Elon Musk is one of many people who predicted that the Model Y would be Tesla’s most successful vehicle to date. The vehicle not only has mass-appeal due to its crossover body style and environmental advantages, but it also is Tesla’s most structurally innovative vehicle yet. The Model Y’s underbody rear casting is one of the reasons the car has become recognized as a marvel of automotive engineering, and Musk delved into the details of the project, along with advancements the company intends to make to it by the end of 2020.
During Tesla’s Q1 2020 Earnings Call, Musk discussed the strides the electric automaker had made in the first three months of the year. After outlining Tesla’s somewhat surprisingly successful Q1 despite the coronavirus pandemic, Musk dove into the Model Y and its superior casting design compared to past Tesla vehicles.
“For Model Y, we introduced a revolutionary two-piece rear underbody casting that we are going to be making a single-piece casting later this year,” Musk said. “Meaning like essentially the rear third of the body is cast as a single piece, which is no casting of the size of complexity has never been done before.”
Automotive industry veteran Sandy Munro once said that if Tesla had contracted someone to help produce the early versions of the Model 3, the car would have immediately wiped the floor with everyone. After Munro tore down the Tesla sedan in 2018, Musk and the company realized that there were improvements needed in the build of the car. These started with later builds of the Model 3, but the more significant improvements would be passed on to the Model Y, a sibling of the Model 3 as the two vehicles share 75% of the same parts.
One of the biggest complaints Munro had about the Model 3 was the rear casting. He felt the car was “over-engineered” because it utilized around 100 parts for the rear trunk. However, the Model Y is an entirely different build, and it is something Munro has complimented during recent episodes of his teardown series.
Tesla’s idea for the Model Y was to simplify the build process and utilize fewer parts. But nobody has ever come close to using two parts for rear casting as Tesla did with the Model Y. The decrease in parts helps with the build quality, weight reduction, and production efficiency.
“So, we’re really pushing the envelope on vehicle structural, engineering, and manufacturing. I’m very excited about this approach as it allows us to reduce the weight of the cast and improve NVH. It’s better in every way essentially,” Musk said.
In the past, Munro said that the Model 3’s welding processes looked like “some kind of a science project.” This issue wasn’t present in only the rear casting on the Model 3 but also throughout the entire vehicle. However, Tesla improved on all of these issues with the Model Y, much to the approval of Munro, who has seemed very happy with the build quality of the electric crossover.
The Model Y’s improved build quality and use of revolutionary technology give all indications that the car will end up being what everyone predicted it to be: Tesla’s most successful car in its short but rich history.

Tesla set to win big after IRS adjusts EV tax credit rules
“For purposes of sections 25E, 30D, and 45W, a vehicle is ‘acquired’ as of the date a written binding contract is entered into and a payment has been made. A payment includes a nominal down payment or a vehicle trade-in.”
Tesla is set to potentially come out as a big winner as the IRS has adjusted the rules of the $7,500 EV tax credit slightly.
The $7,500 tax credit for electric vehicles is set to expire on September 30, but the IRS has made a slight adjustment to the terms of the credit that will give consumers a bit more time to buy an EV and receive the discount.
The original terms of the EV tax credit were that delivery of an EV must be completed by September 30. Even if you had made a reservation or put a down payment on an EV, if it did not arrive and take delivery by September 30, the credit would not apply to you.
Tesla is ready with a perfect counter to the end of US EV tax credits
This put some people in quite a tough situation. As wait times for some EVs, especially Tesla Model Y and Model 3 vehicles, continue to be pushed back due to an increase in demand as consumers are trying to take advantage of the credit, some car buyers ordered a car that was not the trim level, paint color, or interior color that they wanted.
However, the IRS has adjusted the terms of the tax credit to enable people to have a bit more time to get the vehicle they want.
Late last week, the agency said that the meaning of “acquired” has been changed, and now, if a consumer has entered a legally binding contract to take delivery of the vehicle, which includes a nominal down payment on the car, they can take delivery after the previous September 30 deadline and still qualify for the credit.
The IRS wrote:
“For purposes of sections 25E, 30D, and 45W, a vehicle is ‘acquired’ as of the date a written binding contract is entered into and a payment has been made. A payment includes a nominal down payment or a vehicle trade-in.”
🚨 HUGE NEWS: The $7,500 EV Tax Credit is EXTENDED (sorta) 🚨
The IRS just updated its guidance:
If you enter a binding contract and make a payment (even a small downpayment or trade-in) before Sept 30, 2025, you’ve officially “acquired” the vehicle.
That means you’ve… pic.twitter.com/7Ciye8OfqB

Tesla could come out as a big winner here because of this. The company is experiencing a lot of demand for its cars because of the tax credit’s expiration, and now that the rule has been adjusted to include orders received by the 30th as long as they’re accompanied by a nominal down payment, some of these high-demand deliveries could leak into Q4.
Q3 is likely going to be a very strong quarter for Tesla, and questions remain about how the company will perform in subsequent quarters since the tax credit is going away. However, this slight adjustment is a big plus for Tesla and other EV makers.

Tesla Semi factory receives giant production equipment
The massive machine was transported to the Semi factory using two diesel trucks and a triple trailer.
Tesla seems determined to kick off the production of the Tesla Semi sometime this year at its Nevada factory.
This was hinted at by the arrival of massive production equipment to the Semi’s manufacturing site near Giga Nevada.
New equipment
What appeared to be a massive stamping machine has been transported to the Giga Texas complex. Spotted by longtime drone operator and Tesla Semi advocate @HinrichsZane, the massive contraption is so large and heavy that a single semi truck and trailer were not enough to move it. Instead, the massive machine was shipped to the Semi factory using two diesel trucks and a triple trailer.
The machine was fully covered in the videos from Nevada, but based on its shape and size, it appears that it is a stamping press for the Class 8 all-electric truck. Tesla is a pioneer in the use of Megacasts in the automotive industry, so it makes sense for the company to use a Giga Press for the Semi’s production as well.
Ambitious goals
The Tesla Semi factory is expected to produce a whopping 50,000 units of the Class 8 all-electric truck annually when it is fully ramped. At that output, the facility would be one of the country’s highest-volume plants for semi trailers, electric or otherwise. In a video posted earlier this year, Dan Priestley, who leads the Semi program at Tesla, stated that the company is looking to achieve volume production over the coming quarters.
This should allow the Tesla Semi factory to mass produce the vehicle by 2026. Tesla CEO Elon Musk reiterated this timeframe recently, when he responded to a post on social media platform X about Microsoft co-founder Bill Gates being bearish about battery electric semi trucks. “Tesla Semi will be in volume production next year,” Musk said in his post, which also included a laughing emoji.
Check out the drone operator’s recent footage of the Tesla Semi factory in the video below.

Elon Musk argues lidar and radar make self driving cars more dangerous
The CEO is not just stating that using sensors like lidar is unnecessary to achieve self-driving.
Elon Musk is taking a firmer stance in the vision vs lidar debate for autonomous driving. In his more recent comments, the CEO is not just stating that using sensors like lidar is unnecessary to achieve self-driving.
Musk is stating that using lidar actually makes self-driving cars more dangerous.
Uber CEO’s comments
During a recent interview, Uber CEO Dara Khosrowshahi shared his thoughts on the autonomy race. As per the CEO, he is still inclined to believe that Waymo’s approach, which requires outfitting cars with equipment such as lidar and radar, is necessary to achieve superhuman levels of safety for self-driving cars.
“Solid state LiDAR is $500. Why not include lidar as well in order to achieve super human safety. All of our partners are using a combination of camera, radar and LiDAR, and I personally think that’s the right solution, but I could be proven wrong,” the Uber CEO noted.
Elon Musk’s rebuttal
In response to the Uber CEO’s comments, Elon Musk stated that lidar and radar, at least based on Tesla’s experience, actually reduce safety instead of improving it. As per the Tesla CEO, there are times when sensors such as lidar and radar disagree with cameras. This creates sensor ambiguity, which, in turn, creates more risk. Musk then noted that Tesla has seen an improvement in safety once the company focused on a vision only approach.
“Lidar and radar reduce safety due to sensor contention. If lidars/radars disagree with cameras, which one wins? This sensor ambiguity causes increased, not decreased, risk. That’s why Waymos can’t drive on highways. We turned off the radars in Teslas to increase safety. Cameras ftw,’ Musk wrote.
Musk’s comments are quite notable as Tesla was able to launch a dedicated Robotaxi pilot in Austin and the Bay Area using its vision-based autonomous systems. The same is true for FSD, which is quickly becoming notably better than humans in driving.
