Atech CRS Grand Prix were the pacesetters in last week's GP3 tests in Estoril, posting the overall fastest time in two tests and consistently in the top three in four of the six sessions at the Portuguese track. The new team, formed at the end of 2009, have been regular front runners during the 2010 GP3 season, scoring several podium finishes with Roberto Merhi.

Last week the Silverstone-based outfit ran cars for Atech GP's Formula Renault UK racers Tamas Kiss, Nick Yelloly and Marlon Stockinger, for whom it was their first time in a GP3 car. On the second and third day they were joined by another GP3 rookie Michelin Formula Renault UK Championship runner-up Lewis Williamson.

The first test since the conclusion of the series understandably had the more experienced GP3 drivers setting the early pace. However, by the afternoon session 19 year-old Kiss, third in the Renault UK series, was up to speed, posting the third fastest time of the 30-car field.

Swiss-Filipino Stockinger was an impressive eighth fastest having completed just 26 laps in the afternoon with Yelloly just outside the top ten in 14th.

Day two saw Williamson take over the team's third car from Stockinger, completing 44 laps in the morning session. By the afternoon the youngster had completed another 35 laps and set the fastest time of the day while both Yelloly and Kiss tried various setup changes to their cars.

The final day once again produced an impressive performance by Williamson, the young Scot second fastest in the morning session just 0.125 seconds behind the more experienced GP3 race winner Adrien Tambay. In the afternoon, 20 year-old Williamson leapt to the top of the time sheets after a superb performance on new tyres late in the session.

Team Principal David Hayle was delighted with the performance of each of the four drivers who all showed an impressive turn of speed over the course of the three days: "I'm very happy with the test last week, it proved very successful for us as a team, and the drivers all performed very well, particularly as they were all new to GP3.

"The GP3 car is very different to what they're used to in Formula Renault and they all adapted very well. Each of them showed great potential and improved over the course of the test. It was particularly good for Tamas, third on day one and Lewis fastest on the second and third days but both Nick and Marlon also showed tremendous pace and talent which backed-up their strong results in Formula Renault this season."

The team will be back on track next week in Jerez for the second three-day post-season test on 20th-22nd October.
