Aren't most diesel-electrics of the series hybrid type? I believe the main point of them is that diesels can be made hilariously efficient when you optimize them to run at a single RPM for loads like running a generator, which then powers the drive motors. Gas engines are mostly used in parallel and series-parallel hybrids for the aforementioned reason.

Uthor posted:A big problem is the people most served by the limited range live in apartments in cities least suited for running electrical cords to their cars (especially if Street parking is involved). Let's say, for example, you live in Alpharetta, GA and work in Atlanta (which more than 50% of people in Alpharetta do). You have a nice house in the suburbs, and to pay for it, a 26 mile commute that mostly involves sitting on state highway 400. You wake up in the morning, drive your car into the city, park it at your office, drive it home at night. That's 52 miles / day, or over 13,000 miles / year. If you did that in an EV, you'd pull it into your two car garage at night, plug it in, and let it recharge. If your EV only has a 200 mile range, you still have tons of leeway to pick up kids from daycare, run by the grocery store, whatever you want to do. That's 13,000 miles / year of emissions you're not emitting, and 13,000 miles / year of gas you're not buying. There are suburbs and exurbs like this all around major cities. The world isn't divided up into city dwellers and farmers. EVs, with their <200 mile ranges, could easily serve as everyday vehicles for huge swaths of the population.

Diesels are awesome on the highway but suck sitting in traffic. Electric works awesome sitting in traffic but sucks rear end at highway speeds. See what I'm getting at here? Even with my 19 mile 50/50 commute, I still average around 40-41mpg per tank. And that includes me romping around on it. On days where there's very little traffic, I can push upwards of 50 mpg, and this is with a TDI that has 240torks and 140hp with a DPF.

veedubfreak posted:Why is there still no one offering a diesel/electric hybrid in the US yet? Cost? Ignore all the "ignorance" and "stigma" bullshit that answered you. In short, diesel fuel != diesel fuel. "Diesel" is a thermodynamic cycle, not an industry standard for fuel. Engines designed to run on EU diesel fuel (well, any engine more delicate than a tractor/truck) will choke on US/Aus/Asian diesel fuel as ours isn't refined to the same degree, and as an added insult won't pass emissions requirements (because of all the extra crap in our fuel that these engines can't process and just poo poo out the back). And the cost of upgrading our refineries isn't deemed worth it to satisfy what would be a fairly small market in the near-medium term.

All on-road diesel sold in the US is ULSD (Ultra Low Sulfur Diesel) and has 15ppm. European Diesel is 50 and 10ppm. A Euro Diesel can run on NA Diesel no problem, and won't choke on the sulfur at all.

Captain Postal posted:Ignore all the "ignorance" and "stigma" bullshit that answered you. I attended a presentation by a Ford powertrain engineer a few weeks ago, and I asked him about diesel cars in the US. He claimed it was a combination of different emissions standards between EU and US, and the cost. According to him, Chevy has sold around 300,000 of the new Cruze with only about 3,000 being diesel. He also said that although the diesel on the F series is around a 9k option, about 3/4 of the trucks sold get it. His idea was that the added cost of a diesel makes more sense to consumers on more expensive cars, such as Mercedes and Volkswagen.

A Melted Tarp posted:Does that matter with a CVT? To expand on this, no it makes no difference. The thing is, hybrids don't have a CVT like you're used to. In the simplest form (like a prius) they have two motor-generators and the ICE hooked to the three parts of a planetary gear set. Changing the rotation speeds of the three in relation to eachother gives you any direction, speed and ICE:electric ratio you could ever want. There is no reason whatsoever a diesel hybrid wouldn't work; indeed, it would be more fuel efficient. It is purely market-related poo poo that stops them being more common in passenger cars. A bit late, but on the hybrid/electric styling front: toyota released the prius and because it was mutant looking it was instantly recognisable and gave people bullshit greenie-cred. They hundreds of thousands of the things. Honda simultaneously released the civic hybrid, which outperformed the 20 series prius in every measurable way, but looked like an ordinary civic with funny looking wheels. They sold negative twenty. Diesels in passenger cars: one of the best cars I get to drive on a routine basis is the Kia Rio with a 1.4L diesel, 6 speed manual and idle stop-go. Compared to every other (non-performancy) small car I've ever driven it feels like it has great, smooth power and infinity torques whilst being insanely fuel-efficient. With the ESC switched off it will happily light up the wheels in second gear, no clutch required. Diesels are great and I will defend them to the death.

Diesels are expensive, even more so with US emissions equipment, and hybrids are expensive. Since the actual economic case is kind of marginal for most hybrids and pretty much non-existant for diesels, putting the two together is just going to make a really expensive car that may get pretty good fuel economy but will never actually make back the additional purchase price. Think of it this way, you can get more power with turbochargers, or with a big engine with lots of cylinders. So the ideal engine would be a big turbocharged V12. Except the number of people who are willing to pay for a big turbo V12 is pretty small. The number of people who are willing to pay a lot of money for a diesel hybrid very good fuel economy is even smaller.

A Euro Diesel can run on NA Diesel no problem, and won't choke on the sulfur at all. The sulphur content is close, but there's still the cetane ratings: Wikipedia posted:The current standard for diesel sold in European Union, Iceland, Norway and Switzerland is set in EN 590, with a minimum cetane index of 46 and a minimum cetane number of 51. Premium diesel fuel can have a cetane number as high as 60. Someone smarter than me can tell us if that's actually an important difference.

Edmund Honda posted:The sulphur content is close, but there's still the cetane ratings: My understanding, at least on the TDI and its somewhat troubled Bosh high pressure fuel pump front, is that the lubricity of US diesel fuel is nowhere near what the spec theoretically calls for, which was already less that what is expected in Europe. It's not documented particularly well since it's only really started to matter relatively recently and there's no real way of enforcing anything from either a regulatory or consumer standpoint. It's also not uncommon for diesel storage tanks to end up with some amount of gasoline contamination, which makes a bad situation substantially worse since gasoline doesn't lubricate worth anything. It's kind of a lovely situation for both OEMs and consumers, since it's really hard to prove definitively why something like a HPFP failed after the fact. The cherry on the poo poo cake for TDIs is that when the HPFP grenades it usually contaminates the entire rest of the fuel system with shrapnel and other bits, which generally requires complete replacement of the entire fuel system. Cetane also matters, but more for ease of starting/power/economy than for longevity, particularly of fuel system components.
