The Acura ARX-05 DPi has completed two days of successful testing this week at Road Atlanta, as Acura Motorsports and Team Penske continue to prepare for the car’s IMSA WeatherTech SportsCar Championship campaign in 2018.

Veteran Juan Pablo Montoya, one of two drivers already announced for the effort, was at the wheel of the ARX-05 throughout the two-day test. The outing was the first for the new prototype following an initial shakedown run last month at the Paul Ricard circuit in France, and follows its official unveiling at Monterey Car Week.

“Overall, it was a good test,” said Matthew Niles, senior engineer and project leader for Honda Performance Development.

“We were close to the area of total solar eclipse [on Monday], so we had to stop running for a bit as the sun was dimmed. We went on to complete all of our run plan, and feel we have a good base to build on going forward.”

This week’s initial run was the first of a series of tests, to be conducted at a variety of circuits, planned by Team Penske and Honda Performance Development, the racing arm for both Acura Motorsports and Honda Racing in North America.

The competitive debut of the Team Penske Acura prototypes is set take place at IMSA’s season-opening Rolex 24 in January, 2018.
