Honda S-Dream sets 261.875 mph land speed record at Bonneville
The Honda S-Dream, powered by a turbocharged 660cc three-cylinder engine, has become the fastest Honda ever with an FIA-certified 261.875 mph run at the Bonneville Salt Flats.
Honda has claimed a new speed record with its S-Dream streamliner, reaching an FIA-certified 261.875 mph (421.45 km/h) over a mile at the Bonneville Salt Flats. The car, built by Honda's Japanese engineering team, now holds the title of the fastest Honda ever.
The S-Dream project targeted the FIA's Category A, Group 1, Class 4 (up to 1,000cc) land speed record. The team started work in 2015, focusing on extracting maximum performance from the tiny 660cc engine found in the Honda S660 kei car. In standard form, the S660 produces just 64 hp, but for Bonneville, Honda engineers increased output to more than three times that figure, estimated at over 200 hp.
Aerodynamic design and technical approach
Rather than relying on massive displacement or extreme power figures like production hypercars, the S-Dream was designed for minimal drag and high-speed stability. The car's slender, low-profile bodywork was developed specifically for land speed racing, with every surface optimised to cut through the dense Bonneville air. The record was achieved with a turbocharged three-cylinder engine, a configuration rarely seen at these speeds.
The S-Dream's achievement stands out in a field where most record-breaking cars use engines producing well over 1,000 hp. Honda's approach demonstrates what can be accomplished with careful engineering and a focus on aerodynamics rather than brute force. The record also highlights the versatility of Honda's small-displacement turbocharged engines, which are more commonly found in city cars than in land speed racers.
What it means for Honda's engineering reputation
For Honda, the S-Dream project is a showcase of technical ingenuity and the brand's willingness to compete on a world stage outside conventional motorsport. The record run at Bonneville demonstrates that Honda's engineering teams can extract remarkable performance from modest hardware, reinforcing the company's reputation for innovation in engine design and vehicle development.
