Maserati Tipo V4: 90 years ago Mario Umberto Borzacchini's Cremona Record
On 28 September 1929, Mario Umberto “Baconìn” Borzacchini, at the wheel of a Maserati Tipo V4, set the world land speed record for the flying 10 kilometres.
The car had made its race debut on 15 September, driven by Alfieri Maserati in the Monza Grand Prix, finishing the race in sixth place. Two weeks later, before the race at the Circuito di Cremona, the “Giornata dei record”, a time trial on the flying 10 kilometres, was organised. The race was held on the old state (now provincial) highway no. 10-Padania Inferiore, which runs in a straight line East-North-East out of the city of Cremona for approximately 17 km.
The international rules required the course to be completed twice, once in each direction. The average of the times logged was approved for the purposes of the record.
Borzacchini covered the uphill leg in 2’25”20/100, with an average speed of 247.933 km/h. On the downhill leg he took two more seconds, logging 2’27”40/100, giving an average of 244.233 km/h. His overall average time was 2’26”30/100, equivalent to a speed of 246.069 km/h: world record for class C (from 3,000 to 5,000 cc).
The record was an outstanding achievement, celebrated in Bologna with a dinner hosted by the Automobile Club attended by the city's top officials, the drivers and Enzo Ferrari, who took advantage of this opportunity to persuade the two wealthy Emilia-region businessmen Alfredo Caniato and Mario Tadini to establish the racing team which was to bear his name.
