2021 Acura TLX outed in European patent images

Acura brought its Type S concept to last year's Monterey Car Week as a glimmer of what we could expect from the all-new TLX coming next year. Since then, we've had better glimpses of the sedan in unintended leaks, the first in Acura's own infotainment system, now in patent images from the European Union Intellectual Property Office. Discovered by French forum Worldscoop, the details in the grayscale drawings match the color image from the infotainment software, giving us another look at hotly anticipated sedan that will infuse much-needed excitement into Acura's lineup. Even though the images show rear bumper cutouts plenty large enough to house quad pipes, the patent is presumed to show the standard TLX trim, not the Type S trim we know is coming. Even so, we can see plenty of Type S concept influence even with the less aggressive bodywork, such as the narrower upper grille and more pronounced lower grille, the garnish on the lower intakes, the side mirror design, and flared rear fenders. The rear end in the patent shows the same taillamps and decklid shutline, aero vents in the bumper, and the reshaped license plate holder moved from the trunk to the bumper.  The bodywork will sit on a new platform, and the bulk of betting money has Honda's 2.0-liter four-cylinder turbo four-cylinder from the RDX as the base engine. That mill making 272 horsepower and 280 pound-feet of torque in the RDX, compared to the 2.4-liter four-cylinder in the current TLX that makes 206 hp and 182 lb-ft. The Type S is expected to inaugurate a brand new 3.5-liter twin-turbo V6 developed specifically for Acura with more than 350 hp, a meaty bump beyond the 290 hp and 267 lb-ft in the present range-topping 3.5-liter V6. The TLX comes in two standard flavors now, so the question is whether Acura will give the 2021 model another engine or output option between standard and the Type S. The MDX Sport Hybrid crossover fits a 3.0-liter V6 powertrain producing a combined 321 hp and 289 lb-ft. On the 2021 TLX, a 10-speed automatic will manage shifting duties, sending power either to the front wheels or to all four through Acura's Super Handling All-Wheel Drive.  The automaker had planned on debuting the car at the New York Auto Show, and the rescheduled debut will come online and is likely not far away. If Acura doesn't show the Type S at the same time, an unveiling of that should come by early next year. Related Video:    

10 automakers sued over keyless ignitions

Keyless ignition has rapidly proliferated throughout the auto industry to become a fairly normal feature on new cars. It's supposed to offer the convenience of keeping the fob in your pocket and just pressing a button to drive away. However, ten major automakers are now being sued in US District Court over claims that the system is dangerous, Reuters reports. The suit alleges that people are forgetting to shut off the engine, and the lack of an idle timer is the cause for 13 deaths by carbon monoxide poisoning and multiple injuries. The suit currently includes 28 plaintiffs, according to Reuters, but the lawyers are asking for class-action status to potentially add many more. The case goes after a major swath of the industry, including BMW, Daimler, FCA, Ford, General Motors, Honda, Hyundai, Nissan, Toyota, and Volkswagen, plus their related brands like Acura, Infiniti, Mini, and Lexus. In all, over five million vehicles are affected. The assertion here is that people walk away from their vehicle without shutting it off because they believe the engine shuts off automatically. If parked in a garage, carbon monoxide can build up, leading to poisoning. The lawyers claim automakers know this is a problem and also cite 27 complaints to the National Highway Traffic Safety Administration about the issue, according to Reuters. The plaintiffs are asking for an automatic shut-off and damages from the companies. These concerns have come up before, though. Toyota previously faced a lawsuit over a carbon monoxide death after a woman accidentally left her Lexus running. Also earlier this year, GM recalled 64,186 examples of the 2011-2013 Chevrolet Volt because owners weren't shutting them off. The problem resulted in two injuries, and the company released a software update to limit the idling time.

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.
