The Warwickshire company behind the Gibbs Aquada amphibious car has been honoured with the Sir Henry Royce Memorial Gold Medal for the pursuit of engineering excellence.
Gibbs Technologies, which has a base in Nuneaton, was recognised for developing technology for high speed amphibious (HSA) use.
The company's Aquada car, which can reach 100mph on land and faster than 30mph on water, has already broke the record for an English Channel crossing by amphibian craft.
Neil Jenkins, the company's managing director, gave the Institution of Incorporated Engineers Sir Henry Royce Memorial Lecture in London after being being presented with the medal.
It was the second major award for Mr Jenkins, and follows the Churchill Medal by the Society of Engineers.
Gibbs Technologies Limited (GTL), under Mr Jenkins' leadership, has been granted 60 patents covering its ground-breaking High Speed Amphibious Technology.
