One indicates by V8 an Engine spark-ignition comprising 8 Cylindre S laid out out of V.
V8 is thus a architecture of internal combustion engines. 4 Cylinder S on line representing the left branch of V and 4 others Cylinder S representing the right branch of V.
The V8 engines are in general powerful engines which consume in particular more gasoline than the other engines assembled in series, the such four cylinder motors. One can however note that the most recent types, called to variable cubic capacity, are able to decontaminate four their cylinders when the required power is low (generally, therefore), at the point to be famous more sober than certain V6. One finds mainly the V8 engines in the American manufacturers , Australia German NS and , more rarely at the Italy NS (only on the sporting cars) and sometimes at the Japan board (top-of-the-range).
The V8 engines and France
In the years 1970, Peugeot, Renault and Volvo (PRV) wishes to conceive common V8 for their respective cars. The Oil crisis of 1973 obliges them to cut two cylinders to the engine. This last became then the V6 PRV.
For this time, no large French manufacturer has manufactured of engine having more than 6 cylinders, except for the W16 of the Bugatti Veyron but which is based on a German technology, Bugatti pertaining to the group Volkswagen. In the same way, Renault calls upon engines Asian S for some of its V6.
However, in automobile competition, the French manufacturers showed that they were able to design engines V8 and V10 of good quality. Renault for example showed that it was possible to beat Ferrari, Mercedes or BMW with its V8 and its V10 (see the prize list of Renault F1 TEAM). Peugeot as showed to him as its V10 could be better than those of competition to the 24 hours of Mans (see the Peugeot 905).
