[EX Q]: Germany's Audi has abandoned plans to sell its Italian motorcycle brand Ducati  its chief executive Rupert Stadler said  in a sign of confidence that the carmaker expects to be able to carry the costs of its transformation.
Steps to reduce costs by 10 billion euros ($11.8 billion)  cut red tape and deepen ties with fellow Volkswagen-owned brand Porsche are "gradually increasing our financial and organizational leeway for the strategic realignment " chief executive  Rupert Stadler  told reporters.
There is  therefore  no economic need to sell Ducati   Stadler  said. Volkswagen asked banks to evaluate options for Ducati and transmissions maker Renk earlier this year as seeks to become more nimble in its shift towards electric and self-driving cars following its diesel emissions cheating scandal.
"I can assure you that Ducati belongs to the Audi family " said  Stadler . "Ducati is the perfect implementation of our premium philosophy in the world of motorbikes."
While pushing the costly shift to zero-emissions and autonomous technologies  holding on to the profitable Ducati division and the lucrative Lamborghini brand has become more important   Stadler  said.
"Looking after a premium bouquet is as difficult as the work of a gardener "  Stadler  said. "Therefore I am pleased with every new flower  with every promising new branch " he added  predicting Lamborghini's sales would double on the back of its new sport-utility vehicle.
Separately   Stadler  said Audi will spend nearly half a billion euros over the next eight years on training staff for the digital age  with steps to develop as well as hire experts such as automotive app-designers and car robotics specialists.

JERSEY CITY  New Jersey (Reuters)  - Tiger Woods  said  he  was âoptimisticâ about  his  golfing future while at the same time publicly acknowledging what has been obvious for some time  that  he  might never return to competitive golf.
The American former world number one won the last of  his  14 major titles in 2008 and the 41-year-old has only played six competitive rounds in the past two years while trying to recover from multiple back surgeries.
âYeah  definitely. I donât know what my future holds for me â  he  said on Wednesday on the eve of the Presidents Cup when asked whether there was a scenario that would not allow  him  to compete again.
âI donât know what 100 percent (healthy) means after eight surgeries  but Iâll try and get as close as I can to that number â  Woods  added.
 Woods  was peppered with questions during a news conference with his three assistant Presidents Cup captains and the four International assistants  who often looked bored at the focus stayed on the second most prolific major champion of all time.

 Woods  seemed destined to become the most prolific major winner of all time when he won the 2008 U.S. Open  moving within four titles of the record of 18 held by Jack Nicklaus.
