Porsche built exactly 918 examples of its 918 Spyder hybrid hypercar, but few wear a stranger, more personal specification than chassis 590. Consigned through Broad Arrow Auctions for The Quail Auction 2026, this 2015 example pairs a Paint to Sample Grey Black exterior with a Color to Sample white leather interior, a combination that sets it apart from the silver and GT Silver cars most collectors picture when they think of Porsche's hybrid flagship. The listing carries a pre-sale estimate of $3.25 million to $3.75 million, offered entirely without reserve.
The grey-black hue first appeared on the 997-generation GT3 RS, and only a handful of 918 owners worldwide chose to carry it over to their hypercar. This particular car goes a step further by deleting the model's signature Acid Green accents in favor of grey-piped white leather inside the cabin. Factory paperwork shows the original buyer also added a front axle lift system, a full carbon fiber interior package, carbon fiber mirror caps, and roughly $7,000 in custom tailoring on top of the base build. A later owner swapped in Porsche's lightweight Weissach magnesium wheels, trimming about 33 pounds of unsprung weight.
This 918 is also one of only 300 examples built for U.S. VIP customers, and its history shows just three caretakers from new. Delivered through Niello Porsche in Central California, it was serviced there until 2023 at roughly 4,000 miles before passing to its current owner, who has kept it under the care of Porsche San Luis Obispo. At the time of cataloging, the car shows 5,635 miles and comes with its original window sticker, books, portable charger, and indoor car cover, the kind of paper trail that matters almost as much as the paint to serious buyers.
The 918 Spyder traces its roots to the Carrera GT and the 3.4-liter V8 that powered Porsche's RS Spyder Le Mans racer, technology that eventually grew into a 4.6-liter, 608-horsepower production engine. Paired with front and rear electric motors, the finished car sent a combined 887 horsepower and 944 pound-feet of torque to all four wheels through a seven-speed PDK transmission, enough to become the first road car to lap the Nurburgring Nordschleife in under seven minutes. It arrived alongside the Ferrari LaFerrari and McLaren P1 as one of three defining hybrid hypercars of the early 2010s, and independent testers at the time clocked it as the quickest-accelerating of the trio.
Hagerty's valuation tools currently place a #3-condition (Good) 2015 918 Spyder at roughly $1.95 million for a standard car and about $2.25 million for a Weissach-package example, figures that make this car's estimate look aggressive at first glance. Recent results suggest personalization is becoming its own line item on the 918's price tag, though: a Guards Red Weissach car sold for $3.2 million earlier this year, and a rare Liquid Metal Chrome Blue example headed to Zurich carrying a similarly bold estimate. This Grey Black car, offered not long after another 918 crossed the block at Broad Arrow's Monterey sale, looks built to test just how far that premium can stretch.
The Quail Auction 2026 lands during Monterey Car Week, historically the busiest stretch on the collector car calendar, and a no-reserve hypercar with this much documentation and this little competition for its specification should draw plenty of attention when it crosses the block.
