The R&D office was opened at Warwick Enterprise Park, and it expects to hire 30 people by the end of the year.
The office will cooperate with the UK automobile industry and the company headquarters in Croatia.
Rimac went public with the news about the new office on the occasion of the British minister's visit to the company headquarters, which the British official described as inspiring.
The new office was opened near Warwick University near the city of Coventry.
Accompanying the visiting British minister was British Ambassador to Croatia Andrew Dalgleish.
Rimac said that the UK had first-class engineers in new technologies for vehicle electrification and future mobility, noting that in the years to come the UK office could significantly expand.
"Even though Croatia will always be our home, we have decided to take this opportunity and form a small team in the UK, where the automobile industry has a long history and a high level of expertise," he said.
His company currently employs almost 1,000 people and is continuing to rapidly expand.
Rimac Automobili has already cooperated closely with UK companies, having delivered technology for car brands such as Aston Martin and Jaguar.
Rimac Automobili is a supplier for many of the world's biggest car manufacturers like Hyundai, Porsche, Pininfarina, Koenigsegg and others.
The company said that it would soon present its super sports electric car C_Two in its final form. The serial production of the car will start soon and it will be limited to 150 units.
Hands told Hina that he was visiting Croatia to help maintain good trade relations with EU member-countries now that his country had left the Union, a decision which he had opposed.
Croatia is a like-minded country when it comes to the free market and is a good friend, said Hands, who earlier in the day met with PM Andrej Plenković's advisor Vladimir Drobnjak and who in the coming days is expected to meet with several government ministers, including the economy minister.
Ahead of Hands's the UK Embassy said visit that the UK was sending a clear message that it wants a close partnership with Croatia and excellent local companies, with emphasis on green technologies.
