Toyota GT86Toyota

Toyota is expected to introduce a lighter, track-biased version of its acclaimed GT86 sports car next year, Autocar reports.

A prototype version of the new model has been spotted in testing at Germany's Nurburgring racetrack, wearing a lightweight carbon fibre bonnet as well as a new roof, boot-lid and a much larger rear spoiler.

The additions are likely to be an attempt to reduce the current models' 1,257kg kerb weight, to maximise the performance potential of the GT86's 197bhp 2.0-litre flat-four engine.

Indeed, no engine upgrades are expected with this new model, with many of the alterations focusing on the suspension for a sharper on-track driving experience. So expect an unaltered 7.6-second 0-62mph time and a top speed of around 140mph.

However, Toyota has been cited as saying that the forthcoming face-lifted GT86 may come with a more powerful engine, with a modified intake system and sports exhaust.

The new lightweight GT86 could be introduced as a flagship, limited-run special edition aimed at enthusiast drivers. If so, expect a price tag much higher than the current car's top asking price of £33,110.

The current GT86 has enjoyed fettling for the 2015 model year, and now comes with firmer front suspension and revisions to the rear shock absorbers. Interior quality is also improved, with the car now sporting real carbon fibre trim.
