This engine featured three banks of six cylinders set 60 degrees apart. The Bugatti EB 118 show car debuted in 1998. ... The Bugatti EB 218 was a concept sedan. ...
They and Bugatti EB 18/4 Veyron concept featured a variation of this engine - it retained the 18 cylinders but instead of three cylinder banks, it had four. This confused many who saw the specification in print at motor shows since 18 isn't evenly divisible by four. The design was loosely based on the concept Volkswagen used for its V5 engines which had one bank with three cylinders and one band with only two. Essentially the four-bank W18 was two V9 engines (one bank of five cylinders and one band of four) mated to a common crankshaft. Ultimately the design proved to be impractical and the W16 (four banks of four cylinders) layout was adopted in the next generation of the concept, the Bugatti EB 16/4 Veyron.

Usually found in 4 and 6 cylinder configurations, the straight engine or inline engine is an internal-combustion engine with all cylinders aligned in one row, with no or only minimal offset. ... A V engine is a common configuration for an internal combustion engine in which the pistons are aligned so that, if viewed along the line of the crankshaft, they appear to be in a V. The V configuration reduces the overall engine length and weight compared to an equivalent straight... VR6 is an engine configuration developed by the Volkswagen Group. ...
