Second-generation Acura TLX could inaugurate a turbocharged V6

The second-generation TLX will inaugurate a turbocharged V6 engine developed specifically for the Acura brand, according to a recent report. The six will power a range-topping, performance-oriented variant of the sedan. Honda's luxury division gave us a thinly-veiled preview of the next TLX when it introduced the Type S concept (pictured) at The Quail in 2019. While technical details were left out of the announcement, Car and Driver learned from sources familiar with the company's plans that the sedan will receive a new V6 whose displacement will likely check in at 3.0 liters. It will reportedly make over 300 horsepower thanks to at least one turbocharger. The 3.0-liter will replace the 290-horsepower 3.5-liter V6 available in the current-generation TLX. Several members of the Honda range also use the bigger six, it's notably found in the Ridgeline pickup, but none will receive its replacement; it's Acura-specific. Transmission options remain unconfirmed. C/D added the TLX will receive a turbocharged, 2.0-liter four-cylinder as its entry-level engine. It's related to the four that powers the Honda Accord, and it will spin the front wheels via a 10-speed automatic transmission. All-wheel drive will be offered at an extra cost. The sedan will ride on a new platform, and it will drive better than its predecessor regardless of cylinder count thanks in part to a comprehensively redesigned front suspension. Earlier spy shots depicting heavily-camouflaged test mules suggest the next TLX will look a lot like the Type S concept. It will take Acura's design language in a more evocative direction that will permeate the rest of the range in the coming years. Inside, motorists will find a touchpad-controlled infotainment system like the RDX's. Acura resorted to automotive omerta when asked to confirm or deny the rumors. The company simply told Autoblog it will introduce two new vehicles in the next 12 or so months and unveil a brand-exclusive turbocharged V6, which adds credibility to the report. We'll need to muster a little bit more patience to learn more. Related Video:     Featured Gallery Acura Type S Concept photos View 16 Photos Rumormill Acura Sedan

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.

Acura NSX GT3 racecar bares all in raw carbon

Acura slowly and dramatically revealed the NSX over a period of years. There were previews, concepts, and lots of teases before Acura finally showed us the whole thing. It's a different story for the racecar. And today, the wraps come off the FIA GT3-spec NSX to show all of its bare-carbon glory. The NSX GT3 strips away more than just the paint from the standard road car. The racecar comes sans hybrid system, meaning all the power from the twin-turbocharged 3.5-liter V6 is sent solely to the rear wheels. Modifications to the body include a large rear wing, underbody diffuser, and bigger hood vents for engine cooling. While the hybrid system may be gone, the NSX GT3 uses the same block, heads, valvetrain, crankshaft, pistons, and dry sump lubrication system as the road car. Power is sent through a six-speed sequential gearbox instead of the road car's nine-speed. The NSX GT3 will be built alongside the street version in Ohio. Honda engineers in Japan and North America shared in the development. Final GT3 homologation will be completed by the company's Honda Performance Division in Santa Clarita, CA. Related video:
