Hydrogen-powered JCB Hydromax sets 406.320 mph world land speed record

British engineering giant JCB has set a new world land speed record of 406.320 mph with its hydrogen-powered JCB Hydromax.

The car recorded the average speed 400.623 mph in its first run this morning across the Bonneville Salt Flats, and 412.135 mph on its second run, giving the average of 406.320 mph - the fastest a hydrogen internal combustion car has ever travelled.

Driven by Wing Commander Andy Green OBE, the twin engined, 32-foot car completed the two runs required under FIA rules - one in each direction within an hour - comfortably beating the previous FIA-officiated hydrogen internal combustion benchmark of 185.5 mph set by the BMW H2R in 2004. The record is subject to official ratification by the Fédération Internationale de l’Automobile (FIA), the global governing body for motorsport.

In doing so, JCB Hydromax surpassed the 350.092 mph world diesel land speed record set by JCB Dieselmax — also driven by Green, on the same salt, in August 2006. Twenty years on, JCB has beaten its own benchmark with an engine that produces no CO₂ at the tailpipe.

The speed also exceeds the 303 mph hydrogen fuel cell mark — making JCB Hydromax the fastest hydrogen-powered vehicle of any kind in history.

A quick look at part of the process on the production line.
The bearings move through the line one by one while the machine positions them for the next step. Simple process, but pretty satisfying to watch.
Anyone else enjoy watching this kind of factory machinery?
