Cody Loveland's Corvette-powered NSX claimed by Pikes Peak

Let there be no doubt - racing automobiles can be very dangerous. This unfortunate fact of life has been proven once again today by Cody Loveland, owner of LoveFab, who crashed his Corvette-powered tube-frame Acura NSX on the second turn of the Pikes Peak hill climb course, apparently after a rear upper control arm failed. Cody hit a wall of boulders at high speed, after which the racecar caught fire.
Cody was able to escape the blaze unhurt - minus some missing hair that was singed off in the fire - but the car appears to be a complete mess, as you can see from the image above. The LoveFab Motorsports team has vowed to do its very best to rebuilt the car in time for the competition, but we'd be awfully surprised (and impressed) if that burnt-up hulk were ready for racing with just a few days to rebuild.
We're happy to hear that Cody got away safely, and here's hoping the rest of the competitors get up the hill without incident, or, like Cody, are at least able to walk away uninjured if they don't.

Acura recalls some 2022 TLXs for potential slashed tires

Acura has issued a recall that applies to less than 20 units of the 2022 TLX sedan. The cars included in the campaign were manufactured with tires that may have been damaged by part of a robotic arm while being sorted and stored at a Bridgestone facility in Tennessee. Assigned recall number 22V-950 by the National Highway Traffic Safety Administration (NHTSA), the campaign includes 19 units of the TLX built on September 1, 2022, and Acura estimates that 95% of them may have been built with damaged tires. The company explains that the tires fitted to these vehicles could have sustained cuts and/or tears because a protective plastic shoe located at the base of a robotic arm used to unstack tires exposed a sharp edge by rotating out of position. Damaging a tire's bead area can cause it to gradually lose air; the problem can also manifest itself through unusual noises or vibrations. The tire pressure monitoring system could warn the driver of an issue. The tires in question are Bridgestone's 235/50R18 Turanza EL440. Acura states that it's not aware of warranty claims, field reports, injuries or crashes related to the issue, and Bridgestone says that human workers are now tasked with loading and unloading tires in its facility. Owners of affected cars will receive details about the recall campaign by mail starting on January 30, 2023. They'll be asked to take their TLX to a dealership to get the tires inspected; new tires will be installed free of charge if the ones on the car fall within the affected date range. Drivers who experienced a problem related to this recall and paid to get new tires installed will be eligible to ask Acura for a refund. Related video:

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.
