Very interesting...we seem to get more info each day...
2. It Has a Torsen Limited-Slip Differential
Tada-san prefers the quicker reactions of a clutch-type limited-slip differential but settled on a Torsen gear-type differential because of its progressive engagement. There's also a brake differential built into the stability control system's operation which Tada-san says reacts faster than the Torsen anyway. But when stability control is fully disabled (by pressing and holding the traction control button for 3 seconds) the brake differential is gone as well.
And that's when the magic happens anyway, right?
3. There's Solid Evidence a Turbo Is Coming
Tada-san tells us the FR-S's Aisin-built six-speed manual has headroom to handle more torque, but he won't reveal how much. Still, his conspicuous laugh tells us there's enough to accommodate turbocharging.
The primary benchmark for the FR-S was the Porsche Cayman.
Also, for a car with a flat engine the FR-S's hood line is awfully high. Forward visibility isn't as good as we imagined it would be in a car with this layout. But this might be a worthwhile compromise.
A quick look under the hood reveals several inches between the top of the intake manifold and the underside of the hood — probably enough to package an intercooler. It looks to us like there's enough real estate for a WRX-style intercooler mount with the intake manifold feeding from the rear instead of from the front as it does in normally aspirated trim.
