Kjell Gruner, chief executive of Porsche North America, said in an interview on Thursday that Porsche was planning to build on the success of all-electric models.

Gruner said it was seeking further investment in all-electric vehicles, plug-in hybrids and internal combustion engines.

Porsche's second-quarter earnings rose 55 per cent from a year earlier, Gruner said.

Kjell Gruner, chief executive of Porsche North America, said in an interview on Thursday that Porsche was planning to build on the success of all-electric models.

"in fact, the demand for all models is very high at the moment," Gruner said. " "We are satisfied with the demand for the Taycan (Porsche all-electric sports car), which accounts for about 15 per cent of our total sales. But the important thing is that the brand is strong and people like the customer experience. At the same time, we have a very strong product portfolio. "

Gruner also said Porsche's second-quarter earnings rose 55% from a year earlier.

Porsche is currently working with TeslaOther electric car makers, such as (Tesla), compete to dominate the electric vehicle market. Gruner said the three pillars of its powertrain strategy include future investments in all-electric vehicles, plug-in hybrids and internal combustion engines.

Porsche says sales of its all-electric Taycan, launched in 2019, are already equivalent to those of its iconic 911 model. According to Gruner, Taycan sales come from existing Porsche owners, customers from competing brands such as Audi, BMW and Mercedes-Benz, and other customers who want to include Porsche in their existing car range.

The former CEO Klaus Zellme of Porsche North America once said in an interview that Tesla owners were most interested in Taycan. It still accounts for a large part of Porsche's total revenue.

Gruner said that although Porsche always wants to sell one car less than the market demand, it is still trying to deliver the car on time. "We work very hard on production and procurement," Gruner said.
