Yep. In engineering terms the air mass measurement is feedforward; the oxygen sensor is feedback. The feedforward allows very rapid response to...
Nowadays the oxygen sensor does that job. It constantly looks at the exhaust and adjusts the mixture so that combustion is complete, no matter...
There are two aspects here - engine efficiency and vehicle efficiency. Normally aspirated engines do see higher fuel economy (and lower peak...
A few weeks ago I exchanged my 2017 Prime for a 2024 Prime. After looking for about a month, I finally found a Prime (in Nebraska no less) that...
Tried that. There's a light at the top of the hill. Starting from a red light with no power input, I hit a speed of 80mph before I chickened out...

Will try that thanks. Can't hurt.
I've had a 2017 Prime for 7 years now, and when I first got it the EV range was estimated at about 22 miles by the car. After driving it for a...
Good point, and I am indeed taking that into account. I have one of those that I use when I go to a destination that doesn't have charging and is...
