What's so special about the Nissan GT-R?


assistant
The Nissan GT-R, which initially went into production in 2007, is powered by a hand-built engine assembled by one of only 5 specially-trained technicians (known as Takumi Craftsmen) in a cleanroom in Nissan's Yokohama factory. Early models produced roughly 473 horsepower, with incremental improvements yielding upwards of 560hp in current models.
