The Grove-based BMW Williams F1 Team are happy after concluding the first 2002 season test with four days of intense work in Barcelona.

Ralf Schumacher, Juan Pablo Montoya and Marc Gene were joined by the test team's new official driver, Antonio Pizzonia who claimed the best time on the first day.

Running three cars, including two interim chassis with the new BMW engine, the team concentrated on durability and the reliable running of the entire powertrain, as well as testing the brakes and software.

Chief operations engineer for Williams F1 Sam Michael said:"We managed to complete significant mileage in dry, intermediate and wet conditions, which will make a positive contribution to both Michelin's tyre work, and has provided significant reliability and durability for the new engine and gearbox.

"We also made some good progress, with some brake developments and electronic control software analysis."

The Enstone-based Renault F1 team of Jenson Button and Jarno Trulli's testing was hit by bad weather.
