New input case for you: Question: What manufacturer was Teddy Tetzlaff driving for in the 1914 Indianapolis 500? Passage:There were 45 entrants for the race, but only the quickest 30 drivers during the elimination trials would qualify for the race. The first day of trials was completed on the Monday before the race, 25 May. Caleb Bragg set the fastest official time on the first day, recording 1:36.8, though it was reckoned that Howdy Wilcox went quicker, but his time was not officially recorded. Ralph DePalma, a crowd favourite, struggled in his Mercedes and could only manage a quickest time of 1:47.4, slower than the 1:45 that it was predicted drivers would have to beat in order to qualify. Only fifteen of the drivers ran on the first day, and they continued with two session on the Tuesday. On the second day, three drivers set record times around the Speedway: first the 1912 winner, Joe Dawson, set an unofficial lap time of 1:34.8. Later in the day Teddy Tetzlaff completed a lap in 1:33.4, while Jules Goux finished the day as the fastest driver, with a time of 1:31.7. Tetzlaff's lap was completed in a Maxwell which was fuelled with a 50:50 mix of gasoline and kerosene; the other Maxwell, driven by Billy Carlson, set a time of 1:36.6 fuelled by a combination of kerosene and lucubrating oil, with no gasoline. Ray Harroun, who had won the inaugural Indianapolis 500 in 1911, designed the Maxwell car, and was given $10,000 () by the company's president as a reward for the cars qualifying with sub-1:37 times.
