We are after better fuel economy. We can never compete with the American cars because we are so much heavier. In the tests in question it will be seen that our additional weight costs us almost 2 1/2 M.P.G. The Bentley confirms this. We ought to be able to improve 1 1/2 m.p.g. by better distribution and possibly suction ignition control. Tests are proceeding. Rm.{William Robotham - Chief Engineer} | ||
