[5] [11] Called the kontra engine, it was a boxer-twin design. Early uses of flat engines in cars include the 1900 Lanchester 8 hp Phaeton boxer-twin, the 1901 Wilson-Pilcher boxer-four, [12] the 1904 Wilson-Pilcher 18/24 HP boxer-six and the 1903 Ford Model A, the 1904 Ford Model C and the 1905 Ford Model F.

A flat-four engine, also known as a horizontally opposed-four engine or boxer engine, [1] is a four-cylinder piston engine with two banks of cylinders lying on opposite sides of a common crankshaft. The most common type of flat-four engine is the boxer-four engine , each pair of opposed pistons moves inwards and outwards at the same time.
Continental O-470-13A air-cooled aircraft engine. A flat-six engine, also known as a horizontally opposed-six, is a six-cylinder piston engine with three cylinders on each side of a central crankshaft. The most common type of flat-six engine is the boxer-six engine, where each pair of opposed cylinders moves inwards and outwards at the same ...
The most common type of flat-twin engine is the boxer-twin engine, where both pistons move inwards and outwards at the same time. The flat-twin design was patented by Karl Benz in 1896 and the first production flat-twin engine was used in the Lanchester 8 hp Phaeton car released in 1900. The flat-twin engine was used in several other cars since ...
It was a problematic engine, and so only used in the North American market in type 2 vehicles for model year 1966. 1966 Volkswagen Beetle (Europe, North America) 1966-70 Volkswagen Beetle (Europe, Non-USA) 1966 Type 2 (North America) 1971-73 Type 2 (Non USA) AB Engine code; 1971-72 Non USA Low octane markets AC Engine code
The Porsche flat-six engine series is a line of mechanically similar, naturally aspirated and sometimes turbocharged, flat-six boxer engines, produced by Porsche for almost 60 consecutive years, since 1963. [8] [9] The engine is an evolution of the flat-four boxer used in the original Volkswagen Beetle. [10] [11] [12
A flat-eight engine is able to have perfect primary balance and secondary balance. A boxer-eight engine has a single piston per crankpin, which increases the linear offset between the cylinder banks. A boxer-eight with nine main bearings may be thought of as two boxer-four engines laid end-to-end with a 90° phase angle between their crankshafts.
Does it mean "180 degree V engines" (i.e. non-boxer type) or does it mean V engines with some angle (e.g. 60 degree or 90 degree)? 4. It seems that the true distinguishing characteristic of boxer vs. non-boxer type of flat engines is the "horizontally-opposed" nature of them. If we can get agreement on this item, we'll be closer to a consensus.
