Mazda Unveils New Rotary Engine; RX-8 Replacement by 2010

Mazda has confirmed it’s working on an all-new rotary engine for 2010.

This second-generation Renesis rotary, with more power and less thirst than today’s unit (as found in the RX-8), is the star act in a new round of Mazda powertrain technologies unveiled last week at a business conference in Tokyo.

Mazda said it also plans to introduce a new automatic transmission with improved fuel efficiency and “performance comparable to that of a manual transmission” beginning in about 2010.

As it reaffirms its commitment to rotary technology, Mazda will also begin leasing a Premacy (Japan’s version of the Mazda 5) with a hydrogen rotary hybrid in 2008 and launch a full production model using this Mazda-designed system by 2010.

Further ahead, Mazda also has an all-new hydrogen rotary engine with power equivalent to a 3.0-liter gasoline engine and a range of some 250 miles under development.

This reaffirms previous reports that a redesign would come in early 2009 as a 2010 model – a two-seat coupe was once evaluated but deemed too expensive to develop for the incremental volume it would produce. With the Mazda Kabura concept also slated for 2010 – is this a hint towards how the future development of the RX-8 replacement would look like?
