Every few months, a story comes out that says Mazda is imminently developing a new RX-7 and it will be on sale within two years. Every single time, people get intensely excited about the prospect of a rotary-powered halo car from the Japanese brand. And every single time, two years pass and there is no new RX-7.
This time, development to "bring the technology up to the standards of contemporary piston engines." This isn't necessarily a surprise, the rotary engine is Mazda's calling card, it's what made the brand unique for years.
But it also isn't an engine that is the best solution right now. Mazda would love to put the engine back into production, but there's no guarantee that'll ever happen unless they get it right.
The jump from developing that engine to Mazda could very likely have a new rotary sports car by 2017 is a pretty big one. Yes, that is the 40th anniversary of the RX-7 and would be a good time to bring one out, but we've been let down by promises of a new RX-7 too many times to actually get our hopes up.
If it happens, great, but for now, we'll sit quietly and hope.
