Sprint Veloce Alleggerita 750E

As of 8/11/10 there are 39 Sprint Veloce’s on the register that are confirmed to exist.  21 of the cars on the register have links to photo sets.

l19Sprint Veloce Alleggertia racing in France. Check out Saffier de Bard, lots of great period pictures to be found.
The appearance of the Sprint Veloce was inevitable. Creating an even faster version of an existing sports car to take racing was standard practice among auto makers who raced in the 1950’s. This seems to be especially true of the Italians who perfected this approach to car building. You can almost imagine the scene after Alfa debuted the Giulietta Sprint in the racing world only to be beaten by Porsches in the same class.

The first line is the Fusi stated range for the year and the following are numbers on cars that have been reported. d’Amico and Tabucchi have some differences listed and I’ll try and work them in later. Eventually as enough data points become available I’ll modify or remove the year/range headings and provide a better view of the flow of things at Alfa and particularly Bertone in through these production runs. An entry ending in Ref. is for an important car which may or may not exist.

30661Veloce’s were marked 750E here on the build plate along with the body and engine number. 750 Veloce’s all have 1315*3XXXX engine numbers.

30659Bertone body numbers for the Veloce’s were changed to start with 77 rather than the 65 used on Normales. The total of ~610 comes from the body number explanation for 750B’s. I’ve never seen a non lightweight Veloce below about chassis number 6000.

badges svBody shape of the Alleggerita Sprint Veloce’s is the same as the Normales. Aluminum doors hood and trunk were used, but not necessarily on all of these cars. Badges were updated as seen here.

bigiThere was only one guiding principal at work on the Sprint Veloce: go faster (and beat the Porsche’s)! With this in mind, both sides of the power balance equation were adjusted. The engine power output side of the equation was increased by using Weber 40DCO3’s, higher lift cams and a shaved head (among many other things), and the various factors on the other side of the equals sign that are multiplied by velocity were reduced. Or, if you prefer, the engine was tuned to increase power and the rest of the car was tuned to remove weight, rolling resistance and drag.

pass doorCompare this to a Normale door panel. The window itself going from glass to plexi doesn’t save much weight, but the winder mechanism and associated brackets and controls are massively heavy for the job they have to perform. Almost looks like a British roadster removable side curtain. This particular car was ordered by the prince of Sweden new with various non-lightweight feature as a hopped up road car, rather than the out and out racer the Veloce was originally intended to be.

bighThe tuned engine of the Veloce had a higher redline (rev limit) so they made a special tachometer with a 6600 rpm redline that went up to 8000 rather than the 6200 redline/7000 limit of the Normale. Other interior details included the omission of the choke knob and glove box door (this car was specially ordered to include both) and supposedly lighter weight construction seats.

under backVeloce final drive was changed to 10:41 from 9:41 to take advantage of the increased power and provide for a higher top speed. The typical use for a Veloce was a race like the Targa Florio or Mille Miglia, a long distance road race, so the fuel capacity was increased from 56 liters (14.8 US gallons) to 84 liters (22.2 US gallons). Thats 28 Kilograms or 61.7 pounds more fuel carried. These little cars are all about conservation of momentum so I doubt it mattered much. Note that most of the volumetric increase was achieved by growing the tank in the direction of the rear axle keeping it low and as near the center of the car as possible. This growth of the fuel tank necessitated the rear emergency brake cable and yoke type set up seen here.

latest10_20_08 252While this car is a fake Veloce from back when owners felt the addition of side draft Webers allowed for the use of this badge, they did get the rear circular badge correct in that they left off the chrome over brass base that goes under this badge. A detail that is usually overlooked by restorers of real Veloces, who tend to add this little trim bit.

  1. i have a 750E A utotelaio 1493-03897
    motore AR-1315-30376
    aparently race in Venezuela San Cistobal to Caracas in 1957 -30-11 i think that the engine it is one of the 10 engines special tune byy Alfa Romeo i will apreciate any comments
    thank Landy

      • Antonio i would be interested in sell it if i could find some additional information
        the engine it is a factory special the carter it is rectangular cast aluminum
        whit wave breaker 4 to 1 header out in left side ,light weight rads red heads
        valve covers plexiglas windows aluminum dors hud tronk light seats campagniolo rims

  2. i briefly owned a ratty sprint veloce in L.A. around 1972. I loved alfa’s and my first car was a 1960 sprint coupe, I purchased with paper route money. I then bought a white 1960 spyder veloce and lots of other cars. When I found out about the lightweight one I spent quite a lot of time trying to convince to owner to sell it to me. I kept it about a year and then passed it along to an older collector. I new I did not have the resources to restore it and could see it was a rare car. It had: 750 veloce motor, alum doors with plexi windows, leather racing seats, alum hood and trunk, borrani wires with knock offs. I knew it was a special car. Probably out there some where now.

  3. Hi there!
    just to let you know…I bought the sprint veloce alleggerita sold in London ( RM auctions)
    matching numbers for chassis and engine.
    (Sprint 750E 1493*03808. Italy. ’08 MM.)
    Will send you some pics.
    Thanks for your site, it’s very nice, and many informations!
    Take care,
    Sandrine

    • Hi SANDRINE, I was interested in buying that car but I did not. Instead you did fine. So when the car will be fully fixed following the original A.R. specifications I will buy it from you, of course at the reasonable price, considering the work you will carry on. Please, let me informed about. Best regards!! If you like, you could send me some pics (better if HD). Thank you!

  4. Good evening,
    now, after 5 years, it would be nice if you, when you will have time, update this article. Moreover, you should mention that, among the improvements A.R. did to transform the Giulietta Sprint Normale into the Sprint Veloce lightened, there was the use of a couple of double body Weber 40DCO3 carburetors instead the small single Solex. This was much more important and determinant then the elimination of the lid of the gloves box….. Thank you very much.
    Best regards,

  5. I do not know when and why the Alfa Romeo Giulietta Sprint Veloce 750E, first series, 1956 began to be popularly called “lightweight”, in english. This term is wrong and also it is not included into the original official name given by A.R. to that version and reported above. To distinguish first, second series and Confortevole here in Italy has been used the term “alleggerita” signifying that the car is lighter than the original 1954 Sprint (≈ 75/80 Kg less).
    The English literal translation of “alleggerita” is not “lightweight” but “lightened” even if the difference is subtle.
    So, I would suggest (to the media first), to start calling and identifying that version as “lightened”. Moreover, because in some way that word become integrated as part of the proper name of the car, the best option in my view would be to add to its name simply “alleggerita”, which does not have to be translated, as it is usually done in this Alfa Romeo Giuliettas blog. We do not say Alpha Romeo Juliet Sprint Fast…..! Thank you.

    • Rob,

      “Lightweight” is the only term I heard for the first Sprint Veloce 750E’s for a few years. Alleggerita came to my attention around the time I started the blog. I think it has to do with how English is used in the US – we don’t think of things in terms of the process (lightened), but the result of the process (lightweight). Alleggerita is my preference as well.

      Matt

      • Thank you Matt,
        I understand differences between a process and its result, as well as differences between UK and US use of some terms. In few words, lightened means alleggerita and lightweight means leggera. Because here, in the GSVA birthplace, that version is almost always named “alleggerita” it make sense, just translating, to call (in UK or US) lightened, because lightweight is leggera. The difference is very slight but leggera is very general term (leggera vs what?) whereas alleggerita (lightened), the process, in this case means lighter vs the basal version, the Giulietta Sprint Normale. It has been just an attempt to unify the term which is part of the proper name of the car that, as we can see here, can be named in several, potentially confusing, ways.. Rob

      • Rob,

        I am in the process of a significant update to this page, and the site in general. Among my tasks is a glossary page, where I explain official versus colloquial etc. The various unofficial names will be explained and hopefully everyone will be satisfied rather than confused!

        Matt
