A new concept could indicate the S2000 is on its way back to Honda showrooms.

Auto shows are about looking to the future, not the past, which has us curious about Honda's plans for the upcoming Tokyo Motor Show.

Honda's Tokyo Motor Show lineup includes the usual suspects, with both production and concept vehicles set to debut at the biennial show, but one planned reveal has piqued our interest - an S2000-based sports car.

Although the S2000 officially went out of production in 2009, Honda has announced it will display a concept based on the rear-wheel drive sports car at the 2013 edition of the Tokyo Motor Show.

Called the S2000 Modulo Climax - and tagged as an "exhibition model" - the concept car is virtually identical to the discontinued S2000. However, Honda has taken the time to update the car with new front and rear fascias, as well as a "chic interior coordinated in black and burgundy." No further details were given, leaving plenty of room for speculation.

It seems unlikely that Honda would reintroduce a vehicle that was beginning to show its age when it went out of production nearly four years ago, but the S2000 Modulo Climax could be an indication that a new version of the S2000 is under development. Honda was reportedly readying a new sports car to replace the S2000 in 2008 or 2009, but the economic collapse put the brakes on that project.

However, the economic outlook has improved over the last three years and rear-wheel drive cars like the Chevrolet Camaro, Hyundai Genesis and Scion FR-S have grown in popularity over that period. A new version of the S2000 would be the perfect vehicle to tap that market, but the question remains - will Honda actually build it?
