The bespoke service allows customers to tailor their vehicles to their tastes by picking from a range of colours, trim finishes, materials and other cosmetic options.
A new 'Q Lounge Concept' is also being previewed, the aim being to allow customers to better visualise their personal creations. These lounges will later be offered in selected worldwide dealerships.
The Q by Aston Martin scheme even allows customers to commission one-off cars, such as the CC100 Speedster Concept.
General Manager of VIP and Q by Aston Martin Sales, Matthew Bennett, said: "What Q by Aston Martin adds to that already exciting process is the freedom to think beyond spec sheets and options lists.
"It challenges the designers and engineers here at Gaydon to use their talents to produce something truly exceptional, and unique."
The new models and Q scheme should serve to further improve Aston's sales in China, where has seen growing sales since the brand launched in the country in 2008.
Jenny Zheng, Aston Martin’s China Regional Director, said: “A confident expansion of the dealer network is continuing here in China.
"In the last few weeks alone we've had the grand openings of the Aston Martin Xi’an and Aston Martin Qingdao dealerships, and the addition of an impressive new downtown showroom for the important Beijing market.”
