The minivan wins 21st overall.

Toyota has released a short video documenting its adventures in the 2016 One-Lap of America with an unlikely candidate: a Toyota Sienna.

The minivan in question started out as a stock Toyota Sienna SE, and retains the original 3.5-liter V6 and 6-speed automatic transmission, wholly unmodified. However, a cold-air intake and 3-inch cat-back exhaust is said to increase horsepower by some 40 ponies, to 306. Combined with an 800-pound weight reduction to 3,800 pounds, about the power-to-weight ratio of a Ford Focus ST.

Add to that a ton of work with the suspension, a chassis-stiffening roll cage, and 18-inch Enkei wheels with aggressive rubber and you have a family hauler that not only took first place in One-Lap's Truck/SUV Class (apparently, there wasn't a class for minivans), but 21st overall in a field that included Nissan GT-Rs, Mitsubishi Lancer Evos, Chevy Corvettes and BMW M-cars.

The One-Lap of America is an evolution of the cross-country Cannonball Run, but done legally. Entrants caravan across the US to various road courses and drag strips, where they compete against each other in timed events. While the legs driven on public roads are non-competitive, it means the race cars have to be street legal and capable of driving over 2,800 miles in seven days.
