Bryan Bouffier and Juho Hanninen resumed testing with the brand new Hyundai i20 WRC last week, as the team ran at high altitude for the very first time.

The gravel test took place in the South of Spain and followed a three-day tarmac test in France earlier this month.

"For the last couple of months we've tested every two weeks on all kinds of conditions and surfaces to continue the collection of valuable feedback and data. After the Finland test [in the summer] though it was very important for us to take a short break back at the factory in order to review and evaluate the work done so far as the schedule will be even busier from now on," explained Hyundai Motorsport team principal Michel Nandan.

"The car used [in Spain and France this month] was the same specification to the one we used in Finland in August but it features a couple of new elements," Nandan continued.

"Altitude is one of the challenges we'll have to overcome next year in the FIA World Rally Championship especially in Mexico where the stages go up to 2500 metres," he added. "The performance of the car can be affected under these conditions so the aim on this test [in Spain] was to study the engine behaviour and monitor the impact on the engine power.

"We also took the opportunity to keep on working on gravel set-up solutions and do some good mileage with the car."

Hyundai's test programme will now continue unabated over the next months in the countdown to the 2014 WRC opener in Monte Carlo.
