b The Pierce-Arrow Car has a new engine T HE Dual Valve Engine retains for the Pierce Arrow Car all the advantages of the six-cylinder power plant, with so much additional power that the necessity of shifting gears is much reduced. The car will slow down to five miles an hour in traffic, mount any ordinary hills, speed up to seventy miles (if desired) without shifting from high gear. It offers more power, more speed, more comfort with less gasoline, without increased weight and less gear shifting. This new engine is the natural development of the constant aiming at greater comfort. Power is comfort-power and ease of its application. The Dual Valve Engine gives the Pierce-Arrow both.
