WEBVTT 00:00.000 --> 00:04.200 In 2017, Tesla introduced its first heavy truck called semi 00:04.540 --> 00:09.940 This was the first move into the semi-truck business. Even though the truck was supposed to be ready sooner 00:10.240 --> 00:13.820 it took Tesla five years to get its first electric cars on the road 00:14.240 --> 00:23.260 Yes, a real production semi-truck has now been given to Tesla. It'll be owned by PepsiCo, which showed off two trucks with Pepsi and Frito-Lay logos 00:23.260 --> 00:27.200 and two other white trucks when Tesla announced that the semi would be built 00:27.800 --> 00:35.040 Elon Musk drove one of the white semis to the, the event where he apologized and thanked everyone for their patients while they waited five years 00:35.040 --> 00:40.860 for the semi to be made. He also talked about why Tesla is making a semi. According to him 00:40.940 --> 00:46.080 it's because semi trucks are responsible for about 20% of emissions, even though they only make up 00:46.080 --> 00:52.300 1% of car sales in the U.S. He also said that living next to a highway where diesel semi trucks 00:52.300 --> 00:57.060 drive around is very dangerous and that the noise pollution they make is very bad 00:57.060 --> 01:02.080 Musk says that's why Tesla semi fits with the company's goal of making sustainable energy 01:02.080 --> 01:08.440 and why it makes a different kind of car than most other automakers. Musk drove one of these trucks right towards the crowd 01:08.780 --> 01:15.880 This was more than just a way to show how it moves. During the show, Musk said that driving the semis a lot like driving a Tesla car 01:16.220 --> 01:21.400 This also includes how well it drives. He said it looks like an elephant that moves like a cheetah 01:21.760 --> 01:27.040 It's quick to speed up and quick to slow down. It has three times the power of a diesel semi-tru 01:27.040 --> 01:34.440 on the road today. Tesla said that the Tesla semis 1,000-volt battery power source will give it a range of 500 miles 01:34.860 --> 01:39.200 Oh, and in the near future, more cars will have the one-kilovolt system 01:39.580 --> 01:45.060 This will be important in the future. It's a plaid triple motor with a plaid double motor frame 01:45.600 --> 01:52.160 Tesla also said that the semis engine, H-Pack, hardware, controls, and software are all based on Tesla technology 01:52.160 --> 01:57.040 and equipment that's already in use, especially its drive system, which is based on 01:57.040 --> 02:10.132 on the dual motors found in the Model S and X plaid and uses a triple motor setup with one axle to speed up At a steady state the motors detach from the axles and let them freewheel which makes the semi more efficient 02:10.692 --> 02:19.192 The single motor takes over and does all the driving on the highway. Musk says that the change from rapid axle engagement to normal driving will be smooth 02:19.192 --> 02:26.152 even though the axles will be coupled and uncoupled. Tesla also showed a video of the truck rolling over things 02:26.152 --> 02:32.032 driving through steep puddles, uneven dirt roads, snow-covered highways, and even washboard roads 02:32.332 --> 02:42.292 to show that it could handle a wide range of driving conditions. Tesla also said that its semis ran between Sparks, Reno, Tahoe, and Fremont around the clock 02:42.292 --> 02:47.312 to make sure they were ready to carry heavy loads. Taking on really heavy loads 02:47.632 --> 02:51.912 Gross truck weight law says that semi can pull up to 82,000 pounds 02:51.912 --> 02:56.132 This is 2,000 pounds more than diesel trucks are allowed, which is a favor for 02:56.132 --> 02:59.872 from the government to make up for the weight of the battery pack in an electric semi 03:00.352 --> 03:07.292 This single highway motor is more than enough to run it regularly. Tesla proved this by taking it through California's donor pass 03:07.292 --> 03:11.712 and filming it carrying its full load and passing a diesel semi while speeding 03:12.112 --> 03:17.112 Regenerative braking is another way that Tesla semi is better than normal ice semi trucks 03:17.412 --> 03:22.372 As it goes down steep hills, the Tesla semi's driver doesn't have to worry about missing a gear 03:22.372 --> 03:26.132 or messing up the Jake break. It also needs less brakes than an ice truck 03:26.132 --> 03:30.872 because of the region. When we reach the bottom of the hill, the brakes are cold, Musk said 03:31.192 --> 03:38.072 That makes the driver and the other drivers on the road safer. Tesla says that the semi has great safety equipment built in 03:38.472 --> 03:42.712 Tesla says that its motor's unique design and its traction and chassis settings 03:42.712 --> 03:48.052 can stop a truck from jackknifing. Musk says that everything just works for the driver 03:48.052 --> 03:56.132 On a single charge, it can go 500 miles. Next, Tesla showed a graph of the 500-mile test drive from Fremont to San Diego 03:56.132 --> 04:18.885 The car pulled just under its 80 pound capacity as a fully production model with no arrow tricks Musk said that Tesla will show the whole eight film without any cuts but tonight he only showed a time version During the 500 trip the Tesla semi never stopped charging but the driver did stop once to use the bathroom and take the required commercial driver break hour 04:19.365 --> 04:26.625 Are you looking for more information? Tesla says that he drove a fully sealed caravan along I-5 about 82 miles per hour 04:26.625 --> 04:33.585 The semi-zerodynamics are a plus in addition to its huge 1,000-volt battery pack for the 500-mile trip 04:34.005 --> 04:38.505 It works together with the trailer it pulls to cut down on drag and increase speed 04:38.965 --> 04:47.245 Overall, the semi-only uses about 2 kilowatt hours per mile. This means that the potential capacity of the battery is 1 megawatt hour 04:47.545 --> 04:52.005 That's more than 33 times as much as the average home uses in one day 04:52.005 --> 04:56.605 Not just because of the driver's seat, but also because of the driver-centered design 04:56.605 --> 05:01.825 9, Tesla's ideas go beyond just tech. The driver is in mind when the car was made 05:01.965 --> 05:06.825 but not just because the seats are in the middle. First, it has standard wireless charging 05:07.025 --> 05:11.845 a USBC port for mobile devices, and easy places to store these devices 05:12.305 --> 05:16.145 The regular Tesla semi is also bigger than a normal day cab truck 05:16.265 --> 05:22.985 which, if you've never been inside one, may be shockingly cramped. Anyone taller than 6 feet will be fine 05:22.985 --> 05:32.345 It also has features to make it easier to get work done, one-button rear dump to help load trailers. This isn't a particularly new idea since many 05:32.345 --> 05:37.745 heavy trucks dump or kneel to load trailers. It also has built-in safety checks that the driver 05:37.745 --> 05:43.285 can use from the cab to help pass safety checks while on the road. Lastly, the semi has a spherical 05:43.285 --> 05:48.765 steering wheel, which is different from Tesla's most recent passenger cars. However, it still has 05:48.765 --> 05:54.085 the standard Tesla wheel touch controls and scroll wheel. It also has two tablet monitors with 05:54.085 --> 05:58.845 different views, so the driver can keep an eye on the load, check for blind spots, and 05:58.845 --> 06:19.237 use navigation without having to change views on a single screen. Instead of putting both screens in horizontal mode like the S or X the steering wheel is in the middle of both screens Version 4 of Tesla charging system is 1 megawatt and will be available next year Another surprise that Tesla showed off was the new version 4 charging system 06:19.417 --> 06:27.457 which is a 1 megawatt DC charging system with immersion cooling. This system has three times the power density of a non-immersion cooled system 06:27.457 --> 06:33.217 and also lets the cord be thinner. Tesla also said this charging will be used on cybertruck 06:33.217 --> 06:44.217 and will be available at Tesla superchargers next year. semis can charge in a reasonable amount of time, which Tesla has said before means they can charge 70% in just 30 minutes 06:44.637 --> 06:49.577 In the most current update, Musk did not explain or specify how long it takes to charge 06:49.837 --> 06:55.957 As we've already said, one megawatt is almost 33 times more energy than the average home uses in a day 06:56.097 --> 07:01.197 and it's likely more than one semi will be charging at any given charging spot at the same time 07:01.597 --> 07:06.357 Musk, on the other hand, said that Tesla could make up for this by using solar energy and 07:06.357 --> 07:13.457 building power centers that would release stored energy when it was needed. Musk also suggested starting to make nuclear power again 07:13.617 --> 07:18.897 but these cars will need a lot of energy to charge, and it's not clear if Tesla supercharging stations 07:19.097 --> 07:22.617 let alone the power networks that will serve them, will be able to handle it 07:22.997 --> 07:28.997 Will there be more than just PepsiCo? Now that the first deal with PepsiCo is started production and delivery 07:29.197 --> 07:33.497 the question is whether or not other transport and goods companies will do the same 07:33.497 --> 07:43.657 Since the Tesla semi was first shown off five years ago, at least one order has been placed by Anheiser-Busch, Walmart, UPS, and 12 other North American companies 07:44.137 --> 07:49.017 Other European brands have also said they'll order semis for their teams around the same time 07:49.577 --> 07:53.197 Now that Tesla has shown the production form, will other brands follow 07:53.497 --> 07:59.477 How many other owner-operators will buy an electric semi-truck that is as easy to drive as a Tesla 07:59.477 --> 08:04.877 We'll have to wait and see, but if Musk's claims about saving money on gas and brakes are true 08:05.177 --> 08:09.677 and Tesla can build and ship a lot of these, it's hard to argue against the investment 08:09.877 --> 08:14.757 at least for short and medium distance hauling jobs.
