Most flat-four engines are designed so that each pair of opposing pistons moves inwards and outwards at the same time, which is known as a "boxer" configuration (somewhat like boxing competitors punching their gloves together before a fight). In 2012, a naturally aspirated version of the Subaru FA engine was used in the Toyota 86 (also called the "Subaru BRZ" and "Scion FR-S") rear-wheel drive sports coupe. A flat-four engine, also known as a horizontally opposed-four engine, is a four-cylinder piston engine with two banks of cylinders lying on opposite sides of a common crankshaft. This offset distance means that the equal and opposite forces from each cylinder pair produces a rocking couple. ...and why not every flat engine is a boxer. In aircraft, this avoids the need to carry heavy water cooling systems. The 1936 Tatra T97 pioneered the rear-engined, air-cooled flat-four, backbone chassis layout (later used by the Volkswagen Beetle), and at the same time, though unrelated, came the Steyr 50 from Austria, sporting a front boxer 4 engine with rear wheel drive. The real news with the 2020 Outback's engine options is the new-to-Outback 2.4-liter turbo-four. The cylinder block height is the same 202 mm. Unusually for its day, the bore and stroke were equal, with each being 95 mm (3.7 in). It must be stated that gasket leaks can and do persist without the formation of spots on the driveway. Instead, according to the most recent reports, both the 86 and BRZ will receive a non-turbo version of Subaru's 2.4-litre boxer engine, which would see outputs increased from their current levels (152kW/212Nm) to a healthy 162kW and 240Nm.
