I hope the 30%..would be on the bigger displacement "X" engine.
That'd be nice if they did a 2.5L version as well - 230 HP, 210 lbs-ft with fantastic mileage could get me back into FWD.

Also, read up on the chassis upgrades - 2019 Mazda3 Prototype First Drive: Fourth Gen's the Charmer - Motor Trend - hoping they didn't gain weight, but everything they describe that they did lights up the right spots in my brain.

Some updates on Mazda's engine roadmap at the Frankfurt Auto Show.
All Future Mazda Cars Will Be Electrified By 2035


- full range of vehicles to be electrified in one form or another (mild hybrid, plug-in hybrid, full electric) by 2035
- first mild hybrids due in two years
- HCCI coming out in 2019 (super clean gas engine) under the Skyactive X brand
- 2019 is also when we'll see their first zero emission car (with a rotary range extender)
- plug in hybrid to launch in 2021
- autonomous vehicles launching in 2025

We will likely see a 2.5L version, although initially the existing 2.5L will get pumped up in the CX-5 this fall to 194hp/190lb-ft due to some minor engine improvements. I expect the next 6 to get this engine until the 2.5L skyactiv-X is ready.

Ditto. I also hope that they'd keep the next 6, as lightweight as possible. At the current torque values of the 2.5L (185lbs-ft)..assuming at the low ball gain of 10%, we could see around 204lbs-ft. A high gain of 30%, that could possibly be 240lbs-ft. In real world driving (Los Angeles), torque matters to me most..than hp. If the FWD "X" Mazda6 disappoints me..surely, I'd go the opposite way, to RWD (the next Mustang GT or Camaro 1SS), also in a manual. We'll see.

Btw, I noticed you're from Grand Rapids. When I was up there in MI last Nov (be flying back, in two weeks actually..) driving upstate to Makinaw via the 75N..I only spotted I think around two GJ/GL Mazda6s that day. Seeing our rare cars, still always catches my attention. I love it's exclusivity (not to mention the fastback style, handling and fuel economy).

Well, from the couple articles I've read today it sounds like Mazda might have cracked this technology.

Iím sure itís there or at least pretty damn close-Iíd be curious to see the actual placement of the spark and what the stroke length would be compared with the conventional petrol engine
