The clock is ticking for Modern Car Collector readers who want a shot at the fastest, most powerful Corvette ever built. The Chip Miller Amyloidosis Foundation’s blockbuster sweepstakes for a 2026 Corvette ZR1 with the ZTK Performance Package closes for good on September 27, and for these final days our readers get a special perk: every entry placed through our link comes loaded with double the bonus entries, so the same donation now goes twice as far toward the keys to this Competition Yellow Tintcoat ZR1. Enter now for double entries before time runs out.
This is not an ordinary giveaway car. The ZR1 revives the King of the Hill nameplate with the most powerful production V8 ever built by an American manufacturer, a twin-turbocharged 5.5-liter flat-plane-crank engine called the LT7 that produces 1,064 horsepower. A towering carbon-fiber wing, underbody strakes, and dive planes generate the highest downforce of any production Corvette in history, and the car is currently sitting on the showroom floor at Ciocca Corvette in Atlantic City for anyone who wants to see it in person. Check out the double-entry sweepstakes here before the September 27 close date.
The cause behind the giveaway matters just as much as the car. Chip Miller co-founded Carlisle Events and built Corvettes at Carlisle into one of the largest gatherings in the collector car hobby before he passed away from complications of Amyloidosis in 2004. The foundation created in his name funds research and awareness for this rare disease, and every entry placed during these final days helps move that mission forward while doubling a reader’s own odds of winning. Donate and enter with double entries to support the cause today.
Getting in on the double-entry bonus is simple. The foundation offers donation tiers from $25 up to $2,000, and every tier already comes loaded with a matching batch of promo entries, so a $100 gift that normally carries 90 entries stacks another 90 on top through our link, and a $500 gift stacks 650 additional entries on top of the standard 650. Pick an entry level and claim double entries here while the bonus is still active for Modern Car Collector readers.
Mark the calendar, because there is no extension coming. The sweepstakes closes on September 27, 2026, at 11:59 p.m. Eastern, with the winning ticket drawn on October 3 at the Carlisle Fairgrounds in Pennsylvania, and the winner can even choose a $175,000 cash option instead of the car. With the deadline just weeks away, this is the moment to lock in a double-entry gift before the window closes for good. Lock in double entries before September 27.
A chance at the quickest, most powerful Corvette ever built, doubled entries for these final days, and support for Amyloidosis research in Chip Miller’s name all in one gift is a rare combination for any collector. Modern Car Collector readers can click here to enter the 2026 Corvette ZR1 sweepstakes and get double entries before the September 27 deadline arrives for good.
