The Alfa Romeo 1750 Spider Veloce made the debut Brussels 1968. Production started May 1967 with 125 pre-series cars. These cars were on the market early 1968.

The 1750 Veloce was the same car as the Duetto and had the same designed items. The headlamp cowls, lights and lenses, the tailpipe, bumpers etc. were the same. Some re-designed exterior parts made it possible to tell the difference.

1. Wheels were now smaller and wider 14 x 5.5in with clip-over hubcaps
   Wider tyres (165/14 instead of 155/15) - choice = Pirelli Cinturato HR/Kleber Colombes/Michelin XAS.
2. Rear-view mirror moved from wing to door. Very early Spiders (150?) had rear-view mirror on left wing like Duetto.
3. Wheel arches changed in profile
4. 1750 badge on boot-lid and the Alfa Romeo with the snake and the serpent. This is in fact the weapon of the city of Milan. The red cross was used among the crusaders.
5. Tear drop side indicators between front wheel and door. Later the indicators were moved forward and re-designed.
6. Optional hardtop reverse angle r/window on later cars. Early ones had the same as the Duetto.-but was this a later option.
7. Engine - incl different carbs + lubrication circuits. Later engines had electric fan. First series of engines had non-offset piston pins. Changed mid 1968 to offset due to engine noise from pistons.
8. New engine mountings.
9. Alternator replaces dynamo.
10. Larger sump.
11. Higher capacity battery 60AH
12. Brake discs (larger 10.5in rear versus old 9.7in) by ATE
13. Pressure regulating valve for rear brakes
14. Twin brake servos (front and rear) - left of engine bay. Early cars had single brake servo by Dunlop or ATE.
15. Hydraulic clutch
16. Higher final drive (4.3:1 instead of 4.555:1) - achieved by more teeth on pinion and crown wheel. Early cars had 4.1:1. Optional ZF LSD
17. Wider rear track
18. Rear transverse anti-roll bar
19. Softer (lower frequency) rear springs + rear anti-roll bar + redesigned transverse links
20. Front suspension: higher roll centre + softer springs
21. Re-circulating ball steering (new)
22. Wood-rim steering wheel (three-spoke)
23. Ashtray (different type)
24. Gear lever gaiter
25. Seats (very slightly different?)
26. Fan switch (to left of main dials)
