Both magazines will feature a double-page spread advertorial with a bound-in four-page gatefold printed on heavyweight stock, giving Audi six pages in each magazine.
The key message of the campaign is to show the Audi as having style, attitude, inspiration, confidence and performance, as well as showing the car's new design. The ad shows an elegantly dressed woman posing with a hubcap.
Kris Oddy, product communications manager for Audi UK, said the deal enabled Audi to portray the Audi TT150 as an "extremely desirable fashion accessory".
She said: "Our aim was to launch an entry model for an iconic product in a subtle and sophisticated way."
The concept is the same in both magazines, but the ads have been shot to mirror the individual magazines' style.
Emma Hudson, SouthBank Solutions' group advertising promotions director, said: "We worked closely with Audi and each editorial team to ensure we matched the brand objectives of Audi with the brand values of In Style and Marie Claire."
The deal was negotiated between two of IPC Advertising's divisions -- IPC Southbank Solutions and IPC Corporate Development -- and Audi's media agency MediaCom.
Stuart Robertson, IPC Advertising's business development director, said: "Pairing-up the Audi TT with Marie Clare and In Style, brands that really complement its iconic image, have worked extremely well to drive our client's objectives."
