There was a development department headed by Orazio Satta. The power of the engine easily passed from 65 to 90 hp.
At the 23rd Mille Miglia in April 1956, the Sprint Veloce coupe by Sgorbati Zanelli was first in its category and 11th overall. In this race, Carlo and Dore Leto Di Prielo got out of the way and seriously spoiled their car. Rather than go to the factory, they asked their friend, Elio Zagato, to redo the car. A lighter and more aerodynamic body made it possible to gain 110 kg compared to a standard SV. Combined with careful engine preparation, the SVZ could reach 195 km / h.
The prototype was hired on 2 September 1956 at the Coppa Intereuropa in Monza and turned 2 seconds faster than all its competitors. After this success, with Massimo Leto at the wheel of the first SVZ, in his first race, other drivers of Giulietta brought their car Via Giorgini for the transformation.
It would be impossible now, the price would be astronomical, The time of the special bodies to the unit is passed. These little cars collected an incredible number of great victories which I should like to be remembered; In particular the Cups of the Alps and Liège-Rome-Liège. There were three series of SVZs specific to the years and their construction. The SVZ 1957 was 3 on command of private pilots. One of these cars had bumpers and the three sported the characteristic double bulb roof Zagato (the "Gobba in Italian").
Only 9 of the 18 built SVZs still exist. The car shown # 149-04045 was built from a Giulietta Sprint Veloce of 1957 based on the remarkable work of Adrian Smits in 2004. The car was registered for the first time in Switzerland. Then there are 04045 in Italy with registration number BE-125785 owned by Filippo Piccoloti then PZ99308 in 1976. Purchased by Antonio Ferrenti then by Vittorio Esposito in June 1983 then Vincenzo Glingo. In August 1985 it was for sale by Tony Vico.
In February 1999 for 35,000 pounds sterling and still to sell in April 2000 for 41,000 pounds. Oldtimer of Toffen offered the car in 2001. Tony Vico finally gave 04045 in 2001. The car left for Portugal and not Spain as thought by Adrian Smits. The car was equipped for the road with an Alfa-Romeo 140 HP engine # AR00548 x 87422 and a 5-speed gearbox.
To participate in FIA competitions it would be necessary to re-car the car with an Alfa Romeo 1290 cm3 one of which will be delivered with the car. The current mileage of the car with its 1750 engine is 10.063 kms on the meter.
The current owner bought the car in Portugal in 2007. Estimation 100.000 / 150.000 € Title of community traffic. FIA Files ooooooooo This Alfa Romeo was built from a 1957 Giulietta Sprint Veloce following the excellent work of Adrian Smits. The car was first registered in Switzerland, then in Italy as BE-125785 in the hands of Filippo Piccolo then as PZ 99308 in 1976. It was eventually the property of Antonio Ferrenti, Vittorio Esposito (June 1983) and Vincenzo Glingo. In 1985 it was offered for sale by Tony Vico who sold it in 2001. The car was sent to Portugal, not to Spain as believed by Adrian Smits. The current owner Bought the car in Portugal in 2007.

1957 Alfa Romeo Giulietta SVZ The story behind the SVZ is a fascinating and compelling one. Massimo Girolamo Leto di Priolo was a gentleman racer who took delivery of his brand new Alfa Romeo Giulietta Sprint Veloce in May 1956. Four days later, he drove his new car in the Mille Miglia, where he promptly crashed into a riverbed during torrential rain, essentially destroying the bodywork. Rather than having his car repaired to factory standards, Leto di Priolo had the remains taken to Zagato, who cut the wrecked panels off the platform and built a new body in its place - the SVZ as we know it was thus born. The resultant car was about 150 kgs lighter than the original and more aerodynamic making it immediately very competitive against the factory produced competition Giuliettas, something that didn’t go unnoticed by his fellow competitors (or indeed Alfa Romeo). Following this first car rebuilt for Leto di Priolo, a further 15 or so were rebodied over a period of time to customer order, each being as individual as their owners wished. Three were produced with the trademark Zagato “double bubble” roof, one of these three must be the ultimate car to own. However, the chance of finding then securing one that has undisputed period history is probably unlikely and inevitably expensive. This car, Chassis Number 04045 left the Alfa Romeo factory in 1957 as a regular Bertone bodied Giulietta Sprint Coupe and was duly exported to her first owner in Switzerland. She returned to Italy in July 1975, left Italy again in the late 1990s to a new owner in Portugal where it was successfully rallied (FIA papers from this period on file) before being sold to a collection in Belgium where it was offered for sale and purchased by an English enthusiast in 2014. At some point during her life, she was rebodied as a Sprint Veloce Zagato (SVZ) and although it is not clear when this was done, it was evidently not recently and was certainly before it arrived in Portugal. Upon arrival in the UK, the new owner commissioned a much-needed mechanical and cosmetic restoration. Firstly the incorrect, rally tuned 1750 engine was removed and a replacement 1290cc Giulietta engine was dispatched to specialists “Classic Alfa” for race preparation including a gas flowed head with hardened valve seats, forged pistons, steel rods, race cams etc. The multi shade silver paint (evident in the old FIA papers) was also changed to the current period Alfa colour of Gardenia White. Both the original Zagato-style driver’s seat and the currently fitted competition seat are included in the sale. The vendor has recently secured a brand new set of FIA HTP papers for the car which are valid until 2028. Personally I think the SVZ is one of the world’s most attractive 1950s sports cars. As well as being very rare and highly attractive, SVZs are eligible for some of the world’s most desirable events including the Mille Miglia, LeMans Classic and the Goodwood Revival. If you need regular competitive racing then FISCAR, AMOC ‘50s Sports Cars, MGCC Iconic ‘50s, along with the ever popular Equipe Classic Racing Pre ‘63 race series are all there to enjoy. Then again, if you just want to use and enjoy her as an attractive and very rare road car pop the original seat in and enjoy. She always attracts a huge amount of attention wherever she goes….. This Alfa presents an unequalled opportunity, to enjoy competitive “Dolce Vita” motoring in a car that even as an SVZ continuation model is believed unique in this country, and is thought to be possibly the only double bubble SVZ continuation model in the world with the benefit of “turn-key” status today. To that end, I have the pleasure of offering Chassis number 04045.
