TG drives the Porsche Boxster S
Can the King of the Roadsters grow up without selling out? We headed to the Black Forest to find out...

There's standard PSM (Porsche Stability Management) as well as the aforementioned options like PASM (Porsche Active Suspension Management) and PTV (Porsche Torque Vectoring). PSM deals primarily with stopping you hitting things, PASM mitigates bumps and PTV maintains drive. Basically the PTV is a partner to the Boxster's mechanical differential. Punt the car into a hard corner, and the PTV system brakes an appropriate rear wheel and directs excess torque to the opposite wheel via the locking diff, like a very sophisticated fiddle brake. Ever seen a tank turn around? Well, this is basically a brainy version of the same thing - pivoting the car around a point some way away from the steering front wheels. In slower corners - and if you're looking for it - you can just feel it working. I'm just not sure the Boxster needs it. I found several greasy hairpins up in the mountains where the little Porsche (PSM and traction disabled) found a neat balance, and it didn't seem like the PTV was interfering too much anyway. Mind you, that might just be because it was very subtle.
