We’ll start with the performance upgrades first. This is so far limited to some ECU tweaks and a quadruple tailpipe sports exhaust system. The petrol powered front wheel drive S60 2.0T version gets boosted from 250bhp/300Nm to around 297bhp/350Nm and the all-wheel drive 3.0 T6 version gets an additional 30bhp to its standard 304bhp and a massive 463Nm of torque. Up from an already mega (for a Volvo) 440Nm previously.
Heico had stated that the power upgrade in the T6 allows the car to reach 100km/h from a standstill in 5.8seconds. This figure is a whole second faster than the standard T6. The maximum speed is however unchanged and still limited to 250km/h, which is fast enough for most people, mind you.
As for the looks and handling, there is a 2 piece front spoiler, a rear diffuser (with optional carbon fiber inserts), a small bootlid spoiler, 18 or 20 inch wheel and tire packages and lowering springs (which benefits handling a smidgen). The interior mods are pretty tame. The S60 only gets an aluminum pedal set and a gear shift knob.
Pretty cool for a Volvo nonetheless.
