Caterham Formula 1 Team launched its 2013 car on the first day of pre-season testing in Jerez and one addition to the car's striking new livery is McGregor, the Dutch fashion company that traces its roots back to New York in 1921.
The McGregor logo now appears on the CT03 and across all of the Caterham's F1 branding platforms.
Cyril Abiteboul, Caterham team principal said: "We are all very pleased to welcome McGregor into Caterham F1 Team. McGregor is not new to Formula One and if they have no doubt of the value that our sport can deliver to their brand, their expectations of the value their activation of this partnership will deliver will be just as high.
"Securing an Official Partnership with McGregor is a great testimonial for us, for all the hard work that we continue to do to build our platform on track and at the factory, to the benefit of the Caterham brand and all of our partners."
The pre-season testing began in Jerez on Tuesday.
