Butschek, the Airbus former COO, was appointed to lead the home-grown auto major in January last year by ousted Tata Sons chairman Cyrus Mistry.
There has been speculations over his continuation after the change of guard at Tata Sons, with some high-profile appointments by Mistry, including Rakesh Sarna of IHCL, leaving the Tata Group.
"The fact that I was recruited by the previous Tata Sons leadership has nothing to do with my loyalty to Tata Sons and Tata Motors," Guenter told PTI here.
He said his experience in "functional, international and in particular turnaround experience was considered a key requirement at that point of time of Tata Motors".

Calling it speculation, Butschek said, "People actually read between the lines where there's nothing available between the lines."
He added: "I am aware of these rumours and I find these rumours extremely annoying. Last week, I saw speculations, and I was even linked to the Infosys story."
He felt that he has not seen any change in terms of the changed agenda of Tata Motors under the new Chairman N Chandrasekaran.
Reiterating that he is looking forward to his tenure in Tata Motors, Butschek said, "It (turnaround) makes the journey even more exciting. It helps accelerate the changed management process at Tata Motors."
Bullish on the company's future, he said: "I do believe if we can get Tata Motors' backbone, the CV, in particular M&HCV, back on track, then we can unlock a lot of potential of this organisation, which I consider as an extremely exciting opportunity and I would love to be part of it."
