Honda debuts NSX Concept-GT hybrid racer

Not to be outdone by Lexus and its new LF-CC racecar, Honda is also bringing a little more excitement to the Japanese Super GT racing series with its NSX Concept-GT. Yes, just like the original NSX, this racecar will wear the Honda badge in its home market when it replaces the current offering in that series, the non-production HSV-010 GT, which itself replaced the NSX in the series back in 2010.
Looking exactly how we'd imagine a race-prepped 2015 Acura NSX to look, this racer is mean and sexy at the same time, and it will be powered by a racing hybrid system with a turbocharged four-cylinder mounted behind the driver. No word on power output, but it will compete in the GT500 class, which restricts power output to 500 horsepower. Unlike the Lexus racecar, the Honda NSX Concept-GT will being competing this season starting with this weekend's race at the Suzuka Circuit before running the full 10-race 2014 season. Scroll down for the short press release.

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.

2020 Acura TLX PMC Edition will be hand-built alongside the NSX

At next week's 2019 New York International Auto Show, Acura will reveal a pair of new models, the 2020 TLX PMC Edition and MDX PMC Edition Prototype. The duo will be limited-run models that get final assembly at Honda's Performance Manufacturing Center (PMC) in Marysville, Ohio, along the same production line as the Acura NSX. The TLX PMC Edition goes on sale this summer with a starting price of around $50,000. Production will be limited to just 360 models hand-assembled over a six-month period. The production version of the MDX PMC Edition will be built sometime after the TLX PMC run is complete. Think of the TLX PMC as an A-Spec performance model with features available with the Advance Package like a surround-view camera, heated rear seats, a heated steering wheel and power folding mirrors. Currently, the two packages are mutually exclusive. There are no performance upgrades beyond what the A-Spec already offers. Power from the 290-horsepower 3.5-liter V6 is sent to all-four wheels through a nine-speed automatic. The TLX PMC uses Acura's Super-Handling All-Wheel Drive (SH-AWD) to manage the power at each wheel. It also gets the A-Spec's stiffer dampers and quicker steering ratio. 2020 Acura TLX PMC Edition View 11 Photos The exterior design, too, is based on the TLX A-Spec, with a restyled front bumper, dark chrome trim, larger exhaust tips and a black spoiler. Likewise, the interior is based on the A-Spec trim, with heated and ventilated front sport seats, leather and Alcantara seating, a black leather steering wheel, a black headliner, a red instrument cluster and red accent lighting. Black 19-inch 10-spoke wheels and Valencia Red Pearl paint are exclusive to the TLX PMC. The paint uses mica, metal flake and super-high transparency nano pigments to give it a richer color and was previously only available on the NSX. The roof panel, door handles, grille and lower bumper are also gloss black. What makes the TLX PMC Edition (as well as the future MDX PMC) truly special is the hand assembly. Basically, the body-in-white (a basic unfinished unibody) will move from the main assembly plant in Marysville to the nearby Performance Manufacturing Center. There, workers will install the drivetrain, suspension, wiring harnesses and electronics. The car then goes to the paint booth before the interior is installed.
