TETBURY'S Jamie Chadwick has confirmed she will defend her W Series title.

Chadwick won this year's inaugural all-female motor racing championship, pocketing more than £400,000 in the process.

And the 21-year-old from Bath, signed by Williams as their development driver earlier this year, will be joined by six new faces, including Brit Abbie Eaton, 27, for the second instalment of the series.

Chadwick won two of the six races this year, sealing the championship at the season finale in Brands Hatch.

The top 12 from last season's championship sealed automatic qualification for 2020.

Britons Alice Powell, 26, Sarah Moore, 25, and Jessica Hawkins, 24, will also be back on the W Series grid.

Next year's champion will be rewarded with superlicence points by motor racing's sporting federation, the FIA, for the first time.

To compete in a Formula One grand prix, a driver must have collected 40 superlicence points. Twenty-five points are needed to take part in practice.

It is understood that the winner of the W Series in 2020 will be awarded 15 points. It has been more than 40 years since a female driver last contested an F1 race.
