb family sedans and successful racing cars. All of these disparate models had something in common, though: they were pure, honest, unfettered Alfa Romeos. And they were some of the finest and most successful postwar cars, both on track and in the showroom. (Continue)
