GM Korea set to import 5,000 EVs in 2018

GM Korea will import around 5,000 Chevrolet Bolt electric vehicles (EVs)
next year, aiming to take the lead in the nation's increasingly competitive
eco-friendly car market.
A government source said on condition of anonymity GM Korea has a plan to
import and sell around 5,000 Bolt EVs next year, and a GM Korea official
partly confirmed this.
"I can't comment on the company's sales plan for next year at this point,
but it's true we said 5,000 when the government asked about it," the GM
official said.
"We were very surprised at the Bolt EV's explosive popularity earlier this
year. We started receiving pre-orders for the model on March 17, and all 400
cars available were sold out in two hours. I believe the EV model's
competitiveness is unparalleled in the nation's eco-friendly market."
According to the Korea Automobile Importers and Distributors Association,
10,075 EVs were sold between January and October this year, and GM Korea's
plan to import and sell 5,000 Bolt EVs next year implies its ambition to
take a big chunk of the market.
A senior engineer of General Motors demonstrated his confidence in the Chevy
Bolt EV's success.
"With its drive range of 383 kilometers, you don't need to charge the Bolt
EV every day. I also drive the Bolt EV in the United States and charged it
only once a week. With a model like the Bolt EV, you don't need to look
around to find charging stations every day," GM Chevrolet Bolt EV chief
engineer Michael Lelli said.
"The model is a revolutionary product that was developed based on the deep
expertise of GM engineers worldwide and years of customer feedback and
innovative partnerships. With its affordability, long range and exciting new
technologies, it will enable more customers to experience a true EV life."
The Bolt EV is priced at 47.79 million won, but end consumers would pay less
than 30 million won thanks to government subsidies for EVs.
Apart from the model's affordability and drive range, the Bolt EV's
performance was also proven to dispel many misgivings about EVs _ slow and
boring machines with batteries that may suddenly discharge while driving.
Mounting a 150 KW motor that can produce a maximum of 204 horsepower with
36.7 kg.m torque, the Chevy Bolt EV can reach 100 kilometers per hour in
less than seven seconds. The popular BMW 320d sports sedan takes more than
seven seconds to reach 100 kilometers per hour.

Musk: Tesla pickup could have "gamechanging" feature.
Tesla Inc. will build a pickup truck soon after producing electric crossover
vehicle Model Y, CEO Elon Musk said on Tuesday.
"I promise that we will make a pickup truck right after Model Y. Have had
the core design/engineering elements in my mind for almost 5 years. Am dying
to build it," Musk wrote in a Twitter post.
When asked if the truck would be in the same size class as the Ford F-150,
Musk responded:
"Similar total size. Maybe slightly bigger to account for a really
gamechanging (I think) feature I’d like to add."
The Model Y, to be built on the same platform as the Model 3 sedan, was
tentatively scheduled to begin production in mid-2019, Reuters reported in
June.
The electric vehicle maker first announced plans for a pickup truck last
July, alongside a "master plan" to develop a commercial truck, a public
transport bus and a compact SUV.
Musk had said in April that the pickup truck would be unveiled within 18 to
24 months.

I take it youi're talking about the Sunrise? I was thinking of the Force. I'd be surprised if Worden used the Geo / Suzuki transaxle in the Sunrise, rather than the more efficient Force transaxle. However, I'm sure you know more about that than I do. Solectria / Brusa designed a least 2 custom transaxles that were used in the Force. The AT1000 was driven by a cogged belt and was used until (IIRC) around 1996. The belt was noisy, so they built the AT600. It was gear driven directly from the motor, and was normally sold as a unit with the motor. In the early 1990s, NPR interviewed a Solectria rep (I don't recall who) for a feature about the Force. Unfortunately, I wasn't able to grab a dub of the program when I heard it, so I have to go on memory. They actually drove the Force. Maybe the interviewer commented on the lack of a gearshift, I don't recall, but I do quite clearly remember the Solectria rep saying "we do remove the [factory] transmission." That said, a small number of early Forces were built using the Geo / Suzuki factory manual gearbox and a rather underpowered BLDC motor. I think that Solectria eventually upgraded most or all of them to induction motors and the in-house transaxles, but there may be a scant few, still scooting around out there on the roads. Regardless, my point stands. James Worden was (probably still is) obsessed with efficiency. Certainly some of his fine-tuning, such as adding flat belly pans to his EVs, was cheap to do and produced outstanding returns. Junking the stock Geo Metro transaxle for a pricey custom-made one might not have been as cost effective, but I still admire him for his focus on efficiency.

Good luck buying those hyper-efficient PV panels without breaking into Fort Knox! If you can afford that kind of money, though, why not book a flight on Musk's SpaceX? Just reach out and snare an old, dark, disused comm satellite or two as you sail by. :-) Even if you could afford the PV, 60 feet (longer than a semi trailer) is 2.5 times the length of a nice-sized US 2-car garage.

Rush Dougherty via EV wrote: If you're maximizing your 'efficiency' then why use plywood? Nobody that is trying to increase strength and lower weight using plywood anymore, they use Carbon Fiber. So spend a few extra $k and invest in a trailer that will weight 10lbs to hold your 2kw array. Quality plywood has a pretty good strength-to-weight ratio, and it's easy to work with. It's kind of a natural composite. Carbon fiber is stronger, but also brittle, expensive and harder to work with. Whether it makes sense depends on your budget, the design of the trailer, and how rigid a support the PV panels need. With a huge lightweight trailer, I suspect you'd want to avoid glass panels in favor of something a lot more flexible, in which case plywood might work OK. But overall, I still think I'd avoid a trailer, and put them on the vehicle itself. -- Whether we or our politicians know it or not, Nature is party to all our deals and decisions, and she has more votes, a longer memory, and a sterner sense of justice than we do. -- Wendell Berry -- Lee Hart, 814 8th Ave N, Sartell MN 56377, www.sunrise-ev.com ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)

Small lightly loaded trailers with little wind resistance can add 50-80 Wh/mile. Taller/heavier trailers can double vehicle energy consumption.

Re: [EVDL] Solar trailer calculation
If you're maximizing your 'efficiency' then why use plywood? Nobody that is trying to increase strength and lower weight using plywood anymore, they use Carbon Fiber. So spend a few extra $k and invest in a trailer that will weight 10lbs to hold your 2kw array.

Re: [EVDL] Solar trailer (a 1000-to-1 waste)
I agree 100%. Folks forget that it takes significant energy to tow even a small trailer. Much more than one would think. Probably more energy than the panels produce, especially at highway speeds. Best to leave them on the roof of your house, or put them on a "solar shed" for your car to park under at work. Bill D.

The whole DIY build would be plywood on a light weight trailer. When you're aiming for efficiency, I think a trailer is a liability. It would be better to shape the vehicle itself to have as much roof area as possible, and use as little energy as possible. Essentially what you see in cars like Stella, or the solar raycers. The vehicle can also be specialized for your particular situation. How far do you drive in a day? Maybe you can size the PV panels and batteries so it can work for you with little or no grid charging. Maybe the PV panels can unfold when parked, to significantly increase their area. -- Whether we or our politicians know it or not, Nature is party to all our deals and decisions, and she has more votes, a longer memory, and a sterner sense of justice than we do. -- Wendell Berry -- Lee Hart, 814 8th Ave N, Sartell MN 56377, www.sunrise-ev.com ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)

Re: [EVDL] Solar trailer
Yes the units cancel. I brought the units along anyway to make the parallel to my base numbers more obvious. Also, gen 1 Leaf curb weight is around 3300 lbs; in comparison a gen 3 Prius is about 3050 lbs and a Model S is about 4500-4900 lbs depending on pack capacity.

Not quite; he kept the Geo transaxle, but "gutted" it so all it had was 2nd gear. It then ran lighter weight oil (not the usual 90w gear lube). That's what James Worden was all about. He obsessively tuned efficiency in his EVs. That's why he routinely won the Tour de Sol, and also part of why his cars were too expensive to ever sell well. That's him! Efficiency was his goal; and he was good at it achieving it. The cars were expensive simply because they were hand-made in such low quantities. The efficiency enhancements added little to their cost, but helped them sell better. So they were probably a step in the right direction. I think Worden saw the GM EV1 as his real competition. It was another exceptional EV that was designed from the ground up for efficiency. Neither car was the "same old thing" -- an EV conversion of a standard ICE vehicle, with an old forklift motor and off-the-shelf batteries. Instead, they showed us what an EV can really do if designed right from the very beginning. I think the genius of Bob Rice was to realize that a) scratch-built EVs really *can* be built cheaper and simpler than ICEs, and b) Worden's improvements could be applied to *any* EV that was built from scratch. -- Whether we or our politicians know it or not, Nature is party to all our deals and decisions, and she has more votes, a longer memory, and a sterner sense of justice than we do. -- Wendell Berry -- Lee Hart, 814 8th Ave N, Sartell MN 56377, www.sunrise-ev.com ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
