Since the relaunch of the DTM in 2000, no manufacturer has ever won the title three years in a row. That could all change this season, as Audi attempts to keep the crown away from Mercedes yet again, and Bernd Schneider's 2006 championship becomes a distant memory.
But Mercedes has not taken the past two defeats lightly. The pace of Audi's new A4 straight out of the box last year left Merc with a lot of work to do to catch up, but its development over the season was impressive, and there was little between the cars by the end of the year.
On his rise through the ranks before reaching Formula 1, Lewis Hamilton was usually a cut above the rest. But he never truly asserted himself over a Mercedes-backed fellow Briton who traded single-seaters for touring cars and is now seeking new opportunities after a year largely spent on the sidelines

Switching to GT3 regulations marked a fresh start for the DTM in 2021, but it has also drawn a line in the sand against other series using similar cars by engaging AVL Racing to develop a bespoke Balance of Performance system. Here’s how it works

But despite some initial BoP-based teething troubles, there were some pleasant findings as the 'new DTM' got underway at Monza
The DTM moves into its bold new GT3 era with welcome support from Red Bull, which enters two AF Corse-run Ferraris. That includes one for ex-F1 driver Alex Albon, who’s determined to make a success of his GT switch - but he knows it won't be easy...
It's taken him a while to emerge as a consistent title challenger, but in the final year of DTM's Class One rule set, Nico Muller has smoothed the rough edges and has double champion stablemate Rene Rast working harder than ever to keep up in the title race
Opel's fortunes in the DTM had taken a turn for the worst by 2003 - hardly the pedigree that suggested it could take on the toughest 24-hour race of them all. But that's exactly what it did
