Rimac Automobili

 

Rimac Automobili is a Croatian company that develops and produces high-performance electric vehicles, drivetrain and battery systems. Rimac Automobili’s first model, the Concept One, is known as the world’s fastest production electric vehicle. While Rimac sells high-performance vehicles under their own brand, the company develops and produces drivetrain systems and full vehicles for other companies. The Applus IDIADA Volar-E is an example of the services Rimac Automobili offers and executes for other companies.

History
The groundwork for the company began in 2007 as a garage-housed hobby of founder, Mate Rimac. He converted his BMW E30 to incorporate an electric powertrain and subsequently gained attention from press and investors. Much of the early financing came from selling patents and from family money. The company itself formed in 2009 and rented facilities in Sveta Nedelja, near Zagreb, Croatia. The e-M3 was Rimac Automobili’s first test mule. The founder and CEO Mate Rimac started to convert this car when he was only 19 years old: “I owned an old BMW E30 (MY 1984) which I used for drift and circuit races. At one of these races, the gas engine blew up. Then I decided to try building an EV. After one year or so the car was able to drive but I was not satisfied with the result. It was heavy, not very powerful and the range was very limited. I started to gather a team of experts to develop our own components since I believed that the electric propulsion can give much more compared to what was available on the market. At that time, I already had a very clear vision of my ultimate goal. Today, hard work is making my dream come true.”

Concept One
With a curb weight of 1650 kg, and 1088 HP, the Concept One can reach 100 km/h from a standstill in 2.8 seconds and continue to accelerate to the limit of 305 km/h. 92 kWh of energy in the Battery modules delivers enough juice for up to 600 km of range. The company plans an initial run of 88 vehicles mainly targeted at the European market. Almost all of the materials are produced in-house; no critical components are off-the-shelf. The current design team includes former designers from Pininfarina and Magna Steyr. The exterior was designed by the young Croatian designer Adrian Mudri.

A very important chapter in the Rimac Automobili history was the Frankfurt Motor Show. They have released very few details about the project prior to the Auto Show – they have tried to keep as much as possible secret. At the unveiling of the car, hundreds of journalists from the show lined up in front of their stand. Many employees of big car manufacturers visited their stand as well. BMW, Tesla, Audi, Fisker – all of them where very surprised what an unknown private start-up company has established, and the car was the star of the show, since the previously unknown company managed to build an electric supercar with a technology that surpassed even the most competitive and financed car manufacturers. They had displayed the battery module and propulsion system on the stand which was the most interesting sight for engineers from other car manufacturers. They looked at every detail because Rimac Automobili battery can store 92 kWh of energy. The secret is how to package such a huge and heavy battery in a sportscar and still have great acceleration (0-60 mph in only 2.8 seconds).

The Concept One is designed to be the best electric supercar, not a supercar with electric motors. The independent drive system and low mounted batteries are specially designed for the driver to adjust. The whole car is developed around the powertrain and battery-pack. Gear changes or clutches are not needed and the reaction time is instant. The batteries can be located in the floor, together with all the other heavy propulsion components in order to achieve a low center of gravity. Thanks to the All Wheel Torque Vectoring System the driver can choose how he wants the car to behave – he can choose between over-steering, under-steering or a neutral handling, adjust the KERS (Kinetic Energy Recovery System) intensity and a whole range of other driving parameters. Each wheel is powered by a separate 12,000 rpm, 250 kW liquid-cooled permanent magnet motor for an overall 1088 HP and 1600 Nm of torque. The vehicle achieves the speed range from 0 to 100 km/h in 2.8 seconds with a limited maximum speed of 305 km/h. The batteries are also designed to be economic – one charge can operate the car for around 600 km (320 miles), and needs to recharge for only 30 min (with an 200 kW power supply station).

Besides its high-tech powertrain and batteries, there is also a high-end interior technology. The infotainment keeps the driver informed about various vehicle systems, the head-up display allows him to keep focused on the road, ventilated and heated seats as well as the electric adjustable steering column are assuring a comfortable driving experience.
