The 2006 audi were powered by a 3.5-liter aluminum-block V8 by Audi a6 for sale

It's acknowledged knowledge that Nissan guards its Zama collection in Japan closely. Some say it employs a classified ninja set proficient to reach into an rowdy arithmetical camera, rip out its CCD chip and show it to it before it dies. But a few enterprising Nissan fans did succeed to score a circuit of the warehouse, which holds expanse of cars from Nissan's storied past. Possibly the crown rock in the collection is the road-going R390 GT. It's a one of a kind homologation attempt based on the company's R390 GT1 statement in the 1997 24 Hours of Le Mans. The R390s were powered by a 3.5-liter aluminum-slab V8, designated VRH35L, producing 641 horsepower. As icon has it, only one streetable R390 was built, and it resides in Zama, protected by a force field that can only be turned off for 30 seconds at a occasion, once per each month that has an R in it. That's why Nissan offers a searchable virtual database of the Zama collection (R390GT1).
