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.

New TLX A-Spec leads Acura's three-car Pike's Peak attack

Once again, Acura is headed to Pikes Peak for the hillclimb on June 25 with a small group of machines. This year the focus is on the TLX, with two vehicles bearing the sedan's name and shape. The two cars are very different, though, and will compete in two different classes. The first is the TLX A-Spec. This started life as a production TLX, but the 3.5-liter V6 has been reworked with pistons, rods, camshafts, and a valvetrain from Acura's TLX GT race car. The engine also has a turbocharger, which helps the V6 make an impressive 500 horsepower. All those ponies go to the front wheels through a limited-slip differential. In addition to the powertrain upgrades, the interior has been gutted, and a big wing and front splitter fitted. The A-Spec will compete in the Pikes Peak exhibition class. The other TLX is a TLX GT. This is the type of car from which the A-Spec borrows engine components, but not the TLX GT's twin-turbocharger system. TLX GTs have already been competing in motorsports, specifically in the Pirelli World Challenge. Acura did make some changes to this car for Pikes Peak, though. The suspension and engine computer have been tweaked, gear ratios shortened, and additional aerodynamic bits added for more downforce. The TLX GT will compete in the open class. Despite the focus on the TLX, Acura is still bringing an NSX to the hill climb. This car is similar to the one that raced in the Time Attack 1 class last year, but has some changes for the Time Attack 2 class. Most notable of these changes are the massive rear wing and front splitter. According to Acura, these aerodynamic aids were based on those used for the NSX GT3 race car. Acura also reduced weight, changed the tuning on the engine computer, and fitted sticky R-compound tires.

2021 Acura TLX to start at $38,525, hits dealers this fall

The 2021 Acura TLX will start at $38,525 (including a $1,025 destination fee) when it arrives in dealerships this fall. The flagship Type S model, which will be powered by a twin-turbocharged V6, will not arrive until spring, and while Acura has not yet finalized pricing, we're told it will start above the $50,000 mark.  The $38,525 base price of the 2021 TLX makes it $4,500 more dear than the model it replaces, but competitive with most of its luxury peers, largely thanks to its far more potent base engine. In fact, the 272-horsepower 2.0-liter turbo mill in the 2021 model in only down 18 horsepower from the V6 offered as the upgraded engine in the 2020. The new also TLX gets an updated platform that brings back its traditional double-wishbone front suspension, introduces a new turbocharged four-cylinder engine, and marks the return of the sporty Type S to the model lineup. To further make up for the rather large price increase, Acura has seen to it that the TLX is more feature-rich pretty much across the board. For example, base models now get a 10-speaker audio system with twin subwoofers and 12-way powered front seats. All models also come standard with Android Auto and Apple CarPlay integration for 2021. We'll come back to the Type-S momentarily; first, here's a breakdown of 2021 TLX pricing with destination included: 2021 TLX 2.0T — $38,525 2021 TLX 2.0T with Technology Package — $42,525 2021 TLX 2.0T with A-Spec Package —  $45,275 2021 TLX 2.0T with Advance Package — $47,325 A-Spec models are focused on sporty appearance and handling add-ons, while the Technology package is geared more toward those who want more convenience features. The Advance trim effectively blends them together and adds more premium features, such as Milano leather seating surfaces, heated seats and a heated steering wheel. Acura's Super Handling All-Wheel Drive system (SH-AWD) is available across the lineup for $2,000.  As for the 355-horsepower Type S model, Acura says it won't appear in showrooms until spring 2021, and while pricing has yet to be finalized, Acura says it will cost more than $50,000. That tracks, considering the Advance Package with SH-AWD is already a $49,325 car. Related Video: 2021 Acura TLX unveiling
