The Scalextric4Schools final competition will take place on Sunday June 24th at the RAF Museum, Cosford.
For the first time, this year's competition has drawn participants from schools outside of the UK to include two teams from St Petersburg, Russia.
The competition aims to inspire young students to consider design and engineering in high education and as careers. Over 500 schools take part annually, many incorporating the competition into curriculums.
PTC sponsors the challenge along with its UK partner, Root Solutions, and Hornby Hobbies.
Since this year's challenge was launched in October 2011, children aged 11 to 18 have been designing, manufacturing, testing and refining their slot cars. Ten teams will battle it out in the final.
They will be racing their cars on a landscaped Scalextric layout and presenting to a panel of judges on how they designed, manufacturered and tested their cars.
"I'm excited to see how the children have worked on their designs and what's finally been created," said Tom Malloy, industrial designer at Hornby Hobbies, who is part of the judging panel.
