Some of you might remember Rimac Concept One – fast as hell vehicle that has incredible power output – 1088HP–and, probably, the best in the world torque vectoring system –all wheel torque vectoring results in incredible 1600 Nm from 0 to 6500 rpm.

Cool, isn’t it?

Even Tesla does worth, but we’re in here not to accolade the company.

The thing is that the company decided to reveal the unique patented technology to the public and decided to do it absolutely for free.

What for?

Well, let’s say Mate Rimac isn’t a greedy person and enjoys sharing with people – truth to be told, that’s not something we believe in. Our version is that Rimac Automobili has something so much better to use.

Hence, unveiling of the ‘old technologies’ isn’t something that can affect the image of the company.

Plus, it will increase the reputation of the company and will attract more potential investors and buyers.

However, it’s only our assumption and we don’t know if it’s true, but whatever version is true, let’s be happy about the fact that this technology was unveiled to us.

Let’s learn more.

Rimac’s all wheel torque vectoring

One of the many features that make the Concept One unique and define its essence is the Rimac All Wheel Torque Vectoring System (RAWTV).

The Rimac All Wheel Torque Vectoring system uses the maximum traction of each tire and gives the driver the possibility to adjust the driving behavior exactly to his or her preferences thus giving it superior driving characteristics.

This system precisely controls the torque of each motor 100 times per second. By utilizing the data from various precise sensors placed throughout the car and advanced control algorithms, it can use the maximum grip of each tire, thus providing superior dynamic characteristics.

Torque vectoring is electronic control of motors (four in the case of the Rimac) that enables to automatically adjust torque (up to 100 times per second) for each wheel independently, depending on the situation: speed, acceleration, traction, steering angle, and more.

It can not only change the torque up or down, but manage to accelerate one wheel while at the same time slowing the other.

More about RAWTV

RAWTV has various modes that give the car multiple characters, depending on the driver’s preferences and abilities.

In a way of example, the driver can choose an “oversteer mode” where the system helps skilled drivers to slide through corners. RAWTV not only changes the character of the car under acceleration and braking but also acts as a dynamic stability control system.

In comparison with the conventional systems where hydraulic brakes are used to stabilize the vehicle, the RAWTV takes advantage of the use of electric motors. Changing the torque more than a 100 times per second on each wheel, RAWTV covers the functionalities of traditional ABS and ESP systems faster and more efficient than ever before while delivering a whole suite of new functionalities and possibilities. Combining high safety levels with superior performance, RAWTV brings kind of a new driving experience.

With 1088 HP and 1600 Nm of torque the Concept One accelerates from 0-100 km/h in 2,8 seconds and reaches the limited top speed of 202mph (325 km/h). Thanks to the highly sophisticated liquid cooled battery system that can deliver more than 800kW of power, it can reach up to 330 km on a single charge.

Where is this system used?

5841.jpgRimac All Wheel Torque Vectoring was developed for the Concept One, but this system was also implemented in the Tajima Rimac e-Runner, a racing car that Rimac Automobili developed for Monster Sport

Nobuhiro Monster Tajima completed the Pikes Peak International Hill Climb race in the Tajima Rimac E-Runner finishing the race in front of all race cars with internal combustion engines. This was the ultimate proof of RAWTV’s efficiency and superior characteristics.

Will we see more cool things from Rimac?

As of now, Rimac Automobili is working under the new vehicle, so the answer is yes.

We don’t know absolutely anything about the new vehicle except the fact that it’ll be more powerful than Concept One and E-runner (racing vehicle), but even this tiny fact puts a smile on our faces – just try to imagine 3,000 HP vehicle.

Jees, I can only imagine what can happen to guts because of so much juice.

Anyway, we’ll learn it in a year or so, so let’s wish Rimac good luck and wait more range-topper from ambitious Croatian company.
