The all-new McLaren Speedtail has been breaking its own speed records at testing in the United States this week.

The tests were completed at the Kennedy Space Center in Florida, a venue which is well known for breaking barriers and it was announced that McLaren’s chief test driver, Kenny Brack had reached the top speed of 250 miles per hour (403 kilometres per week) no less than 30 times on the Bohmer Proving Ground’s runway.

The 250mph mark breaks McLaren’s previous record of 240mph which was achieved with their iconic F1 supercar.

"It's fitting that the Speedtail's high-speed test program concluded with multiple maximum-speed runs at a location strongly associated with pushing the boundaries of extreme performance and engineering excellence," McLaren Automotive CEO, Mike Flewitt, says.

"The Speedtail is a truly extraordinary car that epitomises McLaren's pioneering spirit and perfectly illustrates our determination to continue to set new benchmarks for supercar and hypercar performance."

McLaren will build just 106 Speedtails, costing in the region of £1.75million and though deliveries are expected to begin in February, if you haven’t ordered yours already you are out of luck as they have all sold out.
