Chris Smiley secured the quickest time of the afternoon at the TOCA Test Day from Thruxton with an effort narrowly shy of Dan Cammish's morning benchmark.
Both the factory Honda Civic Type R (FK8) of Cammish and BTC Racing's new-for-2019 FK8 lapped beneath the official qualifying lap record (1m15.612s) set by Matt Neal last year with the same machinery in its debut BTCC campaign.
"This morning was the first time I'd driven at this circuit in this car before and around real high speed corners," said Smiley. "So, the first session was about trying not to cause any damage - driving the car to where I thought was safe. Despite losing the tyres towards the end, I was matching the times we were doing early on so that's a good sign.
"This is a track that you have to treat with respect and in the second session we'd looked back through the data and got a feel of things and had a better idea of what we had to do."
Rory Butcher in the Cobra Sport AmD AutoAid/RCIB Insurance Honda Civic Type R (FK2) rounded off a top-three lockout for the Japanese marque in the combined classification. The Scot was encouraged to follow a maiden BTCC win back at Brands Hatch with more positive progress.
"We're quick," said Butcher. "It's a really demanding circuit here and it takes a lot to hook up a qualifying run. It's intense because it's just so fast.
"We went through a few changes on the car and they were positive. Looking towards the Thruxton race weekend, we're feeling strong. One change in particular has given me a lot more confidence and after five, six, seven lap runs we were hitting good pace."
On the whole, the second session saw drivers outperforming their morning efforts, though, of course, all times in testing are to be taken with a pinch of salt as teams work their way through packed schedules with varying priorities. The 29 cars out there racked up some 1200 laps over the course of the day.
The Adrian Flux Subaru Racing Levorg of Ash Sutton and Colin Turkington in the Team BMW 3 Series could again be found at the sharp end, with third and fifth respectively - sandwiching Aiden Moffat, who managed the fourth fastest time of the afternoon.
Cammish tallied the sixth quickest lap in Free Practice 2 to go along with his standout time set in the morning's running.
