We drive the Acura TLX-GT racecar

Don't break the car. As you can tell from the video, that's the theme of the day at Gingerman Raceway in South Haven, MI. After two short lapping sessions in the Acura TLX-GT fear gave way to familiarity, and a second theme emerged: this is awesome. The anxiety was appropriate. There are only two TLX-GTs in the world, and both were at Gingerman that day. A mishap would potentially put either Ryan Eversly and Peter Cunningham out of contention for the subsequent Pirelli World Challenge race. I did not want to be that guy. But back to the awesome part. The TLX-GT is barely TLX, but more Acura that you might expect. The wheelbase, roof, and doors are all stock dimensions, although all the bodywork is carbon fiber. Out go the front MacPherson struts, in goes a special double-wishbone suspension. All-wheel drive comes from an XTRAC six-speed sequential transmission originally developed for Dakar Rally vehicles. The side mirrors are stock. Under the hood lies a 3.5-liter twin-turbo V6 with a stock block, head, crank, and throttle body. "Under the hood" is a generous term, though, because half of the engine sits inside the cabin. The front end of the block is aft of the front axle - the rest of the hood is taken up with radiators and hoses. To service the turbochargers, the RealTime mechanics remove the top of the dashboard. The front-mid engine location pushes the driver's seat back to the B-pillar, so you sit like Hightower from Police Academy. Only with less visibility. This does not calm the nerves. Nor does the din of 600 or so unmuffled horsepower. My first laps were understandably timid. But the TLX-GT is actually easy to drive. You get used to the low, rearward seating position almost immediately. Once rolling you don't need the clutch for shifts - just bang the right and left paddles to go up and down. I even became accustomed to the acceleration. At more than 3,000 pounds curb weigh the TLX-GT is quick, but not as explosive as cars like the Chevrolet Corvette Z06. Where the TLX-GT blows away road cars is in grip and braking, neither of which I fully exploited. The brake pedal is so hard you feel like you're standing on it just to get the pads to bite. Once engaged, they're like an endless well of deceleration, with ABS somewhere down at the bottom of the abyss. Second lapping session over, car returned intact and adrenaline high in full effect. I had the uncontrollable urge to get back behind the wheel. I mean, I barely had time to get up to speed.

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.

2022 Acura RDX First Drive | RDX redux gives us what we want

LOS ANGELES — AcuraÂ’s most recent totally new models — the TLX and MDX — thwacked us upside the head with authority to let us know that Acura as a luxury and performance brand is well and truly back in great form. The redesigned RDX tried to do the same back in 2019, and while it was an above-average overhaul effort, it didnÂ’t move us as strongly as the TLX and MDX have since. Now, the 2022 Acura RDX is here, and itÂ’s packing a bunch of improvements to try and both enhance the driving experience and ensure that it isnÂ’t playing second fiddle to other Acura products in tech or luxury. The one omission, and itÂ’s a big one, is the continued lack of a Type S variant. Both the TLX and MDX offer a high-performance Type S version with turbocharged V6 engines, and the RDX continues to go without such a model in 2022. ItÂ’s a shame, because the RDXÂ’s smaller size means it could serve as a quality platform for a performance crossover to compete against others like the BMW X3 M40i, Mercedes-AMG GLC 43 and Audi SQ5. ThatÂ’s not to say that Acura has neglected the driving experience for 2022. The one performance improvement comes in the form of re-tuned adaptive dampers on the Advance trim that are both stiffer in Sport mode and softer in Comfort mode. Plus, the cabin is much quieter than it was before thanks to additional sound deadening material and an enhanced Active Sound Control system. Acura says the standard car offers a 20% NVH improvement, while the Advance Package cars have even more sound deadening to deliver a 30% improvement over the 2021 model. YouÂ’ll be able to tell the updated RDX apart from the pre-refresh version by looking at the new grille pattern and thinner chrome grille surround. Look further downward, and youÂ’ll notice larger side intakes and a new fog light design. ItÂ’s harder to tell that anything is new from the back, but look closely, and youÂ’ll see a redone lower bumper and rectangular exhaust outlets on every model but the A-Spec — that hangs on to its round dual exhaust tips. A couple of new wheel designs round out the exterior updates, while the interior sees a new bronze-like finish for the aluminum trim in lower trims. Perhaps one of the most vital changes Acura made to the RDX this year is done on the equipment side, as it fixes one of the gripes weÂ’ve had with Acuras over the past couple years. You can finally equip the Advance Package onto A-Spec trim cars.
