The V5 engine is a V form engine with five cylinders.

Volkswagen introduced the first V5 engine, though this engine is not a true twin-bank V engine, but rather a VR5, or staggered bank straight-5 engine, and therefore not a true V5. It does not have one cylinder bank with 2 cylinders and one with 3; rather, it has all 5 cylinders sharing a single bank. The engine is derived from the VR6, and is thus a staggered 5, and has much in common with Volkswagen's earlier straight 5 developed in the 1980s for the Passat and Audi Quattro.

Volkswagen's VR5 is a 2.3 litre gasoline engine descending directly from the older VR6 from which VW removed a cylinder creating the first block to use five cylinders in a V design. The first version, with 2.3 L capacity, was capable of 150 PS (148  hp/110  kW) and had a maximum torque of 209 N·m (154 ft·lbf). It was introduced in the Passat in 1997, and later in the Golf, Bora (aka Jetta) and the Spanish Seat Toledo (Typ 1M) in 1999. In 2000 the head was updated with twin cams, and was equipped with 20 variable timed valves thus raising power to 170 bhp (127 kW; 172 PS).

An engine or motor is a machine designed to convert energy into useful mechanical motion.Heat engines, including internal combustion engines and external combustion engines (such as steam engines) burn a fuel to create heat which is then used to create motion. Electric motors convert electrical energy into mechanical motion, pneumatic motors use compressed air and others, such as clockwork motors in wind-up toys use elastic energy. In biological systems, molecular motors like myosins in muscles use chemical energy to create motion.

Originally an engine was a mechanical device that converted force into motion. Military devices such as catapults, trebuchets and battering rams are referred to as siege engines. The term "gin" as in cotton gin is recognised as a short form of the Old French word engin, in turn from the Latin ingenium, related to ingenious. Most devices used in the industrial revolution were referred to as engines, and this is where the steam engine gained its name.^{[citation needed]}

Valentino Rossi, (born February 16, 1979 in Urbino), is an Italian professional motorcycle racer and multiple MotoGP World Champion. He is one of the most successful motorcycle racers of all time, with nine Grand Prix World Championships to his name – seven of which are in the premier class.

Following his father, Graziano Rossi, Valentino started racing in Grand Prix in 1996 for Aprilia in the 125cc category and won his first World Championship the following year. From there, he moved up to the 250cc category with Aprilia and won the 250cc World Championship in 1999. He won the 500cc World Championship with Honda in 2001, the MotoGP World Championships (also with Honda) in 2002 and 2003, and continued his streak of back-to-back championships by winning the 2004 and 2005 titles after leaving Honda to join Yamaha, before regaining the title in 2008 and retaining it in 2009. He left Yamaha to join Ducati for the 2011 season.

Rossi is first in all time 500 cc/MotoGP race wins standings, with 79 victories, and second in all time overall wins standings with 105 race wins (behind Giacomo Agostini with 122).

Nicholas "Nicky" Patrick Hayden (born July 30, 1981 in Owensboro, Kentucky), nicknamed The Kentucky Kid, is an American professional motorcycle racer, who won the MotoGP World Championship in 2006.

As a youth, racing others twice his age in CMRA, Hayden would often start the race from the back of the starting grid while a family or crew member held his bike upright because he could not touch the ground. Later, at age 17, he was racing factory Honda RC45 superbikes while still in high school. In 1999, he won the AMA Supersport championship on board a privateer Honda. In 2001, his first full season as an AMA superbike racer, he came within 40 points of winning the championship, finishing behind only champion Mat Mladin and runner-up Eric Bostrom. The 2002 season, however, would see Hayden answering the bell: he won the Daytona 200 on a Honda Superbike en route to becoming the youngest ever AMA Superbike Champion, defeating reigning treble champion Mat Mladin, among others. He also entered the World Superbike round at Laguna Seca, making a solid 4th in the first race before colliding with Noriyuki Haga in race two.
