    Nissan R391

    Couldn't find it on here so thought i'd add it

    Nissan R391

    A little bit of history, by John Galt

    Typically, Nissan ran eight cylinder twin turbo motors on their Le Mans vehicles, and turbo charging has always been one of the companies specialties, winning worldwide acclaim with several of the turbo charged entries in the Z-series. However, when it came to the R391, Nissan decided to forego their traditional strategy of using turbo motors and instead work with a much larger naturally aspirated engine. The motor in question was given the badge, "VRH50A", and was an eight cylinder 5.0 liter motor, which was supposed to match the power of the traditional turbo motors, while maintaining an increased amount of reliability and consistent power throughout all RPM ranges.

    Everything seemed promising for Nissan coming into the actual competition, but racing would prove a far different matter than what many expected. Nissan entered three cars in the 1999 Le Mans; two R391's and one Courage chassis with an older generation turbo charged motor. Of the three cars, only the Courage would actually finish the race, as one of the R391 suffered an accident, destroying the car and injuring the driver. The other R391, despite holding it's own at fourth place, suffered a crippling mechanical failure, taking it out of the race permanently. Of course, the race was not a complete disaster for Nissan, and the company still managed to make 8th place with the Courage. However, in terms of the 391, it was a disappointing development, especially for a car that had such high expectations.

    However, the R391 would later reclaim it's honor at the Fuji 1000km event. This time, a newly fixed R391 would take first place, beating out all rivals, even those that had overcome the car at the 1999 Le Mans. It is important to note, though, that competition at the Fuji race was very limited, and Nissan's main competition came from Toyota. This is not to cast shadow over the victory however, as it was Nissan's only first place win in their entire Le Mans program.

    However, the R391's victory was to be it's last, and following the Fuji race, Nissan retired both the car and it's entire program, leaving NISMO to handle performance aspects related only to strictly production vehicles.

    Even though Nissan may have had a less than stellar record racing in the Le Mans, their cars nonetheless represented some very advanced technology and some of the best the automotive field had to offer at the time. The R391 should be a car looked back on fondness and remembered for it's powerful win and the amazing potential that the car had, as well as the innovative and new ideas that went into creating it.

    Was there ever a road car developed for this, or since the rule changes in 98, they decided not to make one?

    Nope that wasn't a GT1 car (unlike the R390). That was a full on prototype.

    My favorite fact about the car has got to be the fact that it made Toyota GT-One completely winless in its entire lifetime....since it beats it at Fuji 1000km....

    This is as much a road car as an Audi R10 or Ferrari 333SP or any LMP cars.....

    You've inspired me to look up the race history of the GT-One. It finished 2nd at Le Mans twice did it not? Was it not a very fast and formidable car?

    2nd once, in 1999. I love the car, just I thought it was pretty funny it never actually won a single race despite the huge following of the car. I am sure Toyota thought they could win the Fuji 1000km....Toyota as a whole have finished 2nd 3 times at Le Mans I believe(92 with TS010, 94 with 94C-V, and 99 with the GT-One).

    and in 1999 they lost because of a puncture at the 23th hour iirc.

    your corrections are always welcome.

    and never blindly trust wiki, they say the 8C uses the same engines of the California, just as an example.
