Rimac Automobili is a Croatian car manufacturer that develops and produces high-performance electric cars, drivetrain and battery systems, headquartered in Sveta Nedelja, Croatia. Rimac Automobili's first model, the Concept One, is known as the world's fastest production electric vehicle.[3] 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 [4] of the services Rimac Automobili offers and executes for other companies.

History

Early work of Mate Rimac

The groundwork for the company began in 2007 as a garage-housed hobby of founder, Mate Rimac, Bosnian Croat from Livno, Bosnia and Herzegovina.[5][6] He converted his BMW E30 to incorporate an electric powertrain and subsequently gained attention from the press and investors.[6] Much of the early financing came from angel investors and selling patents.[6] The company itself was formed in 2009[7] and rented facilities in Sveta Nedelja, near Zagreb, Croatia.[6] 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.”[8]

Green Monster

The prototype BMW E30 is called the "Green Monster" by the designers. With a 0-62 mph in 3.3 seconds mark, it is the fastest accelerating electric vehicle in Category A, Group VIII, and Class 3 sections (over 1000 kg). The “green monster” develops 600 horsepower, 900 Nm of torque, reaches 100 km/h from standstill in 3.3 sec and a top speed of 280 km/h. Five development evolutions have pushed the e-M3 to become the officially fastest accelerating electric vehicle according to strict FIA rules.

The original BMW has now gone through five stages of reinvention and, says Rimac, "got faster, lighter and more reliable each time". When he realised how little of the original car remained, he decided to build a new car from scratch.[9]

Concept One

With a curb weight of 1850 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 planned an initial run of 88 vehicles mainly targeted at the European market.[6][10] As of October 2014, eight cars had been manufactured and sold which was the entire production.[11] Almost all of the materials are produced in-house; no critical components are off-the-shelf.[6][12] The current design team includes former designers from Pininfarina[6] and Magna Steyr.[12] The exterior was designed by the young Croatian designer Adrian Mudri.[13]

A very important chapter in the Rimac Automobili history was the Frankfurt Motor Show. They had released very few details about the project prior to the Motor Show and 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, including many employees of big car manufacturers, such as BMW, Tesla, Audi and Fisker. They 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 the Rimac Automobili battery can store 92 kWh of energy. The secret was 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 510 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.[14]

Concept S

The Concept S is a lighter, more powerful and more aerodynamic, track-oriented update of the Concept One. The electric motors can produce 1384 bhp, that means the Concept S can accelerate from 0–100 km/h in just 2.5 seconds and reach a top speed of 365 km/h.[15]

At the 2017 Geneva Motor Show the company announced the establishment of official dealerships of its brand in Europe, North America and the Middle East, with dealers Manhattan Motorcars, PACE Germany and Al Zarooni Group.[2]

Component manufacturing

Rimac is in charge for producing KERS hybrid battery systems for Aston Martin's all-new hyper car, the Valkyrie. Rimac also produces battery systems for Koenigsegg, specifically for Koenigsegg Regera.

It is also involved in the production of drivetrain and other components for race car drivers, such as Nobuhiro Tajima, with whom it debuted with the joint all-electric car "Tajima Rimac E-Runner Concept_One" at the 2015 Pikes Peak International Hill Climb. It finished the race second, ahead of all internal combustion engine cars.[16][17]
