The Honda S-Dream managed 261.875 mph with a turbocharged three-cylinder engine for power.

To reach over 260 miles per hour (418.4 kilometers per hour), hypercars like the Hennessey Venom GT and Bugatti Veyron Super Sport require massive engines that churn out well over 1,000 horsepower. However, the incredibly aerodynamic Honda S-Dream just set an FIA class record on the Bonneville Salt Flats by reaching nearly 262 mph (418.4 kph) in a vehicle with a 660-cubic-centimeter turbocharged three cylinder.

Officially, the S-Dream managed new records of 261.875 mph (421.45 kph) over a mile and 261.966 mph (421.59 kph) over a kilometer. Those speeds also make the swoopy vehicle the fastest road-going Honda ever. You would need a HondaJet to achieve higher speeds in the brand's products. One run even reached 266 mph (428.1 kph), but the car wasn't able to repeat the performance going the other way, so it didn't count as a record.

Sixteen members from Honda's engineering team in Japan started working on the Bonneville Speed Challenge in 2015. Their goal was to set a land speed record using an engine out of a Honda S660 roadster with just 64 hp in stock form. To achieve the milestones, the crew had to overhaul the powerplant including replacing the lower portion of the engine block with a steel version. Honda doesn't give away the mill's exact output but confirm it's over three times more than from the factory. That means the little three-cylinder is making around 200 hp.

The S-Dream performed flawlessly during test runs in Japan, but the driver discovered the lack of landmarks on the salt flats made it difficult to keep the vehicle pointed straight down the course. The team then visited Honda Performance Development in California, and they reshaped the canopy for better visibility. However, the vehicle wasn't able to set a record during the famous Bonneville Speed Week.

The crew eventually got another opportunity to run down the salt, and the S-Dream managed a record-setting 227.776-mph run on the first day. The speeds only increased from there.
