If, like us, you too have been drooling over the leaked patents of a baby Honda NSX from several months ago, good news, we have some news to share.

First believed to pack a Honda 2.0 litre VTEC turbo engine from the Civic Type R and a three-motor hybrid system that would give the baby NSX/S 2000 successor a healthy 400 hp total system output, a new report by Auto Express suggests that stricter emissions regulations may see Honda tone down the offering to a 1.5 litre VTEC turbo instead.

A source from within the Japanese car manufacturer is believed to have spilt the insider info to the British publication – the source also confirmed that, just like the NSX supercar itself, the new compact sports car will still be going ahead with hybrid power.

The 1.5 litre four-pot VTEC turbo is rumoured to be sourced from the 10th-gen Civic, and rather than the 400 hp quoted earlier, AE reports that the new sports car will instead be good for a total system output of around 300 hp, squeezing more life out of the original 174 hp available to the regular road-going Civic.

This should give the new baby NSX a power output similar to that of the 306 hp available in the latest-gen Civic Type R and its 2.0 litre VTEC turbo four. The mid-mounted engine is expected to power the rear wheels, while the use of electric motors for the front and rear axles will give this car an all-wheel drive configuration.

The new compact sportscar is expected to be revealed in full production form sometime in 2018, and will contend directly against the likes of the Porsche Cayman and the Alfa Romeo 4C. Only a coupe bodystyle is rumoured to be available for it, while its development will heavily involve help from McLaren and Honda’s F1 programmes.
