Supposedly, no. AGR will drop their ALMS program to concentrate on their four IRL cars and fielding Marco in A1GP. At least, that's what everyone has been reporting over the last few months.
However, Murphy the Bear has been reporting on his blog that there's a fourth Acura that's probable for Sebring and questionable for the rest of the ALMS season. He doesn't say who the team is that might be fielding it, or even if it's LMP1 or LMP2. He's also said that the financial crisis going on right now may change Acura's whole program. So, who knows?
