Alpine continued the development of the A424 with a fourth test session, the first in endurance format at Motorland Aragón, an interesting circuit for its straight where top speeds are comparable to those of Le Mans.
The objective - ambitious for a first - was to log 5,400 km in 30 hours.
Although not quite reached, the results were largely positive, with 5,027 km covered.
After the first eight hours with no problems other than a puncture, turbo issues, oil and water leaks as well as an electrical problem briefly interrupted the A424's fine progress as it completed the 30 hours.
In addition to assessing the car's reliability, the team continued to work on the general setup, to run in reprensentative race conditions and to improve its understanding of the Michelin tyres, in terms of getting up to speed on cold tracks and multiple stints management.
At the same time, IMSA official tests took place at the Windshear wind tunnel in North Carolina with a second A424 as the first phase of the homologation process.
