Mazda Successor to RX-7 and RX-8 Rumoured with 455hp Rotary Turbo
Reports suggest Mazda is preparing a new rotary sports car with a turbocharged engine producing around 455hp, targeting a 2017 launch to succeed the RX-7 and RX-8.
Mazda is reportedly working on a successor to its RX-7 and RX-8 sports cars, with sources indicating a turbocharged rotary engine developing approximately 455hp is in development. The new model is understood to be targeting a launch around 2017, according to reports from motoring.com.au.
The new sports car is said to ride on a heavily revised version of the RX-8’s platform. While the RX-8’s naturally aspirated rotary engine was known for its unique character, it also drew criticism for high fuel and oil consumption and lacklustre mid-range torque. Mazda is expected to apply its SkyActiv engineering approach to the new rotary, aiming to improve efficiency, reliability and driveability.
Rotary returns with turbocharging
The heart of the project is a new-generation rotary engine, reportedly paired with a turbocharger to deliver the 455hp output. This would place the car well above the last RX-8 in terms of performance, and in line with other high-powered sports coupes. The addition of turbocharging is intended to address the rotary’s traditional torque deficit and emissions challenges.
Mazda’s SkyActiv technologies, already rolled out across its mainstream models, are expected to play a role in the new rotary’s development. The goal is to resolve issues that have long affected rotary engines, including high oil and fuel consumption and limited torque at lower revs. Details on the specific SkyActiv innovations for the rotary have not been confirmed by Mazda at this stage.
Platform and technical direction
The platform for the new car is reported to be an extensively modified version of the RX-8’s chassis. While the RX-8 was praised for its handling, its engine reliability and efficiency issues limited its appeal. The successor is expected to retain a front-engine, rear-wheel-drive layout, continuing the RX tradition. No official details on weight, dimensions or transmission have been released.
Mazda has not officially confirmed the project or released technical specifications. However, the company has previously signalled an interest in reviving the rotary engine, as covered inMazda Pushes Ahead with Rotary Engine Revival Plans. Any production model will need to meet modern emissions and efficiency standards, a challenge for rotary technology.
What to expect next
With the RX-7 and RX-9 names protected and a high-output rotary turbo engine reportedly in development, Mazda appears committed to bringing a new sports car to market. The company has not confirmed a launch date or pricing, but reports suggest a debut could come as early as 2017 if development proceeds as planned.
