Next-gen sports car to morph into slinky CLA rival, likely with available hybrid and all-electric powertrains.

Audi has reportedly given a four-door version of its TT sports car the green light, with the new model to launch within the next 24 months.

Britain's Auto Express claims the 'Sportback' could be the only version of the next-generation TT available, drawing inspiration from the 2014 TT Sportback concept (pictured) shown at the Paris motor show of the same year.

The publication says the four- to six-year delay between the concept and a production version is largely down to the Volkswagen Group's extensive cost-cutting following the Dieselgate emissions scandal, which cancelled various projects across the group's brands including Audi.

However, the German marque's board has reportedly now finalised the project and given approval of the production model's design.

It's believed the four-door TT will be based on an updated version of the MQB platform that underpins the current TT along with other models like the A3 and Volkswagen Golf, meaning we can expect front- and all-wheel drive models, driven by small-capacity turbocharged petrol engines.

The new TT is also expected to offer electrified powertrains as well, including 48V mild-hybrid units, a plug-in hybrid, even a potential all-electric variant.

As for where such a model will sit in Audi's line-up, the TT Sportback would likely fill the 'small' four-door coupe role, slotting underneath the 'medium' A5 Sportback and the 'large' A7 Sportback, serving as the style-focused equivalent to the A3 range.
