The torque on this car is of course taken through the rear springs only. SMALL DOUBLE SIX DAIMLER - 3744 c.c. The car we tried was fitted with a coach built closed xxx body and we should estimate the total weight as about 36 cwts. The engine was certainly smooth with an absence of torque reaction. It had no perceptible periods on the gears. It was however singularly lacking in 'pep'. The low speed MEP. of this engine cannot be good. Personally, we much preferred the performance of the 25-85 which we previously tried. The springing of the car was good for town conditions but far too flexible for any speed work. We understand that Daimlers have been having continuous troubles with their rear axles since they increased their engine power. Their Agents seem to think that the Company is in a deplorable condition due to the multiplicity of models and lack of attention to the chassis as opposed to the engine. STUTZ - 4800 c.c. This car has a displacement/ton mile of between 8000/9000 litres so one expects a good performance. We tried a closed car. The top gear acceleration was quite good, the most pleasing feature being the instantaneous response to the accelerating pedal. The engine was not obtrusive though naturally not ultra smooth or silent. We could detect contd:- | ||
