Whippet 93A History


In January 1927, the first Whippet 6 was introduced.  However, unlike its 4 cylinder companion, it was not a totally new car, but rather a refinement of the 1925 - 1926 Model 93 Overland 6.  The biggest difference in terms of specification was that the 112 ¾ inch wheelbase of the 93 had been shortened by 3 ½ inches to make the 93A measurement 109 ¼ inches.  Front springs were 34 ½ in long and rear springs were 51 ¾ in long (just 1 ½ in and 2 ¾ in longer than Whippet 96).  Contemporary advertising claimed you could park this new car in only 15 feet of curb space.
The same 3 in x 4 in side valve engine (21.6 RAC Horsepower) with gear driven camshaft and 3 bearing crankshaft was used, but changes to manifolding and carburetion gave 40 bhp @ 2800 rpm instead of the previous 38 @ 2800 rpm.  Firing order was 1-5-3-6-2-4 and the oil pressure was quoted as being in the 10 to 20 lbs/sq in range (compared to Whippet 96 figure of 15 to 30 lbs/sq in).  Autolite ignition was used and the IG 1323 distributor cap (Lorimier AU76) fitted on Whippet 93A was also used by Nash (1925-28) and Hupmobile (1926-34).  The Whippet 98, 98A and Willys 98B used a different distributor and the cap is not interchangeable with Whippet 93A.

Transmission was the conventional 3 forward speeds through a Borg and Beck clutch - just like the Whippet 96, but the final drive ratio was higher at 5.11 to 1.  Cooling capacity was 3 1/8 gallons, 3/8 gallons more than Whippet 96.  Four wheel brakes - 3 shoe front internal and 2 shoe rear external with a total lining area of 220 sq inches - were standard, making it the lowest priced six with 4 wheel brakes.
Standard equipment also included cowl ventilator on closed models along with automatic windshield wiper and snubbers on the front springs.  Both the Sedan and Landau received a dome light, but an ash receiver and vanity case were exclusive to the Landau.
The automatic wiper and the external rear brake configuration were adopted later by the Whippet 96 as part of the many changes during production.  Externally the Model 93A looked very similar to the Whippet 96, but with a longer hood and thus more hood louvres.

Beginning with car serial no. 96758, a longer type rear spring shackle assembly 349758 superseded 342015 shackle and 342016 bolt to prevent the shackle reversing on rebound.  The last few thousand Whippet 93As were fitted with Tryon spring shackles.
The Whippet 93A was also manufactured with a 6 cylinder sleeve valve engine - but not as a Whippet, instead it was called the Falcon Knight.  Except for the engine and 3 shoe internal brakes all round, the Falcon Knight chassis matches the Whippet 93A.
The Whippet 93A was superseded by the Whippet 98 announced April 15th, 1928.
