Acura preps ILX for endurance racing challenge

Acura has used the occasion of this year's SEMA show to unveil a 2013 ILX that is remarkably different from the road-going car that we are familiar with. A far distance from the rather mildly performing street car, this ILX Endurance Racer is actually prepped to race at the grueling 25 Hours of Thunderhill in Willows, California.
The ILX racers (Team Honda Research has prepped two of them for the race) have actually each been constructed using two donor ILX sedans: one body-in-white chassis and one full production-spec car that donates powertrain, interior and electronic components. Overall, increasing the performance of the car was done mostly through extensive weight reduction rather than bumps in power. No figures have been given for the output of the ILX's K24Z7 engine, though we are told that a custom intake and exhaust have been fitted, as well as a racing flywheel.
A prominent LED lighting system dominates the front fascia of the ILX, along with a huge front splitter, while a massive wing speaks to the intentions of the car.

2019 Acura NSX vs. 1991 Acura NSX | Respect your elders

A car that forces the competition to head back to the drawing board does not come around often, especially when that competition happens to be Ferrari. Honda achieved such a feat back in 1991 when the original NSX was set loose in the supercar world. Not only did the NSX smack its contemporaries down in terms of performance and technological prowess, it also forced the Italians to make supercars with some semblance of reliability and manners. Spend only a few moments in an original NSX, and its specialness is palpable. The lack of power steering is acutely noticeable at low speed as I roll over little cracks and dips in the road, while the sticky rubber chucks small rocks up into the wheel wells. A near 360-degree view is at my disposal with the bubble-like canopy, and the ground right in front of the nose is visible from my vantage point. This is what control feels like, and we haven't even gotten to the reverie-inducing VTEC noises getting piped right into our eardrums yet. There are no dials to change the throttle response, no buttons to make the steering artificially heavy, no shift paddles behind the wheel to tell a computer to swap cogs. To my right is a manual shifter that can legitimately be described as perfect. This is a 1991 Acura NSX, and it is glorious. For some of the reasons I've briefly described, and plenty more, this car has reached legend status amongst enthusiasts. In the early 2000s it was a sales disaster, outgunned by pretty much every other supercar in the space. Honda/Acura was only working with a 3.2-liter V6 making 290 horsepower when that car finally met its maker after the 2005 model year. As collectable modern classics, the relatively low power output doesn't seem to bother folks spending close to, and over, six digits on low-mileage examples of these cars. What changed? Well, the passage of time tends to be the biggest factor in these things. Also, there's a new NSX out there, reminding the world that the old one exists. And just like when Acura discontinued the original, the new one is mighty expensive, selling in extremely low numbers, and generally regarded as lesser than other options in its class. This time around it has to deal with standout cars like the 911 GT3, McLaren 570S and Audi R8 V10. But perhaps even worse than that, the new NSX must withstand comparisons to the original. Can you think of any other legendary Japanese car with a similar image problem today? Yeah, the Toyota Supra.

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.
