Australian F1 driver Mark Webber's future at Red Bull "is in doubt and judging by comments coming from the team over the weekend, fellow Australian Daniel Ricciardo may be in the box seat to replace him next season," according to THE AGE. Red Bull Team Principal Christian Horner has repeated his assertion that 36-year-old Webber is ''in the autumn of his career and no longer in the spring,'' while team adviser Helmet Marko has talked up Ricciardo's efforts this season. Horner said, ''It is impossible now to say who will be driving alongside Sebastian [Vettel] next year. It's clear every driver would at the moment like to be sitting in a Red Bull." Webber is contracted until the end of the '13 season (THE AGE, 5/14).
WILLIAMS HYBRID BUS: BLOOMBERG's Alex Duff reported Williams Grand Prix Holdings Plc CEO Alex Burns said that the team "expects to start street testing of a hybrid London double-decker bus this year as it seeks a revenue boost from technological expertise." The nine-time F1 constructors' champion and bus operator Go-Ahead Group Plc 14 months ago "agreed to make six prototype vehicles with flywheels that recoup energy from braking, a system Williams developed for racing." Burns said that Williams and Go-Ahead "are testing one prototype off public roads that has shown 'very promising' fuel saving" (BLOOMBERG, 5/13).
