Captain G. E. T. Eyston's recordbreaker Thunderbolt has been modified to bring it in line with the knowledge gained on its first trials in America last autumn. It is understood that the in reifications include further streamlining, lighter, and still more efficient brake gear, enclosed cockpit, coil suspension, Lockheed hydraulic servos, and novel type of air brakes and a longer tail. The giant car. with Its Rolls-Royce aero engines, has already proved extremely useful as a trial unit for engines of high power geared together, four-wheel steering at speed, and disc brakes, in addition to cooling problems where big power is employed, and in the development of tyres for the largest vehicles in the world to-day. It is not known what new speed is likely to be achieved oQ the next runs at Utah: so much depends on local conditions.
