About Subaru Legacy

A 2.5-liter flat-four FB25 and a 3.6-liter flat-six EZ36D are carried over from the fifth-generation model. Output is slightly increased on the four-cylinder model to 175 PS (129 kW; 173 bhp). The six-cylinder model remains unchanged from the 256 PS (188 kW; 252 bhp) 3.6-litre engine.

The Legacy still uniquely offers standard all-wheel drive and horizontally opposed engine layouts, but discontinues the manual transmission for the US market in favor of the Lineartronic CVT on both engine configurations. The US Market variation of the 2016 Legacy achieves a notable 36 highway MPG when equipped with the 2.5-liter flat-four. (Source Wiki)
