Duesenberg Model X

The Duesenberg Model X was a luxury car built by Duesenberg in Indianapolis in 1926 and 1927 as an improved version of the Model A. It kept the 260 cubic inch (4.3 litre) straight-eight engine with a single overhead camshaft, but with a new crankshaft, a revised valve train and timing, different pistons and all manifolds on the right side, which raised output from 88 to 100 horsepower and gave a top speed of about 100 miles per hour. It was supplied as a rolling chassis with hydraulic four-wheel brakes, and coachbuilders such as Locke and Company and McFarlan fitted custom bodies. Only 13 chassis were made, and around five finished cars are thought to survive. After E. L. Cord bought the company in 1926 attention turned to the larger Model J, which followed the X, and the Model X program was cut short.
