Chevrolet Unveils 200-Mile Bolt EV At Detroit Auto Show

MikeChino writes Tesla, take cover – General Motors is taking aim at the affordable electric vehicle market with the brand new Chevy Bolt, which was just unveiled at the 2015 Detroit Auto Show. The all-electric vehicle is able to travel 200 miles on a single charge, and it will cost about $30,000 – which puts it squarely in the ring with the Tesla Model 3. According to the article, "Chevrolet is planning to launch the Bolt EV in 2017, and inside sources say that it will be available in all 50 states."

      Please stop spreading misinformation. There is a driving scenario where a) the vehicle is operating in "charge sustain" mode (i.e. battery is flat, or user has selected "Hold") and b) the vehicle is being operated at relatively high speeds (> ~50 km/hr) with low torque requirements (i.e. roughly constant speed). In this very specific driving scenario, you are correct, there is a mechanical connection between the gas engine and the wheels.

      However, in all other driving conditions, there is no mechanical connection. In stop-and-go traffic around down or on the highway during rush hour, in charge sustain mode, the gas engine will drive a generator motor, the electricity from which feeds the traction motor and the battery -- this is a series hybrid configuration. Under any driving condition while in "charge deplete" mode (i.e. drawing from the battery), the gas engine never turns on, making it operate purely as an EV. An important point to note is that the vehicle is able to achieve is full performance capabilities -- acceleration, top speed, and braking -- under purely electric propulsion without the gas engine ever turning on. This is the distinction that makes it more than just a series+parallel hybrid.

      The general problems are the design trade offs that occur any time when there is a direct mechanical linkage between the internal combustion engine and the drive train. The reason is because you are most likely forced to use an engine that has some greater variability in torque and rotational speed than would be necessary if there was no direct linkage.

      Why does this matter? Because it likely reduces overall system efficiency. For maximal efficiency, you are better off having an engine that is custom paired to the generator, meaning that it runs at a very confined torque range and rotational speed to maximize generation of electricity since electrical generators generally work most efficiently at a specific rotational speed and fall off on either side of that speed.. This of course requires that the amount of electricity generated is enough to drive the electric motors alone (i.e. no battery support in the case that the battery is dead). By adding a direct mechanical linkage, the engine is likely to require operation over a wider range of speeds and torque and is less likely to be optimized.

      Based on the specific conditions that you had indicated for when the mechanical linkage occurs (constrained torque scenario), it is possible that they were able to marry the best of both worlds in terms of efficient engine design, but I'm skeptical. Also, this setup would presumably mean that the individual drive wheels are not directly driven by electrical motors and that there is a drive shaft and differential of sorts in between the electric motor and the wheels.

      Why all this "likely" talk? The video I linked to is the first in a series of presentations by Pamela Fletcher, the head of GM's electric drive train division. She talks about the trades and the systems design that led to what we have now; it's really pretty interesting. Basically they started out with exactly what you want: a traction motor driving the wheels directly, and a generator motor attached to an ICE, with only electricity flowing between them. Then they said "hey wait a second, electric motors are less efficient at higher RPM; can we use this second electric motor to reduce the speed of the first through a high gear ratio, thus improve overall efficiency at high speeds? By golly we can!". That is why the generator motor is able to couple to the traction motor at high speeds to drive the wheels together.

      The fact that there is a mechanical linkage when you then enter charge deplete mode is actually a by-product of wanting the ICE connected to the generator motor, but also wanting the generator motor connected to the planetary gear set. It's not something that was baked in from the start as a "core ideal" or goal, it was something that came about as the result of a number of other trades.

      The biggest downside to going this route is that there are intermediate periods of time where the ICE will be free-wheeling, which means they required a throttle assembly. If the generator motor were always attached to the ICE output shaft, you wouldn't need a throttle, because you could just cap the RPM using back torque from the generator motor.

      Based on the specific conditions that you had indicated for when the mechanical linkage occurs (constrained torque scenario), it is possible that they were able to marry the best of both worlds in terms of efficient engine design, but I'm skeptical. Also, this setup would presumably mean that the individual drive wheels are not directly driven by electrical motors and that there is a drive shaft and differential of sorts in between the electric motor and the wheels. This likely also reduces overall efficiency than a direct drive scenario (i.e. electric motors directly connected to the individual drive wheels).

      After warming up, the ICE is generally operating at wide-open throttle (peak efficiency for a given power output). Its RPM is capped by the torque put on it by the generator motor and, when in that situation, the planetary gear set. By adjusting the flow of current (and thus the torque) between the two motors, and using the battery as a buffer for transient events, they can adjust the output power of the engine simply by adjusting its output RPM. Keep in mind that the electric motors are not lossless and neither is charging/discharging the battery. Any power going from the ICE output shaft to the drive shaft mechanically is not subject to the losses of going through two electric motor

Federal minimum wage is actually $7.25 per hour, which would add up to $1160 per month.

    I hope that this effort of GM's succeeds at least well enough for them to continue R&D into EV's, but there are 2 significant problems I see that they'll need to overcome:

    First, they'll need a high-speed charging network that will allow for long-distance road trips. Public charging infrastructure is too slow to realistically allow for a trip that is further than what one can do on a single charge. Granted, with 200 miles instead of 40, this is significantly better than what's out there now, it's still not good enough for someone that wants to occasionally take their car on a multi-state road trip. Tesla's supercharger network gives them a competitive advantage, and GM will need something similar. Tesla has said that they are willing to share access, but it has to be on their terms. If GM is willing to buy in on that, we might see a Bolt capable of using Tesla superchargers - this would solve this issue for GM.

    Second, the established dealer network has no interest in selling EV's. Most of their profits come from after-market service, and EV's have (theoretically) significantly less service needs. To this end, the dealers are motivated to push traditional ICE's over EV's in virtually every case. This is the major reason why Tesla does not use the traditional dealership sales model. No car salesman will direct you to a Bolt - you'll only get one if you come in specifically wanting one and push past their sales tactics to get you into something else. Buyers of the Nissan Leaf have reported resistance to and sometimes outright hostility from dealerships over wanting to purchase an EV. Unless GM is somehow able to break the dealership cartel and begin direct sales themselves, this issue won't be overcome anytime soon.

    Another thought: at $30,000, I strongly suspect it is priced as a loss-leader, meaning it is being sold under cost. Tesla needs the economies of scale of their massive battery factory they call their "gigafactory" now under construction in Nevada in order to achieve a $35,000 price point for the Model 3. It seems unlikely to me that GM has managed to bring the cost down so much without a gigafactory of their own.

There's every likelihood that one of these new German diesels (with their myriad failure-prone sensors and crappy wiring harnesses) will have you constantly headed back to the dealership for repairs, at least until the factory warranty runs out.

    Even if the answer is a giant coal power plant, that coal power plant is much more thermally efficient than your Golf TDi. The cold TDi's engine is around 34% efficient (and that's ignoring the fact that a petrol car has a much more significant gear box and transmission than an electric, and hence loses more there, it's likely to only about 15% efficient at the wheels). Meanwhile thermal efficiency for power plants is around 60% and electric cars have thermal efficiencies around 80%, so in total about 48% thermally efficient at the wheels. That is, for the same power, an electric car will burn 3 times less fossil fuels, even if you assume that it is 100% powered by fossil fuel power plants.

    "Mean" is the same as "average" . People who think otherwise have learned just enough math to be dangerous but not enough to do anything useful.

    Possibly you wish to invoke the "median."

    No one will admit to it,... but either OPEC is trying to destroy the US Shale-Oil business by pushing the price of oil through the floor.

    It's really weird that you feel like no one will admit to it, and that it's speculation "on your part". This is widely known. It is not a secret. It is a workable and working strategy. This is not a conspiracy theory, it is reality. I've seen probably a dozen articles on it, and it's the topic of discussion on both NPR and conservative talk radio. Rest assured, the price will rise again.

    The saudi's paid some very smart investment analysts to determine the burn down rate of new wells, pipelines and capacity in north america, and compare that to global markets. Their reserve value will outlast the shale oil investment costs, you can be sure. They also decided to punish the other OPEC states for previous non-cooperation in price fixing at the same time, and this will cause those competitors to deplete reserves faster too. It's a triple win for them. Win/win/win.

    I'm a pretty big fan of TDI myself (go tdiclub!), but reality can be harsh. I purchased a 2000 beetle three years ago, at 220,000 miles. The first owner probably didn't like it, sold it after two years, with at least ten shop visits. I forget the exact mileage and cost, but not all of it was covered by warranties. The second owner had it for the intervening years and maybe 200,000 miles. She took it the dealership when necessary, I think the repair bills over the first 12 years totalled $16,000.

    I finally broke down and paid to have work done last week. I wont count the brakes since that isn't TDI related, but the thermostat was $250. (heat wave! now I'm not freezing in Michigan's zero degree weather. Since VW doesn't install a temp gauge, it took me two years to realize this was a problem.) I could still use new injectors. Maybe the intake manifold could be cleaned. DIY oil changes cost twice as much as my older gas vehicles. There are several parts on the engine that might fail, and cost $1000 to $2000 to fix (turbo, intercooler). I'm burning a quart of oil every six weeks.

    My Bug has the ALH engine, which I love for being able to use B100 and maybe other alternatives. The newer engines are more complex. The recent kicker has been been gas dropping to $1.90/gal, while diesel is generally $3.40 here. I used to buy diesel at similar prices, or at most 20 cents more. Maybe TDI makes more sense for people that put on crazy miles (25,000 per year?) but I wouldn't really recommend it to a normal, non-enthusiast american.

    My Beetle is probably averaging 10 cents per mile for fuel (over the 40,000 miles I've driven). That was about the same as my wife's Aveo, until the gas price drop. Now she is probably paying 6 cents per mile fuel.

    (PS - I had four new cars with gas engines, I sold them at 170k, 220k, 190k, 230k, all without any major engine issues)

    Exactly right, but your sensible viewpoint doesn't belong anywhere on a blog site, apparently. No, you can't completely describe the Volt as a plug-in hybrid, EV, series or parallel hybrid, or whatever--it's a Volt and there's nothing else exactly like it.

    I read this forum having come from other EV forums where readers are complaining endlessly that the Volt isn't a true EV, that it has far too limited range, that it was designed as a parallel hybrid and should've been a series hybrid, etc. Folks. This is all new stuff. If you want to change the world, stop posting drivel that drives away readership.

    And BTW I'm sure GM would've loved to have released an EV in 2010 with 200+ mile range, one hour charge times, and a sub-$25k price. The reality is that it wasn't practical in 2010, and may be only barely practical today given the economics involved and the state of the technology.

    The Volt is a great stop-gap. It gave us something to buy these past four years while we wait for more advanced EV's to become feasible and hit the market. The drivetrain is complex, but apparently has a very low failure rate. The ICE will run frequently or continuously in extreme conditions, but most drivers can expect lifetime averages well over 100 MPG driving in real-world conditions. Why can nobody simply call this what it is: A technical coup for GM.

    I drive a Volt. You've probably seen the back side of it if you drive around San Diego. Yep, it's very zippy in the 0 to 50 mph range. It is pretty rare that the engine drives the wheels. I have had it for 2 1/2 years and have 50k miles on it. The finish, interior and performance are the same as the day I bought it. GM did an outstanding job on this vehicle. The maintenance costs are extremely low. I've changed the oil twice and not because the car was telling me to. I just got uncomfortable not changing the oil. The brake pads are at 99%. They rarely get used. After driving around, you can touch the brake pads and they will still be cold. The engine in the Volt is really more like a generator. Nothing too complicated about that. The only problem this car has is the ignorant who put forth a worthless opinion that others then parrot as fact. I'd buy another Volt in a heart beat. Oh wait, I did, for my wife. It drives as well as mine does.

  33. car prices have been decreasing by schlachter · · Score: 5, Interesting

    While that makes sense, the claim of the article is that car prices are rising relative to household income -- in other words, it implies that the average new car used to be affordable, that it now is no longer so, and that it's continuing to become increasingly unaffordable.

    Actually, car prices have been increasing at a MUCH lower rate than inflation or other costs due to automation of factories, better designs, electronics prices dropping, etc.

    For example:

    In 1996 I bought a NEW Honda Accord for $22,500
    In 2015 you can buy a much better equipped Honda Accord for around $25,000
    That's a 10% increase over 19 yrs! It's actually a decrease in price if you consider what you're getting for the cost (i.e. much more HP, MPG, safety, etc)

    For reference...in that same time period, movie ticket prices have doubled, gas prices have tripled, housing prices have doubled.
