Clad in pink, the network descended upon Brands Hatch to make the final race weekend of the season one to remember for HiQ's official charity.
HiQ's team of pink girls were on hand to give away caps and replica cars in return for donations to the cause.
And after counting the particularly heavy collections buckets from Sunday, the network can now reveal that £5,000 was raised through generous donations.
HiQ's marketing manager Geraldine McGovern said: "We can't thank everyone enough for making our fundraising effort such a huge success.
"We have always been amazed by the on-track action at each BTCC race weekend, but even that pales into comparison when we think of how brilliant each and every fan of the series is.
"From the moment we became involved in the championship in 2008, we've benefited from the support and interest shown from spectators in everything we do.
"Never more has this been in evidence that on Sunday, when we were taken aback by the levels of support from everyone at the circuit - from the fans right through to the trackside marshals, who were particularly fantastic."
The money will now play a huge role in helping HiQ to hit the £100,000 target it aims to reach for the charity.
