Tordoff made a clean getaway and built up a controlled half-second lead over Jordan, who climbed a place to second after Dan Cammish was slow away in his Team Dynamics Honda. That allowed Jordan’s teammate Colin Turkington to close, and the top four broke away in a processional opening half of the race.
But with three of the 16-lap race remaining, the rear of Tordoff’s AmD Tuning Civic Honda broke loose on the run out of the high-speed Church corner. Tordoff blamed the error on an electrical issue, which set off an alarm in the car before affecting the power steering.
The loss of momentum allowed Jordan to close and pass prior to the braking zone of the final-corner chicane complex.
Jordan pulled one second clear during his first lap out in front and controlled that to the flag. On the final lap, Tordoff again struggled out of Church and allowed Cammish an attempt at a similar run, but Tordoff held on to second place, with Turkington fourth.
As the leading quartet ran clear, Tordoff’s teammate Rory Butcher headed the Vauxhall Astra of Jason Plato for fifth. Ashley Sutton (Subaru) and Honda’s Matt Neal diced behind, with pre-race points leader Sutton carrying the maximum 54kg of success ballast.
Neal, laden with 18kg, attempted a pass and was fractionally ahead as they braked on entry to the chicane but a nudge from Sutton knocked Neal sideways. He collected the slide and had to cut the chicane, but having already been ahead Neal retained the place to finished seventh ahead of Rob Collard with Sutton dropping down to ninth.
Jake Hill rounded out the top 10 ahead of Josh Cook and Donington Park race three winner Tom Ingram.
After losing his fastest lap for causing a red flag in qualifying, Tom Chilton climbed from 22nd on the grid to 18th, while Mark Blundell progressed from 30th to 27th.
