This past weekend, the American Le Mans Series headed north of the border for its annual outing at Mosport northeast of Toronto. This is the first Canadian race since the Michelin Green X Challenge debuted last year at the Petit Le Mans. As has been the case several times before this season, the prototype and GT classes were won by Acura and Corvette. This time around, the same Highcroft racing Acura ARX-02a that took overall victory on the track also won the efficiency challenge.
The cellulosic E85-fueled Corvette C6.R had the best combination well-to-wheel emissions and the best tank-to-wheel efficiency of any of the GT cars. This time it wasn't the race-winning Johnny O'Connell / Jan Magnussen car that won, but the third place #4 car of Oliver Gavin and Olivier Beretta . Next up is the 2009 edition of the Petit Le Mans in three weeks.
