As the automobile industry enters the era of electrification, the number of new automobile manufacturers is also increasing. A large number of new companies are being born through lower barriers to entry, such as a relatively small number of parts and a simple vehicle structure compared to internal combustion engines.
Tesla is already showing tremendous corporate value by standing shoulder to shoulder with established automakers, and Lucid Motors, Livian, and the miraculously lasting Faraday Future are also jumping into the electric car competition based on their outstanding technology and design.
Croatia-based Limak is also one of these new electric car companies, and it is building hypercars that surpass them all at once, making full use of the strengths of electric powertrains in the supercar market, which was dominated by a few companies such as Ferrari, Porsche and Lamborghini.
In addition, Rimac is steadily expanding its influence in the electric vehicle market by supplying electric motors and batteries for Legera models to Konigseg and providing electrified drivetrains to other companies.
Established in 2009, Limac revealed its concept of Concept One in Frankfurt in 2011 and made their presence known in earnest. In 2016, Rimac succeeded in small-scale production of 8 Daehan tablets and entered the hypercar competition represented by Pagani and Konigseg.
Concept One, which was unveiled at the Frankfurt Motor Show, boasted a zero-back of 2.8 seconds and a top speed of 305 km/h, but Limak was proud to improve it to a zero-back of 2.6 seconds and a top speed of 355 km/h in the mass production model. This was a very encouraging development given the 1,850kg weight of an empty vehicle due to the battery inside the mass-production model.
Concept One was equipped with four electric motors on each wheel, and the battery was capable of delivering up to 1000kW of power. In addition, it was able to absorb up to 400kW of energy again during braking, and the AWD torque vectoring system’R-AWTV (Rimac All Wheel Torque Vectoring)’ enabled a more sophisticated and stable driving.
Thanks to this success, Limak unveiled its second hypercar, C Two, in 2018. The overall specifications of the C Two are 4750 mm long, 1986 mm wide, 1208 mm high, and 2745 mm wheelbase, with an empty vehicle weight of 1950 kg. Despite its two-ton bodywork, the C Two was able to reach 100 km/h in about 1.8 seconds with an electric motor delivering up to 1,914 horsepower and 234.6 kg.m of torque.
It also reached a top speed of 415 km/h and was able to drive up to 647 km with a lithium manganese nickel battery with a capacity of 120 kWh.
The official launch of C Two, which has shown such tremendous performance, is expected soon. Recently, Limak released a picture of C Two’s ventilation test, saying that the development for mass production was at the end.
Limak has made three different prototypes for the ventilation test, and based on this, said that it had completed the last ventilation test before launch. They also conducted thousands of CFD simulations prior to ventilation testing, and reported that virtual and real tests were able to improve aerodynamic performance by more than 34% compared to the initial model.
In addition, Limak explained that although it is an electric vehicle that generates less heat than an internal combustion engine and the cooling system is not complex, it has tested the thermal efficiency and cooling performance of the battery using 180 million detailed parts.
As mentioned above, Limac already possesses excellent technology enough to supply electric trains to various companies, but will achieve higher reliability through extreme battery testing.
Along with the cooling test, Rimac has already conducted the’ElectroMagnetic Compatibility (EMC)’, which measures electromagnetic waves emitted from various electronic components inside the vehicle in January of this year. C Two is equipped with a 120kWh large-capacity battery and four electric motors, so it emits a considerable level of electromagnetic waves. This is a test to see if these electromagnetic waves are harmless to the human body.
In this test, Rimac measured the amount of electromagnetic waves emitted by the drive train as well as the electromagnetic waves emitted by the operation of all electrically powered parts such as headlights, wipers and indoor air conditioners.
At the same time, tests were conducted to see how the vehicle was affected by exposure to electromagnetic waves between 20 MHz and 30 GHz. It is to test whether the deterioration of the electronic devices inside the vehicle is detected due to the influence of strong electromagnetic waves.
Limak struggled in many ways for better performance, including testing the entire vehicle as well as individual parts such as electric motors and batteries.
In this way, Limak has successfully attracted investments from Hyundai and Porsche in the past, in recognition of its outstanding technology and passion to create the best vehicles.
Limak’s founder and CEO, Mate Limak (Mate Rimac) announced that the release of C Two would be imminent, but did not disclose the exact date. I’m looking forward to seeing if Rimac can successfully release a new hypercar after a long period of development. Thank you.
