It has been more than eight years since the current Nissan 370Z, shown above, went on sale, but Nissan's legendary Z-car soon will get its long-awaited redesign. The first major step will be taken at the Tokyo auto show this fall, where Nissan will reveal the next-generation Z concept, a preview of the production car said to offer several potent powertrains.

It is expected that the new Z concept and production car will have similar proportions to the outgoing coupe. The Z will also adopt an edgier styling language, including a gaping front end that takes cues from the latest GT-R facelift, and will ride on a shorter wheelbase courtesy of the Infiniti Q60's FR-L platform.

Of the three powertrains on offer, the flagship twin-turbocharged 3.0-liter V-6, borrowed from the Infiniti Q60 Red Sport, is said to punch out a healthy 400 horsepower at 6400 rpm and 350 lb-ft of torque at 1600 rpm; it will be mated to a seven-speed dual-clutch automatic transmission. If this version lives up to those expectations, it could put the Nissan toe to toe with rivals such as Porsche's 718 Boxster S and BMW's M2.

In addition to the entry-level 3.0-liter V-6, generating 300 horsepower and 295 lb-ft, we also hear that Nissan is working on a hybridized model to be introduced later that could make the Z the most powerful in its class. It is expected to employ the same 3.0-liter V-6, teamed with a dual-clutch gearbox and an electric motor producing as much as 160 horses. One source told us that this model's total output could reach an eye-popping 500 horsepower. The new Z is expected to land in showrooms by 2019, with the base model priced in the low-$30,000 range and the twin-turbo nearing $50,000.
