True sports-car lovers drive their machines through all seasons, and Porsche has been touting the year-round abilities of its vehicles at least since it introduced the 964 generation of the 911 with all-wheel drive in 1991.

No, they don?t use Porsche SUVs, capable though they are; this version of the Porsche Driving Experience is for sports-car drivers. Programs are offered in five countries: above the Arctic Circle in Finland and in Switzerland, Italy, China, and Canada, the last of which we attended recently. Conducted at Quebec?s Mécaglisse motorsport complex, about a 90-minute drive north from Montreal, Camp4 Canada?s 2017 sessions start at a cost of a little more than $4000 U.S. (actual prices are in Canadian currency, so the precise figure depends on exchange rates on the day you pay). That?s for the basic two-day Camp4 program; the top of the range, the three-day Camp 4RS, costs nearly $5700. Bridging the gap is Camp4S, a roughly $5000 three-day program. In order to sign up for Camp4S, customers must have previously completed an entry-level Camp4 class.
