Audi does name registrations for future model

A series of recent trademark applications has provided some insight into Audi's potential global line-up.

While many of the trademarks may simply be in order to protect the company's intellectual property, they appear to correlate with previously mentioned models and concepts.

The most notable is the registration of 'SQ2', which would presumably be a high-performance version that could be called the Q2. Audi has previously previewed a concept version of such a car, in the form of the Crosslane Coupé, in 2012.

In a similar vein, 'SQ4' - based on the planned rival to the Range Rover Evoque, the Q4 - has been trademarked.

Audi has also seemingly confirmed its plans to expand its SUV line-up further with an application to trademark 'Q9', tallying with reports of of a large luxury model that would sit above the current Audi Q7.

The 'f-tron' name has also been trademarked, suggesting that Audi may be considering a series production car that utilises fuel cell power.

Wolfgang Dürheimer, Audi's ex-technical chief, had previously told Autocar that the company had been developing a fuel cell-powered Audi A7.

The manufacturer currently uses the 'tron' moniker on its vehicles that utilise what it claims to be 'sustainable technology'. Currently, e-tron and g-tron models are offered. These make use of electric, either solely or in hybrid powertrains, and compressed natural gas respectively.
