Autoblog Minute: VW finds CO2 'irregularities', Takata dropped by automakers, SEMA recap

Volkswagen's diesel emissions scandal gets a new wrinkle, US regulators hit Takata Corporation with a substantial fine, and we head to Las Vegas for a look at tuner paradise at the 2015 SEMA show. Autoblog senior editor Greg Migliore reports on this edition of Autoblog Minute Weekly Recap. Show full video transcript text [00:00:00] Volkswagen's diesel emissions scandal gets a new wrinkle. US regulators issue a significant fine to Takata Corporation. And we take a peek inside tuner paradise at the 2015 SEMA show. I'm senior editor Greg Migliore and this is your Autoblog Minute Weekly Recap. The VW diesel emissions scandal, first brought to light in September, gets a new wrinkle, as an internal investigation by the German automaker revealed [00:00:30] irregularities in CO2 emissions that could affect approximately 800,000 vehicles. VW estimates the issue could pose a 2-billion euro economic risk. VW claims that most of the vehicles affected have diesel engines, but industry analysts say a 1.4-liter gas engine is also affected. VW says that fuel consumption figures were set too low during the CO2 certification process. During all of this, sales of some diesel-powered Volkswagen, Audi, and Porsche models [00:01:00] have been halted. Takata Corporation is back in the news in connection with its deadly airbag scandal. Federal regulators fined Takata $70 million. If the parts supplier does not comply, the fine could balloon to $200 million. Takata was also dropped this week by its biggest customer, Honda. And now, Toyota and Mazda will be following Honda's lead in dropping Takata. We're also hearing that Mitsubishi and Subaru are considering a switch in air-bag inflator suppliers. SEMA 2015 [00:01:30] came and went. We saw offerings from Mopar, like the AWD Challenger concept. Honda unveiled a Ridgeline that it will race at the Baja 1000, which gives us a hint at what future production model could look like. The celebrity presence was also felt in Vegas as it always is. Kid Rock brought a Duramax Diesel Chevy Silverado, and Acura restored and presented Ludacris with his now famous 1993 Acura Legend. Those are the highlights from the week that was. Be sure to come back on Saturday for my full recap, [00:02:00] where I'll have some added insight into Hyundai's foray into the luxury sector. For Autoblog, I'm Greg Migliore.

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.

2021 Acura TLX revealed, finally looks like a credible luxury sports sedan

We've been given our first official glimpse into the brand-new 2021 Acura TLX sedan, and so far we like what we see. It's clear that Acura wants to be considered a brand that focuses on performance, boosting power with two turbocharged engine options and the return of the Type S variant after a decade-long absence. Acura stuck close to the well-received Type S concept when styling the new TLX, which means the sedan boasts crisp lines, aggressively creased sheetmetal and a low, wide stance. An angular grille is flanked by Acura's Jewel Eye headlights and Chicane LED running lights to create an expressive face, and similarly shaped taillights at the back end finish off a cohesive design. An A-Spec sport package adds darkened elements along with a unique set of 19-inch wheels and a rear spoiler. The 2021 Acura TLX Type S goes several steps past the A-Spec with a so-called Diamond Pentagon grille and larger side air intakes. A front splitter and rear diffuser join the requisite rear spoiler to round out the aero package. Quad exhaust tips and 20-inch wheels are also included as part of the package. But the big news is underhood, with a 3.0-liter turbocharged V6 serving as the headliner. Acura hasn't yet released power figures for the Type S, but promises it will be much more powerful than the outgoing 3.5-liter V6 with "a more than 50-percent increase in low-end torque."   Related: 2021 Acura TLX vs. luxury sedans: How they compare on paper   Standard TLX models will get a new 2.0-liter turbocharged four-cylinder engine that produces 272 horsepower and 280 pound-feet of torque. That's 66 hp and 98 lb-ft more than the previous naturally aspirated 2.4-liter engine, and Acura says there are 123 additional lb-ft at 1,500 rpm. Both engines will send their ponies through a 10-speed automatic transmission. Front-wheel drive is standard, and Acura's fourth-generation torque vectoring Super Handling All-Wheel Drive system will be standard on the Type S and optional on other TLX models. Inside, all TLXs get a tech-rich cabin that features a centrally mounted 10.2-inch display and Acura's latest True Touchpad Interface. A 7-inch digital screen in the gauge cluster is standard, and a 10.5-inch head-up display is optional. Acura's Integrated Dynamics System is controlled via a prominent silver dial, and it now offers a customizable Individual mode.
