Here is the title of the original paper that I read in 'Electronics Letters'
Unfortunately, I don't have a copy at this time, and the IEEE is giving me trouble at getting it from them, even though I am a Life Member, and have been with them since 1965.

Mercedes already did that in the Maybach. All they could get from the cells was enough juice to run some cooling fans however. There was a weird car for the ultra low power competition years ago covered with cells but not something you could drive to work.

The RV with solar panels probably would not work that well either. Not enough solar generation to get far.

Solar panels are already pretty high efficiency so don't expect a breakthrough. If they are at 26% now (Best performance Solar cell efficiency tables (version 50) - Green - 2017 - Progress in Photovoltaics: Research and Applications - Wiley Online Library) and that's 10% of the power needed you can't get where you want to be.

I did some work with Bentley and saw a lot on the inside that was not too impressive. The Bentley, Audi A8, and VW Phaeton share the same chassis and drive train. I heard that the VW was the best built of the lot. The Naim audio w. BMR speakers was not serious as we would think a premium audio system should be. The tuning was all done in Germany. The Naim amp cost $1M to certify (The car biz is not easy to make money in) and not made by Naim. Only Tier 1 vendors need apply. At one point the Naim guys said they were lending credibility to Bentley!.

Indeed. The W12 engine originated a long time ago and first saw commercial duty in the Phaeton and A8L I believe. It's origins are 2 of the VW Golf R32's VR6 engines mated together iirc. The best car in that class in the VAG group is the Porsche Panamera. It is a bit ugly though.

Those VWs have a quality I find hard to articulate, but the best would be 'as if the whole car is in your hands when you grab the wheel'. You not so much turn the steering wheel as well as swinging the car around. If you know what I mean.

This was a V10 Phaeton a friend was test-driving and he let me hold it for some time.

Describing cars is a thankless job indeed.For example, the more south of Europe you go, tastes change in comparison with Northern Europe by design. An Alfa Romeo will never work as smoothly and reliably as a German or Swedish made cars, but it will give a sense of life, soul, fire and brimstone. It is not said in vain that most people who get to druve Alfas will inevitably end up owning noe or more of them. Alfas have a special way they do things, not necessarily bettter than the say German way, but certainly different.

To assess a car, you have to keep a broadd mind. For example, my own 2012 Chevrolet Cruz, despite the GM and Chevrolet logo, is an excellent example of a mid sized German car, since it was designed and manufactured (engine drive train and mechanics in general) by Opel of Germany (even if it was assembled in South Korea in ex-Daewoo facilities), with typically Opel characteristics, but tempered by Big Daddy GM, so it has better road golding than most Opels, is not sickeiningly soft as most Opels, it has by far the best 5 speed manual gearbox in terms of ease of use but with some miscalculations (in my view) I have ever come across (inc. Mercedes-Benz), a brake system designed by some geek at home on a race track (outstanding) and the best electrical system I have ever seen on any car at any price (the part where Americans usually shine). But it can't take the rough handling and cornering an Alfa usually does with ease, and, while smooth in operation, it has no "heart and soul" a typical Alfa possesses.
 
In my years of technical work, the one thing that stands out is that I always managed to witness the breakthrough prior to anyone else, usually because I was the only one present. Those are some great moments for sure. Something my more educated coworkers had to see the "next time".

I liked the headlights on the A8, were some powerful leds, but they wouldn't sell them as a spare part unless you could prove ownership.

I had a ton of fun playing around with car suspension back 25 years ago, ultimately changing roll centers along with everything else, even adding a bit of caster to the rear, something Porsche did a few years later. Was just reading recently about a newer Lotus that won the national autocross, was showing how the raised roll center in front gave him a great advantage, yep, works pretty good that way...
 
Did anyone notice that we lost bonzai? His account is disabled 'at his own request'.
A shame. Another capable designer driven off by the semi-guru-bs-ing and the snake oil peddlers.

Well he did say
I would have hoped that there was a bit more concern for those on the end of Mr. W's incessant stream of vitriol, insults, denegration and downright obtuseness.
As I was beginning to suspect, some are golden.
I am outta here. Permanently.
Good day to you

So somewhat to the point. Still a shame when people go and we've lost a few over the last 12 months.
