Following a successful first campaign with GT3 cars, the DTM returns this year with an expanded grid of 29 cars - the biggest field since the revival of the championship in 2000.
A lot of eyeballs will be on nine-time World Rally champion Sebastien Loeb as he makes his DTM debut for Red Bull in place of Nick Cassidy. Loeb has plenty of experience in circuit racing and could potentially upset the frontrunners this weekend.
Another star attraction on the grid will be three-time champion Rene Rast, who returns to the DTM after a year's absence to lead the Abt Audi team.
Other notable drivers on the grid including BMW's Marco Wittmann, Porsche GT ace Laurens Vanthoor, Lamborghini's factory driver Mirko Bortolotti, Le Mans class winner Nicki Thiim and Audi star Nico Muller.
Six different manufacturers will battle for top honours at Portimao following Porsche's long overdue entry to the DTM. The Stuttgart-based brand will be up against fellow German powerhouses Audi, BMW and Mercedes as well as Italian supercar makers Lamborghini and Ferrari.
