RM Sothebys

To Be OFFERED AT AUCTION WITHOUT RESERVE at RM Sothebys' Monterey event, 15 - 16 August 2025. rnOffered Without Reserve | $200,000 - $250,000 USD rnrnOne of approximately 40 examples produced by Autodelta between 1970 and 1971rnBelgian-delivery car reported to have been originally raced by Alfa Romeo BeneluxrnSubsequently raced by West German driver Franz Abraham, as documented by accompanying original ONS-Wagenpass rnPurchased by the current owner in 1988 rnA pure track weapon ideal for vintage racing; fitted with a correct 1,750-cc fuel-injected twin-plug racing enginern rnrnIn 1970, Alfa Romeo updated their successful GTA racer to stay competitive within the crowded sub-2,000-cubic-centimeter category. Deemed the GTAm, Autodelta utilized the United States-market 1750 GT Veloce as its foundational platform. Crucially, the engine featured indirect fuel injection and was further upgraded with modified pistons to produce over 200 horsepower. Like the GTA, the interior was stripped down to the bare essentials, and in some cases, the doors were constructed out of aluminum for further weight savings. Although exact production numbers are unknown, approximately 40 examples are believed to have been built by Autodelta. The car was ultimately a force on the racetrack, and in 1971, touring car ace Toine Hezemans clinched the 1970 European Touring Car Championship behind the wheel of a 1750 GTAm. rnrnCompleted in May 1970, according to Alfa Romeo documentation on file, this car was delivered the following month to Brussels, Belgium. It is understood to have been raced by Alfa Romeo Benelux upon its delivery. The car was subsequently owned by West German driver Franz Abraham of Rosenheim, and the accompanying original ONS-Wagenpass details its racing exploits between 1973 and 1975. The 1750 GTAm would eventually reside within Switzerland by the mid-1980s before being sold to the current owner in 1988. A collection of Polaroids on file shows the GTAm to have been in tidy and complete condition at the time of purchase. rnrnToday, the car presents in equally good order thanks to the diligence of its present long-term owner. As shown in several documents on file, the engine received some tuning and additional work around 2015, and the accompanying dyno graph reveals a healthy amount of power was extracted from the little four-cylinder; this correct 1,750-cubic-centimeter fuel-injected twin-plug engine is said by the consignor to have accrued no racing hours following its refurbishment. rn rnIf one were to distill the pure essence of Alfa Romeo into one vehicle, the 1750 GTAm with its handsome, purposeful saloon body, and barking, highly tuned engine would be the result. The car on offer is undoubtedly an object of desire for any enthusiast of the famed Milanese manufacturer and will certainly be a highlight of any collection-and a credible contender on the track to boot.To view this car and others currently consigned to this auction, please visit the RM Sotheby's website.
