I sure would like to learn more about the ""Atkinson Cycle LAMBDA II 3.8L V6 GDI" engine.
3.8 liters is larger than the typical 3.5 liter V6 engine which I thought was limit for fuel efficiency reasons. But I do see that the KIA has decent fuel economy, AWD 19-24, 21mpg, which I attribute to the Atkinson Cycle of the engine. I have also read a little on the Atkinson cycle which I understand has been simplified in modern engines to variation of the variable valve timing (VVT) to mimic the essentials of the Atkinson cycle. I believe that the 2017+ Tacomas use this, as well as most hybrids. What was interesting was that since it is a function of the VVT that it in Tacoma it could be transitioned to the more powerful OTTO cycle, common to 4 cycle engines. Could this be KIA Economy vs Sport modes?!
Sure would like to learn if my speculation is correct and see more info, details, even hp torque curves for this engine. KIA website has no info, nor does Wikipedia offer much.
To be honest this is the one area of the car I am a little dissapointed in. The prototype idea of the hi performance hybrid was not ever realistic, but they touted this as a near luxury vehicle with a performance target closer to the 400hp mark. I would have really liked to see the Stinger's Twin Turbo V6 in this as an option on the higher end trims.
