Tesla adds free titanium underbody shields to Model S to prevent fires

Following a garage fire incident with a Model S EV last year, Tesla Motors quickly sent out an over-the-air software update to adjust how the car charges. Following two on-road fires caused by road debris that struck the underside of different Model S EVs (one in Washington State and the other in Tennessee), Tesla basically said, that it was a random thing, and the car is perfectly safe. The company later sent out a software update to have the car ride a bit higher at highway speeds. Today, Tesla is offering a more substantial solution. Tesla CEO Elon Musk has announced that all Model S EVs built since March 6 have a stronger triple underbody shield that should "bring this [fire] risk down to virtually zero." The company conducted 152 tests using, "every worst case debris impact we can think of, including hardened steel structures set in the ideal position for a piking event, essentially equivalent to driving a car at highway speed into a steel spear braced on the tarmac" and is now confident that there's basically nothing that can break through the new barriers. As you can see here, the shields prevent a concrete block, a three ball tow hitch and a steel alternator from puncturing the car's underside. The new shields should "bring this [fire] risk down to virtually zero." Any Model S owner who wants the new triple shield can ask for it, and even if they don't ask, the structure will be installed whenever the car is next in for service. The three layers of the shield include a rounded, hollow aluminum bar, a titanium plate and "a shallow angle, solid aluminum extrusion." The new shields, "only have a 0.1 percent impact on range and don't affect ride or handling," Musk writes, which means there's no reason for Model S owners not to get the upgrade. You can read all of Musk's explanation below. Tesla Adds Titanium Underbody Shield and Aluminum Deflector Plates to Model S By Elon Musk, Chairman, Product Architect & CEO In 2013, two extremely unusual Model S collisions resulted in underbody damage that led to car fires. These incidents, unfortunately, received more national headlines than the other 200,000 gasoline car fires that happened last year in North America alone. In both cases, the occupants walked away unharmed, thanks to the car's safety features. The onboard computer warned the occupants to exit the vehicles, which they did well before any fire was noticeable.

Tesla delivers 7,579 Model S EVs in Q2, maybe picks Reno, NV for Gigafactory

When it comes to describing its situation, not even Bob Ross could paint a prettier picture than Tesla Motors. The California automaker has had a good few months and announced today that it delivered 7,579 Model S EVs in the second quarter of 2014. That's the most the company has ever delivered in a three-month period, reflecting an expanded market that now spans new countries in Asia and Europe. Tesla also built 8,763 vehicles in that time frame, another record, thanks to getting more cells from battery supplier Panasonic, and says it remains "on track for more than 35,000 deliveries in 2014." Alongside the earlier announcement about the official Gigafactory announcement with Panasonic, the automaker also said today that it has broken ground on a "potential" location in Reno, NV, – validating earlier speculation – while it is still looking at locations in Arizona, California, New Mexico and Texas. Work at the site has mostly stopped for now, however, as the company doesn't want to begin pouring cement until state incentives are in place and a "compelling deal for all parties" has been struck. The ball in Nevada, according to CEO Elon Musk, is now in the hands of the state's governor and legislature. The 7,579 vehicles delivered last quarter continue an upward-moving trend line. In all of 2012, Tesla sold 2,650 Model S EVs. For 2013, the company delivered 4,900 vehicles in Q1, 5,150 in Q2, 5,500 in Q3 and 6,892 in Q4. In 2014, Tesla sold 7,535 Model S EVs in Q1. Add in the 7,579 from Q2 this year, and you've got 15,100 or so, meaning that Tesla needs the next two quarters to average out at around 10,000 each in order to hit the 35,000-vehicle goal. Tesla expects 2015 to be even better, saying that the rate at which its expanding means that its, "annualized delivery rate should exceed 100,000 units by the end of next year." In other words, deliveries for Q4 2015 should be around 25,000 EVs. A few other tidbits from the shareholder letter and today's conference call: Tesla had a loss of $62 million last quarter. The company's Fremont, CA factory is being upgraded to make the Model S and X on the same line and will be up and running next week. Speaking of next week, the first operational Model X Alpha prototypes should be ready by next week. Tesla expects North America to continue to contribute strong demand for its EVs, despite the Model S being available here for several years now.

Cadillac Super Cruise, a hands-off review

Cadillac Super Cruise won't let you eat breakfast behind the wheel, climb in the back seat or any of the other stupid human tricks displayed on YouTube by Tesla owners. It even won't allow the car to change lanes on its own, like Tesla Autopilot. But it's a big step on the road to full autonomy, a huge convenience on long-distance road trips and a substantial technological triumph for Cadillac. In the simplest terms, Super Cruise is a lane-centering enhancement to adaptive cruise control (ACC). But Super Cruise is anything but simple. Its technical complexity — hence its long delay after first being unveiled five years ago — belies its straightforward operation and intuitive user interface, which I discovered on an almost 750-mile, 11-hour drive in a 2018 Cadillac CT6 between Dallas and Santa Fe to test the system. LOADS OF LIMITATIONS First, let's dispense with the details and disclaimers. Super Cruise is standard on the 2018 CT6 Platinum and a $5,000 option on other trim levels. Because Super Cruise is supported by OnStar — an OnStar operator will call to find out if first responders need to be sent in a worst-case scenario — a three-year OnStar Super Cruise Package is included with the system. Super Cruise has loads of limitations that are probably more concerning to GM's legal counsel than they were to me during my long drive. Some are no-brainers, such as not for use in construction zones or for driving on the shoulder. But the system can also be stymied by adverse weather, poor visibility and faded lane markings. Super Cruise only works on freeways with on and off ramps and a center divider. ACC and forward collision warning also need to be engaged, and the system's cameras and radar sensors can't be obstructed. To keep drivers from looking away from the road for too long — and to keep the system active — an infrared camera on top of the steering column keeps an electronic eye on the driver's seat. GM has over 100 patents alone on this Driver Attention System, including an algorithm that triangulates the nose, eyes and ears in case the camera can't see through sunglasses to make sure you're not nodding off. In addition to the car's visible sensors, another major component of the system is something you don't see: mapping software. But not the kludgy kind that powers in-dash navigation systems.
