Mercedes's title-defending car will be tested at Silverstone
Team boss Toto Wolff has revealed that Mercedes will launch their title-defending car on the eve of first winter test.
"We are on schedule and have a clear idea of where we are in terms of chassis and engine," he told Italy's La Gazzetta dello Sport.
Wolff has made it clear that his mind is on ensuring Mercedes stays at the top of F1.
"The first goal is to assemble the car in time for mid January," he said, "when we plan a test at Silverstone."
"But only at Jerez will we have a picture of the balance of power with the opposition."
When asked if he knows when the W06 will be officially launched, Wolff answered: "No, but I do not exclude that it will happen right before the first test in Spain."
Mercedes won't go into the new season feeling relaxed after dominating the 2014 season. He said "When you begin to relax, you begin to lose".
