Fans of the 86 listen up. Rumour has it that Toyota is preparing a power boost for its popular 86 sports coupe.

The Japanese brand has teased numerous concepts of its two-door cult car with upgraded engines, including a supercharged TRD version (above) built in the U.S.A and a twin-charged version (below) created by its in-house skunkworks Gazoo Racing.

But those were designed to showcase the ability for aftermarket tuners and were not really suitable for mainstream production.

Now, the Chief Engineer of the 86, Tetsuya Tada, has finally admitted that his team is developing a number of ways to increase performance of the showroom version - one of which will definitely make it to production when the 86 receives its mid-life upgrade in 2015.

"I hope to make an engine upgrade at least one time with this car. We have already tried all possibilities and there are several types of 86 prototypes at the Toyota proving ground now; one is a turbocharger, one is bigger displacement and the other is a special hybrid system," said Tada.

Tada did not divulge any further details, but inside sources claimed that the most likely option is an increase in displacement, bumping the 2.0-litre horizontally opposed engine up to a 2.5-litre and increasing power from 200bhp to around 260bhp.

It is understood that this option would be the most cost-effective solution, which not only maintains the integrity of the lightweight concept but prevents placing additional stress on the drivetrain that a turbo charger would, or the complexity and weight penalty of a hybrid system.

However, both alternatives are not being tested in vain, as they are likely to be introduced on the next generation 86.

Either way, it is almost certain that the hybrid system Toyota is currently working on will make its way into the next generation 86. However, it is unlikely to be a conventional and heavy battery pack but rather a road-going development of the super capacitor system employed in its Le Mans sportscar racers, which are not only smaller and lighter but can store and deliver energy quicker for rapid bursts of acceleration.

Come on Toyota! We certainly hope to see a more powerful 86.
