Outback buyers choose between a revised, 170-hp version of Subaru's 2.5-liter horizontally opposed four-cylinder engine and a new version of Subaru's existing boxer six. The new six-cylinder is bored out from 3.0 to 3.6 liters and now runs on regular fuel. While the six is mated solely to a five-speed automatic transmission, the four can be mated either with a new-to-the-USA six-speed manual or to Subaru's brand-new CVT (continuously variable) automatic with paddle shifters. The Legacy GT sedan's turbocharged four is not offered here
