Sydney Cup race tightens after SVG's Race 25 disaster

Shane van Gisbergen's Beaurepaires Sydney Cup lead has been slashed after mixed results at the ARMOR ALL Sydney SuperNight.

Van Gisbergen will carry a reduced 28-point lead to this week's BP Ultimate Sydney SuperSprint.

The series leader won the Saturday night race, but slumped to 23rd on Sunday after an early off and later drive-through penalty.

To celebrate Supercars' quadruple-header at Sydney Motorsport Park, Beaurepaires is throwing a $25,000 cash prize behind the first-ever Sydney Cup.

The Beaurepaires Sydney Cup will be awarded to the driver who accumulates the most points over the four rounds being held at SMSP.

The trophy and the $25,000 cheque will be presented to the winning driver at the Race 30 podium presentation of the Beaurepaires Sydney SuperNight on November 21.

Van Gisbergen had previously enjoyed a 42-point lead over Will Davison, who had a series of run-ins with the points leader on Saturday.

Six drivers are within 100 points of van Gisbergen; Davison (28 points behind), Anton De Pasquale (45), Nick Percat (58), Jamie Whincup (61), Will Brown (85) and Chaz Mostert (99).

Nine drivers have already reached the podium in the six races; van Gisbergen; Davison, De Pasquale, Percat, Whincup, Brown, Mostert, Brodie Kostecki and James Courtney.

The 2021 Repco Supercars Championship will resume this weekend at the BP Ultimate Sydney SuperSprint.

Every session of the event will be broadcast live on Foxtel (Fox Sports 506) and streamed on Kayo. The Seven Network will showcase highlights of the event.

Tickets for the event are on sale now.
