People care for the same reason that people have been obsessing about drag strip times and fractions of seconds since at least the beginning of the ICE hot-rod era. It's fun fuel for daydreams about cars and what cars can do to make us feel more accomplished and generally cooler all around.Why does anyone care that the Tesla can do 1/4 mile in 300 mS less that the Lucid?
It doesn’t spell the end until you can have high performance and range altogether.Why does anyone care that the Tesla can do 1/4 mile in 300 mS less that the Lucid? That aside, these are numbers derived from pre-production cars.
According to a recent Teslarati article the significant fact is that there are two BEV that are going to deliver 9 second 1/4 mile times and that this spells the end of ICE high performance cars.
Okay, then.As it is a Rivian forum I guess I think that discussion of Lucid's 1/4 mile times or Tesla's active suspension should be somehow in comparison to Rivians.
500 miles doesn’t equal 500 miles of travel. My f250 ran the quarter mile, albeit not as fast as in the 9s but in the 10s and had a range of 500 miles. My meaning is the amount of energy a BEV would lose compared to fuel.Which leads to the obvious question: what are the ranges of the ICE cars which have 1/4 mile times near 9 seconds? Both the electric ones are 500 mile cars.
Your going to have to explain that one a bit.My meaning is the amount of energy a BEV would lose compared to fuel.
It was not my desire to have to correct you again on your misconceptions about engineering terminology. Once should be enough and cannot possibly be of any interest to the other readers. If you want to understand what these terms mean you can look them up. Please don't wast my time, your time or anyone elses time (not that I think anyone else is reading this) by posting again that the Tesla system is not active. You will get the same answer.Tesla does not have an active suspension. It has as adaptive suspension, which is the term it displays on its in-car screen.
The Tesla system does not, as I understand it, raise the wheel but it can lower it. Thus it hasn't as many degrees of freedom as the Mercedes system but as air is pumped into that cylinder it is active control. By definitionSome Mercedes cars use an active suspension. Here is a description of how it works:
"The system uses two small cameras behind the windshield
The Mercedes active suspension can actually raise and lower each ...
It doesn't have to do that but the way it would if it needed to would be by use of the cameras or by predictive filtering (Kalman filter?) of the accelerometer inputs. The Tesla does not move the wheel before it encounters the surface irregularity. It just tires to make sure that the energy coupled into the wheel does not get coupled into the car itself. See the previous posts for an explanation of how that works.Could you point out how Tesla gets its inputs from the road ahead for its active suspension to go into action and move the wheel before it encounters the surface irregularity?
I'm not understanding. My X is rated for 351 miles on a full battery charge and I get 351 miles plus a bit. The Lucid and Plaid S are rated 500 miles. I would expect to get 500 miles on a full charge from each of them given where and how I drive.500 miles doesn’t equal 500 miles of travel. My f250 ran the quarter mile, albeit not as fast as in the 9s but in the 10s and had a range of 500 miles. My meaning is the amount of energy a BEV would lose compared to fuel.
Trying to fit marketing terms into binary categories is fraught with error. The latest Tesla Model S suspension is, from what I've read (I haven't ridden is a Tesla since the Roadster long ago), a hydraulic damping with electrically modulated valves, which they like to call "active damping". That's not the same as an "active suspension", which doesn't have an SAE definition I could casually find, so it's going to be misused and misinterpreted (just look at the various understandings of self driving levels, which *do* have SAE definitions). But, the term active suspension is generally used with systems that can move the wheel in either direction on demand and up to some limiting speed (due to hydraulic and control reaction time). But, I've also read the Cybertruck is supposedly going to have an active suspension.Active means not passive. Any device which takes power from a source other than the system itself to function is an active device. The servo in the Tesla takes power from a reservoir of compressed air (maintained by a motor) and is, therfore, an active system.
The Tesla system does not, as I understand it, raise the wheel but it can lower it. Thus it hasn't as many degrees of freedom as the Mercedes system but as air is pumped into that cylinder it is active control. By definition
No appreciable difference (a single 1/4 mile pass takes only a percentage of the total charge/gas for either vehicle). Your mpg will be very low or your wH/mi very high - but only for a 1/4 mile. In either case the "lost" range will be much higher than a 1/4 mile, but only a relatively small percentage of the overall range of a 500 mile vehicle. Since I don't know of any 500 mile range sub 10 second ICE vehicles, and exact number is hard to define.
