Audi, Volkswagen group's premier car brand, expects another record year as car buyers snap up new models such as the Q7 offroader and the TT Coupe roadster.
But the Ingolstadt-based manufacturer would not give a profit target in its latest market update yesterday.
The group needs Audi's good performance to continue, since the brand contributes the bulk of its profits.
The core Volkswagen's operation is expected to have only broken even last year.
Audi also pledged to bring its struggling sister brand, Seat back from the red by rolling out new models and derivatives. Seat is not part of Audi, but it comes under the Audi Brand Group headed by Audi chief executive Martin Winterkorn.
"We [Seat] will make an operating profit again in the foreseeable future and contribute clearly positive earnings at the latest in 2008," Andreas Schleef, Audi management board member and Seat chief executive said.
Audi's pretax profits grew by 14.6 per cent to 1.31 billion euros (£897 million) in 2005.
Revenue rose 8.5 per cent to 26.59 billion euros (£18.2 billion), yielding a profit margin of 4.9 per cent before tax versus 4.7 per cent a year earlier.
"No brand will grow like Audi in the near future," Mr Winterkorn said in a statement.
"We are planning to sell significantly more vehicles in 2006 than in the record year 2005."
