A ‘hypercar’ built by Oxford-based Drayson Racing Technologies (DRT) has broken the electric land speed record that has stood since 1974. The Lola Drayson B12/69 EV reached a top speed of 204.2 MPH on the 1.86-mile runway at RAF Elvington in Yorkshire, beating the previous record by 40 MPH. Lola Drayson B12/69 EV shell pictuire

Desktop Engineering’s (DTE) role in the evolution of this car was in the engineering design process. DTE is an accredited business partner of Dassault Systèmes, a world leader in 3D software design technology, so were best positioned to provide counsel and training on what would be the most appropriate software solution. After fully understanding the complexity of the design requirements, DTE recommended the collaborative capabilities of CATIA PLM Express to DRT.

Graham Moore, chief architect at Drayson Racing Technologies, said: “Collaboration was critical to the success of this project and CATIA PLM Express certainly provided us with this. The functionality within the package enabled us to reduce development time and respond more quickly to any design modifications. Overall, it reduced the number of man hours we could have invested.”

 Lola Drayson B12/69 EV teamOn the record-breaking feat, Eric Schmidt, co-founder of Google, said: “We figure that in a number of decades all cars will be electric and in order to do that there have to be challenges. You have to have the best technology and learn from innovation and that’s something the British are very good at.”

This project was the first time that anyone had designed an electric drivetrain comprising stressed chassis members. The electric drivetrain needed to be capable of supporting the entire chassis loads endured when driving flat-out on the track including those expected during crashes. This was no easy task but extensive use of CATIA PLM Express and Finite Element Analysis (FEA) allowed this to be done in parallel with the packaging and cooling system work to enable quick iteration through numerous options in very short periods of time. The unique and powerful specification-driven modelling approach of CATIA promotes efficient concurrent engineering between styling and mechanical shape design, while ultra-fast functional modelling fosters productivity and flexibility.

Designed to the highest standards of quality and safety, the Lola Drayson B12/69 EV is being used to develop drivetrain technologies and systems to be used in a wide variety of future projects from road to race. It truly demonstrates the philosophy of using the racing track as a laboratory for the development of next generation electric car technologies.
