It may not seem like it, but the second-generation Acura NSX turns six years old this year. While there have been some updates over the years, including new colors and minor tweaks, the mid-engine sports car looks pretty much the same both inside and out. But spy shots of a camouflaged NSX indicate that an updated model could be arriving very soon. Better yet, it could even be a new high-performance variant.

Photos of a camouflaged orange NSX were posted on Instagram by user @nsxjon. From the looks of it, there will be a few changes to the front and rear bumpers. Unfortunately, there's only one close-up photo of the prototype, and it gives us a better look at the mystery NSX's rear end. Based on the photo, the rear bumper features wider vents and an integrated diffuser, making it look a lot more aggressive. However, the taillights and the lip spoiler appear to be identical to the current model.

As for the front end, Acura seems to have made some tweaks to the bumper to match the revised rear fascia. The intakes appear to be larger and split in two. Unfortunately, it's hard to tell if a larger splitter has been added to match the rear diffuser. Like the taillights, the headlights appear to be unchanged.

There are two possibilities as to what this mystery NSX could be. The first is that it is a facelift. Considering that the sportscar is now six years old, Acura may want to change its design to keep it looking fresh against its competitors. The other option is that it's a performance-oriented model. Given the mild changes, it's unlikely to be a new NSX Type R. Instead, it could be a trim similar to the Type S or Type S Zero from the original NSX.

Whether it's a facelift or a new performance-oriented model, it's great to see Acura showing some love for the NSX.
