GP3: Boschung tops day two of Estoril test

Jenzer Motorsport driver Ralph Boschung led the way on the final day of GP3's opening pre-season test at Estoril. The 17-year-old Swiss driver set his 1m27.789s lap midway through the morning session, which was dry, unlike the first day's action on Wednesday.

On his 21st birthday, Arden's Marvin Kirchhofer was Boschung's closest challenger, almost two-tenths adrift, while Emil Bernstorff, Jimmy Eriksson and day one pacesetter Antonio Fuoco completed the top five. Fuoco's Carlin teammate Mitchell Gilbert was sixth fastest, before topping the afternoon session.

In warmer conditions, Gilbert's 1m28.517s was 0.728 seconds off the morning benchmark, but still good enough to lead Matheo Tuscher, Bernstorff, Pal Varhaug and Boschung.

Confirmed by Carlin as its third driver on the eve of the test, Jann Mardenborough was eighth in the morning and 10th in the afternoon and the busiest driver of the day, logging 103 laps.

Valencia will host the next pre-season test on April 9-10.
