Ford’s electric car engineers go crazy with 1,400hp Mustang Mach-E

Anyway, just like with Tesla, I expect that if you mess with the factory software to extract more features or performance you'd normally have to pay for, the manufacturer will void your warranty or lock you out of their charging networks.
The EV future doesn't look good for custom tuning.
Personally if I could retrofit my 240z with an electric drivetrain I would, I just wanna smoke some Tesla’s off the line :)
But then I perfectly know you are right about the general tendency of integrated and locked-in parts in engineering nowadays.
The Fast and furious style tuning is super easy on ICE cars but I expect it will be almost impossible in the EV future.
Given the utter simplicity of electric motors, I imagine that aftermarket creations will be much more common.
As a former EV automotive engineer, the complexity added to the newer designs to maximize efficiency has skyrocketed and so have the points of failure.
One EV project I worked at had the brushes fail after 20k KM needing the motor disassemble and brushes replaced. At another one we had attempted cooling the rotor and from too much vibrations, the coolant could leak inside the sealed motor totalling it.
People expecting EVs to outlast ICEs on reliability are in for a serious wake-up call.
I totally agree on the reliability point. ICE drivetrains have really been refined and typically last quite a long time. Last I checked, it's not usually the drivetrain that takes a car out of service anyway, so I don't expect EVs to really change the overall life expectancy.
My Tesla has been great, so far, but there are a lot of oddities that I don't think will age well. I probably won't keep it past the warranty period.
I think one of the reasons older Jeeps (with manual transmissions) are still really popular for off roading is that they are super mechanical and very easy to work on in the field. You can carry with you parts that are likely to break based on what you're doing and fix them yourself with a bit of know-how.
You can also tune them however you like as changing suspensions, axels, carbs, differentials, or even clutches is pretty straight forward if you have the tools. Hell, you don't even need to rely on the battery to start it as you can just push it to get it going. Super reliable in a sort of way if you're in the field and need to self repair.
They're just different - electric is better in a lot of ways and gasoline is better in a lot of ways. I don't think you'll see electric cars doing endurance racing anytime soon.
Their chief limitation is managing heat, and maintaining the DC motors themselves.
Torque is k*HP/rpm, whether electric or ICE. If you can slip the wheels you can go faster. It's well known in the supercar world that you can often do a great estimate of top speed based on HP alone, given how aero dominates at speeds above 100mph and these cars aren't wildly more drag-efficient than one-another.
Top speed ^3 * cross sectional area * drag coefficient = HP.
Which is why supercars are so low to the ground, having 1/2 the cross section effectively doubles your horsepower. Though that’s assuming the car can handle the forces involved.
That weight is terrible for all sorts of other reasons, but that massive ~4,900lb curb weight combined with all-wheel drive is a major factor in the Model S's 2.3 second 0-60 times.
The axle strength on this thing must be crazy.
7 electric motors must be able to crank out torque.
(people don't generally realize the model 3 performance is almost 500 hp)
I remember them being quite the experience though. The eye burning fumes in the air. The sound so violent that you feel like the thing could turn the entire track into a crater. When the things took off you could feel your organs shaking.
Not sure you can replicate that experience with an electric car. More likely tastes change and maybe drag racing dies out. Those races were the pinnacle of the ICE experience for me though.
It's been a long time since power was the problem in racing. It's all about keeping the wheels on the ground now. If you're burning rubber, you're not getting max acceleration.
I am not enjoying having a computer constantly between me and the road. I also don't like the new lower bound for car weight due to all of the modern safety regulations. Even if you have a modern car with a ton of power, you can never truly compensate for the physics equation imposed by all of that weight.
For example: A 1988 Honda Civic weighs somewhere in the realm of 2000-2200 lbs. A 2020 model year weighs somewhere between 2700-3000 lbs. This makes a huge difference in how a car feels to drive, especially at extremes that are more likely to be explored by enthusiasts.
Something like a BMW M3 E30 would be a dream hobby car for me. There is a reason the 80s-90s model years are starting to go up in value. Car enthusiasts want that sweet spot of purely analog controls, but also with working factory A/C.
Also, LiPo batteries can explode if you're not very careful with charge and discharge discipline. Even the small ones in cell phones can do significant damage that way.
Right now though we have some disappointing (from a power perspective) electric drivetrains from Prius' that can be swapped or a powerful but DRM'd Tesla drivetrain that is more work than it's worth.
People love to say this is due to regulation, but it really isn't. Safety regulations in the USA for automobiles are not terribly strict. It adds weight, for sure, but you can buy a 2100lb Mitsubishi Mirage with a stick shift. So mandatory safety aren't the biggest contributor to inflated curb weights.
Size inflation is predominantly driven by NVH and interior volume requirements from consumers. Dodge doesn't have to make the Challenger Hellcat a 4500lb two-door car. This car isn't fat for safety reasons, in fact, it score pretty damn low on safety tests.
Manufacture make heavy cars it because customers want gigantic, comfortable cruisers, with big engines, all-wheel job, 20" wheels on 265mm-wide tires, heavy duty lifted suspension, and full-length under-body trays.
Honda isn't immune to this, they don't even sell a car today that's as small in volume as your 88 Civic. The closest would be the discontinued CR-Z, which was a hyrbrid, or the no-long-sold-in-the-US Jazz/Fit, which is still quite a bit larger but only 2600lbs with a stickshift.
I love old Hondas, and you're right, they have a driving sensation that's impossible to get with modern cars. But don't blame regulations for Honda changing their ways, blame consumers. If people wanted a Civic with a 90hp engine, stick shift, four-wheel double-wishbone suspension, and 13" wheels, they'd sell one. Mitsu still does (for now).
People have said this exact thing for decades. It's because people old enough to remember being carted around in those cars as kids are finally getting old enough to be settled down and wealthy enough to have project cars. It has nothing to do with the vehicles themselves.
Within any given decade the things the rich kids got carted around in (or their dad commuted in) always command a premium.
A 1988 Honda Civic isn't purely mechanical. It still has an ECU, for example. It still relies on electrical sensors for basic operation.
> Car enthusiasts want that sweet spot of purely analog controls, but also with working factory A/C.
There's no shortage of new cars that still offer that, too, or recently used. You don't have to go back to the late-80s to get that. It seems to be mechanical steering combined with low curb weight that you're actually focusing on, which is still a market segment receiving new models. You've basically described every Porsche up until the 2012 model year, for example (when they first introduced electronic steering). Or the entire Lotus brand. Or specialty cars like the Alfa Romeo 4c, Toyota/Subaru FRS/GT86/BRZ, etc...
And, of course, you can't forget the king of sports cars - the Mazda Miata. 30 years later & it's still just as light as it's always been. And just as good.
> Something like a BMW M3 E30 would be a dream hobby car for me.
There's so much more to a car than spec sheets, and you should absolutely chase your dreams, but realize you can also basically buy a brand new M3 E30 today. The power, weight, size, etc... of the E30 is withing spitting distance of the GT86.
Both are front-engine rear-wheel drive. Both have manual transmissions (although a 6-speed in the GT86 vs. the 5-speed in the E30). Both have a ~2700lb curb weight. Both have a 101 in wheelbase. The 86 is a bit shorter length, bit shorter height, and a bit larger width, but all within a few inches. Both have a 4-cylinder engine at around 200hp, and both rev to about 7000 rpm. Both have responsive, playful suspensions, and direct steering feedback.
Regulations definitely didn't kill anything here as the same core specs still exist.
Lots of dedicated automotive hobbyists end up being specialized mechanical engineers. They might not know the formal math behind systems, but they have a reason to learn. Today's hobbyists might look up tables for calculating fueling requirements for the expected airflow of their setups, as tuning an engine invariably means figuring out airflow volume for an intake setup, then calculating injector duty cycles to deliver a set volume of fuel over a specific timespan.
I doubt there will be many people modifying new EVs due to their complexity. But people are definitely converting old cars to EVs and that requires a pretty deep knowledge of EE principals.
EVs are comparatively easy to get started on as a hobby. The production EVs are only making it easier by populating the secondhand parts market, and electric drivetrains are much simpler and easier to fit than ICE conversions.
Semis can have 2000+ mile ranges.
I am also excited to see battery densities increase, but so far the way we're getting comparable range in EVs is by allocating a greater proportion of weight to fuel. And recharging is still relatively slow.
nothing beats the distance over time you can get with a gas vehicle, given also how quickly you can add range.
Many years ago, we used to drive from the midwest to California every year, which was two 800 mile days. We covered that 800 miles in about 13 hours, which is an average of 60 miles per hour.
A few weeks ago, we drove 800 miles in our Tesla, and did it in 16.5 hours, which is a little less than 50 miles per hour.
Which is quite respectable actually.
I know not all EVs are Tesla, but it's interesting to see where charging is going (others will follow suit).
Supercharging v3 gives you 1,000 miles of range per hour of charge (approx. if you're in the 20-80% SOC range I think). If you take a 6 min bathroom (or other) break every 100 miles (roughly every couple of hours), you can replenish those 100 miles during that break.
Personally, I find superchargers "too quick", as I tend to stop for lunch with my family when I supercharge, and I find myself having to rush to finish lunch so I can get the car out of the charger for someone else to be able to use it. I wish there was an option to say "charge slower and give that juice to the other guy" (many/most current supercharger "pods" have to share the current flow with another car).
Pumping gas, I usually do not have time to even squeegee all the windows; I've never wanted to stop for lunch while getting gas.
600 mi at 10mi/hr is 10 hours, so probably ready for a break.
Also, it isn't a couple of hours at all. 10% to 90% charge in model 3 takes about 50 minutes using a V2 supercharger (the most ubiquitous one) and about 40 mins using a V3 supercharger.
And both take much faster to get to lower percentages, due to the charge rate curve looking more like a log(1/x) graph, with rapid charge rate at the beginning that slows down the more your car is charged.
I had the same kind of anxiety over charging too, but since getting an EV and doing multiple cross-state road trips in it and with just tons of daily usage, I found that worry to be unfounded.
If we did this in a Tesla, we would've had to stop far more times, or each stop would have to have been much longer. That's not great.

If only gas stations marketed their pumps like that. 10 gallons of gas can come out in 1.5 minutes in a Prius resulting in a fill rate of (500 miles range * 40 fill-ups per hour) = 20k mph! We won't consider the time it takes for the next user to get in and put the hose in because Tesla doesn't either.
I am a fan of EV vehicles as well but the long range fill up story is still not good.
Also it is not true that the supercharger v3 charges at full rate until 80% [1]. The curve drops off quite a bit shortly after 20%. The other points you made, well I never disagreed with that. There are a lot of benefits to an EV, but one clear downside (at the moment) is the long trip charging. This is just a fact and not an indictment about EVs in general

A large number of diesel cars can easily go over 600 miles. The Audi A8 and VW Jetta, to pick two random examples, can go 650+ miles on a single tank.
Basically, when not in emissions testing mode, the engine was running at higher temperatures which improves fuel efficiency but generates more NO from atmospheric Nitrogen. Also, the vehicles had insufficently sized or simply missing diesel exhaust fluid (mostly urea and blue coloring) resevoirs, so not enough was injected to react with the NO to hit targets; injecting DEF into the engine also reduces fuel efficiency. There was also something about not properly cycling the special catalytic converter for NO, which would probably show an efficiency difference on long trips.
I sold back my VW diesel and stopped paying attention, it would be interesting to see what the measured real life fuel efficiency is before and after the changes required by regulators.
Long haul trucks can do 2000 miles no problem, and extending the range is just a matter of adding more tanks. For now, there is no real competition over range in ICE cars, but if that becomes a thing, you can't win with batteries.
The only batteries that could compete would be lithium-air, and they are still in research phase, with no large scale commercial use in sight yet.
No matter how much battery you add, it's always possible to get more range with less weight in fuel, and with less diminishing returns.
In the specific case of trucks, in most places you can't demand a driver to do a 2000 mile leg on a single stretch and, with the required pause to rest, it's also easy to recharge. A limit of 700 miles should be considered a reasonable target for truck range on a single charge.
Airplanes are probably the place where internal combustion (or not quite internal, but still combustion, as turboprop and jets are not ICE's) will have a significant share for a long time. Even there, short haul small planes are already electrifying.
Many cars have 16-20 gallon tanks, so a 14 gallon is fairly small (although 600+ miles is plenty)
(Dodge Ram)
Pretty much pickup truck with the base 6cyl engine from the days when an 8ft bed also resulted in the vehicle being equipped with two gas tanks.
Also tons of random sedans beat 600mi.
BMW 730Ld will do 1000 miles. Even the petrol 740Li will manage over 700 miles.
When it was new (3 - 5 years old) my Dodge 2500 turbo diesel with a 120 liter fuel tank (31.7 US gallons) went 1,000km (620 miles) per tank. That's highway miles of course but 1,000km per tank is not exactly mind blowing it works out to 23.5 Imperial mpg or 18 US mpg.
An old cow-orker of mine said his old VW Rabbit diesel manual trans did 80 Imperial mpg (66 US mpg) on the highway. I have no way to verify that could be 10% BS. I've seen 50 US mpg stated (60 Imperial mpg). But who know synthetic oil, slim tires, highway miles, slow speeds all that may get it to the 70s mpg.
I have no doubt, musk will get the new roadster out there. But I have no reason to believe he isn't overpromising on the mileage.
We made a recent long trip with our Tesla Model S, which has about a 325 mile max range. There were plenty of superchargers, but it takes time.
You also end up stopping a lot more than once every 300 miles, because the rate of charge up to 90% is very fast, but the last 10% is very slow. We usually ran down to between 50 and 100 miles of range, and charged it up to about 290-300 miles, which took between 15 and 20 minutes.
It's not terrible, but compared to a gas engine, it's a good bit slower over time.
On the upside, it forces you to have a more 'easy going' drive.
Stop the damned car and let your family out for fuck's sake.
Just because you can drive >4 hours nonstop doesn't mean you should drive 4 hours nonstop (I did on a solo road trip earlier this year. I forgot a piece of equipment and didn't realize until I was 5 miles out of town, so I had to 'make up time'. It was still a mistake.) Complaining that you can't drive 6 hours nonstop is some form of insanity that I am not qualified to diagnose.
Getting out of the car and getting the blood pumping makes me much more alert for the next hour or two. At first I didn't want to think about that meant about how alert I wasn't for the previous hour. Now it's kind of hard to ignore.
You see so many people in interesting jobs that have an origin story of something that happened to them, a friend, a sibling or neighbor when they were a kid. I just write software, so my stories are perhaps a bit less compelling than the oncologist down the block.
Also, we are talking 6 hours, not "a few". And depending on your height, seat recline, and problems with lower back pain, you can bet for some people, 6 hours unable to stand up can be quite painful. Not, "bamboo shoots under your fingernails painful" but not something anyone would want to go through.
For me, the claustrophobia of not being able to stand up would be quite terrible.
But I appreciate that traditional car makers are finally getting it that people want EVs that are not just golf carts. Too bad this is just another demo but let’s hope they make some of it real.
VW seems to be the only major manufacturer that's really going all in on electric and it's only after wringing their hands from the emissions scandal.
The old automakers seem to only want to do this in the face of bankruptcy.
They are not as big as VW, but that sure should "all in" to me..
I did some digging for my next car and this is what I found: The Chinese owner established newer companies for the Chinese market mostly in China which use their engineering. One of them is a pure EV company.
edit: yeah, found this: https://electrek.co/2018/04/25/volvo-electrification-plan-fu... . And their goal is 50% of sales will be electric by 2025.
And that's probably what they expect to sell. Producing 5.9M electric cars is one thing (and that's not easy on its own), but selling them is the problem.
One, get the government off their back. Two, round up all the 'whiners' lay half of them off and demoralize the rest.
It is said, with only a very small sense of irony, that the only vehicle to come from the Partnership for a New Generation of Vehicles was the Toyota Prius. See, Toyoda thought we were serious, was blocked from joining the partnership (Bush/Gore era protectionism at its finest) and built a brain trust to compete with what turned out to be a bluff. Detroit may be the biggest bunch of learned helplessness foot-draggers there is. It's too haaard. See? We can't do it.
No, it was just a silly physics trick, same as Tesla's Cybertruck pulling the F-150 stunt (which was just because the cybertruck was heavier & therefore had a friction advantage, had nothing to do with being more powerful or anything like that).
As for the train, weighing 1.25 million pounds doesn't mean it took 1.25 million pounds of force to move it, not at all. Just like it doesn't take you ~150 lbs of force to move yourself forward on a bicycle. Wheels are pretty great, and so is a low rolling resistance. A train's steel wheels on a steel track mean super low rolling resistances, and estimates are the Ford only needed around 1875 pounds of force to move that 1.25 million pound train. https://www.roadandtrack.com/new-cars/a28506476/ford-electri...
That's well within the capacity of a bunch of vehicles, no trickery required.
I suspect they didn’t actually build a battery powered truck, not even a prototype or demo.
Instead they just bolted a big electric motor into an existing truck, rigged it up to the crankshaft, and wired it up to power. Lame, if true. But it’s just my suspicion and I don’t know if it’s true. It was clearly a PR stunt timed to take some of the limelight away from Tesla.
And the video of the stunt also has a bunch of angles, including an overhead shot, and there's no hint of anything like a power cord and the truck bed is visibly empty?
But I’ll believe they are sincere when they decommission or fully convert the bulk of their ICE car factories.
1500 HP for an ICE is a multimillion price tag 1500 HP for an EV in 5-10 years will be 1/10th that.
The design of this underlines that. the 1500HP is from just serially adding motors to the axles. It didn't involve a 10 year development cycle for a W-12 quad-turbo'd megaengine.
They pulled 7 motors off the shelf and attached them.
Not happening. The most important thing is not mentioned: weight. The production version can be 1000 lbs heavier than a regular Mustang. This model can cut some of it but more will be added in batteries to get more power. And then there is nothing you can do on the track - can’t fight physics.
Not the first time I see such misleading claims about cars made by tech sites. Linking to articles written by car magazines would be better - they wouldn’t believe the PR so easily.
Edit: I should mention I’m talking about the lap times more than the 1/4 mile times.
Thus, most people tolerate Wranglers because A) they enjoy it, B) they like the image driving one projects. It's really not any different from a Dodge Viper, it's a terrible car that people drive mainly for image, or because melted shoe soles and burned legs are worth it for the fun.
So what happens is, Toyota/Ford/Chevy/Suzuki make a "better" competitor. But hardly anyone buys it because it's a terrible daily driver, and it doesn't have the image of a Wrangler for people to overlook it.
Even Jeep sells mostly comfy SUVs.
It's a real problem that is very prevalent, especially in more rural areas.
I agree with you that building a bunch of electric supercars isn't the ideal long-term plan, but you have to admit that Tesla's roadster and their very fast cars have had an enormous impact when it comes to driving adoption and combatting the negative perceptions around electric cars.
Psychology is a huge factor when you are talking about progress and convincing an entire population to switch their way of thinking.
Like needing to make money? Many of these cars never see production not because of "BS restrictions" but because they can't be feasibly produced for an amount that they think they could sell the car at. This is the equivalent of a hacky prototype. It has a value, and that value is endorsed by management as well.
(not snark: I'm genuinely interested)
Seems good enough for most people daily drivers
