With the reign of the Japanese sports car well and truly on track to make a return, new rivalries are appearing such as the new Honda NSX is to the Nissan GT-R.
The most recent and unique addition to this bitter rivalry is Nissan's new FF Hybrid sports car - with the Honda CR-Z squarely in its sights.
An entry-level coupe to slot into the Nissan range just below the FR, the 2+2 front-wheel drive FF coupe will feature a hybrid drivetrain, aiming to be both fuel efficient and a spirited drive.
It will be based on the existing Nissan 'B' platform as used on the Tiida, and follow on from new styling trademarks established on both the new Maxima and upcoming 370Z.
Lightweight aluminium panels are likely to be used extensively to keep weight below 1100kg, and its possible a flat bottom panel similar to that on the GT-R could be employed to improve aerodynamics and fuel efficiency.
It's expected the FF coupe will be powered by a revised hybrid version of the HR15DE 1.5-litre four cylinder engine mated to a 6-speed DSG gearbox.
