The Acura NSX has been on sale since the 2018 model year, but the Japanese automaker needs to do something drastic to boost sales. Just 170 NSX models were sold in 2018, increasing to 238 in 2019. Expanding the lineup would no doubt increase interest in Acura's mid-engine supercar. There have been rumors that Acura is cooking up a hot Type R version of the NSX with more power and sportier styling, but nothing has been officially announced yet.

But what about the long-awaited convertible version of the Acura NSX? Rumors about a topless Acura NSX have been circulating for years now ever since the Acura NSX Roadster Concept was made for Hollywood blockbuster 'The Avengers' back in 2012.

Back in 2018, rumors suggested the production Acura NSX Roadster was going to make its world debut by the end of that year, but Acura still hasn't officially announced anything. This latest rumor suggests that the Honda NSX Spider will debut in June 2021. Potentially, it could debut at the 2021 Detroit Auto Show since the American motor show has moved from January to June from this year, but this seems too faraway considering how late this will be in the current Acura NSX's model lifecycle.

That said, Acura has been caught testing a prototype NSX believed to be the more powerful Type R, so new NSX variants could still be on the horizon. Hopefully, it won't be long until a camouflaged Acura NSX Spider prototype makes its spy photo debut.

If Acura is planning to put an NSX Spider into production, it will no doubt share the same 3.5-liter turbocharged V6 hybrid setup as its fixed-roof sibling, which produces 573 hp and 476 lb-ft of torque. 0-62 mph in the Acura NSX takes three seconds flat before reaching a top speed of 191 mph. Due to the extra strengthening required that will inevitably add extra weight, the Acura NSX Spider will be slightly slower off the line.
