DTM - The Deutsche Tourenwagen Masters

DTM technical regulations for the 2017 season were revised in key areas.  The engine power of the new vehicles was increased and at the same time, the aerodynamics were trimmed. The latest generation of DTM cars is more challenging to drive.  All vehicles are rear-mounted and have a 4-disc CFK clutch and a sequential 6-speed gearbox.

AERODYNAMICS

All DTM vehicles are equipped with a single tailgate: a Monowing with laminated Gurney. The inclination is adjustable from 10 to 20 ° (Norisring 5 to 20 °)  There are also special front and rear diffusers, a 30 mm high skid block underfloor as well as two permitted areas (one per side) on the front of the vehicle for flaps.

DRS

The Drag Reduction System (DRS) is a folding rear wing that allows for a higher top speed for a short time, thus making it easier to overtake.  The system is triggered by a button on the steering wheel.  The tailgate returns to its initial position when the driver goes off the throttle or a certain centrifugal force value is exceeded.  This is to prevent the vehicle from becoming unstable due to the lower contact pressure. In the season 2016, the use is limited.

ENGINE

In DTM, the 4-liter V8 engines from Audi-RS 5, BMW-M4 and Mercedes-AMG has more than 500 hp in 2017, with a cylinder bank angle of 90 degrees a maximum of four liters of displacement and a maximum of four valves per cylinder are permitted.  The intake system must be equipped with two air flow restrictors with a maximum diameter of 28 mm each. There is only one spare engine per manufacturer per season. 

TRANSMISSION 

In the DTM, only a single differential gear unit is approved which is used by all manufacturers.

SUSPENSION

The DTM vehicles have independent front and rear suspension and a double crossbar suspension.  The gas pressure shock absorbers are adjustable.

How's this for a Monday morning commute.

Witness it!

First some History from Wikipedia:

 1877 - French inventor Charles-Émile Reynaud improved on the Zoetrope idea by placing mirrors at the center of the drum. He called his invention the Praxinoscope.  Reynaud developed other versions of the Praxinoscope, too, including a Praxinoscope Theatre (where the device was enclosed in a viewing box) and also the Projecting Praxinoscope. Eventually, he created the "Theatre Optique", a large machine based on the Praxinoscope, but was able to project longer animated strips.

 In the USA, the McLoughlin Bros from New York released in 1879 a simplified (and unauthorized) copy of Reynaud's invention under the name "Whirligig of Life".

1878 - Railroad tycoon Leland Stanford hired British photographer Eadweard Muybridge to settle a bet on whether a galloping horse ever had all four of its feet off the ground.  Muybridge successfully photographed a horse in fast motion using a series of 12 cameras controlled by trip wires.  Muybridge's photos showed the horse with all four feet off the ground.  Muybridge went on a lecture tour showing his photographs on a moving-image device he called the zoopraxiscope. Muybridge's experiments inspired French scientist Étienne-Jules Marey to invent equipment for recording and analyzing animal and human movement.  Marey called his invention the chronophotographic camera, which was able to take multiple images superimposed on top of one another.

1879 - American George Eastman invents the emulsion-coating machine which enables the mass-production of photographic dry plates.

Today we have a thousand frames a second to witness a moment in time, slow motion.  Now for whatever reason that brings you to the track just like Muybridge we get to see the true force and abuse man and machine undergo during race day.  Like the horse, there is times a race machine does not have all four on the ground and the real prize here needs to go out to the engineers of these machines.
