Hartley was also the third quickest as the two-day mid-season test got underway.
Ferrari test driver Antonio Giovinazzi finished an impressive two and a half seconds ahead of his nearest rival - Sauber's Marcus Ericsson.
The Italian recorded the fastest lap ever at the Hungaroring, half a second quicker than anything during last weekend's Hungarian Grand Prix.
Hartley, who got through 126 laps, was third fastest, two and a half seconds behind Giovinazzi.
"We had a lot of interesting items to test today and plenty of work in front of us. In the morning session, we completed the most laps of any team with 94 - this was actually quite punchy in the hot conditions," he said.
"We had another busy programme to complete in the afternoon session and ended up with a total of 126 laps, but with the unforeseen weather changes we couldn't complete all of our test items.
"Despite the rain at the end of the day, I have to say it was a really positive test for us."
Hartley will also drive on day two of the test.
The next round of Formula One is in Belgium at the end of the month.
