Toyota Hybrid Synergy Drive Engine
In 1997, Toyota released the world's first mass-produced hybrid vehicle, the Prius, in Japan. The first hybrid engine had a 1.5 liter VVT-i transversely-mounted petrol engine combined with an electric motor. The hybrid offered a number of benefits, the most appealing being a tendency toward better fuel efficiency than its all-gasoline peers.

Horizontally Opposed Engine
Also known as a Boxer engine, this was the first internal combustion engine developed by Karl Benz in 1896. Here the pistons move in a horizontal plane and are found in two banks on either side of the crankshaft. Because this engine has a lower center of gravity, it improves the handling of vehicles that use it.

Scuderi Engine
This split-cycle internal combustion engine was invented by Carmelo J. Scuderi. It uses two paired cylinders which carry out the strokes of a normal engine. One, called the compression cylinder, handles intake and compression duties while the other, the power cylinder, performs combustion and exhaust duties. The engine is said to be more efficient and produce fewer emissions.

Although V8 engines had been in production and use since 1902, the "average mass-market consumer" only had access to inline-four and six-cylinder engines because multi-cylinders (V8s and V12s) were used within luxury vehicles, such as the Cadillac. In 1932, Ford released the affordable mass market V8 engine which became known as one of Ford's most important historical developments.

Straight-Six Diesel Engine
The Cummins B6.7, pictured above, is the latest version of a straight-six engine to be produced for light duty trucks. Identified by its six cylinders being mounted in a straight line along the crankcase, a straight-six engine provides the advantage of amazing engine balance and a cleaner simple design with quick access to key parts, such as spark plugs. However, it also struggles in being extremely cumbersome to package into a vehicle design. A long engine simply doesn't have the compact fit other engine models do.
