during a tour of automotive research facility French in 1946, he earned a reporter Paris Autocar, along with WF Bradley, two rare BMW image in which was captured via the research base Stuttgart at the end of World war 2.

the first will be easy to identify – along with 328 berlinetta via tourism, which was driven to the first along with only BMW victory from the Mille Miglia in 1940 – although the item was the second rather than curious. Action Lean senior Wunibald cam, K4 was an experimental car built to investigate the “simplification, high academic road holding along with the economy from the process,” from the words of Bradley.

devoid of solid detail, a man Autocar gleaned in his best French engineers. “The Centeng will be a very interesting along with surprising, surprising advantage of being on the almost vertical rear panel,” he wrote. “Completely flat, will be set headlights to the surface under the influence from the wings, the windscreen rounded in side panels, steering wheels attached.”

will be certainly distinctive, widespread on the 335 luxury product featuring “suicide doors” Front, which stops off B- pillars, as did the traditional rear doors.


along with K4 drag coefficient of 0.196 at a time when contemporary saloons around 0.5Cd, although experimenting with aerodynamics without the use of computational fluid dynamics research means in which the case of trial along with error.

in order to make a stable fast car, there have been experiments with fins. “Fin single, with or without slots, has little impact on the stability, along with may even be harmful,” Bradley wrote. “To be of any use, the item must be fin excessive dimensions. Two fins without slots are not the best. They have a tendency to drift the auto on the straight path, along with which contain the effect of raising the rear.

” along with are getting the best results through a pair of flippers specified period of time, definitely the item consists of fin along with rudder. The implementation of This kind of system in a glass. “


along with K4 3.5-liter six-cylinder engine, producing 88bhp. The processing engine that has a carburettor double”, uses part of the normal operation of the some other part comes into action from the last movement of the throttle pedal . “

gearbox four-speed driving on the rear wheels along with reinforced through the planetary dimensions.” road tests by the French revealed fascinating dimensions of advantages, “noted Bradley.

Although the engineers tested roads which includes hills, dense regions based traffic, along with K4 will be still the economy returned to fuel impressive consumption. at 77mph, along with 1950 rpm, has been measured at 24.4mpg. at 35mph along with 900 rpm improved upon to 32mpg. “the item was possible to get the results certainly much better German autobahnen “mulled Bradley.

due to poor tire condition along with K4, along with they were not able to test car to a top speed of 0 mph engineers. the auto was also automatic regulate tire pressure to amend the rolling resistance, despite the fact in which some parts of the system are missing, along with they were not able to verify the effectiveness of engineers.

K4 fate will be unclear, although the item will be likely in which the item was dismantled by the French engineers curious to know all the secrets. The philosophy behind the auto remains important for BMW ever, with 2009 in view the concept of effective dynamic considered the modern equivalent for K4 along with in turn inspiring I8 .
