Backhoe loader of the backhoe could cause the vehicle to tip, most backhoe loaders use hydraulic outriggers or stabilizers at the rear when digging and lower the loader bucket for additional stability. This means that the bucket must be raised and the outriggers retracted when the vehicle needs to change positions, reducing efficiency. For this reason many companies offer miniature tracked excavators, which sacrifice the loader function and ability to be driven from site to site, for increased digging efficiency. Their relatively small frame and precise control make backhoe-loaders very useful and common in urban engineering projects such as construction and repairs
Rear-engine design ease of manufacture: A rear-engine, rear-wheel drive vehicle is prone to oversteer, which allows for tighter turner radius than that of a neutral or understeer condition of a vehicle, however this causes vehicle instability. For this reason, rear-engine design has been abandoned as a design option for regular passenger cars, but still maintains a viability for race applications. Although this layout was once popular, it was mainly found in small, inexpensive cars and light commercial vehicles. Most car makers have abandoned the rear-engined layout apart from Porsche who has gradually developed their design with improvements to the suspension and chassis
