Compressing hydrogen for storage in a practical volume takes about a third of the energy content of the hydrogen itself, and there's no practical way to get that back when expanding it. Storing the hydrogen in some sort of chemical compound doesn't make the hydrogen just magically attach itself to said compound and then release itself at will, either. Storage and transport is a nightmare. It chemically attacks some metals ("hydrogen embrittlement"), it leaks through some materials, it leaks out through the tiniest gaps.

I was involved in a prototype hydrogen fuel cell project for a large retailer who were going to be using it to operate their forklifts in their warehouse. It was expensive. As far as I know, it went nowhere beyond that initial prototype, and <checks files> that was in 2012. <checks google maps satellite view for similar system at another facility - it's plainly visible if it were there! - Nope.>

Did anyone see this: https://www.carscoops.com/2020/06/20...-updated-tech/

So it appears that the 2021 Q5 45 TSFI will be a 12v MHEV, and the 2021 Q5 55 - Will be a full PHEV. ( They also somehow made the SQ5, .4s faster to 60 so 4.7s ), and that in Europe it will only be offered as a Twin-SCR Dosed 2.0 TDI. ( 201 HP / 295 ft/lbs ).

Overall this is GREAT news for the general Market, that means each and every option of Q5 this year will have statistically and potentially significantly reduced emissions.

I was very interested to see that the 45 TSFI is a 12V mild hybrid because there was no info on that actually happening. Good things to come it appears. We need all improvements we can get.

Regarding the use of the word "being progressive' and so forth and to bring it more on topic of the automotive world, I would argue that driving an energy efficient vehicle being a TDI, an EV or hybrid is definitively "progressive".

What else would it mean then?

The 2020 Q5 55 PHEV had a 5.0s 0-60, of course they hadda find some way to shave off .4s otherwise the S Model was Slower than the non S model and that didnt seem right.

From the article it looks like again they wont give us black optics on the PHEV, bummer.. oh well, nothing some vinyl wrap cant take care of.

Thanks for the link, im in the market for one of these fine machines.

Audi having increased complexity with its dubious reliability record gives pause (although there are design areas where mild hybrid systems are simple enough). Saying that reduced emissions will be "potentially significant" loses the fact that new cars are already emitting very little through the exhaust (while concentrating on industrial and construction emissions is the way to go). Audi interiors are ruined by the tacked on iPad look while touch pads should be eliminated as an unnecessary and unsafe distraction.

To paraphrase a quote from a movie, if you build it, they will come. As the charging networks grow, I'm sure EV adoption will be right behind it. The pandemic didn't exactly help any growth, but that too will pass.

Nayr - You're 100% right. I was just questioning the enhancement since the power and torque figures are identical to the outgoing model. So I am quite curious where they picked up .4s 0 - 60. Probably a combination of things, but interesting none the less.

Tin Man - While I agree with you that new cars are more efficient vs older cars. That's not always the case and SUV's and trucks in particular need some help there compared to passenger cars. Also when you consider the amount of people using them is always going up. Any small reduction in emissions goes a crazy long way. I agree on the ipad and etc.. look, unfortunately that is a design trend that was started by Tesla I believe, and ALL manufacturers are following suit.

El Dobro - Field of Dreams is the movie you're thinking of. Most modern adaptation is Kevin Costner. I also agree that EV adoption, regardless of vehicle make, lives and dies by its charging network.

Interestingly, Mazda is going the customized ICE route for better emissions and fuel economy while eliminating large touch screens on at least its model 3. They are also electrifying slowly.

The 2020 Q5e loaner I had for a month was the first Loaner I had in my life that got better Fuel Economy than the Diesel I took in.. and the kicker? it was fast as ****, quicker than the SQ5..

Audi's dubious reliability record? Touchpad is too distracting? Some grade A BS right here folks.. Guy drives a BMW and a Jag and says Audi is dubious reliability wise? lol

MMI is 100% usable without the touchpad, it only exists to make data entry quicker instead of flipping through the alphabet one letter at a time you can write out the address.. Neither of which you do while driving unless you got a co-pilot operating it.. I suppose you'd rather have a giant touch screen display full of finger print smudges and playing russian roulette trying to press a button on a rough road.

Both cars are stone-cold reliable diesels. Enjoy your Audi/VW and hope it lasts anywhere near where mine do....

https://www.bmwblog.com/2016/02/01/w...mercedes-benz/
"Under six years, all of the cars are relatively similar, in terms of cost and reliability. This is because the cars are pretty new and typically have less than 100,000 miles on them, so not much is going to go wrong, at least not many important things. However, Audi is still the brand with the most problems and costs the most to fix. BMW sits in the middle with Mercedes being the most reliable, therefor the cheapest. After six years, things start to change. As the cars rack up more miles and, possibly, more owners, they do tend to break. Audi is still the least reliable and most expensive of the three brands, with BMW still in the middle and Mercedes leading the pack. However, after twelve years, things tend to even out again, as the cars are quite old and people tend to live with minor problems without having them fixed."

BMW is well known for excellent diesels while making really iffy gasoline V8's consistently. My German mechanic believes BMW doesn't really know how to build a proper V8 while generally Mercedes does....

My uncle bought a PHEV Pacifica minivan yesterday. He's quite pleased with it. He's also owned a number of cool vehicles- several air-cooled busses, a '67 Porsche 912, a Corvair, a 80's Toyota van, a Boxster, a red line Saturn sky, among many. I'm excited to see the Pacifica, he's driving it out to the farm this afternoon.

Nayr,

That's good that you seemed to like it. I will say that is fairly interesting to me going forward if Audi never releases another stateside TDI which I believe will be the case. Because like you I think of the efficiency of it. That vehicle ticked MOST of the boxes for me. The only thing I didn't like myself was that the Q5 55e is 200lbs heavier than my Q5 TDI. 4650 vs 4450 lbs. But having said that if you optioned the Q55e w/out the pano, it has been shown to increase the weight by 200lbs by itself. So that could do it for me. Also it would shave a little time off the 0-60 ... hahaha... getting you just below 5s. Would probably make a decent efficiency gain in EV only mode.... but I digress...

It's official, Tesla is now the world's most valuable automaker! Quite a meteoric rise in the mere decade since they went public. One thing is for sure- it hasn't been boring.
