Honda sending two NSX racers and new EV concept to Pikes Peak

Honda is always good for a few interesting Pikes Peak entries. In 2015, Acura supplied a 2017 NSX prototype for pace-car duty. This time around, two NSXes will compete alongside a reconfigured version of the company's four-motor electric racecar. Those aren't the 2016 entries above. The one on the right is last year's pace car and the one on the left is a first-gen NSX that did the hillclimb the past few years. The 2016 cars haven't been unveiled yet, but we know that one will be in the Time Attack 2 Production class, which is mostly stock with the addition of items like a roll cage, and the other will be in Time Attack 1. TA 1 allows modifications to the powertrain, additional aero aids, suspension changes, and other tweaks, so expect to see a lot more power and a big wing on the back. The cars will be driven by James and Nick Robinson, brothers who work for Honda R&D in Ohio. Honda will use a version of the four-motor electric powertrain from its 2015 CR-Z Exhibition class entry in a new EV. (We got to drive a non-race tune of this setup in Japan last year.) The 2016 version, which will wear a different body, moves to the Electric - Electric Modified class of last year's frontrunners. We're told this car is aiming for an overall win at the 2016 race; the CR-Z took 11th place overall in 2015. The EV will again be driven by Tetsuya Yamano, a Japanese Super GT driver. Oh, and there will of course be a factory entry or two from Honda's Powersports division. Honda engineer Keith Steidl will ride a 2015 TRX1000 ATV in the Pikes Peak Challenge - Exhibition Powersport class. In the past, Honda has fielded plenty of other neat stuff in the Race to the Clouds. In 2012, it ran an NSX fitted with a twin-turbo V6 from an LMP2 car, and the 2013 race saw the very practical 532-horsepower turbocharged Odyssey minivan join the Exhibition class. The 2016 race marks the Pikes Peak hillclimb's 100th anniversary (but not the 101st running since competition took some breaks back in wartime). We're looking forward to June already.

Massive Airbag Recall Affects Seven Automakers

The recall of faulty airbag inflators supplied by Takata has exploded today to grow to seven automakers. In most cases, only models in certain high-humidity regions were affected because the National Highway Traffic Safety Administration found in its investigation that moisture played a role in determining whether there would be a problem. However, some companies opted for national campaigns. The exact number of affected models for these campaigns isn't yet known at this time. BMW is recalling an undisclosed number of 325i, 325Xi, 330i and 330Xi models from the 2001 through 2005 model years and the 2001-2006 model year versions of the 325Ci and 330Ci for the driver side and passenger side inflators. Only vehicles currently registered in Florida, Puerto Rico, Hawaii and the US Virgin Islands are covered under this recall. Neither Chrysler's filing with NHTSA nor its press release list the specific models affected, but a company spokesperson told Autoblog that at this time it only covers the driver and passenger side inflators for the 2006 Dodge Charger in Florida, Puerto Rico, Hawaii and the US Virgin Islands In most cases, only models in certain high-humidity regions were affected because the NHTSA found that moisture played a roll in determining if there would be a problem. Ford is recalling an estimated 58,669 cars that include the 2005-2006 model years of the Ford GT for the driver and passenger inflators, the 2007-2007 model years of the Mustang for the driver side and 2004 Ranger for the passenger side. It covers vehicles originally sold or currently registered in, wait for it... Florida, Puerto Rico, Hawaii and the US Virgin Islands. Honda is issuing three separate recalls regarding the problem. First, the company is recalling the 2002-2003 model years Civic, CR-V and Odyssey and the 2003 model year of the Accord, Element, Pilot and Acura MDX to replace the passenger's side inflator. This covers all models nationwide. Second, Honda is repairing the passenger's side airbag inflator in the 2003-2005 Accord, Civic, CR-V, Element, Pilot, the 2003-2004 model year versions of the Odyssey, the 2003-2005 model year Acura MDX and 2005 Acura RL. However, only for vehicles located in Alabama, Florida, Georgia, Hawaii, Louisiana, Mississippi, South Carolina, Texas, Puerto Rico and the US Virgin Islands. Owners will be notified in July. Finally, Honda is separately replacing some models' driver's side inflators.

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.
