Stadler also provided the strongest hint to date that Audi intends to add to its crossover lineup beyond the already-confirmed Q8 large crossover, Q1 and battery-electric crossover based on the e-tron quattro concept shown in September at the Frankfurt auto show.
Asked if Audi would add a Q4 and Q6, Stadler said, "I would not say no."
Stadler said Audi has been spared from cost cuts stemming from the diesel crisis, unlike the VW brand.
"Of course we are looking to each dollar and euro, but there is no deep cut because of diesel," Stadler said.
Audi is working out its own diesel violations with its 3.0-liter V-6 engine that powers some of its larger sedans and crossovers. Stadler said Audi has submitted a "package of solutions" to regulators for the engine and is awaiting feedback and approval from the California Air Resources Board and EPA.
"We are in very constructive and good discussions," Stadler said. "We believe we can start pretty early with the quick fix, and hopefully then for us it's done. But of course we have to discuss and keep contact with the authorities. That's for sure."
Keogh said Audi will soon announce its own goodwill program for affected diesel owners similar to the $1,000 gift-card and dealership credit package that VW launched in December.
Yet so far, Audi has yet to feel as much of an impact as the VW brand, Keogh and Stadler said.
"If you look at the traditional business metrics" such as Audi's record sales, loyalty and brand impact, "it has managed quite well," Keogh said. "But -- I think I know Mr. Stadler feels this way -- any time we upset one customer, it's a problem and we have to make the thing right, which we will do."
