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.

2015 Acura TLX priced from $30,995*

Following a delay this spring, Acura is now ready to launch the 2015 TLX sedan this August, with pricing now confirmed to start at $30,995, *not including $895 for destination. This base MSRP is just $360 more than that of the outgoing TSX sedan; the TLX replaces both the TSX and TL in Acura's 2015 model year lineup.
That's a pretty fair deal considering that introductory price gets buyers a front-wheel drive TLX with a 2.4-liter inline four-cylinder engine with 206 horsepower,mated to a new eight-speed dual-clutch transmission, and featuring the automaker's Precision All-Wheel Steer (P-AWS) system. Adding a Technology Package ups the MSRP to $35,025.
Of course, the TLX is also available with a 290-horsepower, 3.5-liter V6 mated to Acura's new nine-speed automatic transmission. The TLX V6 P-AWS starts at $25,220 and climbs to $39,250 with the Technology Package. The bottom line on the range-topping Advance model is $42,500. Acura's Super-Handling All-Wheel Drive is available with the 3.5-liter engine, too - the SH-AWD Technology model starts at $41,450, while the SH-AWD Advance commands $44,700.

Acura TLX GT Racecar bringing the 'X factor' to Pirelli World Challenge

One doesn't normally think of Acura offering anything to mix it up with the SRT Viper, Lamborghini Gallardo, Mercedes-Benz SLS AMG, Nissan GT-R, Audi R8 and Ferrari 458 Italia (at least while the NSX is still off in the ether), but that's exactly what's about to happen. Honda's premium outpost is jumping into the top tier of the Pirelli World Challenge with this 2015 TLX GT.
The surprise reveal of this racecar at today's Detroit Auto Show will be campaigned by RealTime Racing, no stranger to racing Acuras, in the GT class (previously, the team had campaigned the series a rung down in GT-S).
The racecar is powered by a twin-turbo variant of the direct-injected V6 to be found in the production TLX sedan, right along with its Super-Handling All-Wheel Drive system. There's no word on how much power this HPD-massaged engine will put out in race trim, but we won't have to wait long to hear it fire up - the car is set to take to the track with team owner Peter Cunningham at the wheel in the next few weeks.
