Acura NSX prototype gets back on track

Developing a new vehicle is not without its complications, we're sure, but usually things follow a fairly predictable progression: you develop a prototype, you test it, test it and test it again, then you put it into production. What you don't expect is that your prototype will burn to the ground, but that's what famously happened to the NSX which Honda engineers were testing a few months ago.
Fortunately, the Acura NSX prototype is back on track, both literally and figuratively, as you can see from this latest batch of spy shots snapped at the Nürburgring. This camouflaged prototype looks pretty much the same as the last one, only, you know... less crispy. Which is to say, it looks pretty much ready to hit showrooms.
The naysayers may point out that Honda chose colder and damper weather to put the NSX back into testing - thereby mitigating the risk of another fire - but we're sure the Japanese automaker has been working hard to fix the flammability issues, whatever may have caused them, over the past few months. At least, we hope they have.

Acura recalls 106K MDX models for AC system bolt

The National Highway Traffic Safety Administration is announcing a recall covering the air conditioning system on 106,439 units of the 2014-2015 Acura MDX. The affected examples have production dates between April 23, 2013, and December 16, 2014. While the problem doesn't create a major safety concern, it could be very annoying when driving during the intense heat of the summer months. On these luxury crossovers, the bolts on the air conditioning compressor clutch drive might not have the proper anti-corrosion coating. This makes it more likely for them to eventually break, and if that happens the AC pulley could fall off the CUVs. Acura reports no injuries or crashes form the issue, and the company discovered the issue through warranty claims for the air conditioning not working. To repair the problem, dealers will replace the bolts. They'll also inspect the AC clutch plate and will replace it if necessary, as well. The repairs for some owners should already be in progress, according to NHTSA.

Acura builds 345-horsepower RDX A-Spec for SEMA

The 2019 Acura RDX is great — a return to form for the sporty compact luxury crossover. So there's no real harm in giving one the SEMA treatment, especially since it entails a real motorsport tie-in and some legitimate performance parts. As for the giant graphics, well, it's SEMA after all. Graham Rahal races for Honda in the IndyCar series, and he also has his own performance parts company — named, sensibly enough, Graham Rahal Performance — which he started in 2017. They sell some private-label bits manufactured by other companies to their spec, some off-the-shelf parts, and they do tuning and installation work on customer cars. Acura gave the job of building the SEMA RDX to Rahal. There's a fair bit going on under the hood to get the RDX to 345 horsepower from the factory 272 ponies. The 2.0-liter turbo engine gets a bunch of enhancements. The turbo, intake, exhaust manifolds, downpipe, and cat-back (a GRP design) are all aftermarket. There's a customer intercooler, too. KTuning did the ECU with a custom map. On the handling front, the RDX wears Eibach springs, StopTech brakes, HRE wheels at 21 inches, and Michelin Pilot Sport 4S tires. The RDX started life as an A-Spec model in Apex Blue Pearl, and from there GRP applied carbon fiber garnish to the mirrors, grille accents, and lower fascia. Troy Lee Designs did the exterior graphics, and inside there's more carbon fiber and a custom steering wheel (courtesy of Max Papis's MPI Innovations shop). The RDX will be on the show floor if you'd like to check out the Rahal shop's handiwork. Related Video:
