NHTSA, IIHS, and 20 automakers to make auto braking standard by 2022

The National Highway Traffic Safety Administration, the Insurance Institute for Highway Safety and virtually every automaker in the US domestic market have announced a pact to make automatic emergency braking standard by 2022. Here's the full rundown of companies involved: BMW, Fiat Chrysler Automobiles, Ford, General Motors, Honda, Hyundai, Jaguar Land Rover, Kia, Mazda, Mercedes-Benz, Mitsubishi, Nissan, Subaru, Tesla, Toyota, Volkswagen, and Volvo (not to mention the brands that fall under each automaker's respective umbrella). Like we reported yesterday, AEB will be as ubiquitous in the future as traction and stability control are today. But the thing to note here is that this is not a governmental mandate. It's truly an agreement between automakers and the government, a fact that NHTSA claims will lead to widespread adoption three years sooner than a formal rule. That fact in itself should prevent up to 28,000 crashes and 12,000 injuries. The agreement will come into effect in two waves. For the majority of vehicles on the road – those with gross vehicle weights below 8,500 pounds – AEB will need to be standard equipment by September 1, 2022. Vehicles between 8,501 and 10,000 pounds will have an extra three years to offer AEB. "It's an exciting time for vehicle safety. By proactively making emergency braking systems standard equipment on their vehicles, these 20 automakers will help prevent thousands of crashes and save lives," said Secretary of Transportation Anthony Foxx said in an official statement. "It's a win for safety and a win for consumers." Read on for the official press release from NHTSA.

Automakers making the commitment are Audi, BMW, FCA US LLC, Ford, General Motors, Honda, Hyundai, Jaguar Land Rover, Kia, Maserati, Mazda, Mercedes-Benz, Mitsubishi Motors, Nissan, Porsche, Subaru, Tesla Motors Inc., Toyota, Volkswagen and Volvo Car USA.

2020 Acura NSX Suspension Deep Dive

The Acura NSX has been a special car as long as I’ve been in the business. The first one came out in 1990, the same year I started my career in automotive engineering. I vividly remember driving one briefly back then when we brought one in for benchmarking. I'd drive it again 22 years later when my previous employer bought a used 1991 example for a long-term test. Reader interest was sky-high and the car was still gorgeous, but the march of time and automotive engineering had clearly left it behind. Then, in 2016, a second-generation NSX emerged, and it was packed with bleeding-edge thinking. It has a 3.5-liter twin-turbo V6, but this new NSX is a hybrid with an electric motor-generator sandwiched between the engine and its nine-speed DCT transmission. Two more electric motors – one for each wheel – power the front axle. There they can add traction, regenerate electricity under braking and dole out hyper-accurate levels of torque vectoring. The carÂ’s tire package was changed from Continental SportContact 5 to SportContact 6 tires in 2019, and numerous suspension re-tuning tweaks came along with them. The result is a lively and well-balanced car that is relentless when driven hard and a pussycat around town. LetÂ’s see what theyÂ’ve got going on under there.   At first glance the 2020 Acura NSX appears to have dual wishbone front suspension. But we canÂ’t tell for sure because that big two-piece brake rotor is in the way. The coil-over shock looks obvious, but a few odd details are apparent even from here.   This view also seems to indicate double wishbone suspension. But the pivot axis (green arrow) between the upper and lower ball joints looks wrong – itÂ’s far too vertical. WeÂ’re missing something. But I would be remiss if I failed to point out a few other things before we moved on. For one, the front drive axle confirms this to be an all-wheel-drive machine. Second, the forged aluminum damper mounting fork (yellow) that envelops the axle is mounted to the lower arm about 75% out from the armÂ’s inner pivot. The spring and damper motion ratio would be 0.75-to-1 relative to wheel movement, with a tiny reduction due to its lean angle. Lastly, just look at the huge cast aluminum upright (white). Beautiful. Normally these are called hub carriers or steering knuckles, and I use the terms interchangeably. But the motorsports-derived term upright is normally applied when the piece is tall and, well, upright like this one.   This explains everything.

Vehicles awarded IIHS Top Safety Pick awards skyrockets for 2015 [w/video]

By practically every measure, passenger vehicles in the US are continuing to get safer. With the year rapidly coming to an end, the Insurance Institute for Highway Safety is releasing its annual list tallying of the scores for the latest vehicles to see how they compare to last year. Judging by the agency's evaluations, the numbers look quite positive. According to the institute, 71 vehicles earned either the Top Safety Pick or Top Safety Pick+ rating so far in its testing for 2015. Among the latest winners, there have been 33 TSP+ awards and 38 TSP medalists. That's a healthy increase over the 22 TSP+ and 17 TSP grades in 2014. The figures appear even more impressive when you consider that it keeps getting harder to earn the + designation. In the latest round of testing, a vehicle must offer some form of front crash prevention automatic braking to get the mark. Previously, just a warning to drivers was necessary. This list also illustrates the ways that automakers adapt to new testing procedures. In 2013 there were 117 TSP ratings and 13 TSP+ awards. Then, the IIHS mandated that to be a safety pick, a model had to score Good in the institute's four crash tests, plus a Good or Acceptable in the small overlap front test. That brought a plunge in 2014 to just 17 TSP grades. With the numbers climbing again, companies apparently have deciphered how to perform better. Some brands especially stood out on this year's list. The IIHS praised Volvo, Mercedes-Benz and Acura for offering standard front crash prevention systems on some models. Subaru received at least one of the awards for all seven of its models. Toyota also had seven, and the Honda brand did too – though the institute counts the two- and four-door versions of the Civic and Accord separately. Check out the full announcement below and a video about this year's winners. The full list can be viewed, here. Safety gains ground: More vehicles earn top honors from IIHS The number of vehicles earning either of the Institute's two awards has jumped to 71 from 39 this time last year, giving consumers more choices for optimum protection in crashes. The number of winners in the top tier - TOP SAFETY PICK+ - has increased by 11 for 2015, despite a tougher standard for front crash prevention. "This is the third year in a row that we are giving automakers a tougher challenge to meet," says IIHS President Adrian Lund.
