In January 2020, there will be an auction organized by Mecum, where the 1968 Challenger II Streamliner will be sold. He holds the absolute speed record among piston-powered cars.
The Challenger II Streamliner was built by American driver Mickey Thompson, who has won numerous drag races and set several records. However, in 1968, due to bad weather conditions, most of the dry salt lake Bonneville, where it was planned to set a record, was closed for two years. The sponsors left the project and the car had to be mothballed.
- Already in this century, Danny Thompson's son decided to end his father's business. He swapped out the two 7.7-liter V8s for a pair of 8.2-liter V8s equipped with three-speed automatic transmissions. The new engines run on a mixture of 87 percent nitromethane and 13 percent methanol. The total power increased from 1,825 to 5,070 horsepower.
- The all-wheel drive Challenger II Streamliner has 68 aluminum panels. The length of the car is 9.75 meters, and the width and height are only 0.91 and 0.94 meters, respectively. The curb weight is 2630 kilograms.
- In 2018, Danny Thompson showed an average speed of 448.757 mph (722.2 km / h) in Bonneville on a car converted to modern requirements. Half a century after its creation, the Challenger II Streamliner still set the world speed record for piston-powered cars.
