they aren't adding another transmission in addition to the DCT, they are putting a torque converter or electric motor between the gas engine and the DCT. Why? well remember a DCT is a manual transmission with 2 clutches. One of the biggest complaints and issues with DCT's is shudder, jerks, etc. at a start. I guess people that are used to an automatic and never driven a stick are expecting a very smooth engagement, like you get with an auto and the same smooth shifts. That's pretty hard to do with a DCT under all conditions. Various mfg have had a slew of complaints and problems from customers on cars with DCT regarding shudder, jerks, harsh engagement from a start along with inconsistent shift engagement. And they have struggled to come up with solutions. Honda's solution seems to work well. with either the electric motor or torque converter along with a DTC they get the best advantages of an automatic for starting and the performance, low weight and economy advantages of the DTC. Of course it adds cost.But not with same motor besides why would they add another transmission in addition to a DCT? Is that a common practice with DCTs?
yes, like I said earlier in a post the honda 8 speed DCT in non hybrids has a torque converter. The ILX4 and TLX 4 cylinder have an 8 speed DCT with torque converter.Sir, why are you switching between topics? DCT coupling with electric models is fairly common at this time so no questions there.
Is Honda coupling a TC with a DCT in non Hybrid models?
