The 12 other people on here trying to bad mouth Volvo have never owned one. I am on my second Volvo XC70, and still have my first XC70 and can say these are literally the best car every built for safety and reliability. Actually giving my wife my 2012 XC70 as her Volkswagen Golf Sportwagen has been nothing but issues that has had it go to the dealership to be fix. It’s a 2018 with only 13,885 miles on it. Really a shame, as it’s a fully loaded SEL, but sadly it’s one of the cars made in the USA and know this is why the quality has been so bad. That Golf Sportwagen was are fourth Volkswagen and last. After my Passat Sportwagen blew its engine due to a known issue I switched to Volvo and am glad I did. Now my wife is too as she will have my XC70 till she’s ready for a newer Volvo. Her dad has also switched to Volvo after being a Subaru owner for many years. We all know that nothing compares to a Volvo.
so that's why most Volvo crashes are crash tests
Volvo is the car of the future
Coming future cars must be like these :
HYDROGEN AS BATTERIES : HYDROGEN BATTERIES. Electric vehicles must switch to use hydrogen batteries instead of chemical batteries.
People often think about hydrogen as fuel, but many forget that hydrogen is not only a fuel, but also very good battery, too.
1/ The fundamental science dictates essential truth of all chemical batteries :
if a chemical energy storing mechanism is charged as quickly as producing hydrogen, then this mechanism PRACTICALLY CANNOT HAVE BETTER ENERGY CONVERSION RATIO THAN ELECTROLYSIS PROCESS. Besides, it is possible to setup and adjust electrolysis reaction speed (for example slow down speed) to reach energy conversion ratio of electrolysis better than any chemical batteries. The best one of all possible chemical batteries in AEROBIC earth conditions is HYDROGEN BATTERY. All revolutions of chemical batteries, lithium batteries, LFP batteries, LTO batteries, graphene batteries .. are for reaching to the features of hydrogen batteries.
2/ New concept : hydrogen battery = (fuel cell + hydrogen storage object).
The most simple hydrogen battery = 1 fuel cell + 1 compressed hydrogen balloon 300bar, can easily beat best lithium batteries by all features : more capacity, more power, less weight, forever lifespand, no degradation, charging in 5 minutes, same or better energy conversion ratio, but just noremarkable bigger volume sized than lithium batteries.
3/ So just equip electric vehicles with hydrogen batteries instead of chemical batteries. And equip hydrogen filling stations with mobile electrolysers to produce compressed hydrogen 300+ bar on site from electrical outlets. Electrolysing hydrogen filling stations (hydrogen battery charging stations) can run electrolysers from electrical outlets to produce liquid hydrogen on site, to avoid suddenly leap change requirements for big number of already existing current liquid hydrogen cars in the markets. But liquid hydrogen has low energy conversion ratio. For now and near future, compressed hydrogen (produced on site) is more versatile for various applications.
(Additionally envisagedly, owners of ANY SMALL COMPRESSED HYDROGEN MOBILITY VEHICLES/ROBOTS/DEVICES can buy small mobile household electrolysers to recharge hydrogen batteries at home at night/any times).
4/ Example and comparison : hydrogen cars vs battery cars, hydrogen batteries vs chemical batteries :
The old approach sets high H2 cost because : they pay for making H2, then they pay much for converting H2 to liquid H2, then they pay much for transporting liquid H2 by trucks (complex safety trucks, and very small weight of liquid H2 on every trucks), then thay pay for keeping cryogen conditions to store liquid H2.
But in new approach of ‘electrolysing hydrogen filling station” : you use electricity from electrical outlets at electrolysing hydrogen filling stations to run electrolysers to produce compressed hydrogen 300+bar on site. So you pay only for electricity and water ofcourse. No other fees. No complex cryogen equipments.
Compare : hydrogen batteries vs lithium batteries in the approach of “electrolysing hydrogen filling station” :
4.1/ Grid transmission loss : hydrogen battery charging and lithium battery charging onsite cause same grid transmission losses.
Conclusion : Equal.
4.2/ Energy conversion ratio in charging : (electric energy -> chemical energy)
Electrolysers in quick mode (very high electrolysis reaction speed) have energy conversion ratio about 70%. Lithium batteries quick charging has energy conversion ratio about 60-70%.
Electrolysers in slow mode (small electrolysis reaction speed) have energy conversion ratio 90%. Lithium batteries slow charging has energy conversion ratio 90%.
Conclusion : electrolysers win, because of the ability of flexible modes of scheduling and functioning to reach higher energy conversion ratio.
4.3/ Energy conversion ratio in performance : (chemical energy -> electric energy)
Fuel cell has energy conversion ratio about 75+% in mode of intensive power performance (when require delivering much walt/seconds), energy loss in form of heat. Lithium batteries have energy conversion ratio about 70-% in mode of intensive power performance (when require delivering much walt/seconds), energy loss in form of heat.
Fuel cell has energy conversion ratio about 85+% in mode of nointensive power performance (when require delivering less walt/seconds), energy loss in form of heat. Lithium batteries have energy conversion ratio about 95-% in mode of nointensive power performance (when require delivering less walt/seconds), energy loss in form of heat.
Conclusion : Equal.
4.4/ Energy loss in energy packing compressing process :
Hydrogen battery using compressed H2 300bar cause about 3-5% energy loss for compression. But hydrogen battery weight is very small.
Lithium battery loses 0 energy in compression. But lithium battery weight IS INHERENTLY HIGH.
That means you always need to transport noneccessary lithium battery heavy weights on your vehicles every seconds. -> The higher power category, the higher loss with lithium batteries. The longer range, the higher loss with lithium batteries.
Conclusion : hydrogen batteries win with big advantages
4.5/ Lifespan :
Hydrogen batteries have practically forever life span.
Lithium batteries have lifespan about 3 years. Some good ones have 5 years. Other modern modified lithium batteries have more lifespan but smaller capacities. But all of them degrade every year.
Conclusion : hydrogen batteries win.
4.6/ Influence of environment temperature :
Hydrogen batteries never fear environment temperatures.
Lithium batteries fear environment temperature. Even in some seasons you can not or your ineffectively use lithium batteries.
Conclusion : hydrogen batteries win.
4.7/ Charging time :
Hydrogen batteries : load compressed Hydrogen 300+bar or exchange compressed hydrogen canisters 300 bar in 3-5 minutes.
But you must waste minimal 30 minutes for nofull charging lithium batteries, and often you must waste some money for paying some unnecessary things in fool waiting times too. -> waste time + waste money.
Conclusion : hydrogen batteries win.
4.8/ Synchronyze with grid supplying schedules :
Electrolysing hydrogen filling stations can easily pick up flexible schedules to run electrolysers in tandem with grid supplying schedules. So Electrolysing hydrogen filling stations can pick up right hours of day for incentives electrical tarif. Nets of electrolysing hydrogen filling stations ideally use intermitten clean energy/renewable energy.
But electric charging stations can not pick up times. High power electric charging stations terribly conflict with intermitten shedules of clean energy/renewable energy. The more higher power electric charging station in quick charging mode, the more terribly it conflicts with intermitten energy supply schedules of clean energy/renewable energy.
Conclusion : hydrogen batteries win.
FINAL NATURE TRUTH VERDICT : HYDROGEN CARS WIN MANYFOLD AGAINST BATTERY CARS.
Just need to make right approach, and right choice
The lidar live view reminds me of Scanner Sombre
C40 is even more beautiful than XC40.

Why not let the driver keep their eyes open and concentrate on the traffic and not the iPhone. All these gadgets cost a lot of money and can malfunction.
That is a good idea to make a car that won*t cause collisions, how about the other people who cause it, how can you make the roads safer for everybody, one thing is that you will not cause a collision but the other person, how can you prevent them from causing a cllision
Got to watch a lot of XC 60 Model Year 2022 owner review videos .. seems like, Volvo has removed Drive mode selection wheel, removed Pilot Assist invocation from the steering, Four Zone Climate control not working if the front AC vents are not working, Music controls on the steering wheel not able to stop / pause the music ... these are some of the know issues !! Truley disappointed. Why on earth Volvo release such a buggy product to market ?
😂
So what are you doing to make your cars more exciting so people don't fall asleep behind the wheel from boredom?
Lol...aww I love my Volvo and it has some pep in its step when in dynamic mode!
❤❤❤❤
