Just watched this Hennessy video: They claim 1,000 HP crank & 840 RWHP which equates to 16% drivetrain loss. Don't know if auto or manual though.

Wow that is really low. How did you calculate those numbers?

Ok thanks. Using the 620 RWHP number and assuming 17% drivetrain loss, the crank HP is 747. Assuming 25% drivetrain loss, the crank HP is 827. Additionally, if we assume the published 668 crank HP is correct AND the 620 RWHP is accurate, this equates to only a 7.2% drivetrain loss which, in...

Yes but RWHP results I have seen are all over the map, ranging from 550 to about 630. Where can I find the results you mention?

... but I was pleased to see this on my new, 1,000-miles-on-odometer, 6 speed blackwing. I alternated between cruise control and snow/ice mode. Flat Florida road. Tip: if you are ever on a boring highway and just want to get the best milage possible at whatever speed (and don't want to use...

... you actually read the manual that came with your new car. However, I discovered there is storage for a compact umbrella in the driver and passenger doors. Pretty cool. What little-known facts have others discovered by reading the manual?

I was hoping that was the case. Thanks all.

Hi. Proud new owner of a 2023 CT5 V Blackwing 6 speed here. I have only had the car for 2 weeks so we are still getting to know each other. Just got out of 4500 rpm jail yesterday. Are the various exhaust settings purely acoustic changes or is the exhaust system actually less restrictive at...
