But it is also considered a flat engine because of its shape.

Flat engines also help to lower the vehicle's center of gravity.

It is similar to the H engine which couples two flat engines.

Flat engines are also used in some Ferrari's with 12 cylinders.

An H engine can be viewed as two flat engines, one atop or beside the other.

The A-0 also had a flatter engine cowling, which gave the pilot a much better field of vision.

Subaru also asserts that the flat engine has inherently low vibration.

Flat engines have a lower center of gravity than any other common configuration, so vehicles using them should benefit from better stability and control.

It is a flat engine with two cylinders.

"I think these other bikes were noticeably top-heavy compared to the flat engine," he said.

The flat engine allows the car to sit low, comparable to Porsches and other supercars.

One notable example was the installation of flat engines on the formerly-radially-equipped Beech 18.

The low centre of gravity allowed by a flat engine can reduce body roll in automobiles and enhance handling precision.

When mounted longitudinally in a vehicle, flat engines with up to six cylinders are short, low, and wide.

Pairs of cylinders oppose each other in a boxer flat engine or "X" arrangement.

Flat engines use two opposing banks of cylinders and are less common than the other two designs.

An important factor in aircraft use is the flat engine's absence of vibration, which allows a lighter engine mount.

Flat engine in front, two-blade tractor propeller, 2.3 m diameter.

Flat engine, two banks of cylinders directly opposite each other on either side of the crankshaft.

That said, you'll struggle to get over the slightly flat engine note which is quiet for a diesel but uninspiring for a performance car.

In 1896, Benz designed and patented the first internal-combustion flat engine, called boxermotor.

A flat engine is an internal combustion engine with horizontally-opposed pistons.

Engines of this design are often referred to as flat engines because of their shape and lower profile.

This differs from a flat engine because it is essentially an inline engine laid on its side.

Variant with Lycoming flat engine, modified wings and improved aerodynamics, produced from 1998.
