Tesla Semi: electric lorry launch pushed back to 2020

Tesla boss Elon Musk has announced that the launch of the brand’s Semi electric lorry will be delayed until 2020, citing an already strained battery supply for production of its range of EVs.  Speaking at the firm’s annual shareholders meeting, Musk said his company would strive to ramp up battery production as quickly as possible, going so far as to suggest a venture into mining could be a possibility.  Despite the delay, customers are still able to reserve Semi models. Existing customers include large companies such as Walmart, UPS and FedEx, but it is remains to be seen whether the delayed release will discourage further investment in the zero-emissions truck.   Such bottlenecks are no new phenomenon for Tesla, with Model 3 production brought to a halt in early 2018 by worker shortages and software issues. The brand’s fourth model, the Jaguar I-Pace rivalling Model Y, is due on the US market next year, with Musk aiming for an annual output of 2000 per week by September 2020.  The Semi electric lorry will be capable of travelling up to 600 miles on a single charge, even when fully loaded, company CEO Elon Musk has claimed. According to Electrek, Musk said during a conference call last year that he was “optimistic” the Semi would beat the 500-mile range announced at its reveal in 2017. His claim followed Daimler lorry division boss Martin Daum’s suggestion that the Semi’s statistics “defied the laws of physics”. The Semi with the 600-mile claimed range costs $180,000 (£132,720 at today’s rate) in the US. A lower-spec variant with a 300-mile range will be priced from $150,000 (£110,565). Prices for diesel lorries in Britain start at about £85,000 by comparison. During its November 2017 reveal in Hawthorne, California, where Tesla also showed a new Roadster sports car, Musk said the Semi, which was previously referred to as the Tesla Truck, was capable of accelerating from 0-60mph in 5.0sec. He also said it was able to hit 60mph in 20.0sec when the trailer is fully loaded with 80,000lb (almost 36 tonnes) of cargo. This beats the average sprint time for regular diesel-powered rivals by around 40 seconds. The Semi’s energy recovery systems are claimed to be capable of recovering 98% of kinetic energy to the battery. For regular charging, the lorry can be connected to Megachargers – a new high-speed DC charging solution – that are said to add about 400 miles in 30 minutes and can be installed at origin or destination points, much like the existing Superchargers. Efficiency is boosted by a low wind resistance, with Tesla claiming the Semi has a drag coefficient of 0.36Cd. It states that most of its competitors are closer to 0.65Cd. Tesla has refrained from going into further detail about the lorry’s drivetrain and battery but has revealed that the vehicle features advanced autonomous technology to prevent jackknifing of the trailer. Onboard sensors are installed to detect instability and can adjust torque sent to each wheel and independently actuate all brakes to avoid jackknifing. Additionally, surround cameras provide autonomous object detection and reduce blindspots, alerting the driver to safety hazards and obstacles. The lorry also introduces a new Enhanced Autopilot system, with automatic emergency braking, automatic lane keeping, lane departure warning and even event recording. The Semi can travel in a convoy, allowing one or several Semis to autonomously follow a leader. Alongside the claims for performance and safety, Musk said the Semi would provide users with massive savings. Figures produced by the company state that owners “can expect to save $200,000 or more over a million miles based on fuel costs alone”. These production issues related to supply difficulties with the Model 3. They caused the reveal of the Semi to be delayed by several

Autopilot was on when Tesla hit semi trailer in fatal crash: safety board

A Tesla Model 3 involved in a March 1 fatal crash in Florida was being driven by the vehicle’s semi-autonomous Autopilot system and the driver’s hands weren’t on the steering wheel, according to the U.S. National Transportation Safety Board. The driver was killed when the car slammed into the side of a semi-truck that was crossing a highway in Delray Beach, the NTSB said in a preliminary report released Thursday. The driver apparently wasn’t steering in the eight seconds before the collision, according to NTSB. “Preliminary vehicle data show that the Tesla was traveling about 68 mph (109 km/h) when it struck the semitrailer,” the report said. “Neither the preliminary data nor the videos indicate that the driver or the ADAS executed evasive maneuvers.” ADAS refers to Tesla’s advanced driver assistance system. The NTSB used video from a nearby surveillance camera showing the collision and the video devices that Teslas use to help them steer and perform other functions. “We are deeply saddened by this accident and our thoughts are with everyone affected by this tragedy,” Tesla said in an emailed statement. The company informed NTSB and the National Highway Traffic Safety Administration about the Autopilot activation after reviewing the car’s computerized data log, the company said. The crash is the latest Tesla accident under investigation by the NTSB and is strikingly similar to 2016 case in which a Model S hit the side of a truck without braking. In that fatal collision, the NTSB found that the design of Tesla Autopilot system was partially responsible for the crash and issued two recommendations to the company and other manufacturers to improve the safety of such partially autonomous driving tools. Among the NTSB’s findings was that the car’s sensors weren’t designed to identify the side of the truck and, therefore, didn’t slow the car. The NTSB preliminary report on the March 1 collision doesn’t spell out what the car’s sensors detected as the vehicle approached the truck. The safety board is also looking at another fatal crash involving Autopilot in 2018 in California. In that case, a Model X struck a concrete highway barrier, killing the driver. NTSB investigators are also probing how the electric Tesla’s batteries behave after accidents following several
