Paul di Resta got his first taste of Force India's 2010 F1 challenger, the VJM03, on Wednesday as F1 testing recommenced at Jerez in Spain.
As was the case for last week's test, running was punctuated by heavy rain storms, however the Scot still managed to complete 76 tours - his best lap a 1 minute 25.088 seconds - before handing it over to Adrian Sutil.
Speaking following his day's work, the Mercedes DTM driver, was happy with what he had accomplished: "Today was my first run in the new car and it felt pretty good," di Resta said.
"The objective was to get as much running as possible and we managed over 300km, which was a great effort, particularly given the bad weather conditions we had over the morning. It seemed to be drying out and then the rain would return again so you were in a sort of no man's land with the tyres.
"Even with this type of weather though I could get an impression of the car. It seems stable and good all round, a genuine improvement on the car I drove last year. I'll be back in the car in Barcelona and am looking forward to it already."
Sutil meanwhile was also pleased and having replaced di Resta at the wheel late on did 28 laps, his best around seven tenths quicker, a 1m 24.272s.
"It was a short session for me today," Sutil continued. "I only started my first run just before 4pm when the track was drying in places but there were still a few damp patches on the racing line.
"We did two long runs on the slick tyres but in the mixed conditions it was hard to get a view on the car. But at this stage all running is really good and we're ready to go out again tomorrow to get some more mileage and data on the car," Sutil summed-up.
