Mercedes-Benz has no plans to increase its stake in Aston Martin at present, according to Daimler chief Dieter Zetsche.

The two car companies forged a technical partnership last year that resulted in Daimler owning five percent of non-voting shares in Aston Martin.

Speaking at the Paris Motor Show, Zetsche said the current five percent stake Mercedes has in Aston is ideal because it “would not be in Aston’s interests to be incorporated into a big corporate organisation, as it would include risk”.

He added: “Aston is only 4000 units a year so there is also a danger we would be distracted from our core business. The deal is a perfect fit for both brands as it allows Aston to remain independent but also benefit from outside technology.

“There are no plans to increase our stake or take over.”

Zetsche also welcomed the arrival of Andy Palmer from Nissan to head Aston. “I regret Andy Palmer leaving Nissan as he was very positive to work with for us, but as he’s left I welcome him to Aston and look forward to future co-operation.”

Zetsche also revealed that the imminent return of the Maybach was likely to see the badge used in a similar way to Mercedes-AMG meaning super-luxury versions of the S-class could become Mercedes-Maybach models.

He also ruled out a Mini or Fiat 500-style expansion of the Smart brand, saying Smart’s expansion was more likely to come from getting involved in more urban mobility and car sharing schemes.

“I don’t see a range like Mini for Smart,” he said. “Smart is not an SUV brand.”
