PARIS -- PSA Group plans to sign a $50 billion merger deal with Fiat Chrysler Automobiles this year, a source with direct knowledge of PSA's thinking said on Friday, brushing off concerns over a shock lawsuit filed by General Motors this week.
The merger is set to create the world's fourth-largest automaker and give the new entity the scale to meet technological and regulatory challenges that are troubling automakers globally.
FCA has already said the lawsuit brought by GM on Wednesday was "meritless."
The source, who spoke on condition of anonymity, said PSA remained focused on the merger talks, and intended to sign a memorandum of understanding on the deal this December, as scheduled.
FCA also expressed confidence in reaching a binding merger deal with PSA by the end of this year.
In the lawsuit, GM alleges FCA bribed UAW officials over years to corrupt the bargaining process and gain advantages, costing GM billions of dollars.
FCA said the suit, seeking substantial damages, appeared intended to disrupt its merger plan with PSA.
