If the quality is uniform, there is no difference before and after.

A few tanks adopt the layout of rear and front drive, such as Panther Tank, M3 Lee Tank and M4 Sherman.
It has always been an extremely rare driving layout in automobile history, and only a few prototypes and concept cars are used, such as "Howie-Wiley machine gun rack" of 1937 (nicknamed "dumper") and 1933' s Dymaxion car of BuckminsterFuller. Thanks to the rear wheel steering and the Gregory of 1947, it can
As the patent application of MichaelBasnett, the inventor and engineer of RoverGroup(GB), proves, people are interested in developing the use concept of future cars. He proposed the front drive shaft design and the flat engine structure at the rear.
According to this patent, the layout design is advantageous in terms of collision performance, allowing greater modeling freedom by increasing the front fold area, enhancing ride performance by reducing noise, vibration and unevenness, and providing improved handling, braking and rolling characteristics at a reduced center of gravity. Its main disadvantage is that there is no weight on the driving wheel, especially when the weight is transferred to the rear and the acceleration is large.
1932, HarleighHolmes, the chief designer of ColemanMotors in lyttleton, Colorado, designed and manufactured a prototype called MaroonCar, which was driven by a rear V-8 engine. Only one car was produced and never put into production.
