Insideline.com writes that the future RX-7 will rely on a recently-revealed Renesis 16X rotary engine fitted on the Taiki concept which was unleashed at the Tokyo Auto Show back in 2007. As compared to the RX-8, which used a 654cc x 2 system, the 1.6-liter two-rotor engine is based on a 800cc x 2 architecture and is capable of developing 350 horsepower and 215 lb-ft of torque.
On the other hand, Mazda earlier this year upgraded the RX-8 in Japan, revising the equipment levels, pricing and introducing two new colors.
The standard equipment offered across the range now includes rain-sensing windshield wipers, auto-light system, water-repellent coating (on the front door windows and door mirrors) and Mazda’s advanced keyless entry and engine start system. There are two new body colors, Aluminum Metallic and Metropolitan Gray Mica, which raise the total number of exterior colors to seven.
Additionally, the RX-8 is now offered in a new base model codenamed Type G, powered by the same water-cooled in-line engines and mated to a 6-speed automatic transmission. This particular version is priced at 2,630,000 yen ($27,700) with all taxes included.
