Woolf Barnato and the Legend of the Blue Train. The Blue Train Races were a series of record-breaking attempts between automobiles and trains in the late 1920s and early 1930s. It saw a number of motorists and their own or sponsored automobiles race against the Le Train Bleu, a train that ran between Calais and the French Riviera. http://en.wikipedia.org/wiki/Blue_Train_Races
The Hanomag "1,3 Liter", Germany 1939 This German company was producing cars as early as the 1920s but they struggled financially through that decade. In 1931, Hanomag had 25% of the small-car market in Germany, trailed by DKW (19%) and BMW (17%). The following year they gambled on concentrating on a single series–the 1.1 Liter (later re-named Garant). The gamble worked, and soon it was necessary to run the plant two-shifts to meet the demand.
Built by Augusto Monaco and Carlo Felice Trossi, the 1935 Monaco Trossi is a front engined beast designed to race in Grand Prix, but due to terrifying driving dynamics never did. The engine is an eight bank, 16-cylinder radial air-cooled 2-cycle, 3982cc engine with two Zoller superchargers. The whole shebang was good for 250 HP at 6000 rpm and powered the front wheels.
