A Mini 4WD race car is a 1:32 scale kit featuring four-wheel drive powered by an electric motor using a pair of AA batteries. A single electric motor turns both axles. These kits snap and screw together without the need for glue. [2]
In a direct drive simracing steering wheel system, the wheelbase and the wheel rim are typically separate, so that is possible to switch between rims according to the use case, for instance formula wheelrims, GT wheelrims, oval racing or truck wheel rims. The base and the rim are typically connected through a quick release system.
4D Inc is a US-based subsidiary of 4D SAS and publisher of 4D.It was established in 1984 and initially led by Guy Kawasaki. [citation needed] 4D is the developer and publisher of 4D (or 4th Dimension). 4D was founded in 1984 when development began for Silver Surfer (early code-name for 4D) and had its initial product release in 1987 [1] [2] [3] with its own programming language.
Some cars are designed with a rear wheel drive powertrain where the power is sent to the rear wheels. This design is cheaper than the M4 design because of the limited parts required to make the system function. Manufacturers use a unique layout to balance the weight distributed between the front and rear axles.
Concept (top view): In a vehicle, motors M1 through M4 drive respective wheels independently, possibly through respective gear arrangements. Individual-wheel drive (IWD) is an automobile design in which the vehicle has an all-wheel drive powertrain that consists of multiple independent traction motors each supplying torque to a single drive wheel.

In automotive design, an F4, or front-engine, four-wheel drive (4WD) layout places the internal combustion engine at the front of the vehicle and drives all four roadwheels. This layout is typically chosen for better control on many surfaces, and is an important part of rally racing, as well as off-road driving.
The Symmetrical All-Wheel Drive (also known as Symmetrical AWD or SAWD) is a full-time four-wheel drive system developed by the Japanese automobile manufacturer Subaru. The system consists of a longitudinally mounted boxer engine coupled to a symmetrical drivetrain with equal length half- axles .
The use of separate motors for the front and rear drive wheels eliminates the need of a drive shaft that is ubiquitous in four-wheel drive ICE vehicles, freeing up space for bigger battery modules, which are commonly mounted on the chassis floor between the axles. [1]
