LONDON (REUTERS) - Aston Martin have started work on a new Formula One factory and wind tunnel that team owner Lawrence Stroll said underpins his commitment to the sport and aim of fighting for world championships in the next three to five years.

The Canadian billionaire told reporters the Silverstone factory and 'campus' would cost £150-200 million (S$279 to S$372 million) and be the most sustainable in Formula One.
