The company had sold 6,461 units in the same period last year, Mercedes-Benz India said in a statement.
Commenting on the sales performance, Mercedes-Benz India Managing Director & CEO Eberhard Kern said: "The first three quarters of 2014 has been very satisfying for Mercedes-Benz given the tough market conditions the industry battled."
He further said: "We have launched eight new cars, sold more cars than ever before, expanded to newer markets, added newer customer base, connected with more customers through our brand connect programmes and offered more value to our customers."
The results of these initiatives have been an inclusive growth for the brand in India in the first three quarters, he added.
Mercedes-Benz India's SUV portfolio is on the highest growth path and witnessed an impressive growth rate of more than 100 per cent, the company said.
The popularity of the SUVs is closely followed by the compact cars. The compact portfolio which includes the A-Class and B-Class, witnessed a strong traction, it added.
The company's flagship model, the S-Class, continued its popularity run and remained sold out for the remaining year and the recently launched CLA 45 AMG was instrumental in adding new customers to the Mercedes-Benz brand fold.
The latest luxury SUV, the GLA-Class will be available for sale only from this month, it added.
