In theory the Arctic Cat 6000 C-TEC2 motor will provide solid all-around performance, the type of performance that two-stroke riders expect. The engine revs easily. It seemed to have a good powerband, but we felt elevation worked against it as the midrange acceleration felt less than we would expect from the competition of Ski-Doo's 600 E-TEC and the Polaris Cleanfire 600. We are going to give the Cat motor a pass here as we expect that engine mapping and final tuning has always been aimed at sea level production and not at Rocky Mountain highs. If you look at the number of 6000 C-TEC2 powered sleds for 2014, you'll see just one, the El Tigre. It's a flatland sports model, which means sea level specifications.
