It is no exaggeration to say that the Scion FR-S / Toyota GT86 has single-handedly succeeded in injecting some sparkle into Toyota's lackluster lineup. And according to a source close to Toyota, there's plenty more where that came from.

That's right folks, the GT86 family -- sold in America as the Scion FR-S and its twin, the Subaru BRZ -- is about to grow, and in a big way. When the rear-drive sports car landed in showrooms last year to massive praise from auto critics, we were told of other iterations including a soft-top, a sedan and a shooting brake (sports wagon). GT86 chief engineer Tetsuya Tada even mentioned as much in his blog. Well, our insider now tells us that the green light has been given for a GT86-based sedan.

An FR-S convertible concept was rumoured for this year's Geneva Motor Show

in March, but as of October, there is still no word from Toyota, or our insider for that matter, as to when we might see that car.

What we can tell you is that a GT86-based sedan, very much like that in our artist's impression, is on the way, and may even beat the convertible into showrooms.

According to our source, the new sports sedan will target buyers in their 40s who honed their driving skills on cars like the rear-wheel-drive Corolla AE86, Nissan Silvia (180SX and 200SX), Mazda RX-8 or Honda S2000.

Employing a wheelbase that's 10 cm longer than that of the current FR-S, the new sedan will feature what Toyota calls a "keen-look" grille design that appears to replicate the shape of a Japanese "katana" Samurai sword.

In addition to the base model's Subaru-sourced 200hp 2.0 litre boxer powertrain, the as-yet unnamed-sedan will also offer a next-generation hybrid system. Strategically differentiated from the current THS hybrid system, the new 'Hybrid R' sports hybrid system will incorporate a one-motor setup that generates between 250-270hp while achieving 10-15% better fuel economy.

The boxer has widely been considered to be the weak link of the FR-S / BRZ, with critics and owners alike wishing for more power.

While Hybrid R details are still sketchy, our insider suggests that the new system will employ F1-style KERS (Kinetic Energy Recovery System) technology that can recover the car's kinetic energy under braking. This addition appears to be the reason for the longer wheelbase.

While we will not see this concept at the Tokyo Motor Show in November, we hear strong rumours that it will make an appearance at next year's Geneva show in March. Expect to see this all-new sedan in showrooms some time from late 2015 through early 2016 for around $30,000.

Notebook: Our insider also tells us that the planned Toyota-BMW jointly developed sports car will not be shown at the Tokyo Motor Show. Geneva next year looks more likely.
