Let me tell you about " state of the art"
My Lexus LS is very dependable and amazing to drive in the snow
My BMW 750 I (M sport) X drive is a nightmare to maintain as this car needs 2 batteries, special run flat tires at $432 EACH and requires an oil change every 5,000 miles @$245
Lexus dealer charged me $100 and said 10,000 miles is ok ( I never go past 6,000)
The electronics on the BMW are very complex .
To change the cabin filter on the Lexus takes 2 minutes NO tools and my wife changed it and we bought OEM parts off Amazon under $10
The BMW the dealer wanted over $300 to remove the screws to gain access $40 for the filter
The BMW needed a shock absorber after hitting a pot hole $2,800 and it took 4 WEEKS to get the part
The Lexus 2011 Only needed the battery and tires replaced and parts are readily available over night if needed
When the BMW had the batteries replaced one under the hood the other in the trunk they had to be programed to the car
The Lexus battery took 10 minutes to replace
Twin turbo 93 Octane to get the right performance and this car cost over $20,000 more then the Lexus ($87,600) BMW $123,000 +
Consider buying an electric vehicle (EV)- for most the maintenance is essentially reduced to tires & windshield wipers.
If you're into road trips, favor quick-charging speed over range. (The Mustang EV has reasonable max range, but the last 20% for topping it up is excruciating.)
In short years there will be ample competition from BYD, Xiaopeng, Nio and Great Wall (among others), all of which are way ahead of all US, European, Japanese, or Korean manufactures, with the exception of Tesla. VW group may have grown a leg to stand on against the tsunami of Chinese competition within the next few years, but nobody else does. Despite lots of pre-orders, the limited production runs of gold plated pickups & SUVs isn't going to be enough to save GM or Ford, though one of those two might survive. Ford doesn't have good enough credit to make the required investments at cheap enough bond rates- stay tuned. (They have big EV plans, but might not be able to finance them.) Toyota (ergo Lexus) seems to be betting their future on hybrids- a very
bad bet indeed, IMHO, though they are going to be selling a battery EV in 2023 (?), that car is going to be built by BYD with BYD's technology. GM is part of a consortium with a hot selling EV in China (the Wuling Mini), but it's a car more targeted for the developing world, not the US market.
BYD's blade battery tech with (extremely fast to full 100% LFP battery chemistry) and 800V system will be very attractive for those running road trips. The newer "Ocean" series with that is only starting to roll out the first was the EA1 Dolphin (released only a couple of months ago), was a Toyota-Corolla sized car (but nicer than a Corolla) starting at only $15K USD. The more upscale "Seal" has been spotted on the street, but should be out there before the summer. Xiaopeng's P5 is a Camry-sized car (but much nicer than a Camry) in the mid $20Ks USD. Nio's offerings are even nicer- something of a luxury brand in China, competing remarkably well against Tesla in a similar luxury & technology class. All of these cars will be selling in Europe either this year or next.
Unless they partner with a better developed EV company BMW & Mercedes pretty much won't be able to compete. Volvo (now owned by Geely, one of the bigger Chinese car companies) might survive the transition to electric. Hyundai might make it too- this year's Kona EV is a compelling car with lots of consumer demand, but they're not making nearly enough to meet that demand. (Hyundai at least announced this week that they are shutting down their internal combustion engine design division and applying those resources to electric drive trains.) We'll see.
Yes, there will be lots of electronic tech in all of these, and there will be those with good support (like Tesla & BYD) or those with promises of free over the updates with no follow-through (like VW, until recently- they will have to turn that around, and seem to be trying), but the competitive market will kill off the laggards fairly quickly. The internal combustion engine is already dead for cars & light trucks 2030 will be way too late for legacy automotive companies to have fully made the transition. The plunging year on year cost of batteries (along with battery performance improvements) has already hit new-car cost parity (for a better, lower maintenance car), and going forward only the most ardent "vroom vroom" noise enthusiasts are likely to be buying new internal combustion cars (at any price point) after 2025. That seems shockingly quickly, but Chinese and Norwegian markets have shown doubling or tripling of market share in EVs, even when they were more expensive than internal combustion engine equivalents, and now that the costs/prices/margins have all improved on the EVs they can be sold at even more competitive prices. (Tesla has about a 30% gross margin, about 3x the margin of GM or Ford on their internal combustion cars. They're only that expensive because of the limited competition, and year+ backlog of orders on the Model 3 & Model Y.)
