If you want to get very technical and have some math/physics/engineering background, then you will find the Honda R&D Technical Review journal fascinating. Registration is required to download/view the articles, but the registration isn't onerous.

The current issue, Vol.29 No.1, https://www.hondarandd.jp/summary.php?sid=51&lang=en has quite a few articles on the CivicX, for example:
Vehicle Dynamics Performance Enhancing Technology for New CIVIC
Mikito KOBAYASHI态 Masaya YAMADA
Aerodynamic Development for High-speed Stability in New CIVIC
Susumu MASHIO态 Masayuki MINAGAWA
Advanced Technology for Interior Vibration Reduction for New CIVIC
Tsutomu MATSUBAYASHI态 Osamu MATSUDA
Advanced Technology for Road Noise Reduction for New CIVIC
Jun TSUTSUMI态 Hitoshi TAKATSU态 Atsuhiro YAMAZAKI
Broadly-applicable Adaptive Damper System without Use of Dedicated Sensors
Ryoma KANDA态 Yujiro NISHI态 Masaki IZAWA

Some articles from older issues:
New In-Line 4-Cylinder Gasoline Direct Injection Turbocharged Downsizing Engine
Koji NAKANO态 Yusuke WADA态 Mitsutaka JONO态 Shigeru NARIHIRO
Simulation of Oil Separating Behavior for Engine Breather System
Makoto HAGA态 Takumi KASAHARA
Development of Agile Handling Assist
Kazutaka OHMURA态Takeshi KOJIMA态Tomoyuki FUTAMURA

the adaptive damper technology is so cool - it's just such a shame they're using it for maintaining comfort rather than pushing performance higher

thanks for posting!

I was with the understanding that the 1.5 was not VTEC. But this article summary seems to imply that it is indeed VTEC:

"Two new models of in-line four-cylinder VTEC turbo engine have been developed as part of the cluster of new-generation power train technologies known as EARTH DREAMS TECHNOLOGY, which achieves a high-level balance between driving performance and fuel consumption. Both VTEC engines use high-tumble ports, valve timing control (dual VTC) of both intake and exhaust camshafts, multi-hole direct side injectors, and high-response turbochargers with attached electric waste gate actuator. With these technologies in common, the new engines successfully yield maximum thermal efficiency and power through cooperative control and turbocharging conditions based on combustion technology that uses high-tumble flow. The 1.5 L engine puts out the same 110 kW of maximum power as the 2.0 L naturally aspirated engine while increasing low- and medium-speed torque by a maximum of 30%. A vehicle with this engine installed achieved fuel consumption of 17 km/L in JC08 mode, which puts it at the top of the minivan class, and a 75% reduction relative to the level required by Japanese 2005 regulations for exhaust emissions. As a high-powered sport engine, the 2.0 L model achieves maximum output of 228 kW and maximum torque of 400 Nm. A vehicle with this engine installed achieved CO2 emissions of 170 g/km in European fuel economy mode and Euro 6b compliance."

Update: "Dual VTC was adopted for the 1.5 L type while the 2.0 L type additionally adopted VTEC on the exhaust side." Not to mention how this has been hashed out historically (et al.)

It all depends on how you define 'VTEC' vs. 'VTEC TURBO.' However, we all know Honda stopped calling the 1.5 a 'VTEC TURBO.'

In the article, it was stated "Dual VTC was adopted for the 1.5 L type while the 2.0 L type additionally adopted VTEC on the exhaust side." So the 1.5 isn't VTEC, the 2.0 is half-VTEC, and neither is VTEC YO :).
