Mazda 16X rotary engine two years away, will arrive in all-new model

Mazda Renesis

We last reported on Mazda‘s next-generation rotary engine project in June of 2012 when the automaker built its last Renesis-powered RX-8, but rumors of this new engine’s development had been around way before that final car left the production line in Japan, last year.

We now have enthusiastic confirmation that this next-gen rotary engine is really and truly going forward. It is still referred to as 16X and has several priorities. First is to lower fuel consumption compared to the RX-8′s engine, while still making gains in terms of performance. The second is to reduce the burning of oil that was happening at the highest revs. And the third and final priority, and perhaps most key for enthusiasts, is to give the powertrain a big torque upgrade.

What we were told by a Mazda USA insider (while we are all here together at the festivities in Monterey) is that the first application of the new 16X engine will be happening in two years’ time in an as yet undisclosed new model. Oh, the mind races to our eternal Mazda wish list…

Mazda piggybacks on Ford Escape recall with 215,000 Tribute models of its own

A day after Ford issued a recall of 485,000 Escape crossovers from its 2001-2004 model years, Mazda has reportedly issued its own for the 215,000 examples of its Tribute, the Escape’s mechanical twin. While it’s the same engine configuration being recalled, the 3.0-liter V6 with cruise control, there is a difference in the recalls: Mazda is recalling 2002-2006 and 2008 model year Tributes, three more years of production than the Escape (the Tribute wasn’t made in 2007).

The problem is a lack of clearance between the engine cover and the cruise control cable, which can prevent the driver from letting off the throttle if the cruise control is on. The situation was caused by a repair for a different recall in 2005. Mazda says the engine cover is similar enough to warrant inclusion for all years of production it has cited. It isn’t known yet if Ford will expand its own recall.

Mazda rumored to use laser-ignition for next-gen rotary

Autocar is reporting that the next-generation rotary engine from Mazda may turn to a laser ignition system instead of traditional spark plugs. The report supposedly comes straight from the mouth of a shadowy senior engineer within the program. Mazda has been hard at work on the 16X Renesis rotary since around 2007 and the engine has seen quite a few evolutions over the intervening years. Autocar says that the design has seen displacement swell from 1.3 liters to 1.6 liters and that at least some parts of the engine have been designed to be made from aluminum to further reduce weight.

The work is in an effort to get the rotary to be more fuel efficient and provide more torque, the latter not usually being a chief attribute of this type of engine. According to Autocar, using a high-temperature laser ignition system would allow engineers to tune the Wankel to run leaner than systems that use a conventional spark plug. It would also reportedly allow the engine control module to more accurately adjust and monitor timing.
