Additional use
editThe BMW i3 electric car uses a parallel twin engine as a range extender.
The add on is called the REx and is same/similar as a BMW C600 Sport and C650GT scooter engine.

Terminology
edit(This post kind-of follows the "Parallel Twin" post above).
I think the paragraph (in italics, below), from the Terminology section is wrong. There is no difference between a parallel twin and a vertical twin. It is NOT a question of their crankshaft angles. One simply describes an engine as a 360°,180°, 270° parallel-twin (or vertical twin).
"In the United Kingdom, the term "parallel-twin" is traditionally used for engines with a crankshaft angle of 360 degrees, since the two pistons are in the same direction (i.e. parallel to each other).[citation needed] "Vertical-twin" was used to describe engines with a crankshaft angle of 180 degrees,[citation needed] which causes the pistons to travel in opposite directions. The terms "straight-twin" and "inline-twin" were used more generically for any crankshaft angle." Arrivisto (talk) 12:46, 19 May 2023 (UTC)
