IIHS updates overlap test: 2 SUVs get good marks, 9 fare poorly

Vehicles in crashes keep occupants safe by deforming around the cabin in a way that maintains cabin integrity. The Insurance Institute for Highway Safety's moderate overlap test, introduced in 1995, has been a huge contributor to improved safety for front-row passengers in a crash. IIHS President David Harkey said, "Thanks to automakers’ improvements, drivers in most vehicles are nearly 50% less likely to be killed in a frontal crash today than they were 25 years ago." In the 'unintentional side effects' column, crash safety has gotten worse for passengers in the back seats. When carmakers reengineered the front crash structure to protect the driver, more crash forces got distributed throughout the rear. IIHS research claims rear passengers have a 46% greater risk of fatal injury than front-row passengers, but back-seaters haven't benefited from the same upgrades in safety as the front row. The IIHS updated its moderate overlap test to address the issue, putting 15 vehicles through the new regime. Two earned good ratings — the 2023 Ford Escape and the 2021-2023 Volvo XC40 — one was acceptable, three were marginal and nine were rated poor. Every one of the crossovers sampled got good marks for all passengers in the original test. That test sees 40% of vehicle's width on the driver's side impacting an aluminum honeycomb barrier at 40 miles per hour. The updated test puts a crash dummy representing small woman or 12-year-old child in the seat behind the driver, the dummy's sensors and grease paint measuring the effectiveness of the restraints and the forces a human body would need to endure. To achieve a good rating, the "measurements must not exceed limits indicating excessive risk of injury to the head, neck, chest, abdomen or thigh." An institute engineer said, "In real-world crashes, chest injuries are the most common serious rear-seat injuries for adults." The sensors and video evidence showed back seat dummies in the Escape and XC40 endured minimal risk of injuries from excessive crash forces, from submarining under the seat belt, or from unwanted interaction with the side curtain airbag.   The Toyota RAV4 scored acceptable. The second-row dummy also endured minimal risk of injury to the chest and lower extremities. However, the lap belt slipped upward in a way that could increase abdominal injuries, and after the dummy's head dipped during crash impact, the head came back up between the rear curtain airbag and rear window.

Lexus LFA prototype spied lapping the Nurburgring with new bodywork

The Lexus LFA was a real engineering tour de force. Sure, it was stuck in development hell for years, and the 4.8-liter V10's 552-horsepower output wasn't super impressive when it came out, but it integrated a ton of expertise Toyota gained from its F1 team in the early to mid 2000s. Unfortunately, it didn't sell well. Last year, we found there were a few new models sitting on dealer lots, five years after the 500-model run ended. Still, it looks like Toyota may not have given up on the idea of a race-derived flagship for Lexus, at least based on this prototype running around the Nurburgring this week. At first glance, the car pictured here looks like an LFA with the Nurburgring Package and some camouflage on the front and rear fenders. If you look closely, you can see that the fenders are significantly wider than on the standard LFA. Based on the license plate, this appears to be the same car with two different sets of wheels. Lexus may simply be swapping out worn tires, or they may be testing different wheel and tire combinations to fit the wider wheel wells. Anything beyond this is just speculation. There have been rumors of a new flagship Lexus sports car that sits atop the LC 500 and LC 500h. We saw the Toyota GR Super Sport Concept back in January, though that car looks nothing like what we see here. As much as we would love that sweet Yamaha co-developed V10 to carry over, we're not holding our breath. Some sort of hybrid powertrain is almost a certainty. Maybe Lexus and Toyota could pull some tech from its Le Mans-winning TS050 Hybrid race car. Related Video:

Post-earthquake, Toyota prepares to reopen some plants in Japan

Toyota will restart vehicle production at most of its closed factories in Japan next week, but the factories that build the Mirai and many Lexus models will remain closed through at least April 28 and possibly longer. The earthquakes around the city of Kumamoto on the island of Kyushu forced the automaker to stop most of its assembly throughout the country due to a lack of parts supply. Toyota will reopen the plants in phases from April 25 to 28. However, the Motomachi factory with its LFA works, which makes the Mirai, and the Miyata factory will remain closed. These sites also build the Lexus NX, RX, ES, GS, and CT, according to Toyota. The automaker didn't say when production would begin again or how this would affect vehicle supply. "In the update, we received this morning from TMC, they said that at this stage it is too soon to tell what the impact on production will be, so we can't say yet whether there might be vehicle shortages in the US," spokesperson Aaron Fowles told Autoblog. While the quakes were focused on Kyushu, they damaged Aisin Seiki factories, which supplied parts to Toyota plants across the country. The automaker worked with its partner to import the necessary components from China and Mexico, and Aisin started moving molds from the damaged plants to operational ones in Japan, which gets production under way sooner. Automotive News Europe estimates the week of lost production cuts total assembly by 90,000 vehicles. It could cost Toyota the equivalent of $458.2 million to $641.5 million. The company could make up some of the losses through overtime. Toyota says these plans are subject to change because on ongoing tremors in the region, which could cause more damage. Reuters reported there was a magnitude 5.5 aftershock in the Kumamoto area on April 19. So far, the quakes have killed at least 47 people and around 100,000 people have moved to evacuation centers. Toyota to Restart Production on Vehicle Assembly Lines in Japan from April 25 Apr. 20, 2016 Toyota City, Japan, April 20, 2016-Between April 25 and 28, Toyota will restart production on most of its vehicle assembly lines in Japan. On April 17, Toyota announced that, due to parts shortages resulting from the severe earthquakes that struck Japan's island of Kyushu last week, production would be suspended on almost all of its vehicle assembly lines in stages between April 18 and 23.
