MotorWeek remembers retro icons, Supra and NSX

It's easy to poke a joke here and there about John Davis, the long-time host of MotorWeek. His voice is so monotonous that, from time to time, if you closed your eyes, you may think it's generated via a computer. But you have to give him and the rest of the show a lot of credit. The program has been on the air for decades, giving people direct, straight-down-the middle automotive reviews.
MotorWeek's massive back catalog of reviews are slowly making their way onto YouTube, and they provide a fascinating chance to look back on how performance cars rank against their contemporaries from back in the day. Two recent additions include the show's old looks at the 1986 Toyota Supra, the dawn of the third-generation model, and the now-iconic 1991 Acura NSX.
Both reviews are interesting in their own way. These days you hear nary a negative word about the original NSX, but MotorWeek isn't afraid to point out a few flaws. And the Supra really shows the progress of suspension tuning in the intervening decades because it has some serious body roll in the corners. Scroll down to check out both videos and get a blast from the automotive past.

Acura ARX-06 race car revealed with V6 hybrid powertrain

There’s a new Acura race car on the block, and itÂ’s called the ARX-06. It replaces the ARX-05, and Acura plans to race it in the 2023 IMSA WeatherTech SportsCar GTP Championship. Unfortunately, Acura makes no mention of the 24 Hours of Le Mans in all of the details provided with the reveal. That said, it sure looks like a race car that could be made to meet all of the regulations to race in the new LMDh Hypercar class. Acura engineered a new 2.4-liter twin-turbo V6 engine that is paired up with a standardized electric system for hybridization. Acura says the 2.4-liter displacement is the smallest displacement engine the HPD team has made for endurance racing yet. It features a 90-degree V-angle, and itÂ’s designed to run on more sustainable low-carbon fuel. "We've gone in a new direction for HPD in the design of the ICE,” said Pierre Descamps, HPD's powertrain design leader for the ARX-06. “It is still a V6, which of course for Honda is well-known, but we have incorporated several new elements which we believe will make best use of the electric MGU and battery pack. Our new engine will rev to the maximum 10,000 rpm set by the rules, so it also makes a wonderful sound!" The new bodywork penned by the Acura Design Studio in Los Angeles sits on an ORECA chassis (one of the four chassis options required by IMSA and the WEC). Acura notes one big change versus the outgoing ARX-05 is found in the rearview mirrors. Designers were able to move them lower on the car, which improved both aerodynamic performance and visibility for the drivers. Similar to years past, these new ARX-06 race cars will be run by Wayne Taylor Racing and Meyer Shank Racing. TheyÂ’ll make their debut at the Rolex 24 at Daytona next year, where the Meyer Shank Racing team took first place earlier this year. Related video:

2021 Acura TLX is the first model with Honda’s new proprietary airbag

When it arrives in showrooms this fall, the 2021 Acura TLX will be the first vehicle equipped with the new three-chamber front passenger airbag design Honda announced last year, reinforcing the automaker’s commitment to infused the sports sedan with state-of-the-art safety bonafides. As explained in the video above, the new airbag was designed and developed by engineers at HondaÂ’s R&D campus in Ohio and auto supplier Autoliv to mitigate the risk of severe brain trauma associated with angled frontal collisions. With its official launch in the 2021 TLX, the airbag will begin to be offered to other automakers through Autoliv. Work on the new airbag design stemmed in part from a 2013 U.S. Department of Transportation study that used MRI scans to look at brain injuries resulting from vehicle accidents and led to the creation of Brain Injury Criteria methodology for measuring brain injuries in vehicle crashes. Accordingly, Honda and Autoliv designed an airbag that does away with the traditional single-inflatable chamber in favor of something likened to a catcherÂ’s mitt, with a central “sail panel” net catching and slowing down the head and directing it inward between the two inflated side chambers. The idea is to better manage lateral forces in a collision that can cause an occupantÂ’s head to rotate severely and at high velocity. Honda is hailing the new airbag as a major advance in airbag design. It follows the companyÂ’s introduction, in 1990, of the first vertically deploying front passenger airbag for the 1991 Acura Legend, a design that became broadly adopted in the industry. Honda is packing lots of other safety features into the 2021 Acura TLX, including knee airbags for driver and front passenger, both contained beneath a panel on the underside of the instrument panel, and eight airbags total, the most ever for the model. It will also come standard with the AcuraWatch suite of advanced safety and driver-assist technologies and AcuraÂ’s Advanced Compatability Engineering body structure, which has been advanced to boost occupant safety by redirecting energy away from the passenger compartment in a frontal crash. Acura says it expects to get a five-star crash rating from the National Highway Traffic Safety Administration and a Top Safety Pick+ rating from the Insurance Institute for Highway Safety.
