We had an extended trial run on one of these cars. It had a four seater fabric body and the complete car we were told weighed 47 cwt. The engine is 3½"x 5" which gives a displacement of 6300 c.c. This is another case of a car whose engine has recently had the bore increased, as two years ago the Lincoln displacement was 5,870 c.c. with a bore of 3.35". The gear ratio is very low, being 4.6 on top with tyres corresponding to those used on the Phantom. Having a final drive 23.6% lower than the S.S. its displacement / mile is 2% greater than the S.S. Its performance as a car is very good. Its acceleration is such that it climbed Netherall Gardens from 10 m.p.h. on top gear. It holds the road well. Its brakes are quite effective which is surprising since no servo motor is fitted. The clutch is light and sweet in operation. The steering has little self centering but gives quite good selectivity and control at all speeds. There are no signs of wobbles at any speeds. "Houdailles" are fitted all round. These make the car controlable, much more so than any ordinary American car, but produce harsh riding in the rear seats. The car appears to have | ||
