Following the success of their 1600cc Crosslé 12F in Formula B in the US, Crosslé built a 5-litre car for Formula A at the end of 1968, the Crosslé 15F. Two raced in the US but did not enjoy any great success. A third 15F raced for some years in the British F5000 series.

Although listed as a 1968 design, the 15F first appeared at the end of that year and was intended for competition in 1969. The first two cars to leave the factory went to the US in October 1968, one for US Crosslé dealer Roger Barr and one for Ralph Loesser. They would race in the SCCA’s Northeast Division, where the 12F and 14F Formula B cars had proved popular, and where the Area 1 Championship was proving to be a popular new layer in between SCCA Nationals and more minor club events. Unfortunately, there was relatively little coverage of the Area 1 Championship, except in the New England Region “Pit Talk” publication, so we have little knowledge of how the 15Fs performed. Meanwhile a third car was also in the process of construction in October 1968 and was due to go to the US, but stayed in the UK and eventually appeared in the 1970 British F5000 series for Fred Saunders who used a Rover V8 engine.

Tim Osborne, owner of the Barr car and now also the Stanton car, is painstakingly constructing the history of all three cars, and OldRacingCars.com is delighted to be able to publish the results of his work. All and any help would be gratefully received. Please e-mail Allen at allen@oldracingcars.com or Tim at tim@zentekno.com if you can add anything.

Built in 1969 but not delivered and not then used until 1970 season. Fred Saunders: raced in UK 1970-1971 - Brian Leonard April 1972: appeared at Oulton Park 29 May (DNS) and Mallory Park 18 Jun 1972 (retired). To Richard Evans (Haverfordwest, Pembrokeshire) hill climbs late 1972 (e.g. Pontypool Sep 1972, Pontypool late April 1973 and Gower in mid-Oct 1973). Presumably the F5000 Crossle advertised by Bill Morris (Dale, Pembrokeshire) May 1975. Then entered by R.S.G. Blake at Bouley Bay 24 Jul 1975 as a 3.5-litre Buick-engined 15F and advertised by Bob Blake (Jersey) in April 1976 mentioning that it was "ex-Saunders" and then had "Chevron bodywork". Next seen when advertised from Birtsmorton (Worcestershire) May 1978 still with the Chevron body. Unknown until purchased from Ian Giles by Simon Brien (N. Ireland) who sold it on to Brian Cocks. Cocks had the car restored at the Crosslé factory in 1988 and fitted a Chevy engine instead of the original Rover V8. Raced by Cocks in HSCC Pre '71 Championship events, winning its class in 1989. Advertised by Cocks in February 1990 and sold to Frank Nowak some time in the early/mid 1990s and used in historic racing. Nowak still had it in 2001. Later to Stephan Collisi (Germany) and used in historic racing in 2004. Collisi retained the car until September 2012 when he reported on his website that "the 15F has been sold and went on to Austria to be used in the Histocup series". As of September 2015, the car has not featured in any Histo Cup Austria events.

A note on chassis number identification

Paul Sheldon's Formula 1 Register Fact Book: Formula 5000 1968-1971 identifies the chassis number of the Fred Saunders car as 15F-70-04. Tim Osbourne's first car carries Serial Number C15F6839 and his second, acquired in 2004, carries C15F6840. According to the race-cars.com web site, the ex-Saunders car carries Serial Number C15F6942. The chassis numbers quoted above have had dashes added purely for the purpose of improving legibility.
