Bruno Spengler believes BMW is in excellent shape ahead of the new DTM season after making "another step forward," during three days of testing at Estoril in Portugal.
Spengler, who switched from Mercedes to BMW during the winter, was one of six drivers on hand for the manufacturer, who completed more than 2,500 miles of running this week. The Canadian now thinks BMW can be quietly confident about its hopes of running competitively from the outset.
"I think we made another step forward with this test," Spengler said. "We managed to try out many things and learned a lot. That's exactly what you want during a test at this stage of the season's preparations."
BMW motorsport director Jens Marquardt said that it was crucial that the current rate of development was maintained for the next month, with the DTM's homologation deadline on March 1 looming.
"Every test is very important for us, particularly in the current phase, as we are fast approaching the homologation deadline," Marquardt added. "After this point, much of the development work on the car is subject to a freeze.
"Furthermore, improving the car's performance is another central issue. We were once again able to find a lot of important things in this area. All in all, we enjoyed another three positive days of testing in Estoril."
Reigning champion Martin Tomczyk was testing for the first time since the confirmation that he would race for the new RMG squad this year. Test driver Marco Wittmann drove the other RMG car as Joey Hand was busy with ALMS testing duties at Sebring.
Spengler's Schnitzer teammate Dirk Werner and RBM drivers Andy Priaulx and Augusto Farfus were also on track.
