Audi A8 TDI: Range For Days... Literally 

Because diesel is overpriced here.

I love suvs tho

***** With the exception of six-cylinder BMW 1-series, you're not missing anything in terms of our hatchbacks. Most of the estates are pretty dull too - except those based on the interesting British and German saloons that you get anyway. You also REALLY don't want diesel...

Wurzelzwerg1212 Americans don't hate diesels .

In Europe diesel fuel is just a little bit cheaper than gasoline and around 40% of cars are powered by diesel. I drive 2003 Audi A6 1.9TDI. On one tank of fuel (18.5 gallons) my range is around 920-930 miles driving 60mph on a cruise control which means 50-51MPG on the highway. Normal freeway driving with speed of 70-80mph means 740 miles of range (40MPG).

A much bigger tank, bigger vehicle, just not even remotely comparable. Let's hear your MPG, your engine displacement and power, your gear and final drive ratios and your drag coefficient so we can work out the actual engine efficiency.

Does it have heated AND cooled seats tho? Does it have a radar cruise control? Does it have google maps with street view? Nahhhhhhhhhh

It's a 2014 freightliner cascadia evolution. It has a Detroit Diesel DD15 560hp@1800 rpm and 1850ft-lbs@1100rpm. Has a variable turbo with turbo compounding energy recovery system. Has a 15 speed overdrive gearbox with a .76 overdrive and 3.42 rear gears. The engine is still in break in but I am getting 10.76 mpg life average as of now. Freightliner doesn't give the drag Coe of the tractor.

Yes it has leather heated and cooled seats. Has radar predictive cruise control but no google maps. But does have navTEQ navigation built in.

brian hilligoss That is a rocket you have :) Must be great fun to drive.

Actually, the facts are that A) Hybrids have slightly higher production emissions but B) Hybrids have lower lifetime emissions than their non-hybrid equivalents, as in, hybrid diesels are more efficient and pollute less than plain diesels as well. The accord hybrid has a 1.3kwh battery, lithium ion's energy density is 200wh/kg, which means the accord hybrid will have 7kg/16lb of lithium in its battery pack. What're the emissions that go into manufacturing 16lb of lithium in a battery pack weighing less than 100lb? Certainly less than the 9mpg difference over a car's lifetime.

Well, then compare apples to apples. You want a FOUR cylinder MID SIZE sedan comparo, go look at the Passat TDIs that were sold through 2015. I have numerous customers and friends and a family member who owned them and on long highway trips the cars legitimately get 50 MPG. Combine that with a 17 gallon fuel tank and what do you get? You get a car that walks all over your Accord Hybrid for range, and it's a bigger car, arguably more comfortable and has quite a lot of torque, effortless passing on the highway that doesn't require downshifting (because the diesel makes prodigious amounts of low and mid range torque), keeping the cabin noise to a minimum. The A8L is basically a limo. The rear seats have more leg room and just as many features as the front seats. It also has a V6 instead of a 4 cylinder and makes 100 horsepower more than the 4 cylinder diesel and 400 ft-lbs of torque... and it still gets 37 MPG highway.

well, it's just marketing. it's how audi calls the eco versions. anyway, i do not see the point of this show. that is neither madness or unexpected. this cars are build to drive throw germany at high speeds on one tank of fuel. does not matter if audi, bmw or mercedes. when i had my e91 320d, i once drove it from berlin to monaco (about 800 miles) on tank of fuel. that way more demanding then this trip.

amduser86 My friend has a BMW 730d and on one thank he usually drives around 840 miles or 1300 km. He refuels when it starts on reserve so there is probably a bit more to drive.

amduser86 Yeah, clean diesel is a oxymoron little bit. I have very similar experience with 320d xdrive E92 - I stoped to refuel after 1200km/750miles on the way from Prague to Dubrovnik, just because I had to pee. You can go forever with modern diesel and not small tank. But thats like the only one pro of diesels. My next car is going to be a petrol, for sure.

Clean diesel refers to Audi diesels which have a Urea/AdBlue tank which is used to scrub the exhaust emissions(much like in a truck). This is in contrast to alot of European diesel cars which feature a DPF system.

Gosh, reading this is 2024... 😢

@@RomanTrollanski Welcome to 2024 lol

I got my drivers license back in July of 2014 😭 can’t believe it’s been 10 years worth of driving.

+a8s320 Why they don't use metric?

ken6x Forza 5 dude it's not some damn toy...

CTT would have made it to the end of point A, but die back towards point B.

ken6x Hahahahahaha legend!!

It's not like you drive from new york to california either.

Hehe i get from the West coast to the East coast on about 1/8th of a tank. And 2 hours. Hurrah for Scotland :D.

Range is how far you can go on a tank. Not how efficiently you do it.

You're right, I put my point across poorly. When you are trying to make something look like it has range it made more sense to showcase how many miles to the gallon it can do as that is the ultimate test. If you had an A3 with the same size fuel tank as the A8, it would have a far greater range.

Tony McSpadden Yes, but it would be an A3. I just drove the new A3 up in San Francisco. And let me tell you, there's no way in hell I'd want to do an 867 mile trip in that car.

TheSmokingTire I drove an X5 with the 305 section rear tires 3.0 diesel from Luxembourg (Asselborn) to France (Narbonne) around 980km - 610 miles , fully loaded with a bike rack on the rear , averaged around 55mph , it has a slightly bigger fuel tank than the Audi , but for an SUV on fat tires , I thought it was incredible . A euro 2001 320d on the other hand does 730 miles with 16.8 gallons . Dont get me wrong a diesel Audi is great , but I find that the older diesels are much more fuel efficient and reliable. New diesels do multiple injections every compression stroke purely for emissions, and that kills the fuel economy. Clarkson even drove the old big 4.0TDI 800miles

adpmol Yeah, and I went 67 miles farther than that.

Listen to their podcast.

Their podcast is legit good entertainment.

Neither has cheap gas prices 😅

U know it can change sound of exhaust?

Ranging from no sound to w10

everyone thinks they know everything? Except they don't. I put diesel in it, started it right back up and kept driving.

Okay, i'm not arguing my friend! Just as far as I've been aware, in the automotive industry running a diesel car out is a huge no no. But hey, things may have changed, especially with Audi's innovative TDI engines! It's most likely that they have a system whereby they reserve some diesel within the system so you don't have to go through this lengthily process if you do happen to run it dry :)

TheSmokingTire You seem to be lucky then, when diesels run out of gas you usually have to bleed the air out of the system to get it started again.

Brendan Cunningham Most diesels that's true - but I think Audi have put a self bleeding system in theirs. Hmm, after some Google research, apparently most modern common rail diesel injection systems are self bleeding.

+Brendan Cunningham correct term is Air-Locked

***** yup...lol

Blame what on the other guys? That statement makes no sense.

Tried to claim it was Thaddeus's idea. The biggest bottle of water and vinegar in all of LA was in the driver's seat the whole time.

MrNicholg That makes even less sense. Is calling a person a big bottle of water and vinegar an insult? you sound like the kind of person I'd quickly walk away from at a party.

range equals convenience. When you have a nice car, it's a nice convenience to not have to fill it up very often. It doesn't mean you NEED to drive 867 miles non stop in one tank, but in the real world it means that if you buy one, you will probably only have to fill it once, maybe twice a month driving normally. That's a nice convenience.

TheSmokingTire gues you made a point but i stil don´t see it great video tho keep it up id take 1 episode over 5 of big muscle

TheSmokingTire i totally agree with you and that why i drive A8 TDI 3.0 - fill the tank and you can forget about it for a very long time

MrTeetec Once you own a diesel. You'll find out why.

rotor13 SO TRUE

yeah but you have to keep in mind that the shitter is over 2 tons.... not nearly a passat... and with my vw polo, i drive 170 miles on 1/8 of the tank, which is 10 gallons.... but its also a three cylinder lol

automatic what?

TheSmokingTire automatic bang...

TheSmokingTire gearbox :P

niklasxl I was wondering the same. It is more fuel friendly with a manual gearbox and FWD.

niklasxl It's not 1985 anymore. Nearly every car that offers both an automatic and a manual in 2014 is more efficient with the auto. Not that it matters, since you can't buy an A8 with a manual anyway.

Apples and oranges. Also, they had 3 men in the car.

The car went back to Audi. So its up to Audi to fix if it has any issues. I've ran gasoline and diesel vehicles to the point of shutoff. None of them ever game me issues. Not because I wanted to.... but because I NEEDED to since it was my job to do this to cars.

i have seen one in ebay new for 74k that was flooded a little in the dealership and they changed the floor mats only ,and the car is great

Mine was TDI 2014.

MakerofAwesomeness Nice purchase. Hope you enjoy it.

Thanks man.

which would ruin the point of this video since it's about fuel economy, not about power

coenijn Who cares? Last time I checked fuel economy is not a big concern of this channel, nor is it of anyone who buys a german luxury flagship sedan. Besides, it would still be relatively efficient while providing awesome acceleration and effortless high-speed cruising.

The 4.2l TDI is available in the A8, at least here in Europe. Jeremy Clarkson used the old 4.0 version about a decade ago to do London-Edinburgh-London (starting and ending at the same fuel station on the North Circular). That's about 800 miles, whichever way you go.

ruskeee No, i agree, the channel is about beautiful and/or expensive cars and going fast. But this video is all about fuel economy, so why use a thirstier engine?

coenijn because it would result in a different probably more interesting video

I saw holes and spider webs, thought of the lack of TST health insurance, and said, "no thanks."

oh no! spider webs! yeah I don't blame you for not going in there....

Brown recluse, black widow, tarantulas, yeah no thanks.

36 MPG on a 4,500 lb car with AWD that can do 0-60 in six seconds. That's excellent.

TheSmokingTire true

Dylan Tindall and are we talking imperial 8-pint or weedy little US 7-pint gallons? Matt's using the latter, I think.

Old ones do. New ones shut down electronically before they get to that point.

then do it. It's so easy to write some shit like that on a youtube comment. Go do it, and make a video if it's so easy.

I don't think your foot can react as quickly or perfectly as radar-controlled cruise control, but we all agreed that if you got directly onto the highway and went 65, it would probably do 900-1,000 miles.

Zack Klapman Its not your reaction in terms of quickness; its driving style, say you set your cruse for 65 on a hill gravity works against the car and the transmission has to change to a lower gear to maintain speed bringing up the RPM's of the engine which will burn more fuel (not much but a little adds up over time). If you were to use your foot up that same hill but slow down to allow the transmission to stay in the higher gear the engine does not burn the fuel however you do loose speed which you would gain on the down slope all without using any more gas. All this is moot though since the point of the video was to imitate a nice relaxing trip with some friends and not a purely eco run.

TheSmokingTire my "shiet" was purley to state audi modern TDI engines potential ,not to dis u... so chill - u drinking too much coffe

Zack Klapman why would u want to mach or react like cruise controll - to what pourpose cc dose more bad thatn good - it durns more fuel and u not focused on the roud but on your sandwich

How many people do you think live in the USA lol?

Well, maybe. It's smaller and lighter and can be had with smaller/less powerful engines. But also have a smaller fuel tank. So it's hard to say if the A6 can do the same range or out-run the A8. Atleast better MPG.

How do you get "gas" mileage on a Model S ?

Kevin Walsh they use a formula to give a mathematical equivalent. Basically it converts kwH to e-MPG.

1) Tesla Model S has a range of 300 miles @ 55MPH. After that it needs to be re-charge, which can take several hours depending on how full you want the battery. This is far from ideal when road-tripping. 2) A plane ticket, or travelling by plane, defeats the idea of road tripping via automobile. The entire notion that road trips are boring as hell is subjective, I for one love road trips! I love driving, listening to my tunes, and letting my car rip in the open road. Based on my preferences, road tripping is something I genuinely enjoy. Before posting take a minute to think about what you're going to say because you're embarrassing yourself and your family.

Dan, it's not gas mileage so much as RANGE. How far can you go on a single charge in a Model S? 200 miles? 300? This Audi can go well over 800 miles without having to stop for fuel. I also know of a much older vehicle in VW's line up that can go even further (also TDI powered).

DrummerPGR Embarrassing my family? If you take the internet this seriously, you've got bigger issues to deal with than my opinion on road trips. Don't be so fucking dramatic. And I'll be the judge of whether or not I'm embarrassed - you can't decide that. (I'm not, by the way, because I know I'm right - but I digress.) I'm well aware of what the Tesla is capable of, as well as this A8. Nobody gives a rats ass about being able to drive 900 miles on one tank of $4/gal diesel anymore. This shit is old news that would have been relevant 15 years ago, but has been rendered pointless by cheap air travel, cheap econo-boxes, and just generally being cost-prohibitive. This car is a limousine, nothing more. If you're telling me that you are consistently driving your $100k diesel on 900 mile road trips so you can have fun and listen to music, you can jog on, because I don't believe you at all. People with that kind of money don't do that shit. Ask me how I know.
