Here’s Why You Shouldn’t Be Using 85 Octane Fuel

Here’s Why You Shouldn’t Be Using 85 Octane Fuel

In high-altitude areas, 85 octane fuel is offered because it’s less likely to cause engine knock since the air is far less dense — but this specific octane is still advised against in the owner’s manuals of newer vehicles (as in, basically, cars made within the last 30 years).

That’s because of the construction between older and newer vehicles. Older engines had mechanical control of fuel injection and ignition timing — and that depended heavily on your manifold pressure. In higher altitudes, you’re not going to get the pressure you need because the ambient pressure is low.

Newer engines, though, have electronic fuel injection and ignition timing — which enables those newer engines to compensate for any low ambient air pressure. You’ll still lose power, but the engine is able to compensate for any losses. So, the problem won’t be quite as obvious as it would be with a car from, say, 1962.

Putting 85 octane in your car probably won’t kill your engine, but it does have the possibility to cause problems — and to void your warranty in some cases.

Tech Icon Steve Wozniak May Be Starting A New SpaceX Rival

The tweet also embedded this video:

The video is one of those vague, arty-ish PR things designed to just convey some sort of general tone and feeling, and it does just that. And while no specific goals were made clear beyond some general nods to exploration, unity, accessibility, climate issues, and humanity’s past space achievements, there are some interesting images in there worth a bit more scrutiny.

Like this one:

That’s a Mercury capsule, the first crewed spacecraft Americans used in the early 1960s. This image seems to show a Mercury docked to some sort of orbiting…equipment, something that never actually happened in any Mercury mission.

This one seems to be a little bit of a troll to our particular audience:

Yeah, it’s some dude shifting what looks like an automatic transmission as if it was a manual. I mean, he could be shifting from N to D or D to 2 or something, but still.

This next one may be more of a hint as to Privateer’s plans:

This shot above looks like the interior of a Soviet/Russian Soyuz capsule during re-entry. I don’t think it’s actual footage, but a recreation.

Speaking of not actual, this does not appear to be the actual ISS:

It looks like the International Space Station, but note that large habitation ring and the different pressurized module shapes. Maybe it’s a future variant of the station?

I don’t think I really learned all that much from the video, other than they made decisions to show space events and hardware that aren’t ones that actually existed, for some reason.

There’s been some discussion that the company is going to be in the orbital-junk cleanup business, possibly with spacecraft made from 3D-printed titanium, as a company called Desktop Metal reported that Privateer is one of their first customers to use the tech.

It appears the company will keep quiet until the Advanced Maui Optical and Space Surveillance Technologies (AMOS) Conference, starting tomorrow.

I’m very curious to see what this is about, because Steve Wozniak isn’t really the same kind of person as the tech billionaires who have started space companies so far.

Wozniak has always been more about making technology accessible and useful to everyone, donating time and equipment to school districts, and he’s fundamentally a great engineer with a true love for machines.

Did you know how the dude managed to get high-resolution color on the Apple II by exploiting a quirk of how televisions produce color? He managed to get six colors on a 280×192 pixel screen with a handful of chips, while it took IBM’s CGA graphics card well over 100 chips just to get four colors on a 320×200 screen!

If whatever that is can be translated to doing something in space, well, then I’m excited.

Here Are Your Nightmare Two-Car Garages

2009 BMW 7 Series

Some cars are just plain, old not good cars. Whether they are unreliable, have terrible driving dynamics, baffling design or, worse, all three, some models really can be nightmare fuel.

The worst of the worst for me would be out-of-warranty German luxury cars. Specifically an F01 BMW 750i with the terrible N63 twin-turbo V8 and a VW Touareg V10 (Sorry Mercedes).

The F01 7 Series was just not good. If you want one you can try and save yourself some trouble by going with the I6 powered 740i, but then you still have to deal with the electronics. The 750i is worse. Not only do you have the unreliability of the engine (the hot vee setup with the turbos in the valley of the engine was not a good idea on this thing) but you have to deal with the electronic issues as well. The Touareg V10 and its problems are well documented.

We asked readers what was their nightmare two car garage. These were their answers.

Apple Car Contract Will Probably Go To LG And Magna: Report

Wow, it’s been a hot minute since there was new Apple Car news, huh? Ever since the will-they/won’t-they saga between the tech giant and Hyundai fizzled into the troposphere, things have been astonishingly quiet. Too quiet. Apple needed another willing partner, or partners, to get things moving again. It appears it’s found them in Magna and LG.

Magna and LG’s joint electric powertrain business is reportedly close to inking an agreement with Apple to collaborate on the company’s long-rumored semi-autonomous EV, according to the Korea Times:

“LG Magna e-Powertrain is very near to signing contracts with Apple under which they could handle the initial volume production of Apple EVs. Contract details are still being discussed,” a source familiar with the issue told The Korea Times, Tuesday.

The production volume the joint venture could handle won’t be that huge as Apple is mostly intending to use its first-generation EVs as an opportunity to evaluate their marketability, according to the source. “Because LG Group affiliates including LG Display, LG Chem, LG Energy Solution and LG Innotek are already included in Apple’s parts supply chain, Apple doesn’t have to worry about any supply chain issues. These LG affiliate are qualified to guarantee production yields and faster delivery of parts needed for Apple EVs.”

There are a couple of reasons why this potential deal seems more likely to work out than Apple’s previous flirtation with Hyundai. Magna is a contract manufacturer by trade, of course, and LG is one of Apple’s existing suppliers. LG produces monitors sold via Apple’s retail channels and recently got out of the smartphone game, too. While they’re both tech companies, they’re not necessarily opposing each other in many product categories these days.

What’s more, as suppliers and manufacturers, neither LG nor Magna will likely take issue with Apple claiming all the credit for this car in the way that Hyundai was reportedly very uncomfortable doing.

All in all, it just makes more sense than the Apple-Hyundai partnership, which seemed doomed from the start. The Korean automaker telegraphed its insecurity and ambivalence about the whole proposal every chance it got, and all of us watching were like guests at an ill-advised engagement party that everyone knew was destined to end in tears.

The timing couldn’t be better for LG in particular, which minted its LG Magna e-Powertrain collaboration in December and hacked off its mobile division earlier this month. The joint venture aims to marry “Magna’s strength in electric powertrain systems and world-class automotive manufacturing with LG’s expertise in component development for e-motors and inverters” according to the companies’ shared press release. An Apple EV project would certainly mark quite the new revenue stream to kick things off.

And Apple itself is no longer shying away from admitting that it’s really, really interested in cars. In an interview on the New York Times’ Sway podcast published April 5, Apple CEO Tim Cook compared autonomous cars to robots, adding “we’ll see what Apple does.” NYT’s Kara Swisher pressed Cook on whether that’d take the shape of a full car or merely software, to which Cook responded:

We love to integrate hardware, software and services, and find the intersection points of those because we think that’s where the magic occurs. And so that’s what we love to do. And we love to own the primary technology that’s around that.

Seems like Cook might’ve finally found some friends willing to help Apple do exactly that.

I’m Not Sure If I Think Volkswagen is Really Changing Its Name To Voltswagen, But Let’s Talk About The Original

As I suspect you’ve heard, Volkswagen of America is claiming that they’ll be changing their name to Voltswagen of America, as a way to highlight their new focus on electric vehicles. You may also have heard that we at Jalopnik are pretty skeptical this is really happening, to the point that our bossman Rory said he’ll get a VW tattoo if they do it. It’s April Fool’s day the day after tomorrow, people. More significantly, though, is that “Voltswagen” for an electron-powered VW is by no means a new name. In fact, it goes back to at least 1968.

Sure, VW is playing it up, with the Voltswagen name used on their website showcasing the ID.4, and they did tweet this:

Okay, okay, we get it. Maybe VW will use the Voltswagen name in specific EV branding, but I’m not sold they’re changing the name of the whole company in the U.S. to “Voltswagen of America.”

We’ll see how it plays out on April first. Until then, I’d like to talk about where I think the Voltswagen name first came from, and I’m happy to say it’s a pretty fun story.

It’s from the Great Electric Car Race of 1968.

That first Voltswagen (well, until we find out about an earlier one) was a 1958 VW Type 2 bus, owned by Caltech student Wally Rippel, who converted it to electric power around 1966 or so, and drove it around town to, as Caltech’s magazine Engineering and Science reported back in 1968,

“…to demonstrate an alternative to smog.”

Rippel then became part of an electric car team at Caltech that challenged an MIT team to a cross-country electric car race: the Caltech team would drive from Pasadena, California to Cambridge, Massachusetts, and the MIT team, in a 1968 Chevy Corvair donated by GM and converted to electric power at MIT, would travel in the opposite direction.

As you might have guessed, attempting this sort of cross-country EV race back in 1968 was borderline bonkers. It wouldn’t even be easy to do today; back then, it was almost Sisyphean.

To accomplish the feat, 54 charging stations were established along the 3,311 mile route, placed between 21 and 95 miles apart. Some of these charging stations were extremely improvised, like this one in Winslow, Arizona that looks to be tapping right off a small roadside power transformer:

The race was, by all accounts, something of a shitshow: long charge times for both cars (45 minutes to an hour), the MIT Corvair caught on fire, one of the Caltech drivers got the mumps, both teams ended up burning out critical components (motors, transformers, etc), and both teams made significant use of ice to cool the batteries.

The Caltech team only used 50 pounds of ice, and only when recharging their lead-cobalt (a variant of lead-acid) batteries. The MIT team’s more advanced nickel-cadmium batteries constantly struggled with overheating, and had to be packed full of ice pretty much all the time, with the team using 350 pounds of ice during the trip.

The race was a great underdog vs. rich kid sort of story, like most movies made in the 1980s. Where Caltech’s Voltswagen was just a student’s personal project car, built using pretty basic and mainstream electrical tech, MIT’s donated brand-new Corvair was cutting-edge in every respect at the time, and as a result was faster (it could do about 60 MPH instead of 55) and was supposed to have a longer range, and recharge faster, as well. It even had a special aerodynamically optimized front facia. It did look pretty cool.

The advanced NiCad batteries used by the MIT team were worth $20,000 in 1968 dollars—that’s about $151,000 today! MIT was not playing around, here.

In practice, though, the technical advantages really didn’t come to matter at all. The MIT car was plagued by technical snags and, while it technically finished the race before the Caltech bus, penalties assessed for all the time it had to be towed en route (the Corvair had to be towed 250 of the race’s first 500 miles at a penalty of 5 min per mile!) eventually gave the win to Caltech, with a time of 210 hours—30 minutes less than MIT.

They won by just 30 minutes! That’s amazing!

The Voltswagen wasn’t all that primitive, though—it did have the ability to do some regenerative braking, using the motor driven by the wheels to generate electricity to recharge the batteries, which was used on a long downhill grade into Needles, California.

Caltech’s Voltswagen proved a few crucial things: sometimes proven reliability beats bleeding-edge tech, and if you’re doing a cross-country drive, it’s great to have a vehicle you can easily sleep in.

You really should read through the whole Caltech article; it’s a fascinating look at how far we’ve come and a great insight into how clever and bold these early EV pioneers were.

Wally Rippel, the owner of the Voltswagen, later went on to work for JPL and then later Tesla, helping to develop the motor for the original Tesla Roadster around 2006.

Maybe Volkswagen will really become Voltswagen. Maybe not. Either way, it’s worth taking a moment to commemorate that original 1958 Voltswagen, the winner of the first ever Great Transcontinental Electric Car race.
