No, Tesla wasn’t “cheated” in the Model 3 headlight safety test by the IIHS

Published

on

With the Insurance Institute for Highway Safety’s release of initial crash test information for the Tesla Model 3 came cries from many in the electric vehicle community that Tesla was “being cheated.” This isn’t entirely true as the new IIHS test removes a lot of cars out of the Top Safety Pick+ rating, the highest accolade the independent safety tester will give a car.

The Insurance Institute for Highway Safety (IIHS) is an independent testing organization funded by insurance companies and some of the banks who back them. The IIHS purchases every car it tests–usually several of each–and tests these vehicles in their highest-available safety configuration. These crash tests usually destroy the vehicles in question, of course, but give an independent, third-party result not otherwise available.

When the IIHS’ initial safety results for the Tesla Model 3 were released, they included ratings for only two of the seven total ratings given to a vehicle. Those ratings, posted to the IIHS.org website, created a lot of response from the community regarding the failure of the Model 3’s headlamps to pass muster.

The tests so far include only the non-invasive, non-destructive tests normally conducted by the IIHS. Namely to crash mitigation systems and headlamps. It’s likely that the next test to see release on the Model 3 will be for LATCH child safety system use, another non-destructive test. From there, crash testing will begin. For that, IIHS needs to receive more Model 3 vehicles (5 in all), the rest of which are on order and expected later this year. Like any other Model 3 buyer, delays in manufacturing have put the IIHS’ ownership of the cars for evaluation on hold.

How the IIHS Conducts Headlight Tests, and Why

The IIHS conducts headlamps tests because, according to the organization, about half of all fatal crashes in the U.S. occur in the dark and many of those are on unlit roads where headlamps are the only thing illuminating whatever’s in front of the car. Although headlights are mandatory and minimum illumination requirements are required by law for all street-legal vehicles, there is a wide variance in how much (and how useful) that illumination can be. Especially with the advent of new lighting technologies.

“Headlight technology has been developing rapidly in recent years. LED and high-intensity discharge (HID) lamps have begun to replace the traditional halogen ones,” IIHS explains on its website. “Many automakers offer curve-adaptive headlights, which respond to steering and swivel according to the direction of travel. Many also offer high-beam assist, a feature that can increase the use of high beams..” These and other variables mean that headlights of the same type on one vehicle can be much worse than they can on another. Even little things like how the lights are focused, what type of light they emit, etc. can change effectiveness.

For those reasons, the IIHS instituted a headlight testing methodology in 2016. Starting this year (2018), these test results directly affect a vehicle’s eligibility for Top Safety Pick+ status. So far in 2018, only a handful of models have received TSP+ ratings. Somewhat surprising for luxury and high-end car buyers is the fact that almost all of those TSP+ vehicles are lower-end vehicles from makes like Hyundai and Subaru.

Testing for headlamps is conducted using a multi-part evaluation using a hypothetical, clear, two-lane road. The tests include measurements in a straightaway, measuring both the length and amount of illumination as well as the amount of glare the lights create for oncoming drivers. Then a gradual left- and right-hand turn and a steeper left- and right-hand curve are measured for a total of five directions in all.

Results are taken from varied distances at 10 inches high and 3-feet, 7-inches high (from the ground) to mimic where the driver is looking (out and down) and where oncoming vehicle drivers are seeing from (higher up). Ratings are then assigned according to how these measurements line up with a hypothetical ideal headlight system. Both low and high beams are tested the same way with the low beams being weighted for scoring as they are used most often in the real world. Vehicles with automatic high beam systems are given more points as the high beams will be used more often.

The Controversy Surrounding the IIHS Headlight Test

The inherent weakness in this IIHS test is similar to that of most of its advanced testing: it’s only tested on the ideal vehicle trim level and options. In other words, the testing is most likely happening on the most expensive model being sold, not necessarily on the most mainstream version of the vehicle. This becomes obvious when the bulk of the Top Safety Pick+ list is comprised of vehicles like the 2018 Subaru WRX.

The WRX is a great car, sure; a personal favorite in fact. But its winning of a TSP+ badge is a little misleading. The volume-selling model WRX is the mid-tier Premium trim, which doesn’t include the LED headlights or the automatic high beam control tested by the IIHS. To get those, one has to go up to the more expensive Limited trim point and add the EyeSight system. That latter point can only come if the buyer of this driver’s car is willing to drop their manual transmission for a CVT. That’s another sticking point as the WRX has a large percentage of buyers who want to shift the gears themselves.

What all of this means is that the 2018 WRX is a great car, but it’s not likely to be purchased in the configuration which the IIHS used to test its headlamps with. Other cars on the TSP+ list are much the same.

The interesting note here is that unlike actual crash tests, the slightly more subjective headlamp tests of the IIHS fall into the non-destructive tests for other safety equipment that, while respected, are also flawed for the same reason: only top-end models tend to have all of that equipment on them. Unlike those other safety items, however, the headlamp tests can hurt higher-end models while lower-end options would ace them. Why? Because LED headlamps, which consistently appear to fail most of the glare testing that the IIHS does, are generally only found on top-end models or luxury vehicles. There could be a lot of reasons for that, but my personal theory is that it has to do with automakers having to find a median between maximum safe illumination and glare due to how reflective LED lamps are designed.

The current IIHS Top Safety Pick+ list includes no midsize luxury cars (which the Model 3 is considered), though the overall midsize car category has five entries. All of them with caveats as to what must be included (usually top trim point items or options). Last year, under the old rules, most midsize and midsize luxury cars made the TSP+ list and Tesla’s Model S failed to make the list in part, again, for headlights.

It’s difficult to say what will happen with the Insurance Institute’s testing going forward. Likely manufacturers will come up with solutions to receive better scores on the headlamps test, perhaps by changing LED lighting designs or gaming the IIHS tests (as they have in the past with the small front overlap).

Tesla has some smart engineers and could probably figure out a way to remedy the lighting problem that’s kept their vehicles from rating high on IIHS tests in recent years. With a mainstream attempt like the Model 3, that could become a very important goal as buyers in the midsize sedan category tend to be safety conscious consumers.

Tesla has a Cybercab problem nobody saw coming

Tesla’s Cybercab line now builds robotaxis faster than Tesla can deploy them, Lars Moravy says.

Tesla’s Cybercab line in Texas can now build the two seat robotaxi faster than the company can put it into service, according to Lars Moravy, Tesla’s Vice President of Vehicle Engineering. “We don’t run every day because the line can run so fast. It’s currently outpacing our deployments,” Moravy said in a new Cybercab deep dive from Munro Live. “So, it’s a bit of a race right now. Who’s going to go faster? Right now the manufacturing line’s ahead.”

Tesla’s official Robotaxi account shared a Cybercab analysis video on X on Monday, calling it a “Cybercab engineering deep dive.” Moravy’s comments go further than what he told analysts on the Q3 earnings call last week, when he said the Cybercab line’s listed capacity of more than 125,000 units a year undersells what it can actually run.

The tour shows where that speed comes from. Tesla’s unboxed process splits the Cybercab into front, rear, side and center modules that are built and tested on their own before they meet on a short final line. That final line has just 25 fully automated stations, which Tesla’s team estimated is a fifth to a tenth of what a Model Y needs. The full line is about 78% automated, the framing line is already at 100%, and the layout uses roughly 50% less floor space per vehicle. The stated goal is “100% automation in 10 second cycle time,” or one finished Cybercab every 10 seconds.

Tesla also deleted the paint shop. Only the side modules are coated, and the exterior panels get their color inside the molding machine. Engineers said the car is designed to run at least 500,000 miles, which matters for a vehicle that will spend most of its day carrying riders.

The battery got the same treatment. The Cybercab uses an 88S6P pack of 4680 cells in a steel enclosure, a first for Tesla, with each module potted separately so a single failed module can be swapped instead of the whole pack. Wireless battery management boards replace a wiring harness, and new contactors are fast enough to drop the pyro fuse entirely. Tesla’s battery director graded the pack an A minus, compared with a D for the Model Y structural pack and a B minus for Cybertruck. Up front, the drive unit runs an 11:1 gear ratio versus roughly 9:1 on most Teslas, since the Cybercab does not need a high top speed.

The deployment side is now the bottleneck Moravy described. Tesla had more than 50 Cybercabs working the Formula 1 weekend in Austin, and Texas records show 463 Cybercabs registered. Tesla said on its earnings call that Cybercab service will launch in Dallas next month, and Moravy said the company is aiming to get Cybercabs to customers by the end of 2026. Every unit built so far has gone into Tesla’s own fleet since the line moved into volume production in April.

Munro Live also asked when it could get a Cybercab to tear down. Tesla’s answer: “Not yet.”

How SpaceX Is raising Raptor’s sea-level thrust while holding engine mass steady

Published

SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.

Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.

This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.

This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.

Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.

Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.

The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.

Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.

For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.

Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.

Tesla Assisted Driving expands to tenth EU country

Published

Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.

Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.

The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.

Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.

In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.

Tesla starts showing how FSD will change lives in Europe

The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.

The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.

These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.

However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.
