General assumptions of the project

There were several conceptual assumptions during the creation of the Yotoda prototype. One of them was to build a car based on the existing model of an off-road vehicle which had been positively verified by at least several years of use. It was no accident that Toyota had been chosen for this project. Undoubtedly, this make of car is associated with manufacturing the most durable and reliable off-road vehicles worldwide, having rich experience and raising the bar to the highest level from among the manufacturers of four-wheel drive off-road vehicles around the world. The decision to base our design on a particular car model allows us to purchase 99% of spare parts on the basis of the VIN. Owing to that, Yotoda vehicles can be used in all corners of the world and every motorcar mechanic will easily handle their servicing.

The next assumptions which we followed while constructing both the Yotoda prototype and the production model were to minimise the weight of the car ready for start and keep its centre of gravity as low as possible.

In fact, it is not the power of a car, but its power-to weight ratio that counts. It is always worth it to strive for low weight. Let us assume that we have two cars with identical power-to-weight ratio: then the lighter one will be faster anyway. Why? During acceleration, both vehicles will behave similarly, however during cornering the lighter vehicle will prove considerably faster. The weight of a Yotoda car ready for start in a rally, depending on the model, oscillates between 3,306 and 3,747 lb, including the full fuel tank.

Another assumption made by our team while constructing the Yotoda car was the safety of the vehicle users. That is why we constructed a roll cage based on the FIA technical regulations which specify both the material to be used and the cage design itself.

Owing to the adopted strategy, our team managed to implement very important assumptions which characterise Yotoda:
- reliable design
- easy vehicle servicing
- user safety
- low vehicle weight and very good power-to-weight ratio of the car.

Performance

The engines used in our vehicles, operating at around 198 hp, combined with the vehicle weight oscillating between 3,306 and 3,747 lb, and the centre of gravity located as low as possible, all ensure considerable advantage over heavier rally vehicles popular around the world. The acceleration from 0 to 62 mph for the model equipped with the 3.0 D4D Diesel engine amounts to 7.2 s.
